I'm thinking it's not possible,
but can I add Meta tags to Manufacturer pages?
Add meta tags to Manufacturer pages
Re: Add meta tags to Manufacturer pages
Well I am not 100% sure if it works but you may give it a try. AbleCommerce webpages can render ConLib controls too I believe. For example if you create content page under Administration > Website > Content Pages and place [[ConLib:FeaturedProductsGrid]] in its contents then if you browser that page in browser it will show you the featured products gird. So what I am trying to say is if you you can create a conlib control to list manufacturer details then you can try serving it via a webpage instead of physical page. This means your webpage has area to store meta tags so it will allow you to add meta tags to page through admin side but this also means you can't have manufacturer specific meta tags. In that case if you wanted to have manufacturer specific meta tags then you may need to create manufacturer specific webpage but then I am not sure how you will link them to the main listing page. The only option that comes in mind is to maybe create some static html by hand but that may only work if there are few manufacturers.
