A URL slug is the part of a web address that identifies a specific page, usually the last segment after the final slash. For example, in 'toolhivehub.com/blogs/slug-generator-guide', the slug is 'slug-generator-guide'. Good slugs are short, lowercase, and use hyphens instead of spaces.

Should I use hyphens or underscores in URL slugs?

Hyphens. Google's John Mueller has confirmed that Google treats hyphens as word separators in URLs, while underscores join words together. 'slug-generator' is read as two words; 'slug_generator' is read as one. Hyphens are the universal standard for SEO-friendly URLs.

Does a slug affect SEO?

Yes. The words in your URL slug are a minor ranking signal for search engines. More importantly, clean, descriptive slugs improve click-through rates because users can read what a page is about before clicking. They also make links easier to share and remember.

Should the slug match the page title exactly?

Not necessarily. It's common to shorten slugs by removing stop words ('a', 'the', 'and', 'in') while keeping the core keywords. For example, 'How to Create a URL Slug for SEO' becomes 'url-slug-for-seo' rather than 'how-to-create-a-url-slug-for-seo'.

Free URL Slug Generator: Create Clean, SEO-Friendly Slugs Instantly

Introduction

Every blog post, product page, and article on the web has a URL — and the part after the last slash is called a slug. A clean slug is short, descriptive, and uses hyphens between words. Our free slug generator converts any title, phrase, or sentence into a perfectly formatted URL slug in one click.

What Is a URL Slug?

A URL slug is the human-readable identifier at the end of a web address. Take this example:

https://toolhivehub.com/blogs/slug-generator-guide
                                ^^^^^^^^^^^^^^^^^^^^
                                This is the slug

Slugs replace spaces with hyphens, strip punctuation and special characters, and use only lowercase letters. They make URLs readable, shareable, and easier for search engines to understand.

Why Good URL Slugs Matter

SEO

Search engines read the words in your URL as a relevance signal. A slug like /tools/url-slug-generator tells Google what that page is about before it even crawls the content. Stop words (a, the, and) don’t add signal, so it’s fine to omit them.

User experience

People scan URLs before clicking links — especially in email, chat, or shared documents where the link isn’t styled as a button. A clean slug like /blogs/how-to-bake-sourdough builds trust; a messy one like /p=1482?ref=home&src=email doesn’t.

Permanence

URLs are hard to change once indexed. A good slug chosen at publication can stay valid for years. A bad one is awkward to redirect and can cause broken links if you ever clean it up.

Best Practices for URL Slugs

Keep it short. Aim for 3–5 words that capture the core topic. Search engines truncate long URLs in results pages.

Use your primary keyword. If your page targets “best noise-cancelling headphones”, your slug should include those words: /best-noise-cancelling-headphones.

Remove stop words. Words like a, an, the, and, of, in, to add length without adding meaning. Drop them unless they’re part of a brand name or change the meaning significantly.

Avoid dates in slugs — unless essential. /2026/05/blog-post-title locks your content to a time period and makes evergreen content look stale. Use dates only for news or time-sensitive content.

Never use spaces or underscores. Spaces get URL-encoded as %20, which is ugly and can break in some clients. Underscores join words in Google’s eyes rather than separating them.
