Eyetrack studies: Text ads prevail

This eyetrack study should be required reading for any content site publisher or designer. I've excerpted the part about advertising, but you really should read the whole thing.

Close proximity to popular editorial content really helped ads get seen. We noticed that when an ad was separated from editorial matter by either white space or a rule, the ad received fewer fixations than when there was no such barrier. Ads close to top-of-the-page headlines did well. A banner ad above the homepage flag didn't draw as many fixations as an ad that was below the flag and above editorial content.

Text ads were viewed most intently, of all the types we tested. On our test pages, text ads got an average eye duration time of nearly 7 seconds; the best display-type ad got only 1.6 seconds, on average.

Size matters. Bigger ads had a better chance of being seen. Small ads on the right side of homepages typically were seen by only one-third of our testers; the rest never once cast an eye on them. On article pages, "half-page" ads were the most intensely viewed by our test subjects. Yet, they were only seen 38 percent of the time; most people never looked at them. Article ads that got seen the most were ones inset into article text. "Skyscraper" ads (thin verticals running in the left or right column) came in third place.

Also, the study has a whole section on what works best for online advertising and one takeaway is that "ads that blend into look and feel of the page--especially text--draw more eyes."
