Checkson Check for monitoring the speed and best practices of a website

This check uses Google's PageSpeed API (which in turn is built on Lighthouse). Occasional calls to this API (e.g. few minutes) are allowed without an API key.

To determine the threshold, it's a good idea to go to pagespeed.web.dev and analyze your website initially as a baseline. Based on the percentages from the report, choose a value between 0.0 (0%) and 1.0 (100%) for the SCORE_THRESHOLD.
