SEO Slug Generator

Why You Are Here

The slug is the human-readable part of a URL that sits after the domain and folders. In example.com/blog/how-to-make-sourdough, the slug is how-to-make-sourdough.

Most content management systems generate one automatically from your title, and the automatic version is usually acceptable and occasionally terrible. Titles contain punctuation, capital letters, question marks, ampersands, quotation marks, and accented characters, and different platforms handle each of those differently. A title like How to Make Sourdough, A Beginner's Guide (2026) can produce anything from a clean slug to a string of percent-encoded characters.

The first situation is publishing new content and wanting the slug right before it goes live. Getting it right at publication is the only time it is genuinely free to change.

The second is bulk work. Migrating a site, importing a product catalogue, or generating URLs for hundreds of pages where consistency matters more than any individual slug.

The third is handling non-English titles. Accented letters, Cyrillic, Arabic, and Chinese characters all need a decision about transliteration, and the default CMS behaviour is often not what you want.

What This Tool Does

The SEO Slug Generator takes any text and converts it into a valid URL slug.

Paste a title and the tool lowercases it, replaces spaces with hyphens, strips punctuation and special characters, converts accented letters to their closest plain equivalents, and collapses any repeated separators. The result is a slug that works in every CMS and every browser.

Everything runs in your browser. Nothing is uploaded or stored.

Before You Change an Existing Slug

This is the most important thing on this page

Changing the slug of a page that is already published changes its URL. The old URL stops working, and unless you handle it properly, three things happen at once: every backlink pointing at the old URL breaks, the page's accumulated ranking signals are lost, and anyone who bookmarked or shared the old link gets a 404.

A slug that is slightly less than perfect on a page with existing rankings and backlinks is almost always better than a perfect slug that resets the page's history.

If you do need to change it

Set up a 301 redirect from the old URL to the new one, permanently. Not a 302, which signals a temporary move and does not pass signals the same way.
Update internal links across your site to point directly at the new URL rather than relying on the redirect.
Expect temporary fluctuation. Even with a correct redirect, rankings typically wobble for a few weeks while search engines process the change.
Keep the redirect indefinitely. Removing it later re-breaks every old link.

Changing the slug IS worth it when	Changing the slug is NOT worth it when
The current URL is meaningless (/p=1234, /page-2-final-v3)	The current slug is merely imperfect
It contains a date that makes evergreen content look stale	The page already ranks well
It is misleading about the page content	The only motivation is squeezing a keyword in
The page has no meaningful traffic or backlinks to lose	The page has accumulated backlinks

Why Hyphens and Not Underscores

Every guide says to use hyphens. Few explain why, and the reason is specific rather than stylistic.

Google treats hyphens as word separators and underscores as word joiners

seo-slug-generator    ->  read as: "seo" "slug" "generator"
seo_slug_generator    ->  read as: "seosluggenerator"

# The underscore version reads as a single unrecognisable
# token rather than three meaningful words.

Underscores are also visually unreliable. Most browsers underline links, and the underline frequently obscures an underscore, so my_page can appear as my page or mypage when someone reads a link on screen.

Stop Words — The Nuanced Answer

Nearly every slug tool advertises automatic stop word removal, and nearly every SEO guide recommends it. The reality is more conditional than that.

Stop words are common function words like the, a, an, and, or, but, of, to, in, for, on, is, are. Removing them shortens slugs, which is often good. But removing them blindly damages some slugs:

Title	Stop words stripped	Better
How to tie a tie	tie-tie	how-to-tie-a-tie
The Who discography	who-discography	the-who-discography
Best IT jobs in Dubai	best-jobs-dubai	best-it-jobs-dubai
What is a VPN	vpn	what-is-a-vpn

In the first, the slug becomes nonsense. In the second, the band's name is destroyed. In the third, IT was misidentified as the pronoun. In the fourth, the entire query intent is lost.

A workable rule: remove stop words when the slug still reads naturally without them, and keep them when they carry meaning or the slug becomes awkward. Google understands stop words perfectly well, so there is no ranking penalty for leaving them in. The real benefit of removal is brevity, not relevance. Question-format slugs in particular usually read better with the question words intact, because how-to-tie-a-tie matches how people actually search.

Length Guidance

There is no hard limit and no penalty threshold. These are practical guidelines rather than rules.

Element	Target
Slug words	3 to 5
Slug characters	Under 60
Full URL	Under 100 characters where practical
Folder depth	2 to 3 levels maximum

Shorter slugs are easier to read in search results, survive being copied into messages and documents without wrapping, and are less likely to be truncated in the URL breadcrumb Google shows above each result. Long slugs are not penalised, they are just less useful to people.

Deep folder nesting is the bigger issue. A URL like /blog/2026/03/category/subcategory/post-title is difficult to maintain, and every folder level is another thing that breaks if you reorganise. Flatter structures are more durable.

Non-English and Accented Characters

Accented Latin characters should generally be transliterated to their plain equivalents.

