What Is a URL Slug?

A URL slug is the part of a web address that appears after the domain name and identifies a specific page in a human-readable format. For example, in https://example.com/best-seo-tools, the slug is best-seo-tools. The term "slug" originates from newspaper editing, where it referred to a short label used to identify a story in production.

A good URL slug is short, descriptive, and uses only lowercase letters, numbers, and hyphens. It avoids special characters, spaces, and unnecessary words — making it easy for both humans and search engines to understand what the page is about.

Why URL Slugs Matter for SEO

URL slugs are a direct ranking factor and play a significant role in how search engines and users interact with your pages:

• Keyword relevance: Search engines use the words in your URL to understand page content. A slug like /seo-audit-checklist signals relevance more clearly than /page?id=12345
• Click-through rates: Users can preview what a page contains from the URL in search results. Descriptive slugs build trust and improve CTR
• Link sharing: Clean URLs are easier to share on social media, in emails, and in documents. They look professional and are more likely to be clicked
• Crawl efficiency: Simple, flat URL structures are easier for search engine crawlers to discover and index

URL Slug Best Practices

• Keep it short: Aim for 3-5 words. Remove stop words like "a", "the", "is", and "for" to keep slugs concise
• Use hyphens, not underscores: Google treats hyphens as word separators but may treat underscores as part of a word. Hyphens are the standard
• Always use lowercase: URLs are case-sensitive on most web servers. Lowercase prevents duplicate content issues from mixed-case URLs
• Include your target keyword: Place your primary keyword naturally in the slug — but avoid keyword stuffing
• Avoid special characters: Stick to letters, numbers, and hyphens. Special characters get URL-encoded (e.g., %20 for spaces) and look messy
• Make it evergreen: Avoid dates or time-sensitive words in slugs. A slug like /best-seo-tools ages better than /best-seo-tools-2024
• Set up redirects when changing slugs: If you update a slug on a published page, always create a 301 redirect from the old URL to preserve SEO equity

Frequently Asked Questions

What is a URL slug?

A URL slug is the part of a web address that comes after the domain name and identifies a specific page in a human-readable format. For example, in "https://example.com/best-seo-tools", the slug is "best-seo-tools". Slugs are typically lowercase, use hyphens to separate words, and avoid special characters.

Why do URL slugs matter for SEO?

URL slugs matter for SEO because search engines use them to understand what a page is about. A descriptive, keyword-rich slug like "/seo-audit-checklist" signals relevance more clearly than "/page?id=12345". Clean slugs also improve click-through rates in search results because users can see what the page contains before clicking.

Should I use hyphens or underscores in URL slugs?

Google recommends using hyphens (-) rather than underscores (_) in URLs. Google treats hyphens as word separators, so "seo-tools" is read as two words ("seo" and "tools"), while "seo_tools" may be treated as a single word. Hyphens are the standard convention for URL slugs and permalinks.

How long should a URL slug be?

URL slugs should ideally be 3-5 words or under 60-75 characters. Shorter slugs are easier to read, share, and remember. They also display fully in search results without being truncated. Remove stop words like "a", "the", "is", and "for" to keep slugs concise while retaining meaning.

Can I change a URL slug after publishing?

You can change a URL slug after publishing, but you must set up a 301 redirect from the old URL to the new one. Without a redirect, you will lose any SEO equity (backlinks, rankings) the original URL had accumulated, and users who bookmarked the old URL will get a 404 error. Use our htaccess redirect generator to create the redirect rules.
