URL Slugs and SEO: Generate Clean Keyword-Rich URLs (2026)

A URL slug is the readable part after the last slash: /how-to-format-json. Keep it lowercase, hyphen-separated, 3-5 words, keyword-first.

Use the Slug Generator — handles Unicode, strips stop words, supports batch mode for CSV exports.

Common mistakes

• Uppercase letters or underscores
• Slugs longer than 5 words
• No keywords (e.g. /post-1)
• Changing slugs on ranked pages without a 301 redirect
