Content pages, paginated pages and locale variants should each be self-canonical. ## References - https://developers.google.com/search/docs/crawling-indexing/consolidate-duplicate-urls - https://developers.google.com/search/docs/specialty/ecommerce/pagination-and-incremental-page-loading ## More seo rules `void seo` reports 60 rules in this category.
