Welcome to the Q&A Forum

I've been doing some competitive research in Open Site Explorer and many of our competitors have Twitter accounts very similar to ours. Their Twitter pages are usually one of the pages with linking to their website with the most Page Authority.  The incoming links from Twitter are a "no follow" as you would guess. This has been the case for a large number of well ranking sites I have looked at. www.dremed.com also has a Twitter account at:  https://twitter.com/#!/DREmed .  However, Open Site Explorer does not list the Twitter link as an incoming link at all ( or if it does it has no Page Authority ). The Twitter account page seems very similar in nature to other competing Twitter pages.  I'm not sure why it does not ALSO pull a high Page Authority score??? Do you know why this might be? Best, Justin
