SEO-Friendly URL Slug Regex Patterns
Clean URL slugs improve readability, sharing, and SEO consistency. A good slug regex ensures you only allow lowercase characters, numbers, and hyphens, with no trailing separators.
Recommended slug regex
^[a-z0-9]+(?:-[a-z0-9]+)*$Why this pattern works
It enforces lowercase-only strings, prevents double hyphens, and avoids trailing separators. This aligns with SEO best practices for URL structure.
