Slug Generator

How it works

1. Transliterate letters without ASCII equivalents (ı→i, ß→ss, ø→o …)
2. Strip diacritics via Unicode NFD (ç→c, ğ→g, ş→s, ü→u, ö→o, é→e)
3. Lowercase · replace & with 'and' · collapse every non-alphanumeric run into one separator
4. Trim separators at both ends · cut at the last separator before the max length

About slugs

A slug is the human-readable part of a URL after the last slash. Good slugs are short, lowercase, use hyphens between words and contain only ASCII letters and digits — that is what search engines display cleanly, what people can read aloud, and what survives being pasted into chat apps and spreadsheets without percent-encoding.

Turkish, German and other diacritics are the usual source of ugly URLs: 'kâr-marjı' becomes '/k%C3%A2r-marj%C4%B1' when encoded. Transliterating to 'kar-marji' keeps the URL stable across every system. Google recommends hyphens over underscores because it treats hyphens as word separators.

Frequently asked questions

Hyphens or underscores?

Hyphens. Google treats a hyphen as a word separator and an underscore as a joiner, so 'roas-calculator' is read as two words and 'roas_calculator' as one. Use underscores only when a system requires them.

How long should a slug be?

There is no hard limit, but 3–6 meaningful words (roughly under 60 characters) keeps the URL readable in search results and social previews. Drop stop words like 'a', 'the', 'of' when the meaning survives without them.

Should the slug contain the year or a date?

Only if the page is genuinely about that period. A '2026' in the slug of an evergreen guide forces either a redirect or a stale-looking URL next year — put the year in the title, not the slug.

Does changing a slug hurt SEO?

Changing a live URL without a 301 redirect loses the page's rankings and links. If you must rename, redirect the old slug to the new one permanently and update internal links.
