Google took a huge step when they released new AdSense for Search options today, some which no longer show the branded Google logo in the search unit implementation but instead uses the words “Google Search” in the button.
I have never had much luck with AdSense for Search (in fact, I only know a handful of publishers – mostly with similar types of sites – that have had much success with this product from AdSense), and part of the problem was the bulky implementation of the search box that publishers are required to use. I will have to start testing this one again.
Other features added to AdSense for Search inclue the ability to choose the country/territory that will be used for results (ie. using Google.ca or Google.co.uk instead of Google.com, for example)
