Hi Robert,
Thank you very much for the detailed reply. The main website is also based in the UK but I'm not sure about the DNS which I will check. If they are on the same DNS, are you saying that redirecting the EMD to the main brand website would contravene Google best practice and we shouldn't do it?
We have a full section for this product range on the main site so it means that there is a viable target for the 301. I just feel like we should be building up this section on the main site and making that better, rather than focusing on the other one, but unfortunately because it ranks so well (I thought Google stopped ranking websites just for the EMD), I need to do something with it!
Thank you for your advise so far. I'm really grateful to you.
Carla
