Why Does the Question of Accents in URLs Still Come Up?

For many years, accented characters in URLs were considered problematic for search engine optimization. Legacy systems encoded these characters in complex ways (example: "é" became "%C3%A9"), which created URLs that were difficult to read and potentially problematic for certain browsers.

Google has evolved, however. According to John Mueller, the search engine now perfectly understands accented letters and diacritical characters in URLs. There is therefore no longer any technical penalty for using them in their native form.

What Does This Statement Actually Mean for Google?

This announcement means that Google is capable of processing, indexing, and interpreting URLs containing accents correctly. The search engine can make the connection between "référencement" and "referencement" without difficulty.

This does not necessarily mean it's the best practice in all contexts. Technical compatibility alone is not sufficient to define an optimal URL strategy.

What Are the Key Takeaways from This Position?

• Google understands and indexes URLs with accents correctly
• There is no SEO penalty for using accented characters
• Compatibility applies to accented letters and diacritics from all languages
• If your URLs already contain accents, no need to modify them
• Automatic percent-encoding is still handled by modern browsers

Is This Statement Consistent with Practices Observed in the Field?

Yes, my observations confirm that Google has indeed been handling accented URLs well for several years. I've observed that sites with accents in their URLs can perfectly rank on the first page.

However, the technical reality goes beyond Google's simple crawling. Browsers, servers, and third-party tools (analytics, backlinks, social shares) may still encounter difficulties with these characters. This is where the real nuance lies.

What Nuances Should Be Added to This Recommendation?

Even though Google handles accents well, several practical constraints persist. Accented URLs are converted to percent-encoding (punycode) when shared, which makes them unreadable in certain contexts such as emails or SMS messages.

Additionally, some CMS platforms, plugins, or tracking tools may misinterpret these characters, creating duplicates or tracking errors. Backlinks from poorly configured sites can also generate broken URLs.

In Which Cases Is It Better to Avoid Accents in URLs?

For new projects, I systematically recommend URLs without accents to guarantee maximum compatibility. It's a matter of technical robustness and long-term portability.

For existing sites with accents, don't change anything: the cost of a migration (redirects, temporary loss of rankings, risk of errors) far exceeds the hypothetical benefit. The principle of "if it works, don't touch it" applies perfectly here.

What Should You Do Concretely Based on Your Site's Situation?

For a new site: Configure your CMS to automatically generate URLs without accents. Most modern systems (WordPress, PrestaShop, Drupal) offer this option natively in their permalink settings.

For an existing site with accents: Do nothing. Your URLs are properly indexed and any modification would require massive 301 redirects that present more risks than actual benefits.

For an ongoing redesign: This is the ideal time to standardize toward URLs without accents, since you'll be managing redirects anyway. Take advantage of this to optimize your entire URL structure.

What Mistakes Should You Absolutely Avoid?

The most serious error would be to launch a massive URL rewrite solely to remove accents on a production site. This mobilizes resources for zero SEO gain, or even negative gain in the short term.

Also avoid inconsistencies: if you choose to use accents, do it everywhere. If you choose to remove them, be systematic. Hybrid approaches create confusion and potential duplicate content.

Don't rely solely on official statements without testing your infrastructure. Some servers or configurations may require specific adjustments to properly handle UTF-8 encoding.

How Can You Check and Optimize Your Current Configuration?

• Audit your current URLs to identify the presence or absence of accented characters
• Verify that your server properly uses UTF-8 encoding in its HTTP headers
• Test sharing your URLs on different platforms (social networks, emails, messaging apps)
• Check in Search Console that Google is indexing your URLs correctly without creating duplicates
• For new content, configure your CMS to automatically standardize URLs
• Document your strategic choice (with or without accents) in your SEO editorial charter
• Train your editorial teams on the URL convention adopted
