I see you are "Gravedigging" again Ron
It is risky, from an SEO viewpoint, trying to revive these old threads!
IF the revived thread "takes off", and many people put new posts in it, it can be ok.
But, if it does not take off, after you have revived it, here is what happens!
Google sees it as OLD CONTENT
Google is a Vampire, that feeds off Content.
Just as you like fresh food, Google likes FRESH Content, not leftovers!
You try real hard Ron, and I know you Love your Forum.
But it is usually best to start a NEW thread, then it is to revive an old one.
This is why many of the Top Ranked Forums automatically close any thread over 90 days old.
This insures them of a constant supply of fresh new content.
I am subscribed to this thread, and came to give some new roof cleaning related content to this revived thread on PWI.
Chris I do not worry about SEO, thanks for Telling me anyway
