Pagination is when you have a post split into multiple pages which can be particularly useful when posts (or pages) get quite long and splitting the post into pages can help with page load times and be more user friendly when users read through those posts.
This is a little known feature of WordPress but is easy to implement.
Simply edit your posts in code/HTML view and enter:
Where you want the post to be separated into a new page… and that’s it!
The post will now show pagination or page numbers similar to Google Search results at the bottom of the post.
