What is a URL slug and why is it important for SEO?

A URL slug is the user-friendly part of a URL that describes the page content, like 'how-to-create-slugs' in 'example.com/blog/how-to-create-slugs'. Good slugs improve SEO rankings by making URLs more readable for search engines and users, increasing click-through rates and helping with keyword optimization.

Should I use hyphens or underscores in URL slugs?

Always use hyphens (-) instead of underscores (_) in URL slugs. Google treats hyphens as word separators, making it easier for search engines to understand individual words in your URL. Underscores are treated as word joiners, which can negatively impact SEO performance.

How do I handle special characters and accents in slugs?

Special characters should be removed or converted to safe equivalents. Accented characters (é, ñ, ü) are typically converted to their basic forms (e, n, u) for global compatibility. Our slugify tool handles these conversions automatically, ensuring your URLs work properly across all browsers and systems.

What makes a good URL slug for SEO?

Good URL slugs are short (3-5 words), descriptive, use lowercase letters, include relevant keywords, avoid special characters, and use hyphens to separate words. They should be readable by both humans and search engines, helping users understand page content before clicking.
