Which is better to use for a multi-word social media address: dots or spaces (underscores)?

Question

Facebook

Hello dear toasters. Help advice.
What is better to use for the address in social networks, if the address consists of several words? Are there any objective criteria or is everything "taste and color"?
There is a certain company with a unique name (let's say LLC "Rotkev"), it has several structural divisions that are engaged in completely different (in terms of the target audience and market segment) business. For example, the production of furniture ("Rotkev Mebel") and the sale of woodworking machines ("Rotkev Instrument").
For pages in social networks (VKontakte, Facebook, Instagram), it is better to use addresses like *.com/rotkev.mebel and *.com/rotkev.instrument or *.com/rotkev_mebel and *.com/rotkev_instrument?
I would be grateful for both objective criteria (search ranking, ease of access, encoding, etc...) and subjective ones (how better it looks offline, how it reads better, how easier it is to type, like this more... ).
Thank you!

Answer 1

Are there any objective criteria or is everything "taste and color"?

doesn't matter according to my data.
I would do 1. Less advertising budget, more traffic, etc. Better 1 live group than 10 with the right url and 3 members. After all, from the point of view of the categorizer of topics in social networks, they will all be in 1 section.
content and its renewal + group members - that's the key to good positions. Don't waste time on nonsense. The url will only play a role for the person. Search engines don't care.

it’s easier to dial a point on a mobile phone
if no one dials you with their hands, then it doesn’t matter
