How to remove non-existent pages from the search?

Question

Search Engine Optimization

There is a site loveyou.ua. It was recently radically updated and because of this, almost all links to sections, products, etc. have been changed. Already, as I understand it, the indexing of the site has passed, but the old links are still highlighted when searching.
Does anyone know how to remove them or will they disappear on their own?

Answer 1

themselves will disappear from the search, at the moment you can make a page with sections for a place 404
