SEO slug rules of thumb

ASCII only: Google indexes ASCII URLs more reliably; non-ASCII often shows up as %E1%BB%A9.
Lowercase: /Foo and /foo are different URLs. Stick to lowercase.
Hyphens (-) over underscores (_): Google treats - as a word separator; _ joins words together.
Short: 3-5 words, under 60 chars is a sweet spot.
Keyword first: lead the slug with the primary keyword.
