What is a URL Slug?
A URL slug is the final part of a website’s web address path that identifies a specific page or article in a clean, human-readable format. For example, in the URL rtsall.com/tools/slug-generator/, the slug is slug-generator.
SEO Best Practices for Compiling Slugs
Search engines scan URL structures to establish quick topical context. Designing clean, readable slugs improves rankings and user CTR:
- Use Hyphens, Not Underscores: Search engine crawler indexing algorithms treat hyphens (
-) as space separators, while underscores (_) join words together. A slug likeurl-slug-generatoris parsed as four separate words, whileurl_slug_generatoris treated as a single word. - Keep Slugs Concise: Remove stop words (such as the, a, and, with) and limit lengths to 3-5 words focused entirely on your target keyword.
- Lowercase Only: Case-sensitive web servers treat uppercase and lowercase URLs as separate paths, which can create indexing duplicates. Keep slugs strictly lowercase.
Frequently Asked Questions
Q: What characters are removed by the generator?
It strips all punctuation symbols (question marks, commas, periods, quotes) and converts spaces into clean single hyphens.
Q: Can slugs contain non-English characters?
While URL encoders translate foreign characters to percent-encoded strings (like `%20`), it is best practice for general SEO to use standard Roman alphanumeric characters in slugs.
