Use a third party service if you don’t own a domain. NostrPlebs seems to be a common choice.

I have a domain for a website I use or is it a specific domain type? But I’ll also check out NostrPlebs
Normal domain (like the type you describe).
If you go to my profile you can see I’m using my personal domain (tannersilva.com) to verify my profile.
NostrPlebs may be easier…
If you have moderate experience with web hosting, you can look at this spec which defines how to verify on your own domain.