Original	Transliterated
cafe (with acute e)	cafe
naive (with diaeresis)	naive
Zurich (with umlaut)	zurich
Sao Paulo (with tilde)	sao-paulo
Malaga (with acute a)	malaga

Non-Latin scripts are a judgement call, not a flat prohibition

Modern browsers and Google both handle UTF-8 URLs correctly, and Google displays them decoded in search results. So a Cyrillic or Arabic slug is not broken, and for a purely local audience it can be more readable than a transliteration.

The problem appears when the URL is copied. Outside the browser address bar, a non-Latin URL is percent-encoded, so a clean Cyrillic slug becomes an unreadable string of percent-sign sequences when pasted into an email, a message, or a document. Anyone sharing your link sees that version rather than the clean one.

Practical guidance: for a single-language audience where sharing happens mostly in-browser, native script is fine. For anything international, or where links get shared through email, chat, and documents, transliteration to Latin characters is the safer choice.

Slug Patterns by Content Type

Content Type	Pattern	Example
Blog post	Descriptive phrase	sourdough-starter-guide
How-to article	Keep the question format	how-to-fix-a-leaking-tap
Product page	Brand, model, key attribute	nike-air-max-90-white
Category page	Plain category name	running-shoes
Location page	Service plus location	plumber-manchester
Comparison	Item vs item	react-vs-vue
Landing page	Offer, no dates	free-seo-audit
News article	Topic, avoid dates	budget-2026-announcement

Avoid dates in slugs for anything evergreen. A URL containing /2024/ makes a page look outdated in search results even after you have updated it, and updating the content then leaves you choosing between a misleading URL and a redirect.

Common Mistakes to Avoid

Changing Slugs on Published Pages Without Redirects

This is the mistake most likely to cause real damage, and it is easy to make with a slug tool open. Improving the slug of a page that already ranks and has backlinks means the old URL 404s, every inbound link breaks, and the rankings the page had accumulated are lost. Always set up a permanent 301 redirect from the old URL before publishing the change, and leave that redirect in place indefinitely.

Ignoring That URLs Are Case-Sensitive

On most web servers, /My-Page and /my-page are different addresses. If both resolve, search engines can index both and treat them as duplicate content, splitting your ranking signals between two versions of the same page. Use lowercase for every slug without exception, and configure your server to redirect uppercase requests to the lowercase version.

Keyword Stuffing the Slug

A slug like cheap-shoes-buy-shoes-online-shoes-store-best-shoes looks like spam to people and provides no ranking benefit. URLs are a very lightweight ranking factor. The main value of a well-written slug is that someone reading it in search results understands what the page is about and is more likely to click. One clear phrase does that six repeated keywords do the opposite.

Frequently Asked Questions

What is an SEO slug generator?

An SEO slug generator is a free online tool that converts any title or phrase into a clean, URL-safe slug. It lowercases the text, replaces spaces with hyphens, removes punctuation and special characters, and transliterates accented letters. This SEO Slug Generator produces a slug ready to paste into WordPress, Shopify, Webflow, or any other content platform.

What is a URL slug?

The slug is the readable part of a URL that identifies a specific page, appearing after the domain and any folders. In example.com/blog/how-to-make-sourdough, the slug is how-to-make-sourdough. It describes the page content to both people and search engines in a form that is easy to read and share.

Should I use hyphens or underscores in URLs?

Hyphens, always. Google treats hyphens as word separators and underscores as word joiners, so seo-slug-generator is read as three distinct words while seo_slug_generator is read as one unrecognisable token. Underscores are also frequently hidden by link underlining, making URLs harder to read on screen.

How long should a URL slug be?

Three to five words, generally under 60 characters. There is no penalty for going longer, but shorter slugs are easier to read in search results, survive being shared without wrapping, and are less likely to be truncated in the URL breadcrumb Google displays. Clarity matters more than hitting a specific length.

Should I remove stop words from my slug?

Only when the slug still reads naturally without them. Removing stop words shortens URLs, but stripping them blindly can break meaning: how-to-tie-a-tie becomes the meaningless tie-tie, and The Who becomes who. Google handles stop words without difficulty, so keeping them carries no ranking cost. Remove them for brevity, not for rankings.

Can I change the slug of a page that is already published?

You can, but treat it as a URL change rather than an edit. The old URL stops working immediately, breaking every backlink pointing at it and losing the ranking signals the page had built. If you must change it, set up a permanent 301 redirect from the old URL to the new one, update your internal links, and keep the redirect in place indefinitely. For a page that already ranks well, an imperfect slug is usually the safer option.

Do URL slugs actually affect SEO rankings?

Only slightly and directly. URLs are a very lightweight ranking signal, and Google has been consistent about this. The real value of a good slug is indirect: it appears in the search result breadcrumb, so a clear, descriptive URL helps people decide to click, and that click-through behaviour matters considerably more than the keyword sitting in the URL itself.

Does this tool work with WordPress, Shopify, and other platforms?

Yes. The output is a standard URL-safe slug using lowercase letters, numbers, and hyphens, which every content platform accepts. Slugs generated with this SEO Slug Generator work in WordPress, Shopify, Webflow, Squarespace, Ghost, Drupal, Joomla, and any custom or headless CMS without modification.
