If you earn revenue from your site by using Google Adsense for Search, you will like the new ability to blend the search results within your site. Previously the Google Adsense for search results opened on a full page which had no relation to your site hosting or website design, which did not blend well with your site.
You could customize the link and text colors, add your site logo, colour up the lines and decide if the search results open on the same page or on a new page. Now when you customize your Adsense search code, you find a new option to click the radio button marked Open results within my own site.
By adding an additional set of search results code to your page, you can display Google search results framed within your own site. This new option will help you blend AdSense for search into your site even further. Try it out.
