Welcome to the Q&A Forum

It doesn't necessarily matter if the auto generated content is unique or not - Panda was intended to penalize low quality content (such as auto generated content), not just duplicate content. Even if you were able to figure out a way to auto generate content  that didn't get penalized, there's a good chance you'll get penalized in a future update.

Don't hide the content - if you have not done it, use microformats to "dress up" your content - this should include hproduct and hreview markups.

Thanks Irving for understanding it. Here are the links for both sites http://www.printsasia.com http://www.printsasia.co.uk

And the sitemap for good measure. And preferably hardcode any internal links that you can to point to the new default.

Yes as we are an eCommerce site, we have login and cart pages as secure. So as per the responses received so far, we should not worry about it. -The canonical element is already there for protection Adding no index or restricting through robots can be added precaution Thanks everyone for the reply!

Hi Cyril, I've not seen any specific case studies or statements that figure out how much replication is considered duplication, although I'd be as interested in you in this information if anyone out there knows of some? Personally, I have been working on a 50% minimum basis (e.g at least 50% of the pages written content should be unique), and it's been working well for me. You might get away with less. In regards to making sites an authority within their specific countries, whilst using duplicate content and the canonical tag, it's all down to links. Even though you're telling Google that this isn't the original source of the content, it's still possible to build up authority on the domain by acquiring links from strong sites that share the TLD. But again, without unique content you're not going to see the full strength of these links. David

Absolutely. We have seen nothing but positives when using the hreflang tag. Of course, make sure you use it appropriately and don't accidentally tag a page that doesn't have a sibling on the other ccTLDs
