RSS url of site

I am new enough to just now start trying to work with RSS. I want to submit my RSS url to RSS directories, as everyone involved in promotion tells me to do.

So, I just want to make sure this is correct:

My site, which is a static website rather than a blog, is https://bunionsonfeet.org

If I go the page source, the only thing I can see about RSS is that my url is https://bunionsonfeet.org/feed

It doesn’t have the “?rss” that I’ve seen in other RSS urls.

Is this correct? So, sll I do when I want to submit to a directory, add /feed to my website’ url?

I have two other static WP sites, and the page sources say the same thing.

I’m hoping someone here and confirm that this is correct, or point me in the right direction.
