How to make pagespeed and yandex.metrika friends?

Question

Yandex.Metrica

Good afternoon. I know it's a hackneyed topic, but I didn't come up with anything useful.
When installing yandex.metrika ps lowers points for mob. from 96 to 68.
Using a crutch

var loadYa= false;
window.addEventListener('scroll', () => {  
  if (loadYa=== false) {
    loadYa= true;  
    setTimeout(() => { /* metrika */ }, 1000)
  }
});
k.async=1 установлен

But, the business is afraid of the incompleteness of the metric data.
Tell me how to optimize the loading of the metric.

Answer 1

For robots, in general, you need to hide all metrics from the site. So the statistics will be correct.
We are using jenssegers/agent , which is there $agent->isRobot()to weed out most robots.
You need to understand that the mechanism for measuring the speed in PageSpeed ​​is also not ideal. When the PageSpeed ​​robot visits the site to measure the speed, it opens a clean session (as incognito) but in the browsers of real users, the metric will already be in the browser cache when they open your site.

Answer 2

Let your business choose between parrots and incomplete data paranoia.

Answer 3

Yandex Metrica cannot be optimized without data loss. Load it asynchronously, this is the best solution, but you should understand that you will not see people "refuseniks".

Answer 4

If you still have the "old" Yandex.Metrika code, try using it.
According to PageSpeed, watch.js loads noticeably faster than tag.js :

Answer 5

A dumb solution to deceive the client is to block access to a part of the code for pagespeed.
type

<?php if (!isset($_SERVER['HTTP_USER_AGENT']) || stripos($_SERVER['HTTP_USER_AGENT'], 'Chrome-Lighthouse') === false): ?>

Answer 6

If WordPress :) then as a rule I drive into the green zone along with metrics and analytics, for example here (mobile 97, pc 100)
