When it comes to SEO and URLs (or file names), hyphens (-) are better than underscores (_). Here’s why:

✅ Use Hyphens - (Recommended by Google)

  • Google treats hyphens as word separators.

    • For example: best-wedding-photography is read as “best wedding photography”

  • Improves readability for both search engines and users.

  • Google’s official SEO guidelines recommend using hyphens.

🚫 Avoid Underscores _

  • Google does not treat underscores as word separators.

    • best_wedding_photography is read as “bestweddingphotography”

  • That hurts your SEO and readability.

✅ Example Comparison:

URL Slug Google Reads As SEO Friendly
best-wedding-photography best wedding photography ✅ Yes
best_wedding_photography bestweddingphotography ❌ No

Final Verdict:

Always use hyphens (-) in URLs, slugs, file names, image names, etc., for better SEO.
