How to find out the statistics of someone else's site by month?

Question

Google

Seo offices call and say, guys, we see that your attendance is growing from month to month.
Then I had a question, how is it possible to observe other people's sites, their increase in attendance and decline, not manually, but every day to go and see the attendance or look at the months for years?

Answer 1

Well, if your site is large and popular, they can rate your visitor by Alexa's rating.
If your site is small and little known, it is almost certainly a salesperson's place to flatter, strike up a conversation in this way and sell your services during it.

Answer 2

If access is open in Metrika or LiveInternet, you can watch.
MegaIndex, SimilarWeb.
For bourgeois SemRush.
The numbers are naturally inaccurate in showing these services, but you can roughly estimate traffic, keys, positions, etc.

Answer 3

similarweb is enough
, but, given that you don’t know about it, it “grows”, most likely from two to two hundred uniques ))
