You need to add your Adsense links right in the heart of your template or right in the heart of your content.
Link Units:
Since the introduction of Google Adsense "link units", we can now add what looks like a "menu system" to compliment our menu system within our website. This is HUGE. Have you ever just clicked on a website and kept clicking on the menu links? I know we all have. By adding a "Google link units" to your menu, you will get more clicks than you thought possible. Try adding the link units near the top for better performance and try creating your link units to match the color of your menu system in place. Once in a while I find myself clicking on a menu link unit without even realizing it which in turn gives more money to the website owner.
Leaderboards & Skyscrapers:
These may very well be your "bread & butter". I only say this because of the sheer size of these ads units. The best place to add these ad units is obvious; Straight across the very top of your website (leaderboards), and straight down the side of your template (skyscrapers). Anywhere else may not look proper within your template and may look unprofessional.
Square & Rectangle Ad Units:
These are great to compliment the mass amount of content within your website and also within your recommended resources. You want to compliment your content; you don't want Adsense to BE your content because this will look poor on your part. Square and rectangular units are great to use within articles posted on your website or within your link resources. Try adding your Adsense boxes above your resource links within a page to give your Adsense account that added extra exposure.
AdSense allows website publishers to display contextually relevant advertisements on their website. If a web visitor "clicks" on an advertisement, the web publisher will earn a percentage of the advertising revenue generated as a result of the click. Many webmasters have built content websites around the Google AdSense model. In many cases the specific intent of the webmaster is to profit from Google AdSense Other webmasters use Google AdSense to supplement their revenue. Regardless of the webmaster's intent, the following tips will help webmasters looking to profit from AdSense.
1.Niche Sites.
Targeted nice sites that have a clear theme, tend to generate more advertising revenue simply because it is easier to achieve decent search engine placement. Be warned though, you want to chose a niche where there is a sufficient number of advertisements available.
2. Target Keywords.
When determining the sites focus, consider how much the advertisers pay for the advertisements. If the site is focused on ringtones, like Ringtone Central http://www.ringtones-central.com the payout per click is going to be very small, as ringtones are not high ticket items, advertisers will not spend a lot on pay per click advertisements. With less obvious markets use Overture to determine how much advertisers pay per keyword, it is usually similar on Google. Search Overture for a keyword then click "View Advertisers' Max Bids" in the top right corner. This will show the Overture inventory and how much is paid per keyword. Because the market has become very competitive, it will be difficult to rank well in search engines with a new website that is optimized for the terms that have the highest payout. Consider targeting terms that are moderately priced.
3. Aged Sites / Time.
Over time as a website is spidered by Google, advertisements will generally increase in relevance. In general, older websites will rank better in search engines. The closer the advertisements relate to the webpage's content; the higher the "click-through" the publishers will see.
4. Coding.
In order to minimize a websites maintenance place the Google generated AdSense code in the website template or an include file. This will allow you to easily experiment with different advertisement sizes and ad placement, and keep the web maintenance to a minimum.
5. Tracking Channels.
In order to know how effective a specific website or ad placement is use distinct channels and subchannels within Google. This will allow you to discern what performs best on a specific website. Using channels will tell you what sites are making money, what advertisements are making money and what ad position is the most profitable on a specific website. Keep in mind that you should run an advertisement for a full week, in order to properly test its effectiveness, different days of the week will vary the web traffic so comparing one week to another will give the most accurate reflection of how effective a campaign performs.
When testing different advertisement sizes, placement or color schemes be sure to leave campaigns in place for one week, different days will often result in web traffic fluctuations. Comparing web traffic, week to week will give a clear indication of what ad formats perform the best.
6. Integrated Ad Placement.
Many webmasters have been successful at integrating advertisements into a website. The easiest way to integrate an advertisement into a website is to remove the advertisement border. This will allow the ads to better blend with the webpage. Google recommends contrasting the link colors with the website colors to increase click-throughs. It is also suggested that webmasters randomize the color of the advertisements, so that frequent users will not naturally "filter" the ads.
