Google Adsense Tips, Tricks, and Secrets - Part 3

Google has also has published a list of the highest performing ad sizes:

• 336×280 large rectangle
• 300×250 inline rectangle
• 160×600 wide skyscraper

From the sites that I run, I do really well with the 336 rectangle and 160 skyscraper. My next best performing ad size is the 728 leaderboard, I don’t really use the 300 inline rectangle too often. So really it depends on how well you integrate these into your site. Placement can have a dramatic effect on performance. TIP: When working on a new site or new layout you may want to give each location it’s own channel for a little while until you understand the users behavior.

Another ‘trick’ that can increase your CTR is by blending your adsense into your body copy. For example if your body copy is black, remove the adsense border and make the title, text, and URL black.TIP: Try changing all of your page hyperlinks to a high contrast color (like dark red or a bold blue) then change the adsense title to the same color.

The one area where I’ve found blended ads don’t perform as well is forums, especially ones with a high volume of repeat members. Regular visitors develop banner blindness pretty quickly. One ‘trick’ to keep the ads from being ignored is to randomize the color and even the placement. As with any of the decisions about location, placement and color it’s a trade off. How much do you emphasize the ads without annoying your visitors. Remember it’s better to have a 1% CTR with 500 regular visitors as opposed to a 5% CTR with 50 visitors. TIP: For forums try placing the adsense ads directly above or below the the first forum thread.

Using Images

One of the latest ’secrets’ to make the rounds is using images placed directly above or below an adsense leaderboard. This has been used for a while but came out in a digital point forum thread where a member talked about quadrupling their CTR. Basically you set up the adsense code in a table with four images that line up directly with the ads. Whether or not this is deceptive is fuzzy and very subjective. Obviously four blinking arrows would be ‘enticing people to click’ and be against the adsense TOS. However placing pictures of 4 laptops over laptops ads isn’t, so use your best judgment here and look at it from the advertiser or Google’s perspective. If you have a question as to your implementation being ‘over the line’ write to adsense and ask them to take a look.

As far as using the images, I’ve done it and can tell you it definitely works. You get the best results when the images ‘complete the story the ads are telling’. For example if you have ads about apple pies, use pictures of freshly baked apple pies, instead of granny smith, Macintosh, pink lady, and braeburn apples. TIP: Don’t limit yourself to using images only on that size ad unit, it works just as well with the other sizes, like the 336 rectangle.
