Official statement

Webmasters cannot ask Google to crawl more. Google automatically detects server capacity and adjusts the crawl. It is only possible to limit crawling, not to increase it. Google's scheduler is smart enough to adapt.

TL;DR

Google states that webmasters cannot request an increase in the crawl budget — the scheduler automatically adjusts to detected server capacity. The only option is to limit crawling through robots.txt or Search Console settings. In practice, if your site struggles to be crawled, optimizing quality signals and internal structure remains the only viable strategy.

What you need to understand

What is crawl budget and why does Google control it?

The crawl budget refers to the number of pages that Googlebot accepts to crawl on a site within a given period. Google determines this quota based on two variables: the technical capacity of the server (response time, availability) and the perceived value of the content (freshness, quality, popularity).

Martin Splitt clarifies here that this budget cannot be negotiated upwards. Google's scheduler measures server latency in real-time and automatically adjusts the frequency of requests to avoid any overload. If your infrastructure can handle 10 requests per second without slowing down, Googlebot will exploit that margin — but you cannot ask it to increase to 20 if your server is unprepared for that.

Why does Google refuse any direct control over crawling upwards?

The reason lies in two operational constraints. First, to protect webmasters' infrastructures: excessively aggressive crawling slows down or crashes a server, degrading the user experience for real visitors. Secondly, to optimize Google's resources: Googlebot cannot crawl the entire web every day — it prioritizes sites that deserve it based on relevance signals.

In practice, this means that a recent, slow, or low-content site will never benefit from intensive crawling, even if its owner requests it. Google believes that its prioritization algorithm is smart enough to allocate crawl where it adds the most value to the index.

What is the only leeway offered to webmasters?

Google only allows limiting crawling, never speeding it up. You can block entire sections via robots.txt, restrict the crawl rate in Search Console (a method now not recommended), or use noindex to exclude pages from the index.

This asymmetry reveals a clear philosophy: Google wants to keep full control over crawl allocation, as handing it to webmasters would open the door to abuses (spam sites claiming massive crawling) and would disrupt the overall efficiency of the engine.

  • The crawl budget is automatically determined by Google based on server capacity and content value
  • No official method allows for increasing this budget — explicit requests are ignored
  • The only possible action: limit crawling through robots.txt or Search Console
  • The scheduler adjusts in real-time to avoid any server overload
  • Google prioritizes sites that demonstrate freshness, popularity, and content quality

SEO Expert opinion

Does this statement align with real-world observations?

Yes, but with an important nuance. In practice, it is indeed observed that no direct manipulation forces more frequent crawling: repeatedly submitting sitemaps, multiplying URL inspections in Search Console, or emailing Google does not change the allocated quota. [To verify]: the relationship between server speed and crawl budget is often presented as mechanical, while in reality other factors (domain authority, update frequency) play a major role that Google publicly downplays.

It is also noted that high-authority sites (media, large e-commerce) benefit from disproportionate crawling compared to their more modest competitors, even with equivalent server response times. This suggests that the site's 'merit' weighs more heavily than mere technical capacity — a point that Martin Splitt does not address here.

What are the flaws or gray areas of this rule?

The main limitation of this statement is that it oversells the intelligence of the scheduler. In reality, Googlebot sometimes goes weeks without recrawling important pages (old categories of an e-commerce site, in-stock product pages) even when the server is fast and available. If the scheduler were truly 'smart enough', such anomalies would not exist.

Moreover, Google never specifies which signals trigger a natural increase in crawling. It is empirically known that regularly publishing fresh content, obtaining quality backlinks, and generating organic traffic accelerates crawling — but these levers remain indirect and slow. A webmaster cannot thus 'unlock' inadequate crawling quickly, even by fixing all technical issues.

In what cases does this rule present a real problem?

Sites with high volumes (marketplaces, aggregators, advertisement portals) suffer most from this limitation. With hundreds of thousands of pages changing daily, a crawl budget that is too low means that critical updates never make it to the index (prices, availability, user content).

For these players, the inability to negotiate more intensive crawling amounts to suffering a structural penalty: they must compensate with heavy optimizations (reducing the number of URLs, removing unnecessary facets, consolidating content) while better-rated competitors by Google enjoy preferential treatment without particular effort.

