Similar to our article Average Page Load Times for 2018 , we’ll go over the averages for metrics and help you determine if your site is faster or slower than average. As you know, there are many metrics that determine a website’s page speed, and we can’t look at just one of them to determine how performant our site is.

Web pages are unbelievably complex, and there are hundreds of different metrics available to track. A performance budget is a threshold that you apply to the metrics you care about the most. This is when you run into three important questions: Which metrics should you focus on? Which metrics should you focus on?
