Why troubles with domain name in .eu and never in .com ?

Hi me again

Just want to know please a friend of me had domain name in .com, change all to .eu and tell me all stats down horrible ?

So do you think Goo*gle prefer .com and slow to index .eu, or never buy .eu bad bad please ?

thanks a lot

No, what would have happened is that they have lost all the SERPs from the .com and now needs to build them up again on the .eu domain. I would suggest that he puts 301 redirects on the old .com domain to help. This all pass back any link juice from the old site. But you will need to do this for every URL.

To be honest I think he has made a bad move by changing it. he should have just masked the .eu and then promoted that until it out ranked the .com and then done the redirect.
