A URL slug is the part of a web address that identifies a specific page or post. For example, in example.com/blog/how-to-bake-bread, how-to-bake-bread is the slug.

What makes a slug SEO-friendly?

A good slug is short, readable, lowercase, uses hyphens between words, and contains the primary keyword. Avoid stop words, special characters, numbers without context, and long URLs.

Should I use hyphens or underscores in a slug?

Use hyphens. Search engines treat hyphens as word separators, so they are more readable and SEO-friendly than underscores, which can be interpreted as part of one word.

How do I generate a slug automatically?

Type your title into a slug generator. The tool lowercases the text, removes accents, spaces, and special characters, and joins the words with hyphens to produce a clean, shareable slug.

How to Create a URL Slug

A clean, descriptive URL is one of the quietest but most powerful SEO levers you own. And it all comes down to the slug — the last segment of your web address. This guide explains what a URL slug is, the rules that make a slug SEO-friendly, and how to generate one quickly and correctly.

What is a URL Slug

A URL slug is the part of a web address that identifies a specific page, post, or product. In the URL example.com/blog/how-to-bake-bread, the slug is how-to-bake-bread. The rest of the URL — the domain and the folders — just tells the browser where to look; the slug tells it what the page is actually about.

The word "slug" comes from journalism, where a slug was a short label used to identify an article before it was published. In modern web terms, a good slug does the same job: it gives you and the search engines a fast, human-readable signal of the page's content.

Because a slug becomes part of your permanent URL, it should be stable and descriptive. Changing a slug later forces your old links to redirect, and in a worst case you can lose rankings. Choose it well the first time, and your URL will serve you for years.

Rules for SEO-Friendly Slugs

Not every slug is good. Search engines and users both prefer slugs that are short, readable, and predictable. Follow these rules when you create one.

Keep it short. Aim for 3 to 5 words, or about 60 characters or fewer. Long URLs get truncated in search results and shared links.
Use lowercase. URLs are case-sensitive. Using lowercase everywhere avoids broken links caused by accidental capitalization.
Use hyphens between words. Search engines treat hyphens as word separators, so url-slug-generator is read as three words. Underscores can be read as one giant word, so avoid them.
Include your primary keyword. A slug that contains your main keyword gives both users and search engines a clear cue about the page topic.
Remove stop words. Words like "and", "the", "with", and "a" add length but little meaning. Drop them where you can.
Skip special characters and accents. Percent signs, spaces, emoji, and accented letters either break the URL or make it ugly. Strip them out.
Avoid numbers without context. A slug like /page-12 tells you nothing. Use words instead.

Here is a quick example: a post titled "5 Easy Ways to Improve Your Website's SEO" could become the clean, SEO-friendly slug 5-easy-ways-improve-website-seo.

How to Generate a Slug

You can craft a slug by hand, but it is the kind of task that is easy to get subtly wrong — an accent left in, a bad hyphen, an extra space. Here is how to do it well.

Manual approach

Write your title, convert it to all lowercase, remove punctuation and accents, then replace spaces with hyphens. Finally, cut any stop words and shorten the result until it is clean and descriptive. This works, but it is slow and error-prone when you have many pages or products.

Automatic slug generation

For most people, a slug generator is the smarter choice. You type your title, and the tool handles everything: it lowercases the text, strips accents and special characters, removes spaces, and joins the remaining words with hyphens in one step.

Use our free URL slug generator to turn any headline into a clean, SEO-ready slug in seconds. Paste your title, copy the resulting slug, and paste it straight into your CMS, store, or blog post. No sign-up, no download.

If you run a content site or an online store, generating slugs in bulk is a genuine time-saver. Instead of hand-editing dozens of product or post URLs, you can run your whole title list through the generator at once and stay consistent across your entire site.

Take a moment next time you publish to review the slug before you hit the button. A short, keyword-rich, hyphenated slug is one of the cheapest ranking and shareability wins available — and once the URL is live, it is very hard to change without losing the link equity you have earned.
