How to connect Google analytics or Yandex metrics to the site?

Question

Google Analytics

and which one is better?/////////////////////////////////////////

Answer 1

Go to the Analytics or Metrics website, create a counter, copy the counter code, add it to all pages of the site, confirm the installation of the counter in the control panel.
Which is better is up to you.
In my opinion, Google has a more complex and confusing interface.
I would choose Yandex.
And if you run contextual advertising in Yandex or Google, you would put a counter on the service where you are targeting.
