Using Hyphens vs. Underscores in Permalinks: Which Is Better?

by

When creating a website, one important aspect to consider is the structure of your permalinks or URLs. A common debate among web developers and SEO experts is whether to use hyphens (-) or underscores (_) in permalinks. Understanding the differences can help improve your site’s search engine ranking and user experience.

Permalinks are the permanent URLs to your individual pages and posts on your website. They serve as the address that visitors and search engines use to access your content. A clean and descriptive permalink structure is essential for SEO and usability.

Hyphens vs. Underscores: The Key Differences

Hyphens (-)

Hyphens are widely recommended by SEO experts because search engines interpret them as spaces between words. For example, my-article-title is read as “my article title,” making it more understandable for both users and search engines.

Underscores (_)

Underscores are less favored because search engines like Google treat them differently. Historically, underscores were not recognized as word separators, which could lead to less effective indexing. For example, my_article_title might be read as a single word or less clearly separated.

Which Is Better for SEO?

Most SEO experts recommend using hyphens in permalinks. Google’s own guidelines suggest hyphens as the standard separator for words in URLs. Using hyphens can improve your site’s visibility and click-through rates in search engine results.

  • Use hyphens to separate words in URLs.
  • Keep URLs short, descriptive, and relevant.
  • Avoid using unnecessary parameters or numbers.
  • Maintain consistency across your website.

By following these best practices, you can create user-friendly and SEO-optimized permalinks that help your content rank better and are easier for visitors to read and remember.
