How to migrate a website without losing SEO?

Question

Search Engine Optimization

Colleagues, good afternoon. Tell me, I need to transfer the site to wordpess. The old site on samopis. I moved all title,meta key,meta desc,h1-h3. The site has a very good SEO position. I don’t want to transfer the url structure, and the headings there are all crooked, to be honest. How to ideally transfer without loss of SEO? 301 redirect from old to new url and that's it? Or are there other nuances?

Answer 1

I moved all title,meta key,meta desc,h1-h3.

I hope this was done on a separate subdomain, closed from indexing.

301 redirect from old to new url and that's it? Or are there other nuances?

In general, that's all.
You can also add:
1. Leave the old version somewhere on a subdomain and close it from indexing. Then it will be easier to parse the url and match between them if something goes wrong.
2. Check basic redirects: from www to without www and others. Service to help https://apollon.guru/duplicates/
