Pagination

Pagination is the technique of dividing a long content list into numbered pages that a user navigates with links like "previous", "next" and page numbers. It's used wherever a dataset is too large to display at once — product listings, blog archives or search results.

How pagination works

Instead of loading hundreds of items in a single view, the application fetches and shows only a slice — say, twenty entries per page. Each page usually has its own URL, often with a page-number parameter (e.g. ?page=2) or as a clean path. This makes a specific page directly linkable, bookmarkable and indexable.

From the server's perspective, pagination eases the load on the database and speeds up rendering, because the query returns a limited set of records rather than the whole collection. That matters for large catalogs, where fetching every row at once would strain memory and lengthen response time.

Practical application

For SEO, correct pagination is essential to indexing deeper content. Crawlers need access to the links leading to subsequent pages in the HTML in order to reach products or articles beyond the first page. A common mistake is pointing the canonical tag from every paginated page back to the first — this can hide later items from the search engine.

An alternative to classic pagination is infinite scroll built on lazy loading, convenient on mobile but harder to index. A good practice is to combine both: smooth loading for the user, and classic, addressable pages behind the scenes for crawlers.
