What's Next
In general, publishers who implement AdSense for search on their sites earn much less from it than AdSense for content. If you think about it, this makes perfect sense: Visitors are more likely to use a page's search box for site-specific searching, not for general Web searching, and to click on ads on the content pages they find because of the search, not on the ads on the results pages. For publishers with no current search capabilities, however, adding AdSense for search is a simple way to provide a useful service and perhaps even make a bit of money from it.
In the next article in this series we'll return to AdSense for content and discuss keyword optimization techniques for targeting ads and getting higher search engine rankings.
