Pagination is where the owner of a website can choose to split a specific page into multiple sections as part of a sequence. This is often used when the contents of a page is large and would be easier to read and load across multiple pages. You can tell when pages contain pagination due to it containing tags such as rel=‘Next’ and rel=‘Prev’ this indicates where each page falls in the sequence. ’Next’ and ’Prev’ tags help search engines like Google understand that the pages should all link back to the first original page in the sequence for indexing.

You can think of pagination like pages in a book.
