How to transfer a new site to an old domain?

Question

Search Engine Optimization

Good day. There is an old site which is a landing. There is a new site which is made on Wordpress and is multi-page. It is necessary to transfer the new site to the old domain, but since the old site is well advanced in seo. Is it enough to just copy the content and meta tags and put the site in the old hosting folder? In some articles I read about a redirect, but I didn’t quite understand how to make it from a landing page to a multi-page one.

Answer 1

You do not need to do a redirect, it is necessary in a completely different case.
If you completely copy the content and tags and the maximum html of the landing page to the main page of the multipage, then this should be enough. But there is a high probability that the site will fall in the search, since Yandex has a special relationship with landing pages.

Answer 2

Why not do a redirect? It doesn't hurt to do it on a specific page. You also need to understand whether there was referral traffic, after all, links should lead somewhere
