Making the most of your website real estate is crucial to the success of your website. The right placement will bring success to your campaign. The wrong placement could mean visitors overlook the most important item on your page.

It’s important to decide your most important call to action and your goals. Once they’re well defined and you move to implementation, this Google Heat Map will give you insight into where visitors eyeballs might be looking.

Since certain locations are more successful than others, Google created this heat map as a guide to their AdWords customers.

The colors fade from dark orange (strongest performance) to light yellow (weakest performance). All other things being equal, ad placements above the fold tend to perform better than those below the fold. Ads placed near rich content and navigational aids usually do well because users are focused on those areas of a page.
