Pagination tags can be used to avoid duplicate content penalties and low indexation rates.
Pagination HTML commands (“rel = prev” and “rel = next”) on content that spills over into multiple pages, but should be treated as one. Pagination tags should be used on the “Next page” and “Previous page” links to alert search engines of this.
These tags are common on blogs, eCommerce sites, or longer guides.
