How To Detect Primary Site With Duplicate Domains?

[brettgus]

I'm working with some backlink data, and I've run into different domains that host the same exact content on the same IP. They're not redirecting to each other, just looks like they're hosting the same content on differnet virtual hostnames. One example is:

• borealcanada.ca
• borealcanada.com
• borealcanada.org
• www.borealcanada.ca
• www.borealcanada.com
• www.borealcanada.org
• www.borealecanada.ca

I'm trying to consolidate this data and choose which is the primary domain. In this example, it appears www.borealcanada.ca has a high number of indexed pages and also ranks first for "boreal canada". However, I'm trying to think of a metric I can use to definitively/systematically handle this (using SEO Tools or something like it).

Anyone have ideas on which metric might help me determine this for a large number of sites?

Go to any site that they may be jointly ling to and evaluate the strength of each of the links pointing to the site.  If you see one of the domains being dominant in their back link data, I'd chose that one.

I know this is not exactly the answer to your question, but I would also do some additional research around keyword ranking.   Look at what content is duplicated on the sites then search the title tag or the opening sentence.  See what site shows up across a group of pages (be sure you are logged out etc).   You should see a trend of one site that shows up more often than others.   Use that as one of the "votes" in addition to things like PA in OSE for those pages and also the amount of traffic that the pages are getting in comparison to one another (again, comparing the results for duplicate pages across sites).  You could put all this into a spreadsheet and it will start to point you in the right direction.

At a domain level, you can put 5 domains into OSE at any one time and get a quick analysis.  That shows the same as what you mention that the lead is www.borealcanada.ca

Seems like you just need to 301 all the other domains page to page to that one.
