Jul 24, 2010 by Shivendu Madhava

AdSense for content is the bread and butter of many of AdSense publishers, and we often receive requests to recommend strategies to improve AdSense performance on publisher sites. While we refer to this as ‘optimization’, we understand that this term can make the process sound more difficult than it really is.

This time, we’re recommending you think big – big ad units, that is:

Publishers often ask what the best ad sizes are to include in their site’s design, and we always point them to these three:

300×250 medium rectangle
728×90 leaderboard
160×600 skyscraper

These ad units have proven in the past to deliver better results for both publishers and advertisers. Advertisers favour these formats, and if you’ve receiving all ad types, you’ll find that advertisers will specifically target your sites more often. If you position your ad units well, users will be more likely to see these ad formats and find an ad that they’re interested in.

When you’re considering how to design your site, testing has shown that displaying at least one of these ad formats on your page can increase your AdSense earnings potential. So remember, sometimes bigger is better!
