Google has recently announced that it has consolidated its website speed testing tools and that PageSpeed Insights now uses Lighthouse as its analysis engine. The Lighthouse scoring sets higher standards, specifically with regard to real-world performance and users’ perception of site loading time. As part of Camilyo's ongoing commitment to leading the way in user experience, we embrace this update, and we are already hard at work on implementing the required optimizations to all Camilyo sites, existing and future.

Below you will find a brief overview of the page speed analysis changes. We are moving full speed ahead with the optimization of our platform, and will keep you posted on our progress shortly.

So, what has changed?

The previous version of Google’s PageSpeed Insights focused mainly on web development best practices metrics. What it was missing, however, was the users’ perception of speed; the actual, real-world experience with the webpage across different devices and under different network conditions, and the time it took until they could interact with the page.

The new PageSpeed Insights, powered by Lighthouse, simulates the page load on a real-world mobile network. It emphasizes user-centric performance and measures how fast meaningful content is served to site visitors and how fast they can start interacting with the page – click buttons, fill out forms, etc.

Quick overview of the main Google PageSpeed metrics

Field data
Google is gathering real users’ data for popular URLs. If there is enough data for the URL, PageSpeed will present the statistics of users’ experiences – the rate of fast, average and slow page loads out of all recorded page loads.

Lab data

First Contentful Paint
Measured in seconds, the First Contentful Paint metric marks the time it takes for the first content (text, image, background) to be displayed on the page.

First Meaningful Paint
Depending on the content (e.g., blog, Ecommerce, landing page), the First Meaningful Paint metric measures the time it takes to see the primary content, or layout objects, above the fold. Titles, texts and significant images would count as meaningful, while headers, menu items and loading spinners would not.

Speed Index
Based on the Web Page Test tool, originally developed by AOL, the Speed Index metric measures the average time at which visible parts of the page are displayed. To do that, the tool follows paint events through the developer tools timeline or, alternatively, captures the loading of the page in video.

First CPU Idle
The First CPU Idle marks the time at which the page is minimally interactive. Meaning, the window is mostly quiet, most of the UI elements are present and interactive and most user inputs can be processed in reasonable time.

Time to Interactive
Completing the First CPU Idle, the Time to Interactive metric marks the time it takes the page to become fully interactive. That is, the page displays the first contenful paint and the page responds to user interactions within 50 milliseconds.

Estimated Input Latency
The Estimated Input Latency metric measures how long it takes your page to respond to user inputs (e.g., clicks, taps or scrolls) while loading. Any response time longer than 0.5 of a second might be perceived by users as clunky and irresponsive.

As you can see, Google’s new metrics reflect users’ real-world experience and expectations by focusing on time, rather than functionality, as the key indicator for site performance. Understanding the implications of these new metrics and driven by the same user-focused approach, we at Camilyo work to optimize our sites for speed. We are taking the required measures to ensure all Camilyo sites achieve a high PageSpeed score across platforms and deliver an engaging and satisfactory experience to their users.
