What are Core Web Vitals?

Web Vitals is an initiative by Google to provide unified guidance for quality signals that are essential to delivering a great user experience on the web.

Optimizing for quality of user experience is key to the long-term success of any site on the web. Whether you're a business owner, marketer, or developer, Web Vitals can help you quantify the experience of your site and identify opportunities to improve.

Should I run Lighthouse audits multiple times?

What's the maximum number of pages that can be compared?

The maximum number of pages that can be compared with each other is limited to 12 pages to still ensure good readability in all graphs.
