How to put matomo tracking code on non-wordpress page (same domain)?

Have matomo wordpress plugin. blog is “doomain.com/blog”. Want to put tracking code on “doomain.com” html page. How do I do that? (those are examples, not real links)

Do you know the matomo server URL?
Do you want to track on the same site or on another one (in the point of view of Matomo)?

the page i want to track is, as i said, the same domain, but not part of the blog on that domain. I don’t know if Matomo regards that as two sites or as a single site.

On your Matomo, can you add a new site (under Administration cog)?
