Why do some sites connect both Google Analytics and Yandex.Metrica at the same time, and not just one thing?

Answer 1

Google analytics gives more accurate data that Google sees about the site and visitors
Yandex metrics shows more accurate data that Yandex sees about the site and users
In total, they give maximum data about where the user came from, what he did, and most importantly, what queries come from people

Answer 2

Search engines hide from each other the keys by which users come from search engines. In Google Analytics, it is impossible (or possible, but with a large percentage of errors) to see the keys that people came from Yandex search, and vice versa.
Also, each search engine through its services can remove behavioral factors that can be an assessment of the quality of the site. If you launch a site, and in a year put Metrika on it, then with a high degree of probability, if the site is of high quality, it will jump up in the search.

Answer 3

It is difficult to explain someone else's logic, but, for example:
1. It is more convenient to look at different reports there or there
2. No statistics system provides accurate data. By combining data, they want to get a more accurate picture.
3. It's more convenient to watch Analytics, and Yandex.Metrica is needed for Direct.
4. For reliability :)
5. And "what if Yandex and Google then love my site more"
was the first thing that came to mind :)

Answer 4

Google analytics - for promotion in Google, Yandex Metrica - for promotion in Yandex ...
