Our website was hosted at domain X , the webdesigner decided to host the new website at domanin Y
We ranked very wel for specific keywords with domain X. We lost all our rankings with the new domain Y
The webdesigner did not redirect domain X to domain Y !!!
Everything happened 4 weeks ago
What to do ?
My proposal , installing old wbsite again on domain X and redirect domain Y to X
Or is there a better solution to get the rankings back ?
