Time to First Byte (TTFB) Benchmarks by Industry

Time to First Byte (TTFB) measures the duration between the browser sending a request and receiving the first byte of the response. While not an official Core Web Vital, TTFB directly impacts LCP and overall page speed. Google recommends a TTFB of 800 milliseconds or less, with top-performing sites targeting under 200ms.

TTFB as a Leading Indicator

TTFB reflects your server infrastructure, database query efficiency, and caching strategy. A slow TTFB creates a cascade effect — if the server takes 1.2 seconds to respond, achieving a 2.5-second LCP becomes nearly impossible. For this reason, TTFB optimization is often the highest-leverage performance improvement a team can make.

In 2026, the gap between sites using modern edge architectures and those relying on traditional origin servers has widened considerably. CDN-first approaches, edge rendering, and serverless functions have made sub-200ms TTFB achievable for any site willing to invest in infrastructure modernization.

Industry Analysis

E-commerce sites show a wide TTFB spread, with a median of 650ms. Dynamic product pages, personalization logic, and database-heavy category pages drive slower server response times. Top performers leverage edge caching with stale-while-revalidate patterns to serve personalized content at CDN speeds.

SaaS marketing sites perform well at 450ms median. Static marketing pages are easily cacheable, but authenticated dashboard pages often have higher TTFB due to session validation and data fetching.

Media sites have the slowest TTFB at 750ms median. CMS-driven pages with complex template rendering, ad server integrations, and real-time content assembly slow down initial responses.

Healthcare sites sit at 600ms median, often constrained by legacy infrastructure and compliance-related processing that adds latency to each request.

Finance sites lead at 400ms median, benefiting from significant infrastructure investment and strict performance SLAs that drive optimization efforts.

Lowering Your TTFB

The most effective TTFB optimizations include implementing a CDN with full-page caching, optimizing database queries and adding proper indexes, using connection pooling to reduce database overhead, enabling HTTP/2 or HTTP/3 for faster connection establishment, and moving compute closer to users with edge functions. For dynamic content, consider stale-while-revalidate caching strategies that serve cached responses while regenerating content in the background.

Auditite measures TTFB for every page on your site and tracks trends over time, alerting you when server response times degrade so you can investigate infrastructure issues before they impact rankings.
