If you’re an AdSense publisher looking for advice to improve your earnings, Google has a tip for you: Bigger is better. Google recommend using larger ad blocks on your site because they have been proven to deliver the best results.

Here is a simple video from Google explaining this:

These larger ad units typically perform better because advertisers tend to favor these formats and they’re more obvious to users visiting your site. Google have identified the following three ad sizes as having the best performance:

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

If you’re using AdSense on your site, I would recommend trying to include at least one of the above formats on your page. Careful placements next to or around your content is the best way to get users clicking!
