How accurate is the form analysis in Yandex Metrica?

Question

Yandex

Good afternoon everyone!
In the analysis of Yandex forms, statistics count metrics not from the number of unique users, but from the number of page visits.
For example: 2000 page visits per day - 300 opened the form - 100 filled out.
In my opinion, 300 and 100 are closer to the designation as "unique users". It is unlikely that the same people will fill out the form several times.
Although the achievement of the goal was recorded for the same period of time - 50. It turns out that after all the same people sent contacts several times.
How do you navigate these statistics? I would like to get more or less accurate data. Does anyone have any experience on this topic?

Answer 1

Many people fill out the form incorrectly (whether intentionally or through inattention) and the data is not sent , but the achievement of the goal is triggered . To prevent this from happening, you need to set the target to an event that occurs after the successful submission of data , for example, opening a thank you page.
But even the standard setting of the goal to onclick or onsubmit gives some opportunity for a comparative analysis of the effectiveness of the page during testing. True , with small statistics - with a very large error :(
