They do this like crazy. I too wonder how can they afford to give such things. Their service is only for $15 and they give credits for $100. I am really confused how they maintain their finance....

This is very useful articles for me. A lot of time I searched for free vouchers. Thanks!

Good luck getting banned eventually. Abusing the vouchers is not good. If you think $25 or $100 of google traffic is going to change your life, then that's pretty sad.

96 percent of advertising revenue goes to the top 3 or 4 sites ... the rest goes to the other million sites.

Can anyone say "subscriptions"?

From Google side they are trying to get you hooked and anyone who's signing up at a host obviously has a website so they are the target market for adwords. Plus most people blow threw the credit pretty quickly while they learn the adwords system.
