I've got a client's company site with decent PageRank, backlinks and search engine rankings.
The client wants to change their company name and therefore URL. I will set up a redirect between the old site and the new. But I was wondering, is there a way to tell Google that they are moving while retaining all the rankings?
It is the same people, services, office building, same everything, just rebranded under a different name and URL.
Additionally if there is a way to do this, how does Google handle you buying expired domains and just pointing them onto your site? Could I buy several PageRank 3 domains all relating to the same sector and point them at my site or would Google catch on to this?
