Do keywords in URLs really affect Google rankings?

What is Google's exact stance on this matter?

John Mueller confirms what many have already suspected: optimizing URLs with keywords generates a weak signal in the ranking algorithm. Google considers these keywords, but their weight remains negligible compared to major criteria such as content quality or internal linking depth.

This statement contradicts a historical SEO practice. For years, URL optimization was presented as an important lever. Today, Google clearly outlines the hierarchy of factors: textual content and internal link structure overshadow everything else.

Why does Google still read URLs then?

Because the URL remains a useful contextual indicator in certain edge cases. When Google crawls a page without prior context, the URL provides a quick hint about the topic at hand. It’s a supplementary signal, not a structural ranking criterion.

In practice, it mainly assists with snippets and initial understanding during page discovery. A clear URL like /running-shoes-women helps Google categorize quickly, but it will never compensate for mediocre content or a failing link structure.

What is the real weight of content and internal linking?

Mueller emphasizes that these two factors dominate. Content generates the deep semantic signals that Google analyzes through BERT and MUM. Internal linking distributes PageRank and structures the site’s thematic understanding.

In concrete terms, a site with generic URLs (/p12345) but rich content and coherent linking will always outperform a site with keyword-stuffed URLs but lacking substance. The hierarchy is clear.

• Keywords in URLs generate a marginal signal, acknowledged but little valued by the algorithm
• Textual content remains the dominant criterion for semantic analysis and relevance
• Internal linking structures the distribution of PageRank and thematic understanding
• A clear URL assists with initial crawling and snippets but does not compensate for any strategic weaknesses
• Optimizing URLs without touching content or linking produces an almost null ROI

Is this statement consistent with field observations?

Absolutely. A/B tests conducted on high-traffic sites have shown for several years that modifying the URL alone to inject keywords generates no measurable variation in organic traffic. Cases that see a gain are consistently linked to other concurrent optimizations: title improvements, content enrichment, and the addition of internal links.

I have seen e-commerce sites completely redesign their URL structure thinking they would gain 20% visibility. Result: +0.5% at best, and sometimes a sharp drop when 301 redirects were poorly managed. The lost link juice during migration far outweighs the theoretical micro-gain from keywords in the URL.

In what cases does this rule not apply?

There are a few situations where the URL carries a bit more weight. Event or geo-targeted domains may benefit from a slight boost if the URL exactly matches a local query (e.g., /plumber-paris-15). But even there, the gain remains anecdotal compared to good content and solid Google Business Profile reviews.

Another edge case: sites with chaotic technical architecture where Google struggles to crawl effectively. In this context, a descriptive URL helps the bot prioritize important pages. But it’s just a band-aid on a wooden leg: the real problem remains the architecture itself.

What nuances should we consider regarding this statement?

Mueller is not saying that URLs are useless. He specifies that their impact on ranking is minimal. However, a clean URL improves CTR in SERPs, facilitates social sharing, and enhances memorability. These are indirect benefits that matter.

Also, be careful not to fall into the opposite extreme. Generating absurd URLs (/p?id=98234&session=xyz) complicates crawling and degrades UX. URL optimization remains a good SEO hygiene practice, but it is no longer a strategic ranking lever. [To Verify]: Google does not publish any numerical data on the exact weight of this signal, leaving a grey area.

What should you concretely do with this information?

Stop wasting time on URL redesigns if your content and linking are poor. Prioritize enriching the semantic content of your pages and redesigning your internal linking structure first. Once these foundations are solid, you can fine-tune the URLs, but don’t expect miracles.

If you're launching a new site, adopt a clear and descriptive URL structure from the outset: it's easier than migrating later. But if your site is already running, a URL migration solely for keywords is rarely justifiable given the risks of losing PageRank and technical costs.

What mistakes should you absolutely avoid?

Never redesign your URL structure without a solid 301 redirect plan. Every broken link, every multiple redirect chain, every unhandled 404 costs you juice. The risk far exceeds the potential gain from keywords in the URL.

Also, avoid keyword stuffing in URLs: /running-shoes-women-cheap-sales-promotion. Google detects these practices and they degrade UX. A URL like /running-shoes-women is more than sufficient. Readability takes precedence over keyword density.

How can you check if your site is effectively utilizing real levers?

Audit your internal linking with Screaming Frog or Oncrawl. Look at the distribution of internal PageRank: are strategic pages receiving enough links from the homepage and categories? Also check crawl depth: no important page should be more than 3 clicks away from the homepage.

On the content side, analyze semantic coverage with tools like SEMrush or Yourtext.guru. Do your pages genuinely cover the search intent? A generic 300-word content piece will never rank, even with a perfect URL. Aim for 1500-2000 words on pillar pages, with real thematic depth.

• Prioritize enriching content and optimizing internal linking before any URL redesign
• If you're launching a new site, adopt descriptive and clean URLs from the start
• Never migrate existing URLs solely for keywords without a clearly demonstrated ROI
• Ensure that each 301 redirect is unique, direct, and without chains
• Audit the distribution of internal PageRank and crawl depth
• Analyze the semantic coverage of your content with dedicated tools
