Today while browsing about Adsense I learned a lot of things about Adsense. I really doesn't know about hose things earlier.

1. Use all 3 banners which Google allow to put on a single page.
2. Place at least one banner in the middle of your blog / page.
3. Remember that homepage generates 30% of your clicks.
4. To increase clickable field it is better to use banners instead of text links. Blog readers click banners more often than visitors of a regular website.
5. Background of your ad should be the same as background of the place where unit located.
6. Border color should match unit color. Simply, border should be invisible.
7. Link color in the ad unit must be the same like color of your regular links.
8. Use AdSense banners on all available pages. Don’t leave 404, archives, search results… without AdSense code.
9. Yes! You can use plugins and software which will help you to insert AdSense banner inside blog post, content, between comments etc.
10. Don’t put search box if your traffic is small. Search box is effective on old blogs with thousands posts.
11. Don’t use link unit.
12. YouTube - AdSense program is a waist… never gives any clicks!
13. Avoid AdSense referral buttons unless your blog related to SEO or web marketing.
14. Create channel for each ad unit to track your clicks.
15. Filter ads which you belive doesn’t match your content, it is available on Competitive Ad Filter page.
