If you are in doubt if your site will match the criteria of AdSense or just want to play around with a little bit, then try this free AdSense checking web tool, which is actually provided by Google directly and allows you to peek at which Google AdWords may be displayed on your site.

Brief Description of the AdSense Web Tool

The AdSense Web Tool is useful for discovering what Google AdWords will be displayed on your site. Google wants to display "relevant, text-based, un-obtrusive Google AdWords ads" on your web pages.

More quotes from the FAQ on how Google describes the process of selecting AdWords to display on your website:

"Simply put, we provide you with AdSense HTML ad code to place on the web pages on which you want to display AdWords ads. Then, we take care of the rest by leveraging award-winning and proprietary Google search and page-ranking technologies to deliver relevant AdWords ads to those content pages.

"We go beyond simple keyword matching to understand the context and content of web pages. Based on a sophisticated algorithm that includes such factors as keyword analysis, word frequency, font size, and the overall link structure of the web, we know what a page is about, and can precisely match Google ads to each page."

That means baby-dool sites won?t get PC hardware ads displayed ? sounds logical.

How Does Google Know What AdWords to Display?

If Google has spidered your site, then it knows about the topics of your site., which enables Google to pick appropriate AdWords to display.

However, if Google has not yet spidered your site, then Google uses your URL to first decide which Google AdWords to display.

That means that your URL is very important. Selecting the wrong domain name or file names

can significantly impact your income from AdSense.
