What is HTML Sitemap?

[grofee]

An HTML sitemap is a file that lists all the important pages of your website that you want search engines like Google and Bing to index. Indexing refers to how search engines gather your landing pages and store them in their database. The search engine refers to this database to respond to user search engine queries. If a homepage is not indexed, it can't be found and won't rank in search engine results.
