Are contextual ads loaded on mobile devices before clicking on another button?

Question

contextual advertising

Hello, I often see on sites such as avito or mamba a list of goods or something else. When you sit on a mobile device and scroll to the very bottom of the page, to the "Next Page" button, at that moment there is no advertising, BUT after a second it appears, and often it appears right before the click on the "Next Page" button and it turns out, you you click on the ad. I would like to know how you think this is specially made?
If so, how do users and AdSense with YAN feel about it?

Answer 1

gee gee
you understand that it is possible for one (mamba inside the account was allowed to show, yeah) - it’s impossible for others
, but it was done on purpose, yes
