Can't figure out why mobile SERPs make such a big difference?

Question

Google

Hello, tell me please, I can’t understand why, from the client’s mobile phone, the karabas.kz website, at the request of animators in Almaty, is on page 3, and when I check it is on 1. The client checks from the mobile phones of his employees, they have page 3, and if I check and my colleagues then 1. The Internet is different for everyone, who sits from his own, who from the corporate. On desktop, the site is on 1 page. Please tell me how to understand and explain to the client. I looked at the statistics and if he was on page 3, well, no one would find him and he would not have about 1000 users a month. All changes are considered relative to Google.

Answer 2

And what are you going to do with people like that)))
Yes, to conduct an experiment, obviously equal conditions are needed.
Therefore:
1. Take your mob. and go to him and his staff (just in case, grab brass knuckles)
2. Connect everything to the same network (for example, to wi-fi) to exclude geolocation factors
3. Turn on incognito mode
4. Try to google their funny animators with a minimum interval.
5. Look at the result.
6. If the result is very worthless - remember the brass knuckles in your pocket and mentally thank the one who advised you to take it with you.

Answer 3

because Google remembers its preferences among SEOs, there is even a joke about it,
you check something at least in incognito so as not to disgrace yourself
