What is a good Page Speed Score?

A good Page Speed Score is 90-100 (excellent), 70-89 is considered good, 50-69 needs optimization, and below 50 is critical. These scores are based on Lighthouse metrics and indicate how fast your pages load and become interactive.

How does page speed affect AI search visibility?

Fast-loading pages are crawled more frequently by AI systems and are prioritized for inclusion in AI-generated answers. AI platforms favor content that provides good user experiences, and page speed is a key indicator of that experience.

What is TTFB and why does it matter?

TTFB (Time to First Byte) measures how long it takes for the browser to receive the first byte of data from your server. A good TTFB is under 200ms. It's critical because it indicates server responsiveness and affects all subsequent loading metrics.

How can I quickly improve my page speed?

Quick wins include: enabling GZIP compression, optimizing images to under 100KB each, minifying CSS/JS/HTML, enabling browser caching, removing unused code, and deferring non-critical JavaScript. These changes can often improve scores by 20-30 points.

What's the difference between Page Speed and Core Web Vitals?

Page Speed Score encompasses multiple performance metrics including TTFB, FCP, Speed Index, and TTI. Core Web Vitals specifically focuses on three metrics: LCP (loading), INP (interactivity), and CLS (visual stability). Both are important for AI search visibility.

Why Page Speed Matters for AI Search

Page Speed Score measures how quickly your pages load and become interactive—a critical factor for both user experience and AI crawler efficiency.

The Speed Advantage: Studies show that a 1-second improvement in page load time can increase conversions by 7%. For AI search, faster pages mean more frequent crawls and higher content freshness scores.
