Google seems to be recognising subdomains with same content.

Same backlinks listed.

Hi all. I have a site example.com. Now example.com has a static and a dynamic version. (static.example.com and dynamic.example.com) Now with the exception of the format of the links and file names both sites are exactly the same. When I used to look at backlinks for dynamic.example.com it would come up with links that linked to a product under that domain. It now comes up with everything linked to any domain at example.com. Is this a change in the way backilinks are done (ie. it only checks the root domain example.com) or has Google realised they are the same site and so shows the links to both of them?

I think its that Google realised they are the same site and so shows the links to both of them.

Well it only took 2 years. Still it is somewhat odd.

Imho G recently worked on their dupe content filter and made some improvements. That's probably why they start showing up as one just recently.

Any effect to pagerank?

No change to pagerank.

GoogleGuy confirmed several months ago, in this very forum, that they run a process every few months to recognise different URLs that are really the exact same page, and equalise the reported PR for all of them.
