Will SEO fail when transferring a domain?

Question

Search Engine Optimization

I welcome everyone!
There is a business card site made in the constructor. Search engine optimization is set up, everything works.
If you make a copy of this site, place it on a hosting and link the same domain that is linked to the site now, nothing will go wrong in terms of SEO?

Answer 1

if there are no errors, if nothing structurally changes, and the move occurs "seamlessly" (i.e. there is no period when the response from the series "there is no such site" appears at the site address), then everything will be OK.

Answer 2

If you make a copy of this site, place it on the hosting and link the same domain that is currently linked to the site
This is not called "domain transfer", but "hosting change".
And if the internals (files, engine, etc.) also change, then "engine change".
In the first case, nothing will happen if you do not screw up.
In the second transfer 1-in-1 is almost impossible. And if by "constructor" you mean the wix type, then everything is much worse.

Answer 3

It's probably better to show the site that you currently have built on the constructor. In general, if the project is commercial and you are not confident in your abilities, then order the transfer from specialists.
