Free Page Speed Test with AI Readiness Score
This free page speed test uses real data from Google PageSpeed Insights. You get Core Web Vitals, a mobile performance score, and AI readiness signals in one report. No login required.
Why Page Speed Affects AI Search Visibility
AI crawlers, like traditional search bots, work better with fast websites. A slow page can take longer to fetch, render, and understand. That means new content may be discovered more slowly, and some pages may not be processed as completely as you expect. Speed is also a trust signal. A fast site usually feels more professional, more stable, and more reliable to users. Those same qualities help crawlers too. When a page loads quickly and stays stable, it is easier for both people and machines to read the main content without waiting for layout jumps or delayed scripts. Poor speed scores can also hint at deeper technical problems, such as oversized images, slow hosting, or scripts that block content from loading quickly. Improving page speed helps your users immediately, and it also supports better crawling, indexing, and AI readiness.
What Are Core Web Vitals?
LCP, Largest Contentful Paint: Measures how long it takes for the main visible content on the page to appear. A good score is under 2.5 seconds, and a poor score is over 4 seconds.
CLS, Cumulative Layout Shift: Measures how much the page jumps around while loading. A good score is under 0.1. If buttons and text move while the page loads, users notice it.
INP, Interaction to Next Paint: Measures how quickly the page responds when someone clicks, taps, or types. A good score is under 200 milliseconds.
FCP, First Contentful Paint: Measures how long it takes before the first visible element appears on screen. A good score is under 1.8 seconds.
These metrics matter because they describe the real loading experience, not just a technical benchmark. If the main content appears late, users bounce. If the layout jumps, users lose trust. If the page reacts slowly, people assume the site is broken. AI systems may not feel frustration the way people do, but they still benefit from pages that render clearly and predictably.
How Our Speed Test Works
We call Google's PageSpeed Insights API directly and return the real performance data for your URL. That means the scores and metrics come from the same source used by Google's own PageSpeed tool. We focus on mobile performance because most users browse on phones and because mobile conditions are tougher. Desktop scores are often higher, but mobile is where speed problems are more visible and more costly. In the full report, speed appears alongside the rest of your AI readiness signals so you can see the bigger picture.
How to Improve Page Speed
Compress large images and use modern formats such as WebP so the browser downloads less data.
Remove or delay heavy scripts that are not needed right away, especially third-party tools and large tracking tags.
Use faster hosting and caching so your server starts sending the page quickly instead of making users wait.
Reserve space for images, videos, and embeds so the page does not jump while content is loading.
These are usually the fastest wins for small businesses and content sites. You do not need a perfect score to see benefits. Even a moderate improvement in image size, script loading, and server response time can make a page feel much faster. That often improves both conversion and crawl quality at the same time.
FAQs for Free Page Speed Checker
Does page speed affect AI search visibility?
Page speed affects crawl efficiency and user experience, and both influence whether a page is chosen as a reliable source. Slow pages can time out, load partial content, or produce poor engagement signals. Faster pages are easier for AI systems to fetch and interpret consistently.
What is a good Google PageSpeed score?
In general, 90+ is considered fast, 50-89 needs improvement, and below 50 is slow. Scores can vary by device and network conditions, so focus on consistent improvements. Core Web Vitals metrics often matter more than the single score.
What are Core Web Vitals and why do they matter?
Core Web Vitals are real-world metrics that describe loading speed and stability. LCP measures when the main content appears, CLS measures visual stability, and INP measures responsiveness. Better vitals improve usability and reduce the chance crawlers see a broken or incomplete page.
How is this speed test different from Google PageSpeed Insights?
We use Google PageSpeed Insights data directly, but we combine it with AI readiness checks in the same report. That means you see speed metrics alongside AEO, GEO, crawler access, content, and technical signals. It is designed to help you prioritize speed fixes that support AI visibility.
What is LCP and how do I improve it?
LCP is Largest Contentful Paint, which measures when the largest visible content element loads. You can improve it by optimizing images, reducing server response time, avoiding heavy render-blocking scripts, and using efficient caching. Faster LCP helps both users and crawlers get the full page sooner.
