In Google's Webmaster Tools, under 'Search Traffic', and then 'Links to Your Site', there are 5 domains and 3 of them are old domains of our own and a development domain that are all actually the same site.I have proper 301 redirects on these domains so traffic is all routed to the correct one. But is there any way to tell Google that all of these domains are actually the same? And that they shouldn't be counted as separate links to the site.
The 'Links to Your Site' section of Webmaster Tools all resolve to one domain
