Anyone know a search operator that tells you how many unique domains point to your site as opposed to links (i.e. link:yoursite.com). Thanks. - PT
It's possible a tool exists, what I meant was Google doesn't have an operator for this. Such a tool would be possible, but would use a tremendous amount of resources.
You could probably get a pretty good idea (guess) by looking at the referring site/URL report in your logs. Probably not what you are looking for, but it could give you a hint.
