Suppose, You have a blog site that is ranking on first page for a couple of KWs. Now, you completely delete the blog and setup a new vBulletin forum there. Will you lose the rankings or will the rankings have no affect? THE REASON FOR THIS QUESTION: I am buying a RANKED site which is a blog. My plan is to delete that blog and start a forum in the same niche. The reason why I am buying this site is because it is already ranked. So instead of starting the forum with a new domain and spend loads of money and months on ranking it, I thought about buying an already ranked domain. Should I go ahead with this? Or is this a stupid idea because rankings will be gone when I delete the blog and install a new vBulletin forum on it?