Example of integrated ad placement: http://moneyits4u.blogspot.com/
7. Number vs Value of Advertisements.
Up to three advertisements can be listed on each page. This decreases the value of the advertisements served, so publishers should cautiously add advertisement units, as it dilutes ad inventory. In other words you want to serve the most expensive ads at all times.
8. Hot Spots.
Like web copy above the fold holds true with AdSense as well. This means that advertisements that appear without having to scroll will be read more frequently. Hot Spots are areas on a web page that result in a higher percentage of click-throughs. According to Google the highest paying advertisements are located on the hot spots.
Google does not indicate if image advertisements or text ads perform better, so webmasters are encouraged to experiment with both.
9. Highest performing Ad Sizes.
According to Google the 336 x 280 rectangle, the 300 x250 rectangle and the 160 x 600 sky scraper result in the highest number of click-throughs. Depending on the website's design and layout, publishers may experience different results with different ad sizes, placements and color schemes. Expirement and track the results for each website to maximize the AdSense payout.
In PPC advertising industry click fraud is defined as clicks generated by
Competitors of advertisers: These parties may wish to harm a competitor who advertises in the same market by clicking on their ads. The perpetrators don't profit directly, but force advertiser to pay for irrelevant clicks thus weakening or eliminating a source of competition.
Competitors of publishers: These persons may wish to frame a publisher. It is made to look like the publisher is clicking on its own ads. The advertising network may then terminate the relationship. Many publishers rely exclusively on revenue from advertising and can be put out of business by such an attack.
Other malicious intent: As with vandalism, there's an array of motives for wishing to cause harm to either an advertiser or a publisher, even by people who have nothing to gain financially. Motives include political and personal vendettas. These cases are often the hardest to deal with, since it is hard to track down the culprit, and if found, there is little legal action that can be taken against them.
Unwanted "friends" of the publisher: Sometimes upon learning a publisher profits from ads being clicked, a supporter of the publisher (like a fan, family member, or personal friend), will click on the ads to "help". However, this can backfire when the publisher (not the "friend") is accused of click fraud.
Clicks generated by publisher: Some publishers try to generate clicks manually or with the help of computer programs to drive up their revenue.
Following tips will help you protect your Adsense account from click fraud if u doesn’t fall in the last category listed above.
1. Regular monitoring of traffic log and your adsense reports:
Monitor your adsense reports and your traffic logs regularly (at least once a day).If you do this regularly you will become familiar with your site's performance and you will be able to easily identify something strange and suspicious very easily. If you notice something strange in your reports or traffic logs you will have to report it to adsense support as soon as possible. You may include all the details you have from your reports or your traffic analysis tool. Suspicious activities can be something like a considerably high click through than you normally gets,conciderably high increase in page impressions received large number of clicks from a same IP etc.By sending an email with all the details you found you can notify Google about suspected invalid activity. In order to be able to be monitor your sites performance and the behavior of the visitor’s u will have to incorporate some kind of traffic analysis tools to your site. Google, Static is well known examples used by a large number of webmasters.
2. Be polite in forums:
This tip is only important for those who are promoting their websites through their signatures in different forums. If you act rude in the forums it is never going to help you, but it can sometimes put you in trouble. Think about this case, you behaved in a rude way to some other member in the forum and you have a link to your site on your signature and the angry member decides to click on your ads regularly and deliberately. This can send the wrong message to Google and sometimes they may think that’s it you who is doing the clicks or you have appointed someone to click your ads regularly and they might decide to ban you. so I’d advice you to be polite and helping in all the forums in which you are participating. If you can't help,atleast don't blame or make fun of anyone.
