We know HTML sitemaps can be useful for users, but is there any SEO value in them?If we’re already doing XML sitemaps and submitting that to Search Console, any SEO value in HTML sitemaps?
JOHN MEULLER (Webmaster Analyst from Google):
I don’t know. Sometimes. Sometimes it can definitely make sense to have these kind of HTML sitemaps, which are essentially a mapping of your category and your detail pages, especially if we can’t crawl a website normally otherwise. So if you have a really complicated navigation structure, maybe if you have pages that are almost connected just through search forms rather than a logical structure, then at least having one place where we understand the structure of the site, based on the links, that can really help us.
