Do localized words in your URLs really affect your Google ranking?

What does Google mean by "localized words" in a URL?

Google refers to translated or adapted terms to a specific language in the URL structure. For instance: /chaussures-running/ for France versus /running-shoes/ for England, or /laufschuhe/ for Germany.

The underlying question concerns multilingual and multi-regional sites. Should we fully translate the URL slugs for each language version? Or can we maintain a uniform English structure for technical convenience? Mueller's statement suggests that the search engine does not inherently favor one approach over the other.

Why is the impact on ranking negligible?

Google's algorithms no longer heavily rely on keywords present in the URL to determine a page’s relevance. That era has been over for several years. Modern ranking signals include page content, backlinks, domain authority, Core Web Vitals, and search intent.

The URL remains a weak signal, but its specific linguistic dimension provides only a marginal semantic micro-advantage. Google understands a page's content through its text, hreflang tags, and metadata — not through the slug translation.

Where does the real value of localized URLs lie?

The real impact happens during display in search results. A French user who sees "exemple.com/chaussures-running" immediately perceives that the content matches their language and context. This trust signal increases the click-through rate.

Mueller emphasizes that this user dimension justifies localizing URLs. The improved CTR indirectly enhances SEO through behavioral signals, but the localized URL itself does not directly boost algorithmic ranking.

• Translated words in the URL have virtually no impact on Google's ranking algorithms
• Their main value lies in improving CTR through user trust in SERPs
• Google understands a page's language and relevance through actual content, hreflang tags, and metadata, not through the URL slug
• The decision to localize URLs lies in a UX/technical trade-off rather than a pure ranking strategy
• An improved CTR can generate positive behavioral signals, creating an indirect effect on SEO

Is this statement consistent with field observations?

Yes, and it's rather refreshing. Empirical tests conducted on multilingual sites have shown for several years that translating slugs does not cause measurable ranking jumps. E-commerce platforms that maintain English URLs across all their language versions do not suffer visibility penalties if the rest of their international architecture is clean.

What really matters is the consistency of global linguistic signals. Correctly implemented hreflang tags, qualitatively translated content, geographical targeting through Search Console. The URL is just a detail in this whole. That said, the UX/CTR gain remains real, especially in markets where linguistic sensitivity is high.

What nuances should be added to this statement?

First point: Mueller refers to "little" significant impact, not "none". There likely exists a residual micro-signal of semantic relevance, but it is so weak that it gets lost among hundreds of other factors. In ultra-competitive queries, every detail counts — but even then, a translated URL won't change a position from 5 to 1. [To verify]: the exact extent of this impact remains unclear.

Second nuance: the display context. On mobile, URLs are often truncated or hidden. On desktop, they remain visible. Thus, the psychological effect of the translated slug varies by device. Finally, some cultural markets (Germany, Japan) place greater value on total linguistic coherence — a detail that may influence conversion beyond just clicks.

In what cases does this rule not fully apply?

Niche domains with low competition may still derive a micro-advantage from keyword-stuffed URLs in the local language, simply because other ranking signals are also weak. If no one has solid backlinks or exceptional content, the URL becomes relatively more important.

Another case: sites with a strongly aligned internal anchor text strategy with the slugs. If your internal linking systematically uses the translated URL as the anchor, you create a semantic consistency that can marginally reinforce topicality. But this is a very specific use case, not a general rule.

Should you translate the URLs of your multilingual site or not?

The answer depends on your trade-off between technical complexity and UX optimization. If you are launching a new site with solid dev resources, translating slugs brings a measurable CTR benefit without excessive cost. Set up a clean architecture right from the start with consistent localized URLs.

If your site already exists with unified English URLs and performs well, don't change anything. An URL migration carries risks (redirects, temporary traffic loss, hreflang errors) that far outweigh the marginal ranking gain. Focus your efforts on quality content and backlinks.

What mistakes should you avoid when localizing URLs?

Classic mistake: translating only certain levels of the hierarchy. You end up with hybrid URLs like /fr/running-shoes/chaussures-marathon/avis/ that break perceived coherence for the user. If you decide to translate, translate the entire path, or not at all.

Second trap: poorly encoded special characters. Accents, umlauts, cedillas must be either correctly URL-encoded (%C3%A9 for é) or transliterated (chaussures-ete rather than chaussures-été). Avoid slugs appearing as /chaussures-%C3%A9t%C3%A9/ in SERPs — the UX effect becomes counterproductive.

How can you verify that the international structure is optimal?

Start with a complete hreflang audit. Each language version must correctly point to its alternates, including itself (x-default included if relevant). Hreflang inconsistencies cause much more damage than untranslated URLs.

Next, check the geographical targeting in Search Console for each version, and ensure that servers respond quickly from the targeted regions. Analyze click-through rates by language in GSC: if a language version underperforms in CTR despite good impressions, translating URLs may be a secondary lever to activate.

• Audit hreflang tags and correct all errors before any other URL optimization
• If migrating URLs: plan perfect 301 redirects and monitor organic traffic week by week
• Correctly encode special characters or opt for clean transliteration
• Maintain total consistency: translate the entire URL path or keep everything in English, never hybrid
• Analyze CTR by language in Search Console to identify priority UX levers
• Test the mobile display of translated URLs to ensure they are not truncated in a counterproductive way
