If you’re a blogger, you’re probably familiar with Chitika.
If you aren’t familiar with them, they’re very similar to Google’s popular Adsense contextual ad service.
In fact, Chitika is where many bloggers who were turned down for admission to the Adsense program (or got booted from it) ended up turning to earn revenue from their blogs.
Although Chitika never really gained a lot of traction against the ultra-popular Adsense, they did serve as a vital source of income for quite a few bloggers who were unable to take advantage of the Adsense program for whatever reason.
If you currently have Chitika ads running on your blog(s), I have some bad news for you: The service has been shut down, effective immediately.