Attention: If you notice a sudden drop in crawling without any technical changes on your part, first check the Core Web Vitals and server errors in Search Console — Google can reduce crawling in response to performance degradation, even temporarily.

Practical impact and recommendations

What should you do if crawling is insufficient?

Since asking for more crawling is futile, the only strategy is to optimize the merit signals that Google uses to prioritize. This involves three axes: regularly publishing fresh content (news, blog, new listings), improving server speed (response time ideally < 200 ms), and enhancing domain authority through quality natural backlinks.

At the same time, it is essential to reduce crawl budget waste: block unnecessary facets in robots.txt, remove duplicate or low-value pages, fix redirect loops and 404 errors. Every mistakenly crawled URL consumes a part of the quota that could have served strategic pages.

What mistakes should you absolutely avoid?

The first mistake is to massively submit URLs via the inspection tool in Search Console hoping to force a crawl. Google has confirmed that this tool is only for checking a page's indexability, not for increasing the overall crawl. When used en masse, it even triggers algorithmic suspicion and can slow down crawling instead of speeding it up.

The second pitfall: deliberately slowing down the crawl via Search Console thinking you’re 'saving' for important pages. In reality, artificially reducing the crawl rate does not redistribute the budget elsewhere — it simply decreases it. Google only reallocates if the limitation comes from a real server constraint, not manual settings.

How can I check that my site is being crawled correctly?

Analyze the crawl statistics report in Search Console: observe the number of pages crawled per day, average response times, and host errors. A stable crawl with short response times (< 300 ms) indicates that Google is not limited by your server. If crawling is low despite good technical performance, it is because Google considers your content low priority — you then need to work on quality and popularity.

Cross-reference this data with the server logs: identify the sections that Googlebot crawls most frequently and those it neglects. If strategic pages are ignored, check their accessibility (no accidental noindex), their internal linking (are they linked from the homepage or important hubs?), and their update history (a recently modified page attracts the bot more).

  • Regularly publish fresh content to signal sustained activity
  • Improve server response times (< 200 ms ideally)
  • Block facets, filters, and low-value pages in robots.txt
  • Remove duplicate or low-value content that unnecessarily consumes crawl
  • Strengthen internal linking to priority pages
  • Monitor the Search Console "Crawl Statistics" report monthly
The crawl budget remains a parameter entirely controlled by Google. The effective approach lies in optimizing site structure, server performance, and content quality to merit more intensive crawling — rather than attempting nonexistent shortcuts. These optimizations, especially on complex sites with high volumes, often require specialized expertise and regular monitoring. If you find that your site struggles to be correctly crawled despite your efforts, consulting a specialized SEO agency may be advisable to identify invisible blockages and structure a tailored optimization strategy.

❓ Frequently Asked Questions

Peut-on augmenter le crawl budget en soumettant un sitemap plus souvent ?
Non. Soumettre un sitemap informe Google des URLs à découvrir, mais n'influence pas le quota de crawl alloué. Le scheduler décide seul de la fréquence et de l'intensité du crawl.
L'outil d'inspection d'URL dans Search Console force-t-il un recrawl immédiat ?
Il déclenche un crawl ponctuel de l'URL inspectée, mais ne modifie pas le crawl budget global. Utilisé massivement, il peut même alerter Google sans bénéfice réel.
Réduire le taux de crawl dans Search Console redistribue-t-il le budget vers d'autres pages ?
Non. Limiter manuellement le crawl diminue simplement le nombre total de pages crawlées, sans réallocation automatique. Google ne redistribue que si la limitation vient du serveur lui-même.
Un serveur plus rapide augmente-t-il automatiquement le crawl budget ?
Pas directement. Un serveur rapide permet à Google de crawler plus sans risque, mais le scheduler tient aussi compte de la valeur perçue du contenu. Un site rapide mais pauvre reste peu crawlé.
Les backlinks influencent-ils le crawl budget alloué à un site ?
Oui, indirectement. Un site populaire avec de nombreux backlinks de qualité signale à Google qu'il mérite un crawl fréquent pour détecter rapidement les nouveaux contenus ou mises à jour importantes.
