Faceted navigation, such as filtering by color or price range, can be helpful for your visitors, but it’s often not search-friendly since it creates many combinations of URLs with duplicative content. With duplicative URLs, search engines may not crawl new or updated unique content as quickly, and/or they may not index a page accurately because indexing signals are diluted between the duplicate versions. To reduce these issues and help faceted navigation sites become as search-friendly as possible, we’d like to: Provide background and potential issues with faceted navigationHighlight worst practicesShare best practicesNew faceted navigation implementations or redesignsExisting faceted navigation implementations
