What is a URL slug and why does it matter for SEO?

A URL slug is the part of a URL that identifies a specific page, usually derived from the page title (e.g., /blog/how-to-write-better-slugs). A clean, keyword-rich slug improves SEO because Google uses the URL path as a ranking signal. Short, descriptive, hyphenated slugs perform best.

What does the slug generator do to my text?

The generator converts your text to lowercase, replaces spaces with hyphens, removes special characters and accents, strips stop words (optionally), removes multiple consecutive hyphens, and trims leading and trailing hyphens. The result is a clean, URL-safe string.

Should I use hyphens or underscores in URL slugs?

Google officially recommends hyphens (-) over underscores (_) in URL slugs. Google treats hyphens as word separators, so 'text-comparison-tool' is read as three separate words. Underscores join words ('text_comparison_tool' is read as one word), which hurts keyword matching.

How long should a URL slug be?

Best practice is to keep slugs under 60 characters and 3–5 words. Focus on the primary keyword of the page. Remove articles (a, an, the) and prepositions (of, in, for) to keep it concise. Shorter slugs are easier to remember, share, and click.

URL Slug Generator — SEO Best Practices

A URL slug is the human-readable part of a web address that comes after the domain name. For example, in https://example.com/my-blog-post, the slug is my-blog-post. A well-crafted slug is essential for both SEO and user experience.

Why Slugs Matter for SEO

Keyword inclusion: Search engines read URLs as ranking signals. Including your main keyword in the slug can boost rankings.
Readability: Users and search engines prefer clean, descriptive URLs over random numbers or parameters.
Click-through rate: A descriptive URL in search results increases the likelihood that users will click your link.
Sharing: Clean slugs are easier to share, copy, and type manually.

Slug Best Practices

Use hyphens (-) as separators — not underscores or spaces. Google treats hyphens as word separators.
Keep slugs short and descriptive — ideally under 60 characters.
Use only lowercase letters — avoid uppercase to prevent duplicate URL issues.
Remove special characters, punctuation, and accented letters.
Remove stop words (a, the, is, in) unless they're essential to meaning.