3. Don’t discuss your source of income (ad sense) with family, friends etc:
Don't tell your friends and family anything about how you are making money online or how your website is making money for you. Even if u decides to tell them make sure to tell them why they can't click on your ads. You will have to convince them that they clicking on your ads won't be a help for you and it will be harm. The problem with discussing this with your friends and family is that sometimes they will start clicking on your ads thinking that the are helping you earn some bucks. But you know that it can get you banned.
4. Stay away from illegal methods of traffic generation:
Invalid clicks or click fraud includes clicks from traffic generated using methods like Traffic exhange,PTC advertising, Auto surf etc.These type of traffic are blacklisted by adsenseTOS.So you must stay away from traffic generated by illegal methods. The above mentioned are just examples and the list is not limited to them.
5. Accidental click
Couple of weeks ago I wrote to adsense support about the impressions generated by me while updating my site. The reply I got from them said that a publisher is allowed to view his sites as much as they want provided that he\she is not clicking any of the ads that appear on his\her site, he\she is not refreshing the pages too often. So that clears things up.
What if you clicked on your ad accidentally? The answer is, You will have to write adsense support about this as early as you can. If you are interested in viewing and checking the ads on your site without creating illegal clicks you may use Adsense preview tool.AdSense preview tool is an addition to the right-click menu for Windows Internet Explorer 6.x, allowing you to preview the ads that may show on any web page. If you want to avoid complication of accidentally clicking on your ads you may disable ads for your computer.
Don't sit back and relax while your website is earning you money using adsense.You will have to work hard to protect that Source of income from threats like click fraud.
Following these simple rules will help keep your account in good standing:
1. Don't click on your own Google ads.
Clicking on Google ads on your own site for any reason is strictly prohibited. If you'd like more information about one of the advertisers appearing on your site, please type the URL of the ad directly into your browser's address bar.
2. Don't ask others to click on Google ads.
Users should click on Google ads because they're interested in the services being advertised. Encouraging users to click on your Google ads, both directly or indirectly, can lead to inflated advertiser costs and can cause your account to be disabled.
3. Don't employ pop-up prompts or automatic software installations.
Google is dedicated to improving the user experience on the Internet, and promoting responsible software principles is part of that effort. Sites showing Google ads may not prompt users to install software on their machines. Publishers must also not attempt to change users' browser home pages automatically or via pop-up prompts.
4. Be aware of how your site is promoted.
Pages showing Google ads may never be loaded in an unfrequented pop-up. This means publishers need to be very careful when purchasing traffic or setting up ad campaigns with third parties. Before contracting with any ad network, you should ensure that they will never display your site in pop-ups or as a result of the actions of any software application.
5. Don't place Google ads on sites that contain prohibited content.
Google ads may not be displayed alongside any type of content prohibited by program policies, including adult or mature content, gambling-related content, or drug content. It's your responsibility to ensure that all of your pages adhere to these policies.
6. Respect Google trademarks.
Framing or mimicking Google pages is strictly prohibited by our Guidelines for Use of Google Brand Features. In addition, publishers may not use any Google Brand Features such as Google trademarks, logos, web pages or screen shots, without prior consent from Google.
7. Don't tamper with the AdSense code.
AdSense offers a wide variety of approved formats, colors, and features in your AdSense account. Once you've generated your code, however, we ask that you do not alter any portion of the code or change the layout, behavior, targeting, or delivery of ads for any reason, unless specifically authorized to do so by Google.
8. Provide a positive user experience.
Sites that contain excessive pop-ups, use sneaky redirects to obtain traffic, or otherwise attempt to interfere with normal web navigation aren't permitted in the AdSense network. Please make sure your site doesn't deceive your users in any way. In general, it's a good idea to follow our Webmaster Guidelines on quality to ensure that your site provides a positive user experience.
9. Provide a good environment for advertisers.
Sites showing Google ads should not present a poor opportunity for advertisers. Sites that use tricks or deceptive practices in order to trigger inadvertent clicks on ads are prohibited.
10. Be responsive.
Publishers are asked to be responsive to emails sent by the AdSense team. Be sure to keep your email address up-to-date, in case we ever need to contact you about your account.
