Free URL slug generator
A URL slug is the readable part of a web address after the domain — like /best-seo-tips/. This free tool — built by a Singapore SEO agency — turns any title into a clean, lowercase, hyphenated, SEO-friendly slug. Strip stop-words, cap the length, choose your separator and transliterate accents automatically. It updates live and copies with one click. Everything runs in your browser.
What makes a good URL slug
The best slugs are short, descriptive and keyword-focused. Use hyphens (not underscores) to separate words — Google treats hyphens as spaces but underscores as joiners. Keep it lowercase to avoid duplicate-URL issues on case-sensitive servers, drop filler words like “a”, “the” and “for” where they don’t aid clarity, and include your target keyword near the front. A slug of three to five meaningful words is usually ideal — long enough to be descriptive, short enough to share and remember.
Why URL structure matters for SEO
Clean, descriptive URLs help in several ways: they give search engines and readers a clear signal of the page’s topic, they look more trustworthy in search results and when shared, and they’re easier to link to. Google has said readable URLs can be a small ranking and usability factor. Just as importantly, a stable, sensible URL structure is easier to maintain — and avoids the messy, parameter-filled URLs that confuse both users and crawlers.
Changing slugs on a live site — be careful
Editing a slug on a published page changes its URL, which breaks existing links and can lose ranking signals unless you add a 301 redirect from the old URL to the new one. If you’re renaming URLs, generate the redirects too — our 301 redirect generator builds them for Apache, Nginx or WordPress. For brand-new pages, just set a clean slug from the start and you’ll never need to.
Frequently asked questions
Should I use hyphens or underscores in URLs?
Hyphens. Google treats a hyphen as a word separator but an underscore as a word joiner, so seo-tips is read as two words while seo_tips can be read as one. Always use hyphens in slugs.
Should slugs include stop-words?
Usually you can drop them for a cleaner slug, but keep them when removing them hurts readability or meaning. “how-to-rank-on-google” reads better than “rank-google”. Use the toggle above to compare.
How long should a URL slug be?
Short — ideally under about 60 characters and three to five meaningful words. Shorter slugs are easier to read, share and remember, and keep the keyword prominent.
Can I change a slug after publishing?
Yes, but set up a 301 redirect from the old URL to the new one so you don’t break links or lose SEO value. For new pages, choose a good slug from the start to avoid the issue entirely.
