Identify, compare, analyze and fix your Core Web Vitals scores to boost web performance of your sites. These tools will help you to do just that.
The success of your website depends on the impression it leaves on its users. By optimizing your Core Web Vitals scores, you can gauge and improve user experience. Essentially, a web vital is a quality standard for UX and web performance set by Google. Each web vital represents a discrete aspect of a user’s experience. It can be measured based on real data from users visiting your sites (field metric) or in a lab environment (lab metric).
In fact, several user-centric metrics are used to quantify web vitals. They keep evoling, too: as there were conversations around slowly adding accessibility and responsiveness as web vitals as well. In fact, Core Web Vitals are just a part of this large set of vitals.
It’s worth mentioning that good Core Web Vitals scores don’t necessarily mean that your website scores in high 90s on Lighthouse. You might have a pretty suboptimal Lighthouse score while having green Core Web Vitals scores. Ultimately, for now it seems that it’s only the latter that contribute to SEO ranking — both on mobile and on desktop.
While most of the tools covered below only rely on field metrics, others use a mix of both field and lab metrics.
PageSpeed Compare is a page speed evaluation and benchmarking tool. It measures the web performance of a single page using Google PageSpeed Insights. It can also compare the performance of multiple pages of your site or those of your competitors’ websites. It evaluates lab metrics, field metrics, page resources, DOM size, CPU time, and potential savings for a website. PageSpeed Compare measures vitals like FCP, LCP, FID, CLS, and others using land and field data.
PageSpeed Compare provides web performance reports in a dashboard-alike overview with a set of graphs. You can compare up to 12 pages at once and presents the report in a simple and readable way since it uses PageSpeed Insights to generate reports. Network and CPU are throttled for lab data tests for more realistic conditions.
Bulk Core Web Vitals Check
Experte’s Bulk Core Web Vitals Check is a free tool that crawls up to 500 pages of the entire domain and provides an overview of the Core Web Vitals scores for them. Once the tool has crawled all the pages, it starts performing a Core Web Vitals check for each page and returns the results in a table. Running the test takes a while, as each web page test is done one at a time. So it’s a good idea to let it run for 15-30 mins to get your results.
What’s the benefit then? As a result, you get a full overview of the pages that perform best, and pages that perform worst — and can compare the values over time. Under the hood, the tool uses Pagespeed Insights to measure Core Web Vitals.
You can export the results as a CSV file for Excel, Google Sheets or Apple Pages. The table format in which the results are returned makes it easy to compare web vitals across different pages. The tests can be run for both mobile and desktop.
Alternatively, you can also check David Gossage’s article on How to review Core Web Vitals scores in bulk, in which he shares the scripts and how to get an API key to run the script manually without any external tools or services.
