Why website speed matters for SEO in 2026

Google uses Core Web Vitals as a confirmed ranking factor. Sites that load faster rank higher, retain more visitors, and convert at a higher rate. Our free website speed test gives you the same data as Google PageSpeed Insights — powered by AI analysis.

What does this website speed test measure?

This tool analyses the key performance metrics that Google's Lighthouse and Core Web Vitals framework use to evaluate your pages:

LCP (Largest Contentful Paint) — How fast your main content loads. Target: under 2.5 seconds.

FCP (First Contentful Paint) — When the first content appears on screen. Target: under 1.8 seconds.

TBT (Total Blocking Time) — How long your page is unresponsive to user input. Target: under 200 ms.

CLS (Cumulative Layout Shift) — How much your page layout jumps around. Target: under 0.1.

TTI (Time to Interactive) — When your page becomes fully interactive. Target: under 3.8 seconds.

Frequently Asked Questions

What is a good PageSpeed Insights score?
Google rates 90–100 as Good (green), 50–89 as Needs Improvement (amber), and 0–49 as Poor (red). Aim for 90+ on desktop and 70+ on mobile for strong SEO performance.
Does page speed directly affect Google rankings?
Yes. Since Google's Page Experience update, Core Web Vitals are a confirmed ranking signal. Faster pages also have lower bounce rates, higher dwell time, and better conversion rates — all of which indirectly improve SEO.
What is AEO (Answer Engine Optimisation)?
AEO optimises your content and technical setup so AI engines like ChatGPT, Google AI Overviews, and Perplexity cite your brand when answering user queries. It requires fast page speed, structured data, and authoritative content — all areas Sonder Digital specialises in.
How is this different from Google PageSpeed Insights?
Google PageSpeed Insights runs real Lighthouse audits in Google's infrastructure. This tool uses AI to estimate performance based on known site characteristics and provides the same categories of recommendations — ideal for quick benchmarking and identifying priority areas before a full audit.