Before serving ads on a web page, check its keyword density. A free and advanced tool for finding the most prominent keywords in a page can be found here: SEO Density Analyzer. Copy the most important keywords to a text file ([web page name]-adsense-keywords.txt).
AdSense Tip #2: Improve your keywords
Get keyword suggestions from Overture Search Inventory and from Google AdWords Sandbox. Get new keywords that can help you improve your ad relevance. Enter the keywords from [web page name]-adsense-keywords.txt and save the suggestions to [web page name]-adsense-suggestions.txt.
AdSense Tip #3: Keep your website focused on a theme
Use the keyword suggestions to enhance your web pages and to build theme-based content. And also try to get your keywords into the anchor text of your incoming links as much as possible. Don't forget that Google AdSense is keyword-targeted advertising: Google AdSense bases its advert topics on your websites content, this means that content-rich websites of a popular topic should attract a large amount of ads.
AdSense Tip #4: Write a new page every day
One of the best tips is to add a new page to your web site every day. The more content you have, the more visitors you will get. Put an Adsense unit on each and every content page of your site. But where? You will find more about that from the next AdSense tips.
AdSense Tip #5: Choose the right AdSense format
Wider formats are successful because the ads are compact, easy to read and are complementary to the content. The top three AdSense formats are:
336x280 large rectangle
300x250 medium rectangle
160x600 wide skyscraper
Another successful format is the 468x15 horizontal ad links, that can be placed under your navigation bar.
AdSense Tip #6: Color tips
When creating your Google AdSense ads it is recommended to use the color scheme and style of your website so that the ads blend in well. Ads without background color and borders perfom better than ads within borders with background color.
Create a custom AdSense palette:
border color = background color of your web site
background color = background color of your web site
link color = blue, color of your links
url color = black, #999999
text color = black, #333333, color of your main content
You can also rotate your color palette: select multiple color palettes that blend with your site to create variety.
AdSense Tip #7: Position tips
Visitors tend to look at the big headlines to see if your page is worth reading. If you get them interested, they will read the text and look for your navigation links.
Place the AdSense ads in a prominent place around the top/left part of your page or under your headlines, where your visitors are most likely to look at.
If you have an article page with a long body of text, the bottom of that article is a good place for AdSense ads because your visitors read the text and then they want more resources.
AdSense Tip #8: Increase the number of ads, but not too much
If you have a lot of text on a page, use multiple AdSense units. You can use up to three AdSense units on a page, two AdSense search boxes and one unit of ad links.
Link units allow the user to refine what they're interested in. So if they may not be interested in specific ads on your page, they might be interested in a particular topic, and by clicking on a link unit and a link in the link unit, they'll be able to specify that they're interested in that specific topic and get a lot more options and variety on the ads that might appear.
AdSense for Search allows visitors to search Google.com or your sites (up to 3 domains). You earn money whenever they click on the ads that come up on the search results. If you click the Open search results in a new browser window checkbox in the AdSense for Search settings, you won't lose your visitors.
AdSense Tip #9: Preview Google ads
You can find out what ads will be served by Google AdSense if you install Google AdSense Preview Tool, a very simple tool available only for Internet Explorer 6.0. Click to advertiser sites without generating invalid clicks, and easily add their URLs to your URL filter list. Because AdSense uses geo-targeting, Google serves different ads for other countries. Instead of faking your IP or travelling abroad to test your ads, use this AdSense tool to see what ads see your visitors from France, Germany or other countries.
There may be no Google AdSense ads available for your webpage, so Googlw will display Public Service Ads. You can hide them using alternate colors or images. Make sure you include the image in a simple html file as a link (use target="_top"). The image size should be the same as the dimension of AdSense units. In the alternate url box, enter the absolute url of the html file.
