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 of you already know, and few might gain by knowing now. These facts 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. Don't 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 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 units and 3 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 tools on the same pages which have Adsense powered Google search. They do allow affiliate or limited-text links. Update: Google has allowed you to run contextual advertising like Yahoo ads, Chitika etc provided the ads do not resemble Adsense ads.

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 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 fears that if one account is closed down for violation of TOS, believe 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.
