If I install the same metric counter on several sites, will it work?

Question

Yandex.Metrica

If I install the same metric counter code on several sites, will it work?
(at the same time, only one domain will be indicated in the metric itself)

Answer 1

Yes, in principle, it should work and collect statistics. In statistics on visited pages, there should even be a division into two sites.

Answer 2

Will work. In the settings, you can specify in the additional domains those domains where you will put the Metrica counter. If only one domain is specified in the settings, then do not check the box "Accept data only from the specified domains", then everything will work and all sites will be displayed in Yandex.Metrica reports.
