How to write user url? (with or without a subdomain)?

Question

Web development

While working on a small social site, I ran into a problem. I can’t decide on the final choice of the default user url - either <u>site.name/username</u>, or <u>username.site.name</u>
Depending on what conditions should a decision be made in favor of one or another option?
At the moment, the site works with both options, but perhaps you should decide and make one of them the default, and then promote it further. I would appreciate any thoughts/advice on this.
PS Perhaps I should say that the domain has a ".name" zone - and this may affect the readability of the url (before the zone, or before it, the user's name is written)

Answer 1

Usually a subdomain is preferable, but if it is ".name", then I prefer site.name/vasya.

Answer 2

>site.name/username
and what on the site of other folders will not be?
site.name/about site.name/faq
is the obvious advantage of a subdomain.

Answer 3

If it is supposed to collect various information in the user section - as on the same Habré - then the subdomain is unambiguous.
If it's more of a reference about the user - like, for example, a user profile on some forum - then a subdirectory can be dispensed with.

Answer 4

I would make the opportunities equal, and only then I would somehow use them.
In that VKontakte, it seems like the domain took part in the monetization.
From an SEO point of view, a subdomain is more profitable, sort of.
And the cookies are different, that is, site.name/user1 and site.name/user2 get along with difficulty, and user1.site.name and user2.site.name do not even need to strain.
It is also possible to have different DNS dependent settings for subdomains.
In general, I would map a subdomain to a directory - and it will be visible there :)

Answer 5

site.name/username - more familiar to users, no problem with it. 3-level domain,
the same facebook offers such a scheme
