Frequently Asked Questions

What is an SEO-friendly URL slug?
A slug is the human-readable trailing segment of a URL path that describes the page contents. Clean slugs use lowercase characters and hyphens to convey clear topical relevance to both search engine crawlers and users.
Why are hyphens preferred over underscores in URLs?
Google and major search engines treat hyphens (-) as word separators, whereas underscores (_) may concatenate words into a single compound token. Hyphenated slugs optimize search indexing and readability.
Should stop words (like 'in', 'the', 'and') be removed from slugs?
Removing unnecessary stop words shortens the slug, increases keyword density, and makes URLs cleaner when shared across social channels.
What is the optimal character length for a URL slug?
Maintaining URL slugs between 40 to 60 characters is recommended. Concise slugs fit cleanly within search snippets and browser address bars without truncation.
