Hyphens in Domains OK for SEO

Google has clarified that hyphenated domain names do not carry any negative SEO impact, suggesting that long-standing concerns within the industry may have been overstated.

Hyphens in Domain Names Confirmed as Acceptable

Google’s John Mueller has recently confirmed that the use of hyphens in domain names is perfectly acceptable from an SEO perspective. Despite being viewed by some in the SEO community as less desirable or even spam-like, there is no ranking penalty associated with them.

This clarification helps settle a debate that has circulated for many years, where hyphenated domains were often avoided due to perceived risks rather than confirmed algorithmic treatment.

A Look Back at Hyphenated Domains in SEO

In the early days of search engine optimisation, domain names containing keywords separated by hyphens were far more common. At the time, search algorithms were far less sophisticated and relied heavily on keyword matching.

This meant that domains structured around exact-match keywords often performed well, especially when combined with heavily optimised on-page signals such as keyword-rich titles, headings and anchor text.

During that period, it was also common for SEO practitioners to build large networks of keyword-focused domains, including hyphenated versions, which were used extensively for backlink strategies and affiliate sites.

There were even cases where such domains were leased or sold at scale for significant sums, reflecting the perceived value of keyword-rich naming conventions at the time.

Historical Use and Industry Adoption

Evidence from archived web directories such as DMOZ shows that hyphenated domains were once widely used across competitive industries. In some categories, a noticeable proportion of listed websites included hyphens in their domain names.

This highlights that, historically, such structures were not only accepted but also widely adopted in sectors where SEO competition was intense.

Google’s Official Position

John Mueller responded to a discussion on social media regarding the number of hyphens considered acceptable in a domain name, making it clear that hyphens are not a problem for SEO.

He noted that questions about whether dashes affect search performance are common, and confirmed that they do not negatively impact rankings. He also added a light-hearted remark suggesting there is no strict limit on the number of hyphens, though excessive use is uncommon in practice.

Are Hyphenated Domains Seen as Spam?

Within SEO circles, hyphenated domains have often been associated with spammy practices, largely due to their historical use in low-quality or automated sites.

Over time, as search algorithms improved, many of these types of websites lost visibility. However, this change is more likely linked to overall site quality and evolving ranking systems rather than the presence of hyphens themselves.

In reality, hyphens can improve readability by clearly separating words, making domain names easier to understand at a glance.

Real-World Examples of Hyphenated Domains

Many well-known organisations continue to use hyphenated domain names, including major global brands. Examples include Mercedes-Benz, Coca-Cola, T-Mobile, Harley-Davidson, and Merriam-Webster.

These examples demonstrate that hyphenated domains are not inherently penalised, as established companies continue to rank successfully using them.

Government and Institutional Usage

Hyphenated domain names are also used in official government and institutional websites. For instance, the U.S. government operates services such as e-verify.gov, which uses a hyphen to improve readability and clarity.

Without the hyphen, the name could be harder to interpret, showing that in some cases punctuation improves user understanding rather than hindering it.

Use in Web Standards Organisations

Even major technical organisations such as the World Wide Web Consortium (W3C) use hyphenated domains for certain projects. One example is Web-Platform-Tests.org, an open-source initiative supported by several major technology companies.

This further reinforces that hyphenated domains are not limited to low-quality or unofficial websites.

Should Businesses Use Hyphenated Domains?

Although Google has confirmed there is no SEO disadvantage, hyphenated domains are still not the first choice for many businesses.

There are practical reasons for this preference, including:

• They can be slightly harder to type, particularly on mobile devices
• They may appear less polished or less memorable
• Some users may associate them with lower trustworthiness

However, these concerns are largely related to user perception rather than search engine performance. In some cases, hyphens may even improve clarity by making a domain name easier to read and interpret.

Ultimately, the decision often comes down to branding rather than SEO limitations.

Final Thoughts

Google’s clarification reinforces the idea that hyphenated domains are not harmful for search visibility. While they may not be the most popular choice from a branding perspective, they remain a valid option for businesses and organisations.

The key takeaway is that domain structure alone is not a ranking barrier, and success in search depends far more on overall content quality and site authority than punctuation choices in the URL.
