Duplicate content across multiple domains

[jebernier]

My company has a main domain but also has other domains with the some of the exact same (duplicate) content. The domains were selected for product names.

What should we do to avoid getting penalized in Google for duplicate content?

Thanks-in-Advance,

John

It might help if you could give more details. For example,
Are the domains partially or fully interlinked to each other? Also, Do they share the same server, the same analytics and/or webmaster tools accounts? Also, does each one target different keywords, and if so, how are they ranking now?

The domains were selected for product names.

Were these exact match keyword domain names?

If so, SOME people's sites have been hammered by the Penguin update.

search these forums for Penguin and EMD.

Sorry, here are the details.

1) The domains are not linked.
2) They do share the same server (VPS), same analytics (Google Analytics) and Webmaster Tool account.
3) They each target different keywords although there are some that are the same.

The main domain is www.suncorstainless.com. The other domains that I'm worried about (that share some of the same product pages) are www.stainlesschain.com & www.microstarlight.com.
My boss is also having me build www.stainlessshackles.com & www.stainlessturnbuckles.com to feature some of the same products on the www.suncorstainless.com site.

Not much impact from Panda 3.5 or 3.6 or Penguin, just a very slight traffic drop.

It's still not clear to me how much content is duplicated and how much unique content each site has. Also, do any of the duplicate pages have noindex or canonical metatags? Also, do the pages compete against each other for the same or similar keywords, and what determines which one shows up in the rankings, or do they all show up?
