Publishers frequently ask for new ways to increase the relevancy of the AdSense ads shown on their sites. Today, we're pleased to announce two features to help you display highly targeted ads to your users in new and exciting ways.

AdSense for Search Ads Only

You may remember that last year, we introduced the Custom Search element to help you easily bring Google search results and ads to your site. More recently, we introduced data rendering to give you even more control over how the results are shown to your users.

We understand that some of you may have your own, non-Google search results that you'd like to monetize. In the past, this typically meant that you weren't able to use AdSense for search ads. Now, with AdSense for search ads only, publishers can now include AdSense for search ads on their pages and pair them with their own, homegrown search results.

By adding just a few lines of JavaScript to your page, you can display AdSense for search ads above, beside, or below your own search results. You can pick the size, shape and number of ads displayed in each block, and you can even adjust the style of the ads to better fit the look and feel of your site. For instance, check out how seamlessly MerchantCircle has integrated AdSense for search ads only above and next to their search results.

AdSense for Ajax

Whether your site offers your own search results or not, if you have dynamic content, you may be interested in delivering your AdSense for content ads with AdSense for Ajax. With traditional AdSense for content, ads refresh only when a page is reloaded. This works great -- but isn't optimal when your site relies heavily on Ajax, which allows visitors to navigate a lot of content without actually leaving a single page. Also, sites that generate a lot of dynamic content that isn't crawlable are difficult to target accurately.

Here's where AdSense for Ajax comes in. With AdSense for Ajax, your AdSense for content ads will refresh whenever there's a context change - regardless of whether the page reloads or not. Travel site has taken advantage of this by showing relevant ads based on the selected tab. Try clicking on the "Hotels" tab. The page doesn't reload, yet the Ads by Google have refreshed to show ads more relevant to hotels than flights.

In addition to the ads refreshing, you might wonder why the subject of the ads changed since the crawlable content on the page didn't change much when the tab changed. The second benefit of AdSense for Ajax is that it allows you to provide hints about your site's uncrawlable content with each refresh.

Both of these AdSense features can be easily added to most sites by just copying and pasting a few lines of JavaScript code, which will help you show highly relevant ads to your visitors.
