What is a URL Slug?

A URL slug is the portion of a URL that appears after the domain and any subfolders. It is what makes a page unique within a website. URL slugs may look small, but they have a big impact. They tell search engines what your page is about, make links easier to understand, and help users feel confident about clicking.

Example:

  • Full URL: https://website.com/blog/url-slug
  • Slug: url-slug

Without a slug, links often look messy or confusing, like https://website.com/page?id=12345. A descriptive slug, on the other hand, clearly signals the topic of the page.

Why are URL Slugs Important?

URL slugs are important for both search engines and users.

SEO

Search engines read the words in a slug to better understand a page. While slugs are not the strongest ranking factor, including a target keyword can help reinforce relevance.

User experience

A clean slug reassures visitors they are in the right place. Compare /seo-basics with /p=9873. The first clearly describes the content, while the second gives no clue.

Shareability

Short, meaningful slugs are easier to share in emails, on social media, and in print. They look professional and trustworthy, which increases clicks.

In short, a good slug supports SEO, improves usability, and helps with link sharing.

What Are Examples of Good and Bad URL Slugs?

Good URL slug examples:

  • /content-optimisation
  • /short-url-guide
  • /qr-code-tracking

Bad URL slug examples:

  • /article-2345
  • /besturlshortener2025
  • /😊🚀

Good slugs are short, descriptive, and keyword-focused. Bad slugs are long, vague, or contain characters that make the link hard to use.

What Are the Best Practices for URL Slugs?

When creating URL slugs, follow these best practices:

Keep It Short and Descriptive

Use only the words needed to describe the page.

Example: /email-marketing instead of /how-to-build-an-email-marketing-strategy-for-small-businesses.

Use Hyphens, Not Underscores

Search engines treat hyphens as separators but may not with underscores.

Example: /best-tools not /best_tools.

Avoid Stop Words

Words like and, the, in add length without value. Instead of /why-the-sky-is-blue, use /why-sky-blue.

Stick to Lowercase Letters

URLs are case-sensitive. Keeping slugs lowercase avoids confusion.

Example: /seo-guide instead of /SEO-Guide.

Avoid Special Characters

Special characters, symbols, or emojis may break links or make them hard to share. Stick to letters, numbers, and hyphens.

Optimising slugs is a strong start, but marketers often need more. That’s where LittleLink comes in.

With Little Link, every URL can become measurable, trackable, and campaign-ready.

FAQs About URL Slugs

Do URL Slugs Affect SEO?

Yes, but only slightly. While not a major ranking factor, they help search engines and users understand the topic of a page.

What Is the Difference Between a URL and a Slug?

A URL is the full web address, while a slug is the part that comes after the domain.

Example: example.com/blog/seo-basics → slug = /seo-basics.

Can I Change a URL Slug?

Yes, but if you do, always set up a 301 redirect from the old slug to the new one. This prevents broken links and keeps your SEO value.
