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 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 search 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.For complete this article you can read in here .
