I recently did a
paid review of a product as a post as well in SEOR's blog, and mentioned the fact that it was a paid review right off the bat. Personally I'll review most any product etc that I am asked to, however, I won't just rubber stamp a good review. In fact, I go into most things more than a bit skeptical so a good review is going to either A) be well earned or B) cost you a LOT more money than you're willing to pay for it
.
Personally, I think this method of advertising is brilliant and I will be using it shortly. From a blog owner's perspective, it gives you a chance to earn more in one post than you might in an entire day from adsense or YPN earnings.
Now, it probably does give the SE's a hard time but hey, that's their job right?
