Why does Google always say 'it depends' when you ask SEO questions?

Why does Google refuse to provide clear answers in SEO?

This statement is a classic line of defense. Google avoids committing to absolute rules because its algorithm combines hundreds of signals that interact differently depending on the context. A 50-page site does not face the same challenges as an e-commerce platform with 100,000 URLs.

The problem? This institutional caution prevents obtaining actionable recommendations. A practitioner asking "Is an XML sitemap necessary for a 200-page site?" deserves a more precise answer than "it depends". However, Google prefers to play it safe rather than take a clear stance that could be contradicted by an exceptional case.

What factors really influence these variations in response?

The size of the site is often mentioned, but that’s an oversimplification. What matters is the available crawl capacity, the frequency of content updates, the depth of the structure, and the quality of backlinks. A small site with a terrible internal linking structure can encounter the same obstacles as a poorly optimized large site.

The industry also plays a role. A news site requires indexing responsiveness that a corporate showcase site does not demand. The ranking algorithms adjust their weights based on whether you are in YMYL, e-commerce, informational content, or local. However, Google never publishes these specific weights per vertical — so we are left to test blindly.

Is this contextual approach really technically justified?

Yes and no. Technically, it is true that Google cannot apply the same crawl budget rules to a 500-page site as it does to Amazon. But some questions have universal answers that could be documented without ambiguity: the canonical tag works the same way everywhere, and the nofollow attribute does as well.

The "it depends" has become a convenient excuse to avoid finely documenting thresholds and exceptions. For example, Google could say, "on sites with fewer than 5,000 pages, the XML sitemap has a marginal impact if the internal linking is coherent." But that will never come — too risky to commit to specific figures.

• Context really matters: size, industry, history, quality of linking and backlinks influence recommendations.
• Google uses this caution to never commit to numbered thresholds or absolute rules.
• Some questions deserve clear answers but Google prefers to remain vague to legally and technically cover itself.
• Practitioners must test and measure on each project rather than waiting for a universal guide.
• This stance reinforces the information asymmetry between Google and SEOs, who navigate blindly without a stable reference.

Is this statement consistent with observed practices in the field?

Absolutely. For the past fifteen years, Google's official responses have oscillated between vague and contradictory. When John Mueller or Gary Illyes answer a specific question, they invariably start with "it depends". It has become a meme in the industry, and this statement formalizes a position we already know.

But let’s be honest — some parameters do not depend on context. Page load speed improves UX everywhere. Duplicate content is problematic regardless of the site size. The schema.org markup operates according to standardized specs. When Google refuses to take a stance on these points, it is out of legal precaution, not technical rigor.

What nuances should be added to this claim?

There are two types of "it depends". The first is legitimate: optimizing the crawl budget makes no sense on a well-structured blog of 300 articles. The second is an escape: when asked whether the bounce rate is a ranking signal, the answer "it depends" mainly masks the fact that Google does not want to detail the behavioral signals it uses.

An expert must distinguish between questions where context genuinely changes the technical answer and those where Google hides behind this phrase to avoid revealing internal mechanisms. When a client asks whether their site with 2,000 products needs a sitemap, the answer is yes, unequivocally. The "it depends" does not add value here. [To be verified]: Google has never published a documented threshold to determine when a sitemap becomes critical, while it could easily do so.

In what cases does this rule not apply?

There are SEO invariants that do not change with context. HTML structure must be valid. URLs must be crawlable. Title tags and meta descriptions must exist. HTTPS is mandatory to avoid browser alerts. These rules are binary — there is no acceptable "it depends".

The problem arises when Google applies this formula to questions that deserve clear recommendations. For example, a practitioner asks: "Should internal search pages be blocked in robots.txt?" The answer should be "yes, unless they provide unique value to users." But Google will prefer to say "it depends on your architecture" to avoid taking a stance that a counterexample could contradict.

How can we translate this 'it depends' into a concrete action plan?

First step: map the invariants. For each project, identify what is non-negotiable — HTTPS, clean HTML structure, XML sitemap for all sites with more than 500 pages, consistent canonical tags, mastered robots.txt. These foundations do not depend on anything; they apply everywhere.

Next, list the contextual optimizations: crawl budget if +10,000 URLs, optimization of Core Web Vitals for heavy sites, internal linking if excessive depth, fresh content if timely or e-commerce. On these points, "it depends" is legitimate — you must analyze your specific case, test, and measure in Search Console and GA4.

What mistakes should be avoided in the face of this official ambiguity?

Don’t fall into decision paralysis. Some SEOs wait for Google confirmation before acting, which leads to inaction. If an optimization improves UX, accessibility, or clarity for Googlebot, implement it — even without official validation. The "it depends" is not an excuse for inaction.

The second trap: over-contextualizing simple rules. For example, some still debate the utility of XML sitemaps on small sites. If your site has over 100 pages and an imperfect internal linking structure, generate a sitemap — end of story. The context does not change the basic good practice; it only refines the priority.

How to ensure that my site adheres to best practices despite this uncertainty?

Use Search Console as your truth reference. If your strategic pages are indexed quickly, if the coverage rate is consistent, if the Core Web Vitals are good — then your choices are validated by the ground, regardless of what Google says. It’s the only reliable measure in an environment where official recommendations remain vague.

Establish structured A/B tests whenever possible: modify a segment of your site, compare performances with a control group, measure the impact on crawl, indexing, and ranking. This empirical approach compensates for the absence of precise guidelines. If an optimization works in your context, document it and replicate it — it’s more reliable than a vague statement from Google.

• Identify SEO invariants (HTTPS, sitemap, HTML structure, canonical) and apply them systematically
• List contextual optimizations (crawl budget, CWV, linking) and prioritize them according to your specific case
• Never wait for a Google official confirmation before acting if the optimization improves UX or crawlability
• Use Search Console as a validation reference rather than public statements
• Implement A/B tests to measure the actual impact of optimizations in your context
• Document the observed results to build your own repository of validated best practices
