What Is a URL Slug?
A URL slug is the human-readable part of a URL that identifies a specific page. In "https://example.com/blog/how-to-write-seo-slugs", the slug is "how-to-write-seo-slugs". Good slugs are short, descriptive, and use only lowercase letters, numbers, and hyphens.
URL Slug Best Practices for SEO
- Use hyphens, not underscores: Google treats hyphens as word separators; underscores join words (seo-tips ≠ seo_tips to Google)
- Keep it short: 3–5 words max when possible. Shorter URLs are shared more easily and easier to remember
- Include the primary keyword: the keyword in the URL sends a relevance signal to Google
- Lowercase only: URLs are case-sensitive on Linux servers; /My-Page ≠ /my-page
- Remove stop words: drop "a", "the", "and", "of", "in" when they don't add clarity
- No special characters: remove ?, &, #, %, commas, apostrophes
Should I change old URLs to better slugs?
Only with proper 301 redirects. Changing URLs without redirects breaks all existing backlinks and causes the old URL to 404, destroying accumulated SEO value. If you must change a URL, set up a 301 redirect from the old URL to the new one — this passes ~90% of link equity. Avoid changing URLs on pages that already rank well unless the benefit is significant.
How long should a URL slug be?
Google hasn't set a hard limit, but best practice is under 60 characters total for the slug. URLs longer than 115 characters get truncated in Google search results (showing "..."). Shorter, more focused URLs also tend to have higher click-through rates. Backlinko analysis of 11.8 million Google search results found a clear correlation between shorter URLs and higher rankings, though causation is debated.
