Do keywords in the URL really still affect your ranking?

What does Google really say about the weight of URLs?

Mueller dismisses a deeply rooted belief among many SEO practitioners: the idea that a keyword-stuffed URL provides a tangible advantage. His position is clear — the impact is minimal. Not zero, but negligible compared to other factors.

What matters according to him is the internal linking structure. A clean URL mainly aids readability, enhances UX, and may reassure users quickly scanning the address in the SERPs. But what about pure algorithmic considerations? The effect is marginal.

Why this distinction between new and existing sites?

Mueller is clear: optimizing URL readability is advised only when creating a new site. Implicitly — if your site is already running, don’t engage in a URL overhaul just for this.

A poorly handled URL migration can break internal PageRank, generate 404s, and lose link juice if the 301 redirects are shaky. The risk far outweighs the hypothetical gain of having "best-running-shoes" instead of a numerical ID.

What is the actual hierarchy of ranking factors here?

Google primarily looks at internal linking, semantic context, link anchors, and page depth. The URL serves as a weak signal among dozens of others. It can reinforce thematic coherence but does not carry ranking power on its own.

A/B tests on URL migrations often reveal no significant delta in organic traffic post-migration, provided that the redirects are handled neatly. This confirms Mueller’s statement — the weight is there, but it is anecdotal.

• The URL is not a major ranking factor — its influence is minimal compared to content, backlinks, or internal linking.
• Optimizing URLs is relevant for new sites — it sets a clean foundation from the start, without the risk of breaking anything.
• On an existing site, don't change URLs without a solid reason — it's generally not worth the effort.
• The real lever is the internal linking structure — focus your efforts there instead of rewriting URLs.

Is this statement consistent with on-the-ground observations?

Yes and no. On paper, Mueller is correct — large-scale tests show that changing a URL from "/product?id=1234" to "/trail-shoes-men" does not miraculously propel the page to the top 3. The real gain is marginal.

But let's be honest: a readable URL improves click-through rate in the SERPs. A user who sees "example.com/seo-technique-guide" is more likely to click than "example.com/p?cat=12&id=456". It’s an indirect effect, not a pure algorithmic boost, but it impacts organic CTR — and that's something Google monitors [To be verified].

What nuances should be added to this advice?

Mueller says "minimal," not "zero." In ultra-competitive niches, where every micro-signal counts, a keyword-friendly URL might make the difference between position 4 and position 5. It’s negligible across 95% of sites, but not all.

Another point: the semantic consistency. If your URL contains "running-shoes" while your H1, title, and content discuss trails, you create a contradictory signal. The URL doesn’t carry ranking power, but it can harm if inconsistent.

In what cases does this rule not apply completely?

On multilingual sites or e-commerce platforms with thousands of pages, URL structure plays a role in crawl budget. A clean hierarchy helps Googlebot understand the site structure. It’s not the URL itself that boosts ranking, but it facilitates exploration — and that is critical.

If you're launching a new site, starting with a clean structure is best. If your site is 10 years old and performing well, don’t break anything for a hypothetical gain. The technical risk outweighs the SEO benefit. And that's where the problem lies — many agencies still market URL overhauls as a miracle lever. Spoiler: it’s rarely the case.

What should you concretely do with your URLs?

New site: choose a readable, short URL structure with relevant keywords. No unnecessary dynamic parameters, no session IDs, no superfluous dates. A URL like "/link-building-guide-2023" will age poorly — prefer "/link-building-guide".

Existing site: don’t change anything unless you have a solid technical reason — complete overhaul, platform migration, domain consolidation. In that case, prepare a comprehensive 301 redirect plan, test in pre-production, and monitor every step. The slightest blunder can cost you thousands of organic visits.

What mistakes should you absolutely avoid?

Never do a "cosmetic" URL migration to satisfy a client who thinks that "running-shoes" will double their traffic. Explain that the ROI is close to zero and that the technical risk is real. Instead, focus on internal linking, semantic optimization, and backlinks.

Another classic trap: thinking that a keyword-stuffed URL compensates for weak content. A page with "/best-running-shoes-men-2024-cheap-free-shipping" won’t rank better than a page with a clean URL and solid content. Google isn’t fooled. The URL is just one signal among hundreds.

How can you verify that your URL structure is optimal?

Audit your site with Screaming Frog or Oncrawl. Spot URLs that are too long (>100 characters), those with unnecessary parameters, and those that break semantic coherence. Ensure your folder structure accurately reflects your thematic hierarchy — this helps Google understand your structure.

Also, test the CTR in Search Console. If an unappealing URL drags down your CTR, it may justify a localized redesign — but only if the discrepancy is significant and you have the resources to manage the migration properly.

• Only modify the URLs of an existing site if you have a major technical reason (platform migration, complete redesign).
• On a new site, adopt a short, readable URL structure from the start, without unnecessary dynamic parameters.
• Prepare a comprehensive 301 redirect plan prior to any migration — test in pre-production, monitor server logs.
• Focus your efforts on internal linking and semantic coherence rather than solely optimizing URLs.
• Regularly audit your URLs with crawl tools to spot inconsistencies or overly complex structures.
• If you notice low organic CTR on certain pages, check if the URL is the cause before concluding there’s a content problem.
