Getting Started

Get started with your first website performance monitor in just a few clicks.

What a Website Performance Monitor Checks

A website performance monitor runs a Lighthouse-based check against a URL of your choice, from a location you pick, on a schedule you control. Each run reports a Performance Score, SEO Score, Accessibility Score, Best Practices Score, and PWA Score, plus the Core Web Vitals (Largest Contentful Paint, First Input Delay, Cumulative Layout Shift) and other timing metrics like First Contentful Paint, Speed Index, Time to Interactive, and Total Blocking Time. Because the monitor keeps running on schedule, you get a history of these numbers instead of a single one-off snapshot, so you can tell whether a deploy, a new script, or a bloated image made things worse.

Creating your First Website Performance Monitor

Using the quick new website performance monitor configurator you can just add your website endpoint, select the location of your monitor, device and schedule interval and your ready to go:

What You Configure

• Test Name: a name is generated automatically from the current date and time, but you can rename it to something you'll recognize later, like "homepage EU" or "checkout page mobile".
• Test Location: the geographical location the check runs from. Pick one close to where most of your real visitors are, so the numbers reflect what they actually experience.
• URL: the website or web page you want monitored.
• Device: Mobile or Desktop. Each simulates loading the page on that device type, and scores can differ quite a bit between the two, so it's worth monitoring both if mobile traffic matters to you.
• Scheduling interval: how often the monitor runs, hourly, every 6 hours, every 12 hours, or every 24 hours.

Adding Alerts

Right after you create the monitor, an Alert Configurator popup appears so you can set up a notification without leaving the flow. You can skip it and add an alert later, either from the list of tests or from the Alerts page. See how to create a new alert and the full list of metrics you can trigger an alert on.

After the First Run

Once the monitor starts running on its schedule, results accumulate on the test's page, so you can watch scores and Core Web Vitals trend over days and weeks instead of judging your site off a single run. If you configured an alert, you get notified through the channels you set up whenever the metric you're watching crosses your threshold.

That's it: one configurator, a handful of fields, and you have a recurring check you can build alerts and trend tracking on top of.
