SEO Best Practices Guide for URLs & Permalinks
Hyphens vs. Underscores
Google Search Central documentation explicitly advises using hyphens (-) instead of underscores (_) in URLs. Google treats hyphens as word delimiters (e.g. seo-slug is parsed as two distinct keywords "seo" and "slug"), whereas underscores treat seo_slug as a single conjoined string.
Why Remove Stop Words?
Removing non-essential grammatical words such as the, in, of, and, a makes URLs shorter, more memorable, and maximizes keyword density. Concise permalinks fit cleanly on mobile browser address bars and snippet previews without getting truncated.
Transliteration Benefits
Accented characters (such as German ö or French é) often get percent-encoded by web servers (e.g., turning into %C3%A9), creating messy unreadable links. Transliterating them into ASCII equivalents produces robust, evergreen links that work seamlessly everywhere.
Frequently Asked Questions

Yes! Search engines treat uppercase and lowercase URLs as distinct pages unless canonicalized. Keeping all slugs lowercase prevents duplicate content penalization and 404 routing mismatches on Linux servers.
