Are keyword-rich URLs really useless for SEO?

What does Google really say about the weight of keywords in URLs?

Mueller is clear: keywords in the URL carry very little weight in the ranking algorithm. He even specifies that when the content of the page is indexed, these words play an "insignificant" role. This is a strong statement that leaves little room for interpretation.

The mention of AMP environments is interesting — Google indicates that URLs made up solely of numeric identifiers are perfectly functional, including in contexts where performance and structural simplicity are key. The algorithm does not penalize a URL like example.com/p?id=12345 compared to example.com/best-running-shoes, at least not significantly.

Why does this statement contradict a widely held SEO belief?

For years, descriptive URLs have been promoted as a must-have best practice. SEO guides consistently recommended including the main keyword in the slug. And rightly so: it seemed logical — if Google crawls and analyzes the text, why wouldn't it do so in the URL?

The reality is that the algorithm has evolved. Semantic understanding models (BERT, MUM, and their successors) rely on the actual content of the page, entities, contexts. A keyword-rich URL only provides a redundant signal compared to a well-written H1 title, a coherent meta description, and structured content.

In what context was this statement made?

Mueller made this position during discussions about AMP and modern architectures, where URLs are often dynamically generated with parameters or IDs. The goal was to reassure webmasters: migrating to a system of simplified or technical URLs will not harm SEO.

This fits into a broader trend from Google to deprioritize superficial on-page signals (like exact-match domains or keyword densities) in favor of more robust relevance signals: search intent, content quality, user behavior, domain authority.

• Keywords in the URL have very little weight in the ranking algorithm
• Numeric ID-based URLs are not penalized compared to descriptive URLs
• The content of the page largely outweighs the structure of the URL in the indexing process
• This position aligns with the evolution of Google's semantic algorithms (BERT, MUM)
• AMP and modern environments work perfectly with simplified technical URLs

Is this statement consistent with what we observe in the field?

Yes and no. In practice, descriptive URLs still have indirect utility: they improve click-through rates in the SERPs (a user is more likely to click on /seo-audit-guide than on /p?id=983), facilitate sharing on social networks, and make the site more navigable for the user. These are not direct ranking signals, but they do influence user behavior, which is a strong signal.

Then there is the case where keywords in the URL still matter a bit: link anchors. When an external site points to your page with the URL as the anchor (plain copy-paste), a descriptive URL conveys a clearer semantic signal than an ID. But even there, the impact remains modest compared to a good explicit anchor text. [To be verified]: Google has never precisely quantified this weight — we are navigating here in interpretation.

What are the risks of completely neglecting URL structure?

To say that keywords in the URL matter little does not mean one can do anything. A chaotic, overly long URL stuffed with unnecessary or cryptic parameters harms user experience and complicates crawling. Google can handle complex URLs, but it prefers clean structures.

There is also an issue of migration and redesign. If you change your URLs from a descriptive system to an ID system, you must manage 301 redirects, monitor temporary traffic losses, and ensure that backlink signals are properly transferred. The effort is rarely worth the trouble — unless you have a strong technical reason (microservices architecture, complex multi-locale, etc.).

What nuance should be added to this statement?

Mueller is talking about weight in the ranking algorithm, not the overall utility of URLs. A well-constructed URL remains an element of editorial consistency and navigation. It helps users find their way, share links, and remember pages.

Moreover, in certain contexts (e-commerce sites with thousands of references, UGC platforms, legacy CMS), descriptive URLs help technical teams: debugging, analytics, monitoring performance by categories. This is not pure SEO, but it matters in the site's overall ecosystem. [To be verified]: the exact impact of CTR related to URL structure in the SERPs has never been isolated by Google — we are working on observed correlations, not proven causalities.

Should you modify your existing URLs to remove keywords?

No, absolutely not. If your current URLs are descriptive and well-structured, making changes would result in broken redirects, lost backlink signals, and potential 404 errors. The SEO gain would be nil, or even negative. Leave your URLs as they are and focus on higher ROI leverage points.

However, if you are preparing a redesign or technical migration, you can simplify your URLs without worry — as long as you handle redirects properly and maintain logical coherence. The key is that the URL remains readable for users and technically clean for bots.

What should be prioritized if URLs matter so little?

Invest your time in content, Hn structure, title tags, and meta descriptions, which have a direct and measurable impact on ranking and CTR. Following that, work on Core Web Vitals, internal linking, and quality backlinks — signals that Google explicitly values.

If you have to choose between spending an hour perfecting your URLs or optimizing your featured snippets, the answer is obvious. URLs are no longer a priority project in a modern SEO strategy. They remain an element of care, but not a performance lever.

How to apply this logic to a new project?

On a new site, adopt a simple, short, and readable URL structure: no unnecessary words, no dates, no long nested categories. Prioritize clarity over keyword density. If your CMS generates automatic URLs based on the title, that’s sufficient — just clean up stop words and special characters.

If your architecture requires IDs or parameters (SaaS platforms, marketplaces, modern web apps), don't overthink it. Google accommodates this very well. Focus on canonical tags, clean XML sitemaps, and quality content. These are the elements that will make the difference in the SERPs.

• Never modify your existing URLs solely to remove keywords — the risk far outweighs the gain
• On a new project, favor short, readable URLs with no unnecessary words
• Invest your time in titles, Hn tags, meta descriptions, and content — they carry much heavier weight
• If you are using ID or parameter-based URLs, ensure your XML sitemap and canonicals are clean
• Meticulously manage 301 redirects in case of technical migration — this is the only real risk related to URLs
• Monitor CTR in Search Console — a clear URL can improve click rates even if it doesn’t boost ranking
