Do words in the URL really still have a true impact on Google rankings?

Why does Google downplay the weight of URLs so much?

The evolution of Google's algorithms now relies on a deep semantic analysis of content rather than superficial technical signals. Early search engines heavily relied on URLs because they were an easy-to-parse indicator. Today, with natural language processing and machine learning models, Google can understand the topic of a page without relying on the words present in the address.

Mueller emphasizes the "very, very weak" nature of the signal — a somewhat unusual phrasing in official statements. This emphasis suggests that the algorithm places so little weight on URLs that their optimization becomes marginal or negligible within a broader SEO strategy. The engine prioritizes strong signals: content, backlinks, user experience, freshness, authority.

What does it really mean when we say "Google can essentially ignore"?

The phrase "essentially ignore" does not mean that Google completely eliminates this signal. It rather indicates that when more robust indicators are present, the weight of the URL becomes statistically insignificant in the relevance score calculation. If your content is well-structured with coherent Hn tags, a rich semantic field, and solid E-E-A-T signals, the URL becomes a secondary factor.

This functioning is especially observed on competitive queries where Google has thousands of signals to differentiate between pages. In ultra-specific niches or poorly documented long-tails, every micro-signal can play — but even in these cases, the URL remains a tertiary factor compared to content quality or internal linking.

Does multilingualism between domain/content really pose zero problems?

Mueller claims that a domain in a different language from the content creates no friction for Google. This is an important clarification for international sites using generic extensions (.com, .io, .co) with content in multiple languages. The engine relies on hreflang tags, the content itself, and other geographical signals to determine local relevance.

However, caution is warranted: this technical neutrality doesn't compensate for a mismatch perceived by the user. A .de domain with content in English may not incur an algorithmic penalty, but it can create UX confusion, indirectly degrading bounce rates or CTR in the SERPs. Google measures these user behaviors — and here, the signal becomes indirect but real.

• URL signal = marginal compared to Google's modern content analysis
• URL optimization ≠ waste of time, but should be weighted in SEO priorities
• Multilingualism between domain/content: no direct algorithmic penalty
• Prioritized strong signals: content, backlinks, E-E-A-T, Core Web Vitals
• Possible exception: ultra-specific niches with few competing signals

Is this statement consistent with what we observe on the ground?

Overall, yes. SEO tests conducted in recent years show that modifying a well-ranked URL to add a keyword rarely results in a measurable position gain, especially if the 301 redirect is clean and the content remains the same. Sometimes a temporary loss is even observed due to Google's reevaluation phase. The cases where the URL really moves the needle pertain to specific situations: poor content, lack of structured Hn tags, very young site with few external signals.

However, be cautious not to extrapolate this rule to the overall site architecture. A logical structure with clean URLs facilitates crawling, improves user experience, and strengthens internal linking. While it's no longer a direct relevance signal, it acts as a technical facilitator that indirectly impacts SEO. Mueller is discussing the weight of words in the URL, not the URL structure as such.

In what contexts might this signal still weigh in?

Let's be honest: in ultra-competitive queries where Google has hundreds of equivalent signals, even a marginal factor can differentiate two pages. But this scenario is statistically exceptional. In practice, if your page isn't ranking, the URL is never the blocking variable — it's the content, backlinks, search intent, or Core Web Vitals that are problematic.

A particular case merits attention: e-commerce sites with automatically generated URLs containing product IDs or alphanumeric strings. Even if Google ignores these URLs, they negatively affect the CTR in SERPs and user memorability. Therefore, URL optimization still holds UX and branding value, even if its pure SEO ROI becomes negligible. [To verify]: some SEOs still report micro-gains on very specific long-tails, but public data is lacking to quantify this phenomenon.

What nuances should we apply regarding this statement?

Mueller uses the phrase "if Google can analyze the content" — a condition that excludes poorly rendered JavaScript pages, content blocked by robots.txt, or sites with insufficient crawl budget. In these situations, Google may rely on available signals, including the URL. It’s not the URL that becomes important; it’s the absence of other signals that makes it relatively less negligible.

Another point: the psychological and organizational impact of clean URLs. A clear structure simplifies the work of editorial teams, streamlines SEO audits, and improves content governance. This operational benefit justifies maintaining a consistent URL convention, even if the direct algorithmic gain is low. Let’s not throw the baby out with the bathwater.

Should you still optimize the URLs of your new pages?

Yes, but for the right reasons. A descriptive URL improves the CTR in SERPs, facilitates sharing on social media, and enhances user understanding. Google displays the URL below the title in the results — a speaking URL (/seo-technical-guide vs /page-id-8472) generates more trust and clicks. This behavioral signal indirectly impacts ranking through user engagement.

For new pages, adopt a simple convention: short slug, main keywords separated by hyphens, without unnecessary stop-words. There's no need to stuff it with 5 variations of a query — one or two words are enough for readability. The goal is clarity, not algorithmic optimization. If your CMS generates clean URLs by default, stick with that system without over-optimizing.

What should you do with your existing URLs that are already ranking?

Leave them alone unless you have a solid technical reason (platform migration, restructuring, content merging). Modifying a well-ranking URL to add a keyword presents a risk greater than the hoped-for gain. Each change entails a 301 redirect, a reevaluation phase by Google, and potential technical bugs. The ROI is nearly nil.

If you absolutely must redesign, prioritize the overall coherence of the architecture over word-for-word optimization. Create a clear structure (/category/sub-category/page), document your rules for slugification, and test redirects extensively. The gain will come from the structure, not from words in each individual URL.

How should you prioritize your SEO efforts in light of this statement?

This clarification from Google allows you to reallocate time towards levers with greater impact. Instead of fine-tuning every URL, invest in writing quality, acquiring qualified backlinks, optimizing Core Web Vitals, and improving internal linking. These factors generate measurable and cumulative ROI.

For international or multilingual sites, focus on a clean implementation of hreflang, translated content (not automatically generated), and a local linking strategy. The fact that the domain is in a different language from the content becomes secondary if these fundamentals are strong. However, orchestrating these technical and editorial optimizations requires specialized expertise — many sites would benefit from support from a specialized SEO agency capable of finely auditing priorities and executing a coherent roadmap rather than scattering efforts on low-yield micro-optimizations.

• Keep descriptive URLs for CTR and UX, not for pure ranking
• Never modify a well-ranking URL just to add a keyword
• Prioritize coherent site structure > word-for-word optimization of slugs
• Invest heavily in content, backlinks, E-E-A-T, and Core Web Vitals
• For multilingual: impeccable hreflang + native content > domain language
• Document your URL conventions to facilitate editorial governance
