Hi anyone!

If I prefix a dash to GUIDs in my URLs on my Web site, in this manner:

example.com/some/folders/-35x2ne5r579n32/page-name

Will my SEO rating be affected?

Background: On my site, people can look up pages by GUID, and by path. For example,
both example.com/forum/-3v32nirn32/eat-animals-without-friends
and example.com/forum/eat-animals-without-friends could map to the same page. To indicate that 3v32nirn32 is a GUID and not a page name, I thought I could prefix a - and then my webapp would understand.

But I wouldn't want my search engine rating to drop. And prefixing a dash in this manner seems weird, so perhaps Googlebot lowers my rating. Hence my question: Do you know if my search engine rating might drop? (Today or in the future?)

(I could also e.g. prefix id-, so the URL becomes example.com/forum/id-3v32nirn32, but then people cannot create pages that start with the word "id".)

(I think I don't want URLs like this one: example.com/id/some-guid.)

Kind regards, Magnus
