Inline tags are stripped, but frontmatter tags are parsed and added to a site-wide list which can be found under <sitename>/tags, see for example: https://obsidian-html.github.io/tags/

If you use slashes in your tags, these will be split into different pages (like a tree view).
E.g. adding the following frontyaml at the top of this note:

- type/parsing_markdown
- date/2022-02-04

Will result in a page https://obsidian-html.github.io/tags/type which will contain (among others) a link to parsing_markdown, which will link to this note.
