I optimize site performance for a living. Now trying to understand how it relates to AI search.

My questions:

  • Does page speed actually impact AI citations?
  • Are Core Web Vitals relevant for AI?
  • Is speed a ranking factor or just a baseline requirement?

Looking for data, not assumptions. What does the research show?

We analyzed speed metrics across 100,000+ pages. Here’s what the data shows:

Speed correlation with AI citations:

Speed MetricFastMediumSlow
FCP < 0.4s6.7 citations--
FCP 0.4-1.0s-4.2 citations-
FCP > 1.13s--2.1 citations

3x difference between fastest and slowest sites.

But here’s the nuance: Correlation doesn’t prove causation.

Possible explanations:

  1. AI bots timeout on slow pages
  2. Fast sites = better maintained = better content
  3. Speed is a quality proxy signal
  4. Well-funded sites are both fast and have good content

What we can confidently say:

  • Very slow sites get fewer citations
  • Speed threshold matters more than marginal gains
  • Content quality still trumps speed

The threshold insight is interesting. What’s the minimum speed to not lose citations?

Speed thresholds for AI visibility:

MetricDanger ZoneSafe ZoneOptimal
TTFB> 2s< 1s< 0.5s
FCP> 1.5s< 1s< 0.5s
LCP> 2.5s< 2s< 1.5s

TTFB matters most for AI bots: They’re making HTTP requests. If your server doesn’t respond quickly, they may timeout or move on.

Practical advice:

  • Target TTFB under 500ms
  • FCP under 1s is safe
  • After that, focus on content quality

Diminishing returns: Going from 2s to 1s: Big improvement Going from 0.5s to 0.3s: Marginal benefit

Don’t obsess over perfect scores. Just don’t be slow.

How AI crawlers actually behave with slow pages:

What we see in logs:

  1. Initial request - Bot requests page
  2. Wait for response - Timeout if too slow
  3. Parse HTML - Only what’s returned
  4. Move on - Crawl budget applied

Timeout patterns: Different bots have different patience:

  • GPTBot: Fairly patient (~5-10s)
  • PerplexityBot: Less patient (~3-5s)
  • Varies by implementation

What happens with slow pages:

  • Sometimes partial content received
  • Sometimes timeout before response
  • Retry logic varies

Real impact: A page that takes 5s might be crawled 30% less often than one taking 0.5s.

Less crawling = Less chance of being in training data = Less likely to be cited.

Speed affects crawl success, which affects AI visibility indirectly.

Speed vs. content quality analysis:

Our experiment: Compared pairs of pages on same topics:

  • Fast page with thin content
  • Slower page with excellent content

Results: The slower page with better content got more citations in every case.

The hierarchy:

  1. Content quality (most important)
  2. Authority signals
  3. Content structure
  4. Technical factors including speed

What this means: Speed is necessary but not sufficient.

A fast page with poor content won’t outrank a slightly slower page with excellent content.

But: A slow page with great content loses to a fast page with equally great content.

Practical advice: Meet speed thresholds. Then focus entirely on content.

Interesting data point from CDN perspective:

AI bot behavior we observe:

  • GPTBot and PerplexityBot make millions of requests daily
  • They don’t retry failed requests as aggressively as Googlebot
  • They prefer cached/fast responses

What helps:

  • CDN for edge caching
  • Prerendering for dynamic content
  • Static content where possible

What we’ve seen: Sites using our edge caching have higher AI bot success rates (95%+) vs sites serving from origin only (80-85%).

The implication: AI bots want fast, successful responses. CDN + caching helps ensure they get content reliably.

Technical infrastructure matters for AI crawl success.

Interesting counterintuitive finding:

From the research: Pages with the FASTEST Interaction to Next Paint (INP < 0.4s) actually had FEWER citations (1.6 avg) than moderate INP (0.8-1.0s, 4.5 avg).

Possible explanation: Extremely simple/static pages may lack the depth AI looks for.

Fast simple page = less content = fewer citations Moderate page = more features but more content = more citations

The lesson: Don’t sacrifice content depth for speed. A slightly slower comprehensive page beats a lightning-fast thin page.

Balance is key.

Practical speed optimization for AI visibility:

Priority 1: Server response time

  • TTFB under 500ms
  • This affects crawl success
  • CDN and caching help

Priority 2: Content delivery

  • Main content loads quickly
  • Critical content above the fold
  • Don’t lazy-load essential text

Priority 3: Avoid blockers

  • No render-blocking resources
  • Minimal third-party scripts
  • Efficient CSS delivery

What NOT to worry about:

  • Perfect Lighthouse scores
  • INP optimization (for AI specifically)
  • Millisecond improvements

The formula: Fast enough to be crawled reliably + Great content = AI visibility

How to measure if speed is affecting your AI visibility:

Track these together:

  1. Your page speed metrics
  2. AI crawler success rate (from logs)
  3. AI citation frequency

Look for patterns:

  • Do faster pages get more citations?
  • Are slow pages being crawled less?
  • What’s your crawl success rate?

Server log analysis: Check for AI bot requests and response codes:

  • 200 = Success
  • 408/504 = Timeout (speed issue)
  • 500+ = Server errors

High timeout rate = speed is hurting you.

Action threshold: If > 5% of AI bot requests timeout, speed optimization should be priority.

If < 1% timeout, speed is fine - focus on content.

Great data here. My takeaways:

Speed matters, but not infinitely:

  • Clear correlation exists
  • Threshold effects are real
  • After baseline met, diminishing returns

Practical targets:

  • TTFB: < 500ms
  • FCP: < 1s
  • Don’t sacrifice content for speed

Priority order for AI:

  1. Content quality
  2. Authority signals
  3. Structure
  4. Speed (meet threshold)

What we’re implementing:

  1. Audit for timeout issues in bot logs
  2. Ensure all content pages meet speed thresholds
  3. CDN/caching for reliable delivery
  4. Then focus efforts on content quality

Key insight: Speed is a baseline requirement, not a competitive advantage. Meet the threshold, then focus on what actually differentiates: content quality.

Frequently Asked Questions

A velocidade da página afeta a visibilidade em buscas por IA?
Pesquisas mostram correlação entre velocidade da página e citações por IA. Páginas com First Contentful Paint rápido (menos de 0,4s) tiveram média de 6,7 citações, enquanto páginas lentas (acima de 1,13s) tiveram apenas 2,1. Contudo, pode ser correlação e não causalidade direta.
Por que páginas rápidas recebem mais citações por IA?
Algumas possíveis razões: bots de IA podem dar timeout em páginas lentas, sites rápidos tendem a ser bem mantidos e com conteúdo de qualidade, ou a velocidade pode ser um dos muitos sinais de qualidade. A causalidade não está provada, mas a correlação existe.
Quais métricas de velocidade importam para rastreadores de IA?
Time to First Byte (TTFB) é o que mais importa para rastreadores - determina quão rápido eles recebem o conteúdo. Bots de IA não esperam por servidores lentos. Mire em TTFB abaixo de 500ms para garantir sucesso no rastreamento.
Devo priorizar velocidade para visibilidade em IA?
Velocidade deve ser requisito básico, não vantagem competitiva. Evite ser lento (mire abaixo de 2s de TTFB), mas além desse limite, a qualidade do conteúdo importa mais do que melhorias incrementais de velocidade.
