Inside AdSense: Your optimization checklist, Part 1

Inside AdSense: Your optimization checklist, Part 1: With a fresh start to the year, now is a great time to review your AdSense strategy to ensure you’re making the most out of your ads. With that in mind, we’re kicking off a two-part optimization checklist series to help you increase your earning potential. In this first post, we’ll review some oldie-but-goodie tips; take a look, check off the items that you’ve already covered, and see if there’s anything you may have missed. 

1. Increase ad coverage: Placing additional ad units on your site can have a big impact on your earnings. You can put up to three standard AdSense for content ad units (note only one 300x600), three link units and two AdSense for search boxes on each page of your site. Sometimes publishers find it difficult to decide whether an additional ad unit makes sense for their site. Watch this short video to help you make sure you're following best practices, as outlined on Google’s Webmaster Guidelines, when placing new ad units on your site. As always, it’s important to consider the amount of ads in relation to the quality content on your site. 
2. Use recommended ad sizes: As a rule of thumb, wider ad sizes tend to outperform their taller counterparts, due to their reader-friendly format. If positioned well, wide ad sizes can increase your earnings significantly. The sizes we've found to be the most effective are the 728X90 Leaderboard, the 336x280 Large Rectangle, the 300x250 Medium Rectangle, and the 160x600 Wide Skyscraper. Keep in mind that while these ad sizes typically perform well, you should use the size that best complements your pages.
