Recently Google announced two cool new optimization options which would be of great value to publishers. These features are Adsense for search ads and Adsense for Ajax. I think both have their uasability and if used well they can bring in more revenue.
AdSense for Search Ads Only
Now in addition to custom search ads option there is another option for monetizing the search ads. You can now monetize your own, non-Google search results. 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.
AdSense for Ajax
Other option is content ads with AdSense for Ajax. With traditional AdSense for content, ads refresh only when a page is reloaded. However Ajaxallows visitors to navigate a lot of content without actually leaving a single page. You must have come across tabbed interfaces where you can browse different tabbed sections without reloading the page.
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.
I am amore interested in the former one as I do not use Ajax.
If you use please let us know your feedback for sure.
