@OP yeah, now that you mentioned it, it's going to be a heavy manual task to add categorisation, but perhaps find a way to let users add that kind of information.

Sorry, when I said "like Google" I meant like Google map. If you login to google map and allow notification for help settings, you'll get prompted questions about a place you're visiting, like

1. Does this place accept credit cards?
2. Is it handicap friendly, etc.

So for your site, if you could find a way to make it like google map, so users visiting can help update the page like:
- does this place use BitPay?
- does it ship to EU?

I know it's a thankless job but that's the problem I want to try help your site to avoid... because all the listing sites I see started out well until the burden of updating became too much.
