Turn a headline into a clean URL slug

A slug is the readable part of a URL after the domain — the free-ai-detector in example.com/free-ai-detector. Paste a title, get a slug: lowercased, accents folded, punctuation dropped, spaces replaced with hyphens.

You can choose the separator and optionally strip stop words to shorten the result.

What makes a good slug

  • Hyphens, not underscores. Google treats a hyphen as a word separator and an underscore as a joiner, so ai_detector can read as one token.
  • Lowercase throughout. Paths are case-sensitive on most servers, so /About and /about are two URLs serving one page.
  • Short, but complete. Three to five meaningful words. Truncating mid-phrase to save characters helps nobody.
  • Stable. Changing a slug after publication breaks every existing link unless you set up a 301 redirect. Getting it right first is cheaper.
  • No dates or IDs unless the content is genuinely time-bound. /post-4471 tells a reader nothing.

Should you remove stop words?

Stripping "the", "a", "of" and similar shortens a slug, and it does no harm to how the page is understood. But it is a small effect, and it can make the URL read strangely: "how-detectors-work" instead of "how-ai-detectors-work" loses the word that mattered.

Strip stop words when a title is long and unwieldy. Leave them when removing them would make the slug ambiguous or awkward to read aloud.

Accents, symbols and other languages

Accented characters are folded to their closest ASCII equivalent, so "café" becomes "cafe". This avoids percent-encoding, which turns a readable URL into caf%C3%A9 when copied and pasted.

For a language that does not use the Latin alphabet you have a real decision: transliterate for a portable URL, or keep native script for readability among the people who actually speak it. Modern browsers display encoded Unicode URLs correctly, so native script is a defensible choice — just be consistent across the site.

Frequently asked questions

Hyphens. Google treats hyphens as word separators and underscores as joiners, so an underscored slug can be read as a single long token.
Only when the number is part of the meaning — "10-best-tools" or a model year. Auto-incrementing post IDs add length without adding information.
Long enough to describe the page, short enough to read in a search result. Three to five meaningful words is a reasonable working range; there is no penalty threshold.
You can, but the old URL will 404 unless you add a 301 redirect from old to new. Without that you lose any accumulated links and rankings for that page.
