URL Slug Best Practices for SEO in 2026

URL slugs are one of the few on-page SEO elements you have full control over. In 2026, with Google’s AI Overview answering more informational queries directly, every technical SEO advantage matters. This guide covers the proven best practices for URL slugs that still move the needle.

1. Keep Slugs Under 60 Characters

Google displays up to about 512 pixels of a URL in search results, which translates to roughly 60 characters. Anything longer gets truncated with an ellipsis, reducing readability and click-through rates.

Short slugs are also easier to share in messages, emails, and social media. Compare:

/the-complete-beginners-guide-to-understanding-url-slugs-and-why-they-matter — too long, gets cut off
/url-slug-guide— concise, scannable, fits everywhere

Use our URL Slug Generator with the max-length option to enforce a character limit automatically.

2. Use Hyphens, Never Underscores

Google treats hyphens as word separators but treats underscores as word joiners. The slug url-slug-tips is read as three words, while url_slug_tips is read as a single token.

Google’s own documentation explicitly recommends hyphens. If you have existing content with underscores, consider migrating to hyphens with proper 301 redirects. The Kebab Case Converter can help you convert text to the correct hyphenated format.

3. Include Your Target Keyword

Place your primary keyword in the slug. If your page targets “react hooks tutorial”, the slug should be react-hooks-tutorial, not my-latest-programming-post.

Rules of thumb:

Put the keyword near the beginning of the slug when possible
Use one primary keyword, not multiple overlapping ones
Match the slug to user intent, not just keyword volume

4. Remove Stop Words

Stop words like “a”, “an”, “the”, “is”, “in”, “of”, “to”, and “for” add length without adding SEO value. Remove them unless they change the meaning:

“How to Build a REST API in Node.js” → build-rest-api-nodejs
“The Best Tools for Web Development” → best-web-development-tools

5. Use Lowercase Only

URLs are case-sensitive on most web servers. The URLs /My-Page and /my-page can serve different content, which creates duplicate content issues. Always use lowercase slugs and set up server-side redirects for any uppercase variations.

6. Avoid Dates in Slugs

Including the year or date in a slug (e.g., seo-tips-2026) creates two problems:

The content looks outdated the moment the year changes, even if you update the content
Changing the slug to update the year breaks existing links and requires redirects

Keep dates in the page title if needed, but leave them out of the slug. Use seo-tips instead and update the content regularly.

7. Never Change Published Slugs Without Redirects

Once a page is indexed, its URL is its identity. Changing the slug without a 301 redirect means:

All existing backlinks point to a 404 page
Google loses the page’s ranking history
Users who bookmarked the page can’t find it

If you must change a slug, always set up a 301 redirect from the old URL to the new one.

8. Use Flat URL Structures

Deep nesting adds no SEO value and makes URLs harder to read:

/blog/2026/05/category/tutorials/react-hooks — too deep
/blog/react-hooks-tutorial— flat and clear

Google can crawl deep URLs, but flatter structures are easier for users to understand and type manually.
