If everything about two blogs are identical (theme, traffic and contents) but differ only in Google Adsense placement, will their income be the same?

Below are strategies to optimise your adsense placement in order to increase your bottomline.

1. Link Units can be a very good source of Adsense revenue if placed somewhere near the site navigation links.

2. Adsense Ads that do not blend with the background do not perform well.

3.Adsense Ads that are located in the sidebar and below the page fold are rarely visible to the site visitors.

4. Adsense Ads that are located in the sidebar generally do not perform well.

5. The perfect location for the Search Box is in the upper right corner. Additionally, the search results page should use the new Adsense code that allows visitors to search without leaving the site.

6. A 250x250 wide format ad unit mixed with the blog content (near the post title) is usually very effective.

7. Adsense Ads placed at the end of the post is usually effective for lengthy post. Users would typically read the full post and then look for pointers to extra reading.

8. New visitors to a blog are also interested to know more about the blog author so their eyes will automatically search for "About Us" or Profile section of the blog. So it makes sense to place a small 200x200 ad just below the profile section since that space receives lot of attention from new visitors.
