On another site, a poster wrote "The issue is probably because the IP for your site will have changed when you moved providers, and my guess is Google is marking your side down because of this. The good news is that Google appears to have a time limit (of about a year) when things should return to normal"
Now, I have only switched a very small site for a friend who is a niche supplier from one web host to another. For some keywords, he is page one in Google - but then the niche nature of his business probably helps that.
However, I want to switch the company web site from one host to another, because I will get better technical support and better value for money. But obviously I don't want to disappear off the radar with Google. Has anybody here experienced a dip in ranking with Google after changing site host?
