Welcome to WebmasterWorld Guest from 126.96.36.199
However...in Aol.co.uk, any sites that aren't .co.uk domains, are excluded (even if they are UK hosted!)
Is there any reason for this and is there anyone I could contact?
I don't know whether this decision is from AOL or Google - hard to say. But since AOL is the website hosting the search, I'd probably start there with any complaints. Their "Contact" page offers a feedback form for Search.
This one surprises me. On the surface it seems like a real disservice to their users, especially when Google has the data available.
