I agree with Zach that the Lighthouse scores we see - shared mostly on Twitter - should be taken with a grain of salt, as they are often shared without any mention of the test conditions.

Even using Page Speed Insight - a tool that many of our less technical clients rely on heavily - should be done with caution, as scores for the same page can vary by as much as 15 points in a matter of minutes.

  1. Same page tested on PageSpeed Insights over a few hours the same day, without anything modified, and the desktop scores vary from 19 to 59… 🤷‍♂️

    A lot of businesses rely on this crap to now if their site is "fast" enough for Google SEO! 😭

    Three different scores: 44, 59, 19
