Matt says if a domain changes hands, Google resets the links vale to zero/near zero.
Quote from John Andrews who is live blogging from live domain roundtable, but I got to ask Mr Cutts how do you know?
- When Whois record is changed
- When hosting or IP is changed
- Some monumental onpage change
Now all three have the potential to be indicators of change but each could also be innocent, changing whois info is quite common including ownership. I recently changed several domains which were marked as an individual to my companies name, the owner did not change as they had been company run from the site. People change hosting all the time, and people scrap their sites and start again (though this would cause potential inbound link issues) so neither of these seem likely. Which leads back to number 1 the Whois record incorporated into the algos? Other then for look up searches that is?
Update – I wasn’t alone spotting this Patrick also noticed and asks his own questions on if its fair to penalise sites for changing owners
Update 2: From the comments, the reference of changing owners could be related simply to expired domains. In which case the comment might considered to make more sense, maybe
Has anyone noticed activity to indicate this is true? Not that I don’t trust you Matt just hey it seems a little odd!
