Is it possible to deceive the search engine into having a mobile version of the site?

Question

Search Engine Optimization

There is a site.
We can't enable the mobile version at this stage.
Search engines write that there is no mobile version.
As I understand it, because of this, the position of the site is lower.
Is it possible to "deceive" the search engine, making it so that the mobile version = the full version of the site.
That is, the search engine will see the mobile version of the site, but in fact it will be a copy of the full version of the site.

Answer 1

Well, spend 3 hours on a primitive responsive, the main feature on mobile devices is to hide horizontal scrolling and then Google will consider that you have a mobile version,
it achieves this by

div {
width:100%;
overflow: hidden;
}

and hide unnecessary blocks

div {
display:none;
}

Answer 2

Maybe lower, but in the "mobile search", if you do not have a mobile version, then what for mobile users your site? :)
Maybe you just need to finish the mobile version, and not, as always, "let's all nai ***."
PS Bots renders the page, in order to deceive him, you need to give him content that he can take for a mobile version. Hmm, you need to make a mobile version then or give the main one but in some kind of Frankinstein :D
