Do keywords in URLs really impact Google's ranking?

Why does Google downplay the importance of keywords in URLs?

Google's algorithm has evolved considerably since the 2000s. Back then, stuffing a URL with exact keywords could indeed influence positioning. Today, semantic understanding models like BERT and MUM analyze content as a whole, not just superficial signals.

A URL like /running-shoes-nike-men-2024 does not provide more value than a URL /running-shoes-men if the page content is identical. Google now prioritizes the contextual relevance of visible text, title and meta tags, and user behavioral signals.

Does this mean the structure of the URL is unimportant?

No. The statement specifically addresses inserting keywords, not the overall architecture. A logical and hierarchical URL structure remains essential for crawling and user experience. A URL like /blog/seo/keywords-url helps Google understand content categorization.

What is unhelpful is transforming /blog/seo/url into /blog/seo-seo-optimization/referencing/url-keywords-optimization-google in hopes of gaining a few positions. Readability and consistency take precedence over keyword stuffing.

What really matters in a URL according to Google?

Google recommends short, descriptive, and easy-to-share URLs. A good URL should give an idea of the page content without needing to view it. It's more of a signal for UX than a direct ranking factor.

URLs also play a role in link anchors. When a site copies and pastes your URL as anchor text, a clear URL generates a better signal than a cryptic URL like /p?id=12345. But again, it’s not keyword optimization that makes the difference, but semantic clarity.

• Very minor factor: inserted keywords in URLs have almost no influence on rankings
• Important structure: logical and hierarchical URL architecture remains relevant for crawling
• Readability is key: a clear URL enhances UX and can influence CTR in SERPs
• Natural anchors: a descriptive URL generates better link anchors when copied and pasted
• Avoid stuffing: multiplying synonyms and variations in slugs is counterproductive

Is this statement consistent with real-world observations?

Yes, overall. For several years, A/B testing on high-traffic sites reveals that modifying only the URL of a page without changing the content does not generate significant ranking variations. Instances where an impact is observed are often correlated with other changes: content redesign, improved internal linking, or updating tags.

However, there is one notable exception: exact match domains (EMDs). A site like car-insurance-paris.fr still enjoys a slight advantage for the query 'car insurance paris', but this effect comes from the domain name, not the URL slug. [To be verified]: Google has never precisely quantified the gap between EMD and non-EMD for recent competitive queries.

What nuances should be added to this statement?

Mueller's statement mainly targets keyword stuffing practices in URLs. It does not mean we should switch to completely abstract URLs. A URL that naturally includes the main subject of the page remains preferable to a generic URL like /article-123.

Another nuance: the impact on CTR. A visible URL in the SERPs containing the searched keyword may reassure users and improve click-through rates. This is not a direct ranking signal, but it indirectly influences performance through behavioral signals. Google observes pogo-sticking, session duration, and these metrics can ultimately affect ranking.

In what cases does this rule not fully apply?

On multilingual or multi-regional sites, the presence of localized keywords in the URL can enhance the consistency of geographical signals. For example, /fr/running-shoes vs /en/running-shoes helps Google associate the correct language with each version. This isn't keyword stuffing, it’s semantic structuring.

Similarly, for e-commerce sites with thousands of references, a URL that includes the exact product name facilitates crawling and disambiguation. A product page /nike-air-zoom-pegasus-40 is more easily indexable than a URL /product?ref=NK4578. But again, this is a matter of clarity, not forced keyword optimization.

What should you do with existing URLs?

If your current URLs contain keywords but remain readable and short, don't change anything. Massively altering established URLs to remove keywords would be counterproductive: you risk losing backlinks, breaking redirects, and diluting crawl history without measurable gains.

On the other hand, if you notice URLs stuffed with synonyms (/seo-natural-referencing-optimization-google-ranking), take advantage of a redesign or migration to simplify. Use clean 301 redirects to preserve SEO juice. The goal is not to eliminate all keywords but to eliminate unnecessary redundancy.

What mistakes should be avoided when creating new pages?

Don't fall into the opposite extreme: generic URLs like /page-1, /post-456, or /content?id=789 don't benefit anyone. A URL should remain self-descriptive. The right balance is a URL that reflects the main subject in a maximum of 3-5 words.

Avoid unnecessarily duplicating structures. If you already have /blog/seo/, creating /articles/referencing/ for the same type of content creates cannibalization and dilutes hierarchy. Google prefers clear architectures where each level has a distinct role.

How can I check if my URLs are optimized without being over-optimized?

Audit your URLs with a crawler (Screaming Frog, OnCrawl, Botify) and identify those exceeding 80 characters or containing more than 6 words. These are often candidates for cleaning. Also, check for unnecessary stop words: /the-complete-guide-to-optimizing-your-urls becomes /guide-optimizing-url without loss of meaning.

Then compare the CTR in Search Console between pages with short URLs and long URLs on equivalent positions. If you notice a discrepancy, it’s a signal that URL length influences user perception. Test rewrites on a few pilot pages before generalizing.

• Audit your URLs with a crawler to identify those exceeding 80 characters or 6 words
• Simplify URLs stuffed with synonyms during redesigns, using clean 301 redirects
• Create short and self-descriptive URLs for any new page (3-5 words max)
• Remove unnecessary stop words in slugs automatically generated by your CMS
• Check CTR in Search Console to measure the impact of URL length
• Maintain a coherent hierarchical architecture to avoid cannibalization
