ReviewMe, the pay for review service initially stated that they were going to be updating site information on a monthly basis. As many people might have noticed they didn’t quite manage that, in fact it has been over 2 months since my first, and only review for them, of Aaron’s Search Engine Glossary. (I still have to make an affiliate site from his content).
As I stated in the comments in that post, I also contacted Google directly but I asked multiple questions. I had to use the email route not having a direct line to decision makers at Google, but Google have been fairly prompt in replying to my questions.
I talk about how you can use UTW quite a bit from an SEO perspective, but it can also help with monetization. If you have keywords, you can use them for all kinds of things.