AdSense Tip #11: Show images above or next to your ads
Placing images above AdSense ads is not necessarily prohibited by program policies. However, depending on the method of implementation this could be considered encouraging users to click on ads. So you should include a border line between the ads and the images. Don't show specific products in your images, in order not to mislead the visitors. Just use generic images that will increase the visibility of your ads.
AdSense Tip #12: Use section targeting
Use section targeting to emphasize some content in your page. On your site, place this code where you want to emphasize.
AdSense Tip #13: Alternate the colors of your ads
AdSense allows you to have up to 4 color variations for each variable for which you can specify color. You should do that if you put AdSense ads on pages that receive many impressions from the same visitors (for example forums) to reduce ad blindness. For example:
AdSense Tip #14: Your Google ads should be visible
Make sure your text ads are visible to the surfers in all screen formats. If you put the ads in a table, give sufficient breathing room, i.e. proper cell padding and cell spacing to make the ads stand out from the rest of your content.
AdSense Tip #15: Use AdSense channels
You can categorize the content of your website into channels and then track your performance. This way you can experiment with different types of ads and see which is performing the best. Instead of buying an AdSense tracker, you can enter the most important pages in your site and see how they are doing. Create up to 200 channels for AdSense.
Adsense Tip #16: Don't put ads on empty pages.
When I reworked my site, I built a skeleton set of pages that had no content, just titles and some meta tags. I displayed ads on those pages, however. Although all you see are public service ads at first, the very act of displaying ads on a page causes the AdSense web crawler to quickly fetch that page for analysis. A page with good content will thus begin showing relevant paying ads fairly quickly.
If you don't have any content, then, Google will have to guess as what your page is about. It may guess wrong, and so the ads that it displays may not be relevant. You'll have to wait until Google re-crawls the site for the ads to correct themselves. Here is what Google had to say when I asked them about how often the AdSense crawler updates a site:
Thank you for taking the time to update your site. New ads will start appearing on your site the next time our crawler re-indexes your site. Unfortunately at this time, we are unable to control how often our crawlers index the content on your site.
Crawling is done automatically by our bots. When new pages are added to your website or introduced to the AdSense program, our crawlers will usually get to them within 30 minutes. If you make changes to a page, however, it may take up to 2 or 3 weeks before the changes are reflected in our index. Until we are able to crawl your web pages, you may notice public service ads, for which you will not receive any earnings.
It's better to flesh out the page before you start displaying ads on it.
Adsense Tip #17: Don't be afraid to ask questions.
If you're wondering about something, don't be afraid to ask Google. So far, they've always responded to my questions within a working day. There are two email addresses to use, depending on the type of question:
Their responses are always very polite, and they appreciate getting problem reports and suggestions.
Adsense Tip #18: Avoid non-English characters on English pages
This one is a bug, to be honest. My surname is French, and I prefer to write it out correctly with the accent grave on the first "e". Every page on my site would then include at least two accented letters, because my name shows up twice in the footer. On some pages my name shows up two or three more times.
Placing a skyscraper above the fold on the left side of your forum seems to produce slightly better performance than other positioning. However, when using multiple ad units throughout the page our horizontal bias still favors the leaderboard. See the Forum Heat Map below for more details.
2. Display your ad units where repeat users will notice them
A leaderboard at the very top fits nicely next to the logo, but forum regulars tend to skip the header and go straight to the meat of the thread. Placing your ad unit above or below the first post can be more effective.
3. Place a leaderboard immediately after the last post
This provides users who make it to the end of a thread with a ‘next step’ when the content ends. If you place it after the footer, though, folks will move to the next thread before they even see the ad!
4. Use horizontal link units
Link units offer a wider range of relevant topics for users to browse. A horizontal unit can be placed near the top of your forum just below the header.
5. Opt-in to image ads
Supporting image ads increases the pool of ads –particularly cost-per-thousand-impression (CPM) ads – bidding to display on your site. Since forums tend to have lower click-through rates (CTRs) than other types of sites, CPM ads can improve revenue without the need for clicks. Please remember, however, that CPM ads come in both text and image formats.
