It depends on the kind of shops. E.g vehicle related shops, typically have 1 or only a few brands. The listof brands fixed for longer periods. I think the same is true for some fashion outlets where you can only find a collection from a limited number of brand.
I wouldn't start adding brands to all products you find in a supermarket, garden centre, DIY etc. But for those shops the categories of products can important, or at least more important than the actual brands. regards m On Sun, Mar 6, 2016 at 9:47 AM, Ralph Aytoun <ralph.ayt...@ntlworld.com> wrote: > My personal opinion is that this is getting totally out of hand. > Shops pay a lot of money to advertise their wares and you are stepping in > and trying to do commercial marketing for free. > Not only that but who is going to maintain this information?
