What makes a good SEO slug?

Lowercase, hyphen-separated, under 60 characters, includes the primary keyword, and drops stop words. Avoid dates, query strings and ID numbers if you can.

Hyphens or underscores?

Google treats hyphens as word separators and underscores as joiners. Use hyphens for slugs (best-pizza-in-rome) and underscores only for code identifiers.

Will it handle non-Latin scripts?

Yes — Cyrillic, Greek, Vietnamese and most Latin-extended scripts are transliterated to ASCII. CJK characters are stripped because there's no widely accepted Latin transliteration.

Should I change slugs after publishing?

Avoid it. If you must, set up a 301 redirect from the old slug to the new one so you keep the page's existing backlinks and rankings.
