We are starting to get into net (pod)casting and web-based business enterprises and need to promote our websites, netcasts, blogs, etc.. We are researching and discovering lots of good ways to self-promote, but we also want to enlist the help of a good SEO company with a proven track record to augment our own efforts. Given that there are hundreds of companies on the net clamoring for our business, how do we find one that will get the job done for us? Is there a forum of some kind where we can find some relevant, informed input on this?
