The part of a URL that names one page, such as my-first-post in /blog/my-first-post. A CMS usually builds it from the title when you first save a post, and changing it later changes the page’s address.

Should a slug use hyphens or underscores?

Google’s URL guidance recommends hyphens between words and advises against underscores. The Separator menu starts on hyphen, so snake_case and-hyphen becomes snake-case-and-hyphen. Underscore is there for a file name or a system that needs it: the same text gives snake_case_and_hyphen.

Does the slug affect SEO or ranking?

Google’s URL structure page recommends descriptive words and hyphens and talks about crawling; it does not say that a slug changes ranking. This tool makes a readable, lowercase, ASCII slug and makes no claim beyond that.

Why is my slug empty, or missing words?

Only A to Z and 0 to 9 can be written, so letters with no Latin form are left out. Привет мир gives an empty slug and lists п, р, и, в, е, т and м, and 日本語 title gives title with 日, 本 and 語 listed. Write a Latin spelling of those words in the input if they belong in the URL.

What happens to apostrophes and & in a title?

They are deleted, not turned into words or hyphens. It’s Here gives its-here, Rock & Roll gives rock-roll, AT&T Deals gives att-deals and Q&A: Part 2 gives qa-part-2. If the word matters, type it out first: Rock and Roll gives rock-and-roll.

Should a slug be lowercase?

Google treats URL paths as case sensitive, so /APPLE and /apple count as different URLs. The tool always lowercases, which keeps one spelling for each page.

About the Slug Generator

“Straße” becomes strasse and “Hello, World” becomes hello-world. The slug generator lowercases the text, spells out ß, æ, œ, ø and similar letters, drops accents, deletes punctuation and joins the words with single hyphens. Letters that have no Latin form, such as Cyrillic or Chinese, are left out and listed under the slug.

Letters that are spelled out

Letter	Written as
ß	ss
æ	ae
œ	oe
ø	o
ł	l
đ	d
ð	d
þ	th
ħ	h
ı	i
ŧ	t
ŋ	n

Capitals are lowercased first, so Æ and Ø give ae and o. Other accented letters, such as é, ü and ñ, are split into a base letter and an accent, and the accent is dropped.

Examples

Input	Slug	Left out
Hello, World	hello-world	(none)
Café Münster: 10 Tips	cafe-munster-10-tips	(none)
Müller	muller	(none)
Straße	strasse	(none)
Æsir & Ødin	aesir-odin	(none)
Łódź	lodz	(none)
Œuvre ÐÞ	oeuvre-dth	(none)
İstanbul	istanbul	(none)
ﬁne ① Ａ	fine-1-a	(none)
snake_case and-hyphen	snake-case-and-hyphen	(none)
日本語 title	title	日, 本, 語
Привет мир	(empty)	п, р, и, в, е, т, м

Compatibility forms such as the ﬁ ligature, ① and the full-width Ａ become plain ASCII. When the slug is empty the tool says there are no Latin letters or digits to build one from.

Turning a headline into a slug

Paste the headline, copy the slug into the permalink or URL field of your CMS, then read it once before you publish. The slug keeps only what it can write with a to z, 0 to 9 and hyphens, so a word carried by punctuation can vanish: C++ Tips gives c-tips and 50% Off gives 50-off. Shorten a long headline by hand; the tool never cuts words.

The same slug works as a file name for an image or a download, since it has no spaces or characters that need escaping.

How a title becomes a slug

The steps, in order: lowercase the text; spell out ß as ss, æ as ae, œ as oe, ø as o, ł as l, đ and ð as d, þ as th, ħ as h, ı as i, ŧ as t and ŋ as n; split accented letters and drop the accents (é becomes e); delete anything that is not a letter, digit, space, underscore or hyphen; turn each run of spaces, underscores and hyphens into one hyphen; trim hyphens from both ends.

Worked examples: Straße gives strasse, Æsir & Ødin gives aesir-odin and Café Münster: 10 Tips gives cafe-munster-10-tips. Accents are dropped letter by letter, so Müller gives muller, not the German spelling mueller.

Letters with no Latin form, such as Cyrillic or Chinese, are left out and listed under the slug: 日本語 title gives title and lists 日, 本 and 語, and a title in Cyrillic only gives an empty slug. There is no length limit. The Separator menu starts on hyphen; pick underscore and the same steps join the words with _ instead: Café Münster: 10 Tips gives cafe_munster_10_tips.

Fun Fact: In newspaper editing, a slug is a short name given to an article that is in production. Web publishing uses the same word for the name of a page in its URL.
