One of the longest-standing items on my performance monitoring tool wishlist is an automatically-generated performance improvement checklist, with the improvements ordered by the impact that they will have on the website. In a previous life, I spent countless hours writing performance reports and conducting A/B performance tests to figure out which change would have the biggest impact on a website's performance.
So I'm understandably very excited that today we're announcing the new Improve dashboard – a prioritised performance improvement checklist that aggregates Lighthouse and Google PageSpeed results across all the URLs in your site to identify the most impactful performance changes you can make.
In the year since Google rolled out Lighthouse, it's safe to say that "Will you be adding Lighthouse scoring?" is one the most common questions we've fielded here at SpeedCurve HQ. And since Google cranked up the pressure on sites to deliver better mobile performance (or suffer the SEO consequences) earlier this month, we've been getting that question even more often.
We take a rigorous approach to adding new metrics. We think the best solution is always to give you the right data, not just more data. So we're very happy to announce that after much analysis and consideration, we've added Lighthouse scores to SpeedCurve. Here's why – as well as how you can see your scores if you're already a SpeedCurve user.
