Frequently Asked Questions

What is a URL slug?+

A URL slug is the human-readable, URL-friendly part of a web address that identifies a specific page. In the URL https://example.com/blog/how-to-write-better-slugs, the slug is "how-to-write-better-slugs". It should be descriptive, lowercase, and contain only letters, numbers, and hyphens — no spaces or special characters.

Should I use hyphens or underscores in URL slugs?+

Always use hyphens, not underscores. Google treats hyphens as word separators (so "seo-friendly" is read as two words: "seo" and "friendly"), whereas underscores are treated as character joiners (so "seo_friendly" is read as one word: "seofriendly"). This means hyphens produce better keyword matching in search. John Mueller of Google has confirmed that hyphens are the recommended separator for URL slugs.

Should I remove stop words from URL slugs?+

In most cases, yes. Stop words like "a", "an", "the", "of", and "in" add length without adding keyword value. For example, "how-to-write-the-best-seo-slugs" becomes "how-to-write-best-seo-slugs" — shorter and cleaner. However, if the stop word is part of a brand name or critical to meaning (e.g., "lord-of-the-rings"), keep it. Use your judgment and this tool's optional toggle.

How long should a URL slug be?+

Aim for 3–5 words (roughly 20–60 characters). Shorter slugs are easier to share, look cleaner, and are less likely to be truncated in search results and social media. Google's John Mueller has stated that Google does not have a specific length limit for URLs, but shorter URLs tend to perform better in practice. Avoid unnecessarily long slugs — trim stop words and redundant terms.

Do URL slugs affect SEO?+

Yes, slugs have a moderate impact on SEO. Including your primary keyword in the slug helps search engines and users understand what the page is about. Google confirms that keywords in the URL are used as a ranking signal, though it is a lighter signal than title tags and content. More importantly, descriptive slugs improve click-through rate because users can read what a page is about from the URL alone before clicking.

How should I handle non-English characters in slugs?+

Non-Latin characters (accented letters, Cyrillic, Arabic, Chinese, etc.) should be transliterated or romanized for maximum URL compatibility. While modern browsers and servers handle UTF-8 URLs, many tools and systems still have issues with non-ASCII characters. This tool automatically transliterates common accented characters (é→e, ñ→n, ü→u, ç→c) and strips characters it cannot transliterate. For non-Latin scripts, consider providing a manually transliterated alternative.

What about query strings and URL slugs?+

URL slugs are the clean path segment of a URL (e.g., /about-us or /product/blue-widget). Query strings (e.g., ?color=blue&size=large) come after the slug and are used for dynamic filtering. For SEO, prefer clean slugs in the path rather than relying on query strings for page identity — Google can crawl query parameters, but canonical paths rank more consistently.

URL Slugs and SEO: What the Research Actually Shows

A URL slug is the human-readable path segment of a web address — the part after the domain that identifies a specific page. In the URL example.com/blog/how-to-write-better-slugs, the slug is how-to-write-better-slugs. Getting slugs right is a foundational SEO task: it affects keyword matching, user trust, link-sharing behaviour, and how search engines understand your content hierarchy.

Hyphens vs underscores: the definitive answer

Use hyphens, not underscores. Google's own documentation and multiple public statements from Google engineers confirm that hyphens are treated as word separators in URLs. A URL containing seo-tips is understood as two separate words: “seo” and “tips”. A URL containing seo_tips is treated as one word: “seotips”. This distinction directly affects keyword matching for search queries. The underscore convention is a legacy from older systems where hyphens could not be used in identifiers — there is no reason to use underscores in modern URLs.

Should you change existing slugs for SEO?

If your existing pages already have rankings and backlinks, changing their slugs can hurt your SEO unless you implement proper 301 redirects from every old URL to the new one. A 301 redirect passes approximately 90–99% of the link equity from the old URL to the new one, but the ranking recovery typically takes days to weeks as Google re-crawls and re-indexes the pages. If your pages have no significant rankings or backlinks, updating slugs to be cleaner carries minimal risk. As a rule: the more established and linked a page is, the less you should change its slug without a very specific reason.

Slug length: shorter is almost always better

There is no hard character limit for URL slugs, but research consistently shows that shorter, keyword-focused URLs outperform long, multi-word slugs. Aim for 3–5 descriptive words. Avoid including dates, categories, or session IDs in slugs unless they add genuine value for users. Stop words (a, the, in, of) add length without adding searchable keywords — removing them makes slugs shorter and more scannable without losing meaning. For example, /guide-to-writing-seo-content becomes /seo-content-writing-guide after stop-word removal and reordering.
