How is this different to Lighthouse?
Lighthouse is great - we love it. But it works by running one test, and tells you what your site speed metrics look like for just that one data point.
In reality your visitors will be on different devices, screen sizes, different connection speeds, in different locations - and will be seeing different site speeds as a result. One data point won't give you the full story when you have hundreds of thousands of visitors.
Blackbird tracks the site speed metrics for all of your visitors - down to the millisecond - so you'll have a much clearer picture of how fast your site really is.
How does it work?
You also need to add a small piece of code on your Thank You page so that it can register that a user has converted, and what the order value was. This let's Blackbird tell you if faster visits have a better conversion rate, and tell you how much extra revenue could be made from making site speed improvements.
