Looking for some advice...

Business has multiple websites, each on different domains (eg .com/.cz/.bz/etc) in different languages for one business location.

I'm seeing multiple Places pages as a result, so I can flag these as duplicates of the main one they use.

From memory best practice is one website per location but....

I can clean up the citations, optimise one site, flag the duplicates and so on. Am I missing something extra because of the situation?

Link all sites to same G Places pg?

Any gotchas to watch for?
