Is anyone familiar with www.payperclickcompass.com. The site looks like it is current, but I see so many comparison websites that it can be hard to trust some of them (yes, I know that they get paid if you sign-up).

the fact that all their internal links are broken and the home page has little useful info about the quality of the various services makes it a site which does not add much value to the web

I don't find any broken links. I kind of don't the companies that just say recommend because the say that they recommend all of them.
This site does seem a little harsh towards BrainFox. I'm not familiar with BrainFox, but I can't imagine that they're that bad. :confused:

generally best to start with adwords and overture and then maybe try some of the smaller ones after you find terms and campaigns which work on at least one of those two.
