A URL slug is the final segment of a web address that identifies a specific page. In rankpill.com/free-seo-tools/slug-generator, the slug is 'slug-generator'. Slugs are lowercase, use hyphens to separate words, and describe the page content in a few words.

Why are URL slugs important for SEO?

Search engines read URL slugs as a relevance signal. A slug containing your target keyword tells Google what the page covers before it reads a single word of content. Clean slugs also improve click-through rates because users can read the URL in search results and understand the topic instantly.

Should I use hyphens or underscores in slugs?

Always use hyphens. Google treats hyphens as word separators, so 'url-slug-generator' is read as three distinct words. Underscores join words together, meaning 'url_slug_generator' is treated as one word. Hyphens also look cleaner when shared as links and are less likely to break in email clients.

How long should a URL slug be?

Keep slugs between 3 and 5 words, typically under 75 characters. Shorter slugs are cleaner, easier to share, and less likely to be truncated in search results. Strip filler words like 'a', 'the', and 'of' unless they are part of the keyword phrase you are targeting.

Should I remove stop words from slugs?

For most pages, yes. Removing stop words keeps slugs short and keyword-dense. 'best-seo-tools' is cleaner than 'the-best-seo-tools-for-beginners'. However, if a stop word is part of a brand name or a phrase that only makes sense intact, keep it.

Can I change a slug after publishing?

Yes, but you must set up a 301 redirect from the old URL to the new one first. Without a redirect, any backlinks, social shares, and indexed pages pointing to the old URL will return a 404 error, and you will lose the ranking signals those links carried.

What is a URL Slug?

A URL slug is the human-readable part of a web address that comes after the domain name. In the URL example.com/blog/how-to-do-keyword-research, the slug is how-to-do-keyword-research. Slugs are always lowercase, use hyphens instead of spaces, and avoid special characters.

A well-crafted slug tells both users and search engines exactly what a page is about before they open it. This clarity is one of the reasons Google uses slugs as a lightweight ranking signal. Pages with keyword-rich, descriptive slugs tend to perform better in search results than pages with generic identifiers like ?p=1042.

Keep it short

Aim for 3 to 5 words. Shorter slugs are cleaner in search results and easier to share and remember.

Include your target keyword

Put the primary keyword near the front of the slug. Google gives more weight to words that appear earlier in the URL.

Always use hyphens

Hyphens separate words clearly for both search engines and humans. Underscores join words together and should be avoided.

Never change slugs without redirects

If you update a slug on a live page, set up a 301 redirect first to preserve rankings and avoid broken links.
