I search for "mycompanywebsite.com" (in quotes) sometimes to check up on who is talking about us. Just did a search today and two of my other websites in completely different industries were in the search results.
These sites do not link to each other. They never have. They don't even have the same IP address. Again - never have. The only things they have in common are:
- matching WhoIs data.
- listed in the same GWT account.
This is not a related sites search, this is a domain search in quotes. So, why would totallydifferentsite.com show up in search results for "mycompanywebsite.com"?
