Welcome to the Q&A Forum

I was just wondering if a page has been booted into the supplemental index for being a duplicate for example (or for any other reason), does this page pass link juice or not?

I don't think that the H1 makes a massive amount of difference on its own. However, I think that search engines do actively look for a semantic structure. In other words, you should use H1 and structure the content along with H2 and H3, and a couple of image ALTs in there for good measure.

To be honest, your site has a few other SEO issues that I would look at first like lack of textual content and webmastery for example.

I've got a client with a large e-commerce site with a  .com domain and they want to start targeting France. Other than building another site in Frence with a .fr domain, what would be the best course of action?

I know that the obvious option would be to build a separate French site with a .fr domain but is there another more cost effective way?

I tried doing a search for one of their key-phrases using the Google Global app (Google.fr) and they are ranking in pretty much the same position as for Google.co.uk.

Your thoughts on this would be greatly appreciated.
