How to Turn Any Title Into an SEO-Friendly URL Slug

To create a URL slug, paste your title into a slug generator and it lowercases the text, strips accents, removes special characters, and joins the words with hyphens — so "Café Résumé Tips" becomes "cafe-resume-tips". The slug updates live as you type and copies with one click, ready to drop into your CMS or code. It takes the guesswork out of building clean, valid URLs.

A slug is the readable part of a URL after the domain, and getting it right affects how your pages rank, how they read in search results, and how confidently people click and share them.

Why clean slugs matter for SEO

Search engines and humans both read the URL. A slug like /blog/best-running-shoes tells everyone what the page is about; /blog/post?id=48213 tells them nothing. Clean slugs improve click-through rates, are easier to share verbally, and avoid the duplicate-content traps that come from inconsistent capitalization. The Slug Generator enforces those best practices automatically, so bloggers, developers, and content managers get consistent, valid slugs every time instead of hand-editing each one.

How to generate a slug in your browser

1. Type or paste your title or phrase into the input box.
2. Choose your separator: hyphen (recommended for SEO) or underscore.
3. Watch the slug build live as you type — accents are stripped, symbols removed, and repeated separators collapsed.
4. Click Copy to grab the finished slug and paste it straight into your CMS or route.

Hyphens vs underscores: it actually matters

One of the oldest slug debates has a clear answer for SEO. Google treats a hyphen as a word separator but reads underscore-joined words as a single token, which changes how your keywords are understood.

Slug	How search reads it	Verdict
blue-widgets	Two words: "blue" + "widgets"	Recommended
blue_widgets	One word: "bluewidgets"	Avoid
Blue-Widgets	Case-sensitive duplicate risk	Avoid uppercase

Keep slugs to three to five meaningful words and drop filler like "a", "the", and "of" when they don't change the meaning. Short, lowercase, hyphenated slugs are the long-standing recommendation — and this tool applies all three defaults for you.

Frequently asked questions

What is a URL slug?

A slug is the descriptive, human-readable part of a URL that identifies a page — for example "my-first-post" in example.com/blog/my-first-post. Good slugs are short, lowercase, and use hyphens between words.

Should I use hyphens or underscores?

Use hyphens. Google treats hyphens as word separators but joins words connected by underscores, so "blue-widgets" reads as two words while "blue_widgets" may read as one. Hyphens are the long-standing SEO recommendation.

How does the tool handle accents and symbols?

Accented letters are normalized with Unicode NFD decomposition and the diacritic marks are stripped, so é becomes e and ü becomes u. Punctuation and symbols that are not valid in slugs are removed entirely.

How long should a slug be?

Aim for three to five meaningful words. Short slugs are easier to read, share, and rank. Drop filler words that don't change the page's meaning.

Can I use uppercase letters in a slug?

Technically yes, but you shouldn't. URLs are case-sensitive on most servers, so "My-Post" and "my-post" can be treated as different pages, causing duplicate-content issues. Lowercase everything — this tool does it automatically.
