The Lighthouse scoring distribution is a log normal distribution that is derived from the performance metrics of real website performance data (see sample distribution [here](https://www.desmos.com/calculator/zrjq6v1ihi)). Once we finish computing the percentile equivalent of your raw performance score, we take the weighted average of all the performance metrics (per the weighting above). Finally, we apply a coloring to the score (green, orange, and red) depending on what "bucket" your score falls in. This maps to: -- Red (poor score): 0-44. -- Orange (average): 45-74 -- Green (good): 75-100. +- Red (poor score): 0-49 +- Orange (average): 50-89 +- Green (good): 90-100 ### What can developers do to improve their performance score? *Note: we've built [a little calculator](https://docs.google.com/spreadsheets/d/1Cxzhy5ecqJCucdf1M0iOzM8mIxNc7mmx107o5nj38Eo/edit#gid=283330180) that can help you understand what thresholds you should be aiming for achieving a certain Lighthouse performance score. * diff --git a/lighthouse-core/report/html/templates.html b/lighthouse-core/report/html/templates.html index fb92d7ce9286..29e93cb1131b 100644 --- a/lighthouse-core/report/html/templates.html +++ b/lighthouse-core/report/html/templates.html @@ -27,9 +27,9 @@
