It’s true. I saw this search box option only on one website. The feature will allow you to add a search box to the popup Kontera ads. Once visitor will bring their mouse on top of the highlighted keyword, it will open a small window with matching ad and also the search box option at the bottom of the ad. The selected keyword will be automatically inputed in the search field. After clicking the search button, it will take the visitor to customized Google search result page. Here is the screenshot of this completely new feature.

I looked at the mentioned website’s Kontera ad code but it does not have any additional command for this search feature. I believe this is a premium feature for only special Kontera clients like Tim Carter. This new search box option feature will definitely generate more revenue for Google Adsense publishers.
