.com & .ie website how to avoid duplicate blog content?

[AdvanceSystems]

We have 2 websites .com & .ie (both are more or less identical except 2 different markets). How can I avoid duplicate blog content as lots of our .com/blog and .ie/blog is the same?

Maybe....

Our main .com blog articles are searchable then on our .ie blog content non searchable? (This way both markets get to view the content but only Google actually searches our .com blog)

Alliteratively I would need to rewrite each article so that is unique

Advise would be appreciated, thank you.

Have you tried to go into Google webmaster tools and geo target the .com for US traffic and geotarget the IE for Ireland?

Hi Irving, Yes GEO Targeting is already set up in Webmaster tools.

Is that enough to put the same content on on both websites?
