anybody have any experience with adsense search boxes? Do they bring down overall ctr or ecpn on your sites?
I've used the AdSense search box for many months now, and while it doesn't bring in a lot of revenue, it's nothing to sneeze at. However, I don't use the Search box you can create from the AdSense control panel area -- I use the Google Custom Search, which allows you to provide search results within the look and feel of your own site (and which, in my opinion, doesn't make it look like users are leaving your site when they do a search). Check it out here: http://www.google.com/coop/cse/ You can link it up with your AdSense code, so that ads will be displayed on search results just like AdSense for Search.
