The majority of people I know does not have a Facebook account. They are most likely never finding the business in first place.

I don't think it's a 1% problem. At least not here in Europe.

I just checked, by official numbers 60% of Switzerland uses Facebook regularly. Obviously not accounted for multi accounts and bots, ... Who in their right mindset would target only 60% of people for a proper business? Mainly woman, mainly 50+. Which bank invests in a business plan like this?

I think you would be suprised just how many people are no longer active on social media anymore. I am honestly not sure who still uses Facebook regularly.

I don't disagree.

The only Meta app I use on a regular basis is Whatsapp.

But that doesn't negate the fact that maintaining a Facebook page is something a non tech person can do for free on their own reasonably well.

So could they use any other obscure platform. Ex. Restaurants are prone for not having their own proper/updated websites, but there are thousands of website builders just for that. There is zero reason to use Facebook as business website if your target is to make business with anyone else than Facebook users.

Your average person is incredibly technologically illiterate. Even something as simple as learning a new basic, streamlined CMS is going to be a lot. Using Facebook, which they mostly already know how to use is much easier.
