- Always select "text/Image ads" option when you create an ad unit.This might increase your revenue.
- Always keep minimum one ad in the first half of your site/blog.Meaning your page visitor should see the ad without scrolling till the end of the page.
- NEVER EVER CLICK ON YOUR OWN ADS.Once Google disable your account,you will never be able to get back to adsense program.
- Don't keep too many ads on the same page.Google gives you a limit for this 3 ad units,3 link units and 2 search boxes in one page.We suggest you not to use the maximum limit,because too many ads will make your web page/blog look cluttered.
- Try to match your ad units color theme with your web page's color theme.BUT DON'T CONFUSE THE VISITOR by placing the ad units between some links.
- Don't use 'CLICK HERE' Buttons or a text near google ad units.
- Don't try to edit ad unit's HTML scripts.
NOTE: For some countries like India and China Google demands the website/blog has to be 6 months old.But in some cases if you have enough content they approves your site.
