Should you really remove stop words from your URLs to boost your SEO?

Have stop words really been penalizing in the past?

For years, a strong belief circulated within the SEO community: removing stop words from URLs would enhance their relevance in Google's eyes. This logic emerged from a time when search engines analyzed URLs as direct ranking signals, with each word counting.

The reality has evolved. Modern algorithms now understand context and intent far beyond a simple lexical parsing of the URL. Stop words like 'in', 'at', 'how', or 'what' do not dilute your page's thematic relevance. They do not consume an imaginary "quota" of keywords.

Why is Google clarifying this now?

John Mueller addresses a topic that continues to fuel unnecessary debates. Many CMS generate URLs automatically from titles, including these small words. Some SEOs panic, re-structure manually, and break internal links.

Google sets a clear boundary: stop wasting time on this non-issue. URL optimization remains important, but not to the point of mutilating a readable structure to eliminate a 'the' or an 'of'. What matters is the coherence, semantic clarity, and stability of your URLs over time.

What is the real technical limit to watch for?

Mueller mentions that overly long URLs become difficult to type manually. This is a minor yet real point: a 150-character URL stuffed with stop words will be less cleanly copied and pasted in offline contexts or for quick sharing.

But let’s be honest: how many users still manually type complex URLs? Most click, copy-paste, or scan a QR code. So this isn't an SEO barrier, rather a marginal usability detail. If your URL is 80 characters instead of 60 because of a few 'in' and 'of', no one will complain.

• Stop words in URLs (in, at, how, what, of, the) do not influence ranking.
• A slightly longer URL is not a technical issue for Google.
• Readability and semantic coherence take precedence over raw length.
• No need to rewrite your existing URLs to eliminate these words.
• Focus your efforts on the overall structure and stability of your URLs.

Is this statement consistent with field observations?

Yes, and it even confirms what has been observed for several years. The sites that perform best in the SERPs are not those with ultra-compressed URLs like "/seo-url-optimization" but often those with descriptive and natural structures like "/how-to-optimize-seo-urls".

A/B tests on URL redesigns rarely show measurable gains when the only variable is the removal of stop words. However, breaking old URLs for this reason generates risks: loss of backlinks, dilution of accumulated authority, redirection errors. The risk clearly does not outweigh the reward.

What nuances should be addressed nonetheless?

Beware: this does not mean that any verbose URL is acceptable. A 200-character URL stuffed with conjunctions, adverbs, and determiners remains a problem, not directly for Google, but for user experience and social sharing. Platforms truncate, and users doubt the legitimacy of the link.

Moreover, if your CMS automatically generates URLs from long and poorly formatted titles, you end up with clunky structures like "/here-is-how-to-do-this-and-that-in-such-context-in-2025". Here, the issue isn't the stop words; it's the lack of editorial curation of your slugs. [To check]: Mueller does not specify whether excessively long URLs (150+ characters) might undergo different treatment during crawling or indexing, even though no direct ranking signal is affected.

In what cases might this rule not be sufficient?

Multilingual or multi-regional sites must remain vigilant. In some languages, stop words take up more space or create ambiguities. A French URL with "dans-le-contexte-de" will be less effective than an equivalent English version simply because relative length changes perception.

Next, if you operate in a highly competitive sector where every detail counts, keeping URLs short and impactful is still a psychological advantage for CTR in the SERP. Users scan quickly: a clear URL like "/seo-strategy" inspires more confidence than a convoluted URL, even if Google treats them technically the same way.

What should you do about your existing URLs?

Nothing, in most cases. If your current URLs contain stop words and your site is performing well, don’t change a thing. Any URL modification involves 301 redirects, a risk of losing link equity, and unnecessary technical complications.

If you’re launching a new site or a redesign, set up your CMS to generate clean slugs but without obsessive focus on stop words. Aim for clarity and coherence, not maximum compression. A URL like "/how-to-rank-in-google" is perfectly acceptable.

What mistakes should be avoided when generating URLs?

The worst mistake would be creating artificial, fragmented, unreadable URLs to eliminate every 'in' or 'of'. An example to avoid: "/rank-google-seo-tips-beginners" when "/seo-tips-for-beginners-to-rank-in-google" is more natural and comprehensible.

Another pitfall: using automated "cleaning" tools that blindly remove all stop words. You risk creating semantic ambiguities or disrupting the logical hierarchy of your site structure. Retain editorial control over your slugs, especially for strategic pages.

How can you check that your URL structure is optimal?

Analyze your main URLs with a pragmatic eye: are they descriptive, coherent, stable? If yes, you're good. If some URLs exceed 120 characters or contain incomprehensible query strings, then yes, that's an issue.

Use your preferred crawling tool to identify abnormally long or poorly formed URLs. Prioritize those with traffic or backlinks. For new pages, apply a simple rule: if you have to read the URL three times to understand what the page is about, it's poorly crafted.

• Do not modify your existing URLs solely to remove stop words.
• Configure your CMS for clear and natural slugs, without systematic removal.
• Avoid URLs longer than 120 characters unless there is a strong editorial necessity.
• Regularly audit your strategic URLs to detect structural anomalies.
• Prioritize stability: every URL change = risk of losing authority.
• Maintain editorial control over the slugs of pages with high business stakes.
