Keyword targeting can sometimes feel like a guessing game. Potential customers are performing hundreds of millions of searches on Google, most of which you don't even know about. With so many searches, you have to guess which ones might be relevant for each of your landing pages, and hope you find the right audience for your AdWords campaigns. That's where the Search-based Keyword Tool (beta) comes in. With this new tool you can get a better sense of what your potential customers are searching for and which keywords you should advertise on.

Here's the scoop: you know that the Google search engine starts with searches conducted by users and helps them find relevant pages. But for keyword targeting, what you want is a tool that goes in the opposite direction by starting with your pages and identifying keywords that potential customers are searching on to find your products or services. The Search-based Keyword Tool does exactly this, leveraging search query data relevant to your website's content. In other words, this new tool gives you keywords that are highly relevant to your site but are not part of your AdWords campaigns. This helps you take advantage of missed opportunities.

The tool is also useful if you don't currently advertise on AdWords. For example, a shoe store could discover which footwear styles users are searching for, or a digital camera blog could decide which cameras to review by looking at which camera models attract the most queries.

The Search-based Keyword Tool is now available to all advertisers in the US and UK. We'll be expanding to additional languages and more countries in the near future. We'll also continue to develop the tool based on your feedback. Try it out at, and let us know what you think.