6. Be sensitive to your forum community
Forums are highly interactive, so be sensitive to your users when implementing your AdSense ads. Be sure to blend the ads nicely, so they don’t appear overly intrusive – but don’t blend them so well they mislead your users! Every forum site is different and you know your community best, so as always use your own judgment to create the most positive experience for your users.
We all want to increase Google Adsense CTR i.e. click through ratio, because the higher times the surfer clicks the Adsense ad, higher is the payout to you.
How to get higher CTR?
1. Post Adsense ads them on text rich pages and make sure that Adsense had a bunch of keywords to work with. Getting Higher paying keywords is better of course.
2. Learn how to get rid of public service ads, which pay you nothing for your efforts.
3. Avoid titles like the approved ‘Sponsored Links’ and ‘Advertisements’ above the Adsense ads. Why do you want to tell the world they are ads when google already puts ‘Ads by Gooooogle’ with them. These two terms are the only ones allowed by Google TOS. Any other terms will get your account terminated.
Place Ads above the fold, i.e. you dont have to scroll down to see the ads. Moreover it loads before your entire page does.
Provide lots of free space around ads so that they stand out and users know where to find them
Experiment by changing the location of advertisements. Track them by channels to see which location works. Sometimes they can do wonders.
Many experienced Adsense users have reported better CTR with vertical ads rather than the horizontal ones. But that really depends on your site structure.
Usually it is recommended to place towers on your right, as users tend to use the mouse to scroll the bar on the right side wiht a higher chance to see your ads. Some have reported doubling CTR’s by placing towers to the left rather than the right, as people have got bored of seeing ads on the right, it has something to do with the sidedness of the brain which I do not understand and there is a tendency to read from left to the right.
Many sites will have small ads in the top right hand corner, as they claim it is the first place where the eye sees.
Match the colors of your ads with the colour scheme of your site. Blending with your sites color profile helps to identify them not as ads, but as links similar to those of your site. The more the AdSense looks like part of your site, the higher CTR you will get.
Blend ads with your page - remove the borders by having a similar color as your background helps to show ads as being part of your site. Do not blend text or the ‘Ads by Gooooogle’ with your background as it is against Google TOS. However, such blending may not work for you always due to banner blindness. Neither do they see the ads, not do they click on them. So a contrasting ad may suit your site better.
Experiment by changing the colors, background of advertisements. Sometimes they can do wonders.
I hope these tips help to get your Adsense CTR up by at least 100% if not more.
Google Adsense program is a popular web advertising program which provides a good income source for many websites. There are well defined terms of service to strictly adhere to when participating in the program.
On my visit through sites and forums, I daily notice several instances of misuse of Adsense ads. So here a few helpful Google Adsense tips, probably many you already know, and few you might gain by knowing now. These adsense faq are all picked from the Program Policies, Terms and Conditions and FAQ itself and presented in a simplified manner.
1. Never click your own adsense ads or get them clicked for whatever reason. You know this one very well. This is a surefire way to close you Adsense account. Never tell your office associates or friends to click on them. Keep a check if your family or children are busy increasing your income by clicking your ads and indirectly trying to stop your income. Dont even think of offering incentives for clicks, using automated clicking tools, or other deceptive software. Adsense is very smart to detect fraudulent clicks. Check the ads which appear on your pages by the Google Preview tool if required.
2. Never change the Adsense code. There are enough means of adsense optimization & customizations available to change the colour, background or border to suit your needs. Do whatever you want to do outside the code, never fiddle within the ad or the search code. They know it when you do. The search code has more limitations to colour and placement, but you should adhere to the rules. The code may stop working and violates the TOS.
3. Do not place more than 3 ad unit and 1 ad links or 2 adsense search boxes on any web page. Anyway, ads will not appear in those units even if you place more ad units. But this is the limit they set, so it is better to stick to it.
