Saidit has like 10

Like 10 what? You didn't finish that sentence. If you meant "like 10 users", visits are basically user sessions:

Similarweb calculates a visit (session) for a website when a visitor accesses one or more pages. Subsequent pageviews are included in the same visit until the user is inactive for more than 30 minutes. If a user becomes active again after 30 minutes, that counts as a new visit. A new session will also start at midnight.

So if a user visits saidit each day in the morning and in the evening (for less than 30 minutes), that alone user would bring ~ 60 visits/month.

Also quoting from my old comment:

These are estimations from their limited data anyway (browser extensions which sell browsing history, DNS data from internet providers and so on), could be wrong 2x-3x in both directions (underestimated/overestimated)
