I've been sharing charts of Core Web Vitals passing platforms recently, so here's the shared source of truth for the way websites are both built and experienced.
And it's called the Core Web Vitals Technology Report.
Core Web Vitals Technology Report
The Core Web Vitals Technology Report is the merger of two datasets:
- Chrome User Experience Report (CrUX);
- HTTP Archive.
HTTP Archive
You might already be familiar with CrUX, as that's where Core Web Vitals data is being collected.
Additionally, you might have seen claims such as:
- loading time on mobile devices has grown over time;
- amount of kilobytes shipped grew over time, as we can see in the chart below.
These claims typically are supported by also using data from HTTP Archive. And HTTP Archive is tracking even more data and characteristics. For example, a platform a website or webshop is running on. Or insights per framework that is being used. Or in general: the used techology.
Meet the Technology Report
That's where the Technology Report comes in. With Rick Viscomi as one of the contributors, it's actually a pre-fabricated Google Data Studio dashboard.
The dashboard tracks performance over time on the key Core Web Vitals (CWV) metrics of Largest Contentful Paint (LCP), First Input Delay (FID), and Cumulative Layout Shift (CLS). It also tracks the aggregate metric when a website passes all three of those metrics concurrently.
Why do we need a Technology Report
Good user experience is key to performing well with Core Web Vitals. And Core Web Vitals might have gotten traction within your team already, given the fact Core Web Vitals became a ranking factor.
The fun part: Core Web Vitals data is publicly available. Before, we had to use tools like Search Console and PageSpeed Insights to get data on how your site or shop was performing.
This dashboard was developed for the web community to have a shared source of truth for the way websites are both built and experienced

But with this data, we can now make a somehow informed decision from a pagespeed or just technical UX perspective before choosing or migrating to another platform. For example, amongst the selected platforms, when it comes to Core Web Vitals, Shopware is doing very good compared to other selected e-commerce platforms.
The above is depicting monthly mobile aggregated origin summary data from January 2020 to October 2021 data.
Technology Report to compare platforms
The Core Web Vitals Technology Report can tell you what percentage of websites built with a platform like WordPress passes the CWV assessment. But you can also zoom into metric specific data using the Technology Drilldown tab instead of Technology Comparison tab.
Lighthouse and Core Web Vitals
But what about pagespeed expectations when you're already in the middle of a migration to your new platform? Then be aware of the fact the Technology Report will also show you a chart with Lighthouse scores of the selected platforms you choose to select. This way, you could draw a guarded conclusion what the relation will be between the Lighthouse score and the chance of passing Core Web Vitals.
You could then get a hang of the potentially expected difference between the two. And maybe how stressed you should be in the current stage of migration or development. More so important as your Lighthouse score won't impact SEO. Core Web Vitals actually is able to impact your ranking, but moreover: your bounce rate, user happiness and conversion rate as well.
