Chitika, unlike Google AdSense, is a non-contextual advertising network that may also serve local ads to your website’s visitors.
The USP of Chitika are the search-targeted ads that show up when someone lands on your site via a search engine. Chitika extracts the search query from the referring URL and serves matching ads. This will however not work for visitors that are using the secure (https) version of Google as it no longer passes the referral parameters to the visited site.
Chitika also offers mobile targeted ads that are served to visitors using iOS or Android devices. There new Hover format puts ads in the bottom right corners that will become visible as users scroll down a page – much like the fly-out menus in The New York Times stories.
