Pagination is when content is split across multiple pages, making it easier for users to find what they need without feeling overwhelmed. While it can improve navigation, it also brings SEO challenges like duplicate content. To optimise paginated pages, use rel=”next” and rel=”prev” tags to show the sequence of pages, create unique titles and descriptions for each page, and wisely use canonical tags if needed. Just remember that good pagination keeps things user-friendly while helping your site rank better in search results.
