Is there a service for summary statistics of attendance and / or activity of IT-oriented resources on the Internet?

Question

Communities

I decided to collect a selection of information resources in case of a Google ban, and therefore the question is:

Are there any services on the Internet for collecting and then viewing statistics of attendance and / or activity for resources on the Internet dedicated to IT? If so, which ones? What is the price/terms of use?

I mean, large resources with a large audience.

• "Large resources" here means such that their non-overlapping audience is at least 20% of the total professional audience of this topic. (For example, social media about technology, like the same habr)
  
• [UPD] To rephrase soberly: statistics should be based on such a sample of Internet resources that every fifth worker in our industry uses at least one of them on a regular basis.
  

Answer 1

Attendance statistics are usually closed, but there is a Similarweb resource that provides information about attendance of relatively large resources on the Internet.
