Answer: Hyphens in URLs do not harm SEO when used correctly. Search engines like Google treat hyphens as word separators, improving URL readability for bots and users. Best practices include using 2-3 hyphens maximum, avoiding underscores or spaces, and prioritizing descriptive keywords. Overuse may reduce professionalism but won’t directly impact rankings if content quality remains high.

How Do Search Engines Interpret Hyphens in URLs?
Search engines recognize hyphens (-) as preferred word separators in URLs according to Google’s Webmaster Guidelines. They process “example-page” as two distinct words but read “example_page” as a single string. This parsing behavior helps search algorithms categorize page content accurately, unlike spaces which get converted to “%20” in encoded URLs.
Different search engines handle hyphens with remarkable consistency. Bing’s Webmaster Tools explicitly state that hyphens help “break up keywords for better indexing,” while Yandex treats them similarly to Google. A 2023 study by Ahrefs revealed that URLs with hyphens receive 37% more organic keyword variations in search results compared to underscore-based URLs. This occurs because algorithms can extract individual terms from hyphenated strings to match long-tail queries.
| Separator | Search Engine Interpretation | Recommended |
|---|---|---|
| Hyphen (-) | Word boundary | Yes |
| Underscore (_) | Character connector | No |
| Space | Encoded as %20 | Avoid |
How Does URL Readability Affect User Experience and CTR?
Hyphenated URLs increase click-through rates by 12-15% according to Backlinko studies. Users scan URLs in search results and social shares – clear structures like “blog/seo-tips-2024” communicate content focus better than ambiguous formats. Readable URLs also improve accessibility for screen reader users and reduce link-sharing errors.
The cognitive load reduction from hyphenated URLs is measurable. Eye-tracking studies show users spend 19% less time deciphering hyphenated URLs versus alternatives. In e-commerce, product pages with clean URL structures see 8% higher conversion rates, as customers trust transparent linking formats. Social media platforms like Twitter and LinkedIn automatically truncate complex URLs, making hyphenated short slugs crucial for maintaining context in shared links.
What Are the Technical SEO Implications of Hyphenated URLs?
Hyphens improve crawlability by creating machine-readable structure without affecting page load speed or indexing. Technical benefits include:
- Clear keyword separation for search bots
- Lower risk of encoding errors vs spaces
- Compatibility with XML sitemaps
- Easier canonicalization
What Are the Best Practices for Hyphen Usage in URLs?
Follow these URL hyphen rules:
- Place primary keywords first
- Use lowercase letters exclusively
- Limit to 3-5 words per URL
- Avoid special characters beyond hyphens
- Keep under 115 characters
- Maintain consistent casing (all lowercase)
How Do Hyphenated URLs Compare to Underscores in SEO Value?
Google explicitly recommends hyphens over underscores for word separation. Underscores create compound terms (“red_shoes” = “redshoes”) while hyphens maintain distinct keywords (“red-shoes”). This distinction impacts keyword targeting accuracy and featured snippet eligibility. Bing and DuckDuckGo follow similar parsing conventions.
Can Excessive Hyphens Trigger Spam Filters?
While no official penalty exists, URLs like “buy-cheap-shoes-online-discount-sale” may trigger quality raters to flag content as low-value. Moz research shows pages with 4+ hyphens have 22% lower dwell times on average. Maintain balance – use hyphens only where needed for clarity, not as keyword stuffing vehicles.
How Do Hyphens Impact International SEO Strategies?
Hyphens work better than underscores for multilingual sites using non-Latin scripts. They help separate transliterated keywords in Cyrillic or Asian languages without encoding issues. For hreflang implementations, consistent hyphen use across country variants (e.g., example.com/en-us vs example.com/es-mx) improves geo-targeting accuracy.
Expert Views
“Hyphens serve as critical semantic markers in URL architecture. Our A/B tests show properly hyphenated URLs increase featured snippet eligibility by 18% compared to underscore equivalents. The key is strategic usage – treat hyphens as content organizers, not ranking tools.”

Conclusion
Hyphens in URLs remain an SEO best practice when implemented judiciously. Their primary value lies in enhancing content comprehension for both search engines and users, indirectly supporting ranking factors through improved crawlability, CTR, and content relevance signals. Avoid hypen obsession – focus on creating logical URL structures that authentically represent page content.
FAQ
- Should I edit old URLs to add hyphens?
- Only if the URLs have significant traffic/ranking issues. Use 301 redirects carefully, as mass URL changes can temporarily impact crawl efficiency.
- Do hyphens help with voice search optimization?
- Yes – voice assistants parse hyphenated URLs more accurately when reading results aloud, improving contextual understanding by 23% according to SEMrush data.
- How many hyphens are too many?
- Aim for ≤3 hyphens in most URLs. E-commerce product pages may require 4-5 for proper categorization, but ensure the URL remains scannable within 2 seconds.
