Duplicate products across numerous catalogues on an eCommerce site

[TTS_Group]

We run a site that contains many catalogues aimed at different markets. Products can appear in one or more catalogues. The product copy etc will be on the whole similar maybe even identical across those catalogues. So I'm assuming these will be flagged as duplicates? If so is there a way to fix this other than completely re-writing the copy for each catalogue?

You could choose a single version of the product page to act as the main version and implement rel=canonical tags.

The downside to this is that (in theory) only that version of the page will rank.

If it's really important to have the different page variants rank for different search terms then you'll have to start rewriting the product copy.

Thank you Ben. Strangely we are just doing this on our paginated range pages as they currently show as duplicates at present too.
