This is an update to my 2020 article Site-Speed Topography. Around two and a half years ago, I debuted my Site-Speed Topography technique for getting broad view of an entire site’s performance from just a handful of key URLs and some readily available metrics. What Is Site-Speed Topography? Are any metrics over budget?

Poor user experience or application performance negates any advantages you achieve in delivery speed or production cost. Understanding software quality metrics, especially in automated testing, helps us identify what is working well and what needs improvement. Put simply, if it does not work, it is not worth producing.

VMAF is a video quality metric that Netflix jointly developed with a number of university collaborators and open-sourced on Github. One aspect that differentiates VMAF from other traditional metrics such as PSNR or SSIM, is that VMAF is able to predict more consistently across spatial resolutions, across shots, and across genres (for example.

Google do strongly encourage you to focus on site speed for better performance in Search, but, if you don’t pass all relevant Core Web Vitals (and the applicable factors from the Page Experience report) they will not push you down the rankings.
