Headless commerce is a way to speed up your online store by using modern technology for your website in order to boost conversions. See our full post on what headless commerce is for more info
There are many reports on how increasing performance impacts conversions
We are taking your site performance statistics as reported by Google Page Speed Insights, and finding how many more seconds it takes for your page to be visible your customer (the "first contentful paint") compared to an optimized headless site
We are using the stat that 1 tenth of a second in faster performance can boost conversions by 8% and assume you can get at least half of that (4% per 1/10 a second). Next, assuming you can conservatively get your site down to 2 seconds or less with an optimized headless build, we get the formula used to calculate the ROI above:
(load time seconds - 2) * (80 / 2)
In cases where the value of the above ROI formula are greater than 50%, there is clearly major room for optimization, so we just consider at that point the conversion improvement can vary significantly, so we consider everything in that range to be "+50%"
