Frequently Asked Questions

What is an SEO-friendly URL slug?

A short, descriptive, lowercase URL segment using hyphens to separate words that clearly signals page content to search engines and users.

Should I use underscores (_) or hyphens (-) in URLs?

Always use hyphens (-); Google's search algorithms treat hyphens as word separators, but treat underscores as joining characters.

How long should a URL slug be?

Keep slugs concise (typically 3 to 5 key words); shorter URLs are easier to share and achieve higher search CTR.
