SEO Tools - AdSense Preview
Google AdSense™ automatically delivers ads targeted to your website content. The more targeted your pages are for one or two topics, the better the ads are likely to be. This free preview utility will give you a sense of which ads would be placed on a given page.
The ads shown on your pages will change over time as your content changes or the inventory of Google ads changes. You should check back here often to review which ads will be shown when you're working on updating your pages.
