A naive question about the metrics and direct, but don't they show us what we want to see on the web browser?

Question

Yandex.Metrica

They asked friends to help, launch in direct advertising a landing page for highly specialized seminars, so narrowly specialized that even simple spam / mailing to thematic addresses gave a bunch of registrations ...
And registration with them, I must say, in the form of a link button leading to a Google form. ..
So, I soldered Yandex metrics to that landing page, and the goal was to switch to the Google form, launch Yandex direct, and look at the web browser...
And here is the first oddity, even though the landing page was made on a bootstrap, it was made by blunt filling in some template that was not tailored for mobile devices and small screens, however, according to the webview, users admire the pictures that break the text, look at the paintings of great masters in an art gallery, instead of squandering them... And in general, someone examines and reads everything with interest, even what a specialist would squander along with the pictures.
Well, that's okay, but what's really incomprehensible is why people who left to fill out a Google form didn't fill out more than one? There would be 100500 fields or their unthinkable validation.
UPDATE: Yes, I forgot to mention one more important detail, the cherry on the cake, because I mentioned narrow specialization, but for you to understand the scale, keywords are asked less than three dozen times a month, they are cheap, special placement is almost empty, and competition with whom or not at all. That is, if this is a click fraud, then I'm asking whose :-)
Such activity would look natural for Internet commerce, but for seminars on Riemannian geometry for chefs! (a joke, but it captures the essence of the phenomenon)

Answer 1

Maybe you are misinterpreting the webvisor? Why did they decide that users "admire the pictures." It looks like the google form page was just loaded by some script, js of the metrics was executed and that was it. The script was not going to fill out the form. This script can be the search engine itself, some plugins, an advanced anti-spam analyzer, etc.

Answer 2

In Yandex.Metrica, you should at least set "filter robots according to strict rules and behavior" so that you can analyze something.
