Tracking information on a web page?

Question

Notifications

Tell me, please, is there any service or program with which you could receive a letter if the user went to the site? (the status has changed to "Online")
To enter the regular season there and compare, or in another similar way.

Answer 1

I do not understand what you specifically mean (especially about the regular season). Look at Yandex metrics ( metrika.yandex.ru ) and Google analytics ( developers.google.com/analytics/ ) maybe this is what you need.
