Faceted navigation, also known as faceted search or guided navigation, is a technique used in web development to enhance the search and filtering capabilities of a website or application. It allows users to refine and narrow down search results or browse through a large dataset by selecting multiple filters or facets.
Being a fairly complex way to filter and categorise data on a website, you can imagine that there are some big SEO implications involved with faceted navigation.

Faceted navigation can have a significant impact on search engine optimization (SEO) and the visibility of a website. One of the biggest issues is that it could create duplicate content - this may need controlling through the use of noindex tags, canonical tags or the robots.txt file. 

If implemented badly it can also create index bloat - causing issues with crawling and indexing of content. It's important that you understand all of the SEO risks before implementing or changing the use of faceted navigation on a site. 

Faceted navigation is really popular on eCommerce sites.
