Speed performance
When a user opens a page of your website, there is a certain amount of loading time spent by the browser to show it fully.
This happens due to various reasons, each one monitored by a specific parameter.
The Max Potential First Input Delay finds the slowest case of First Input Delay in the page: what is measured is the timeframe between the first interaction of a user with the page (for example when there is a click on a link) and the browser's response to that input.
Max Potential First Input Delay is calculated by SeoChecker in milliseconds, monitoring the longest task after the completion of the First Contentful Paint (it is impossible to interact with a page if there is nothing displayed).
The score is assigned according to a ratio between the Max Potential FID of your page and the Max Potential FID data of a big archive of other websites (HTTP Archive).
