Question

Search Engine Optimization

Hello. the site is at the top. Dedicated to narrow sports topics (video). And the situation is such that each new release is added by a new page (news, publication). And now I want to do it all in one player and put all the episodes in the playlist.
So in terms of seo what to do? there will be a lot of broken links... what to do with them, delete them through Yandex/Google webmaster or somehow hide all these links through robots.txt?
And will the search engines ban me for such manipulations?

Answer 1

Leave all the links in place, rewrite the player so that it can handle the HTML5 History API.
Launch the player from any page on the desired video, further navigation using Javascript.
