If you're managing a website, writing a blog, or doing SEO, you've probably heard the term 'URL slug'. It sounds like a garden pest, but it's actually one of the most important elements of your website's architecture.
What Even is a Slug?
A slug is the very last part of a URL that uniquely identifies a specific page on a website. For example, in the URL https://tools33.com/blog/what-is-a-url-slug, the slug is exactly 'what-is-a-url-slug'.
Why Slugs Matter for SEO
Search engines like Google read URLs to understand what a page is about before they even scan the content. A clear, readable slug gives Google a strong ranking signal. Furthermore, users are far more likely to click on a clean link rather than one containing random numbers like ?p=12345.
Best Practices for Writing Slugs
- Use hyphens to separate words: Never use underscores or spaces.
- Keep it short and descriptive: Usually 3-5 words describing the core topic.
- Filter out stop words: Words like 'a', 'the', and 'and' are unnecessary.
- Make it all lowercase: Capital letters in URLs can cause duplicate content issues on some servers.
