Why is the position of the site different on different devices?

Question

Google

Good afternoon. There was such a question. Why do the positions of the same site change every time? The request is the same.
On the computer, for example, to 2 positions, and on the phone the same request - generally flew to 2 pages?
This happens both in Yandex and Google.

Answer 1

Search queries are individual . They depend on what "your personality profile" was compiled by Google / Yandex automation on a particular computer.
Turn off customization of search results first.
