Passes Core Web Vitals
The percentage of origins passing all three Core Web Vitals (LCP, INP, CLS) with a "good" experience. Note that if an origin is missing INP data, it's assessed based on the performance of the remaining metrics. Also note that prior to March 2024, this metric used FID instead of INP.
Good First Contentful Paint
The percentage of origins with "good" FCP experiences, less than or equal to 1.8 seconds.
Poor First Contentful Paint
The percentage of origins with "poor" FCP experiences, greater than 3 seconds.
Good Largest Contentful Paint
The percentage of origins with "good" LCP experiences, less than or equal to 2.5 seconds.
Poor Largest Contentful Paint
The percentage of origins with "poor" LCP experiences, greater than 4.0 seconds.
Good Cumulative Layout Shift
The percentage of origins with "good" CLS experiences, less and or equal to 0.1.
Poor Cumulative Layout Shift
The percentage of origins with "poor" CLS experiences, greater than 0.25.
Good Interaction to Next Paint
The percentage of origins with "good" INP experiences, less than or equal to 200 ms. See Interaction to Next Paint (INP).
Poor Interaction to Next Paint
The percentage of origins with "poor" INP experiences, greater than 500 ms. See Interaction to Next Paint (INP).
Good First Input Delay
The percentage of origins with "good" FID experiences, less than or equal to 100 ms. See FID in CrUX.
Poor First Input Delay
The percentage of origins with "poor" FID experiences, greater than 250 ms. See FID in CrUX.
Good Time to First Byte
The percentage of origins with "good" TTFB experiences, less than or equal to 800ms. See Time to First Byte (TTFB).
Poor Time to First Byte
The percentage of origins with "poor" TTFB experiences, greater than 1800ms. See Time to First Byte (TTFB).
Good First Paint
The percentage of origins with "good" FP experiences, less than or equal to 1 second.
Good DOM Content Loaded
