Hi,

I recently find a site that sell a software that helps you create Doorways but in a very advance way. It is creating the doorway pages on the server directly, but what got my attention is that the doorway pages are loading every time different content using random RSS Feeds that are targeted to your keywords. So as it is saying that site is that the Search engine robot will find fresh content at your doorway pages at each visit and that way it doesn't ban your doorway pages as it looks like human hand made forever. It also say there that they give Life time money back Guarranty. Does any body knows or have try this software? I think of buying it but a little advice will be usefull. The software name is TrafficBoosterPro and the site link is http://TrafficBoosterPro.com

Regards

Do RSS improve my Pagerank?

PR does not depend on anything but only on backlinks.

I use RSS feeds to be created everyday automatically when I have dynamic content. This helps the spider reference the information that is new and keeps the site updating which Google prefers. It is a great index for google to rate your site and select words that searches will use. To my knowledge this isn't bad practise as long as you don't abuse this method.
Creating these yourself will save a lot of money.
There is plenty of information on the Web to create static ones if you wish to try this first.
