Use of Hyphens vs. Underscores in SEO

When it comes to search engine optimization (SEO), small details like how you structure your URLs can make a big difference in how your content ranks. One key aspect of URL structure is how words are separated. In this tutorial, we will explore the difference between using hyphens and underscores in URLs, and how this can impact your website's SEO performance.

What Are Hyphens and Underscores?

Hyphens (-) and underscores (_) are both characters used to separate words in URLs. They may seem similar, but search engines treat them differently.

Search Engine Preferences: Hyphens vs. Underscores

Search engines like Google have specific preferences for how URLs are structured. Google has confirmed that hyphens are treated as word separators, while underscores are not. This means that if you use an underscore, Google may not recognize the individual words, leading to possible ranking issues.

Here’s an example of how Google interprets hyphens and underscores:

1. Hyphens in URLs

When you use a hyphen to separate words in a URL, search engines like Google treat each word as a distinct keyword. This improves the clarity of your content and allows search engines to index the page more accurately.

Example: A URL with hyphens:

www.example.com/seo-best-practices

In this example, Google would recognize "seo", "best", and "practices" as separate keywords, which is beneficial for SEO.

2. Underscores in URLs

When you use underscores to separate words in a URL, Google treats the entire phrase as a single word. This means that the individual keywords may not be indexed correctly, which could negatively impact your page's rankings for those terms.

Example: A URL with underscores:

www.example.com/seo_best_practices

In this example, Google would likely treat "seo_best_practices" as a single term rather than recognizing "seo", "best", and "practices" as individual keywords.

Why Hyphens Are Preferred for SEO

Hyphens are the recommended choice for separating words in URLs for the following reasons:

  • Google treats hyphens as word separators, making it easier for search engines to index the individual keywords.
  • Hyphenated URLs are more readable for users, which can improve the click-through rate (CTR) when the URL appears in search engine results.
  • Search engines like Google have specifically recommended hyphens over underscores in URLs.

Real-World Example of Hyphens vs. Underscores

Consider an eCommerce website selling different types of shoes. Here's how their URLs might look with hyphens versus underscores:

1. URL with Hyphens

www.example.com/men-running-shoes

In this example, Google will recognize the individual keywords: "men", "running", and "shoes", which helps with SEO rankings.

2. URL with Underscores

www.example.com/men_running_shoes

In this case, Google may treat the entire phrase "men_running_shoes" as a single keyword, which could reduce the effectiveness of the URL from an SEO standpoint.

Best Practices for URL Structure

Based on SEO best practices, here are some tips for optimizing your URLs:

  • Always use hyphens (-) to separate words.
  • Avoid using underscores (_) or spaces in URLs.
  • Keep URLs as short as possible while still being descriptive.
  • Include relevant keywords in the URL to improve SEO.
  • Ensure URLs are easy to read for both users and search engines.

Conclusion

When optimizing your website for SEO, it’s crucial to use hyphens rather than underscores in your URLs. Hyphens are more SEO-friendly because they are recognized by search engines as word separators, while underscores can lead to indexing issues. By following these best practices, you can create SEO-friendly URLs that improve your site's rankings and enhance the user experience.
