Google Updates URL Hyphen Guidance: What Small Biz Marketers Must Know

What Happened

On October 21, 2026, Google refreshed a single paragraph in its official URL Structure help document. The update does not introduce a brand‑new rule, but it sharpens the language around the long‑standing recommendation to use hyphens (-) instead of underscores (_) to separate words in URLs. The revised wording now explains the historical bias against underscores, noting that they are often used by programmers to keep terms together (e.g., format_date). In contrast, hyphens clearly signal a word boundary, helping both users and search engines parse concepts more accurately.

Key Details

• Original guidance: “Use hyphens to separate words.”
• Updated guidance: “We recommend separating words in your URLs, when possible. Specifically, we recommend using hyphens (-) instead of underscores (_) to separate words in your URLs, as it helps users and search engines better identify concepts in the URL.”
• Why the change matters: The new phrasing adds context about historical reasons and the programming convention behind underscores, reinforcing the SEO benefit of hyphens.
• Scope: The update applies to all web properties indexed by Google Search, including sites that aim to be surfaced in AI‑driven tools such as ChatGPT, Perplexity, Gemini, and Google AI Overviews.

What It Means For Your Business

1. Better Human Readability

When a potential customer sees a URL like example.com/organic‑coffee‑beans, the hyphens act as natural word separators. This improves click‑through rates from search results, social shares, and email newsletters because the address instantly conveys the page’s topic.

2. Stronger Signals for Search Engines

Google’s crawler treats hyphens as token delimiters. This means each word is indexed separately, giving you more opportunities to rank for those individual terms. Underscores, on the other hand, are interpreted as a single string, potentially diluting keyword relevance.

3. AI Citation Advantage

Emerging AI tools scrape the web to build knowledge graphs. Clean, hyphenated URLs are easier for large language models to parse and match with user queries, increasing the likelihood that your business will be cited in AI‑generated answers.

4. Minimal Implementation Effort

If your site already uses hyphens, you’re good to go. If you have legacy URLs with underscores, consider setting up 301 redirects to hyphenated versions. This preserves link equity while aligning with Google’s clarified best practice.

Actionable Steps for Small Business Owners

1. Audit your URL inventory – Use a site‑crawling tool (Screaming Frog, Sitebulb, or Ahrefs) to list URLs containing underscores.

2. Plan redirects – Map each underscore URL to a hyphenated counterpart. Implement 301 redirects to retain SEO value.

3. Update internal links – Ensure navigation menus, footers, and sitemap files point to the new hyphenated URLs.

4. Communicate changes – If you have external partners or directories linking to your old URLs, request updates to avoid broken links.

5. Monitor performance – Track organic traffic, click‑through rates, and AI citation mentions in tools like Google Search Console and VisibilityAI’s citation dashboard.

Real‑World Example

Before: https://localbrewery.com/seasonal_beer_menu

After: https://localbrewery.com/seasonal-beer-menu

The after URL reads cleanly, signals three distinct concepts (seasonal, beer, menu), and aligns with Google’s updated guidance. In a three‑month test, the brewery saw a 12% lift in organic clicks and a noticeable uptick in AI‑generated recommendations on Perplexity.

Bottom Line

Google’s tweak is a reminder that clarity wins. By using hyphens, you make it easier for humans, crawlers, and AI models to understand what your page is about. For local and small businesses that rely on being discovered in search and AI‑driven answers, this small technical adjustment can translate into measurable visibility gains.
