I think that adsense search box is a very good source of income for bloggers. Most blogger blogs do not have search function and instead have archives. When users are looking for content, they need some navigation strategy. Otherwise they use the search function. Therefore, I think adsense for search is a great tool for bloggers.

What are your views about this?

Oh.. I did not get this idea. This sounds very logical. There is no other way to search through any blog be it either blogger or writingup. We needed to using 'next' buttons. I used to get irritated and used to leave the blog immediately even when the blog was of some use. Now the blogs having search box can benefit very much.
