Server Response Time: What It Is & Why It Matters for SEO
Server response time, also known as Time to First Byte (TTFB), measures how long it takes for a server to start delivering data upon receiving a client request. A fast response time is essential—Google recommends keeping TTFB under 200 milliseconds. Why? Because faster sites rank better, engage more, and convert higher. A slow server makes your entire site feel sluggish, no matter how well your frontend is optimized.

Google’s Page Experience signals consider site speed. A faster server contributes directly to better Core Web Vitals and higher rankings.
Fast server response means quicker site loading, lower bounce rates, and higher time on page—key UX metrics that influence SEO outcomes.
Mobile users expect near-instant loading. A slow server on mobile = lost traffic and revenue. Smartphone users are less patient than ever.

Frequently Asked Questions
What is a good server response time?
A good server response time is under 200ms. Anything above 500ms can negatively impact SEO, user experience, and bounce rates.
How does server response time affect SEO?
Google factors page speed into search rankings. A slower server increases load time, weakening Core Web Vitals scores and decreasing visibility.
What causes slow server response time?
Common causes include overloaded servers, poor hosting, unoptimized databases, excessive plugins, or poorly coded backend scripts.
How can I check my server response time?
Dedicated hosting generally provides faster and more consistent server response times, while shared hosting can suffer under load from other users.
Shared hosting vs. dedicated hosting: which is better for response time?
Yes. A Content Delivery Network (CDN) reduces latency by serving content from the closest data center to the user, improving perceived and actual speed.
