How to make search engines find the new version of the page through the old one when changing the title?
I understand how to do it if I had a unique id in the address - it's easy, but what should I bind to when it doesn't exist?

Answer 1

1. store history in a separate table.
2. display id in the title, then you can pull id out of any title
3. do not change the title!

Answer 2

site/news/ID_nazvanie_novosti.html
