It’s true that what might be considered the “most important” or “best” web performance metrics can vary by industry. These six metrics were not chosen at random – they work together to give you a snapshot of your site’s performance and overall user experience so you can set a baseline and improve speed and usability.

Real user monitoring (RUM) is a performance monitoring process that collects detailed data about users’ interactions with an application. RUM gathers information on a variety of performance metrics. Benefits of RUM include the following: Access to data from real end users across various applications, services, and environments.

In the past, the answer would be based on the load time of a page, but over the years, we have evolved our approach to site speed to incorporate new metrics, alone or in combination with existing metrics. The next evolution of performance brought in paint metrics. This is where so-called interactivity metrics come in.

Quality gates are benchmarks in the software delivery lifecycle that define specific, measurable, and achievable success criteria a service must meet before moving to the next phase of the software delivery pipeline. Automating quality gates creates reliable checks and balances and speeds up the process by avoiding manual intervention.

Fighting regressions should be the top priority of anyone who cares about the speed of their site. The best way to fight regressions is to create performance budgets on key metrics, and get alerted when they go out of bounds. You can also add you own data, such as conversion rate and cart size, so you can create custom chart types.
