By default RSS would benefit a site that has ever changing content- at least that would be my initial reaction. But did you post in "SEO an Hour a Day"? If not, post there, and I'll watch for comments!Good luck. It is a *lot* of work- I know!

I don't know how much RSS helps with page rank and SEO, but I do know that you must post daily, comment on other blogs that have a higher page rank, and write some articles to get more traffic and backlinks. You should be able to get from a pagerank of 1 to a 3 in 6 weeks if you do these things.

Robert, if you use the right tags, it helps...  and, of course, you need the right blogs..  I think AR is very useful, as is Cre8buzz.com...  Takes a little (lot) of your time, but it's real good marketing for buyers and sellers..  makes you easy to find on the internet, and sellers want to know that before they list with you..
