According to the research done by The EyetrackIII research released by The Poynter Institute. A visitor first looksat the logo, then looksfor the headline in the top LEFT of the screen and then scansdown the left of the screen for site navigation before looking around the page.
Here are some snippetsfrom the research site:"The eyesmost often fixated first in the upper left of the page, then hovered in that area before going left to right. Onlyafter perusing the top portion of the page for some time did their eyesexplore further down the page."
"Dominant headlinesmost often draw the eye first upon entering the page -- especiallywhen theyare in the upper left""We found that adsin the top and left portions of a homepage received the most eye fixations." (thisiswhere the Google Adsense adsshould be)
What we need to do ismake sure we place AdSense adsnear the top of the page and some on the left of the page. Thisstrategy isproven to get you more clickswhich result in more money for you.
Thisisalso a sneaky way of making the adsappear asnavigation links. Visitorsclickwithout realising they’re ads. Thiscan be extremely effective indeed.
You should also create the adsso they compliment your website’scolour theme and style. They should fit right in and looknatural. You can change the background colour and text colour of your ads from you AdSense account.
Another AdSense feature you should add to your site is, AdSense for Search. Thisislike an ordinary Google search box but instead of displaying just the ordinary search results, it displaysAdSense adson top of the normal search results. With thisyou can make money whenever someone searchesfrom your site and clickson the results!
