Welcome to the Q&A Forum

Our site checks whether visitors are resident in the same country or live abroad. If it recognises that the visitor comes from abroad, the content is made more appropriate for them. Basically, instead of encouraging the visitor to come and visit a showroom, it tells them that we export worldwide. It does this by IP checking. So far so good! But I noticed that if I look at cached pages in Google's results, that the cached pages are all export pages. I've also used Google Webmaster Tools (Search Console) and rendered pages as Google - and they also render export pages. Does anybody have a solution to this?
Is it a problem?
Can Google see the properly (local - as in UK) version of the site?

For the purpose of simplicity, we have 5 main categories in the site - let's call them A, B, C, D, E. Each of these categories have sub-category pages e.g. A1, A2, A3. The main area of the site consists of these category and sub-category pages. But as each product comes in different woods, it's useful for customers to see all the product that come in a particular wood, e.g. walnut. So many years ago we created 'woods' pages. These pages replicate the categories & sub-categories but only show what is available in that particular wood. And of course - they're optimised much better for that wood. All well and good, until recently, these specialist page seem to have dropped through the floor in Google. Could be temporary, I don't know, and it's only a fortnight - but I'm worried. Now, because the site is dynamic, we could do things differently. We could still have landing pages for each wood, but of spinning off to their own optimised specific wood sub-category page, they could instead link to the primary sub-category page with a ?search filter in the URL. This way, the customer is still getting to see what they want. Which is better? One page per sub-category? Dynamically filtered by search. Or lots of specific sub-category pages? I guess at the heart of this question is? Does having lots of specific sub-category pages lead to a large overlap of duplicate content, and is it better keeping that authority juice on a single page? Even if the URL changes (with a query in the URL) to enable whatever filtering we need to do.
