I've not used it yet but I plan on trying it pretty soon. This alternative to Google Adsense did come well recommended to me though. It's called www.bidvertiser.com.
If you pay any attention at all to what's going on in the internet marketing world you'll know that a lot of online marketers get treated like shit by Google. I'm one of them. For some reason that I have no idea of, Google deactivated my Google AdSense account. And apparently it's a common problem.
Google is so fucking BIG that they don't even feel like they need to explain to probably thousands of people why their AdSense accounts have been shut down....but, I digress.
It is possible (and a lot of people are silently doing it) to set up blogs that are automatically populated with content. And you can monitize those blogs with pretty much any form of monitization you want. AdSense is a logical choice but since so many people can't get AdSense accounts, there's been several legitimate and more even-handed alternitives come onto the scene.
www.Bidvertiser.com is one of them. If you have a blog and you're not monitizing it, you're probably leaving some money on the table.
