How to return site positions after moving to another domain?

Question

Search Engine Optimization

The essence of the problem: the site was on the old domain, got into the top 3 of the region for all targeted queries. It was decided to move to a new (shorter and more memorable) domain. The old address has taken off from the search engines, and the new one does not even come up in the search results.

Question: does it make sense now to upload a copy of the site to the old address and do the gluing?

Or can the problem of not getting a new site to the top of the issue be for other reasons?

Answer 1

Question: Does it make sense now to upload a copy of the site to the old address and make a gluing?

well, since you already did this before the move (did you?), then maybe

the problem of not getting a new site to the top of the issue may be for other reasons

Answer 2

Well, all the old positions and all the old link mass died, you invested hundreds of thousands of rubles in a new SEO to get to the top then?
And apparently the person or SEO who made this decision is a bit of an idiot.

Answer 3

It was necessary to initially collect and configure a redirect map. Especially for all the top pages - now you can’t do anything, only SEO from scratch. How long has the new domain been in operation?