4. Do not run competitive contextual text ad or search services on the same site which offer Google Adsense competition in their field. Never try to create link structures resembling the adsense ads. Never use other competitive search tools on the same pages which have Adsense powered Google search. They do allow affiliate or limited-text links.
5. Do not disclose confidential information about your account like the CTR, CPM and income derived via individual ad units or any other confidential information they may reveal to you. However, you may reveal the total money you make as per recent updates to the TOS.
6. Label headings as “sponsored links” or “advertisements” only. Other labels are not allowed. I have seen many sites label ads with other titles. Don’t make your site a target in a few seconds gaze.
7. Never launch a New Page for clicked ads by default. Adsense ads should open on the same page. You may be using a base target tag to open all links in a new window or frame by default. Correct it now as they do not want new pages opening from clicked ads.
8. One Account suffices for multiple websites. You do not need to create 5 accounts for 5 different websites. One account will do. If you live in the fear that if one account is closed down for violation of TOS, believes me they will close all accounts when they find out. You can keep track of clicks by using channels with real time statistics. They will automatically detect the new site and display relevant ads.
9. Place ads only on Content Pages. Advertisers pay only for content based ads. Content drives relevant ads. Although you might manage some clicks from error, login, registration, “thank you” or welcome pages, parking pages or pop ups, it will get you out of the program.
10. Do not mask ad elements. Alteration of colours and border is a facility to blend or contrast ads as per your site requirements. I have seen many sites where the url part is of the same colour as the background. While blending the ad with your site is a good idea, hiding relevant components of the ads is not allowed. Also do not block the visibility of ads by overlapping images, pop ups, tables etc.
11. Do not send your ads by email. Html formatted emails look well and allow placement of these java script ads. But it is not allowed as per TOS. You do not want impressions registering on their logs from any email even once. They are watching!
12. Keep track of your content. So Adsense is not allowed on several non content pages. But it is also not allowed on several content pages too. Do not add it on web pages with MP3, Video, News Groups, and Image Results. Also exclude any pornographic, hate-related, violent, or illegal content.
13. Do not alter the results after ad clicks or searches - Ensure you are not in any way altering the site which the user reaches to after clicking the ads. Do not frame, minimize, remove, redirect or otherwise inhibit the full and complete display of any Advertiser Page or Search Results Page after the user clicks on any Ad or Search results.
14. Avoid excessive advertising and keyword stuffing - Although the definition of ‘excessive’ is a gray area and is subject to discretion, yet Google adsense with correct placement, focused content and high traffic will get you much more income than other programs, so excessive advertising is not required. Keyword stuffing does target better focused ads, but overdoing it is not required.
15. Ensure you Language is Supported - Adsense supports “Chinese (simplified), Japanese, Danish, Korean, Dutch, Norwegian, English, Polish, Finnish, Portuguese, French, Russian, German, Spanish, Hungarian, Swedish, Italian and Turkish”. In addition, AdSense for search is available in Czech, Slovak, and Traditional Chinese. If your web pages language is not supported, do not use the code on such pages.
16. Only single referral button per product per page - With the launch of the google adsense referral program, you are allowed to put only one referral button for adsense referral, adwords referral, and Firefox with google toolbar referral
17. Do not specify Google ads as your alternate ads. - Several services like Chitika eminimalls allow you to place alternate urls, when a targeted paying ad cannot be displayed. This involved creating an simple html page and putting the ad to be displayed instead. Even Adsense allows an alternate url feature instead of displaying public service ads. But never use Adsense ads as alternate urls.
18. Add Borders between Images and text ads - It was a common policy to increase CTR by placing same number of images as the number of text ads, which falsely gave the impression that the text ads represented an explanation to these images. Insert a border when placing images and text ads in such a manner, to avoid confusing readers to falsely click ads.
Whenever in doubt, it is better to ask for adsense help from the learned staff of Google Adsense. They are very helpful!
