Slow load times and broken pages hurt the user experience and can frustrate visitors — even turn them away from your site. Site monitoring helps you catch these issues early. With relevant analytics and a data-driven approach to how your pages perform across different devices, locations, and traffic conditions, you can proactively address issues to provide the best website experience for your audience.

Read on to learn about the types of website performance monitoring tools available for various site objectives.

What’s website performance monitoring?

Website performance monitoring continuously tracks a website’s technical abilities. It focuses on how well your site functions — how fast it loads, whether pages are responsive across devices, how often it’s available (uptime), and how stable it is during high-traffic periods. It’s about ensuring your site performs consistently, regardless of where people come from or what device they use.

This is different from website analytics, which measures how visitors find and interact with your content. While website analytics tools measure performance metrics like page views, bounce rates, and conversion paths, website monitoring tools measure the user experience itself.

Types of web performance monitoring

Depending on your website’s complexity and needs, you can implement different types of performance monitoring, from simple checks to detailed diagnostics. Here are the most common approaches.

Synthetic performance monitoring

This type of monitoring mimics user interactions by running automated tests on your site from different browsers, devices, and locations. It helps benchmark your performance and catch glitches during updates.

For example, synthetic monitoring can test how quickly your homepage loads from Europe versus North America or how a subscription checkout performs across different mobile devices, using a simulation that doesn’t rely on actual traffic.

Basic website performance monitoring

Simple uptime checks and load time tracking are the hallmarks of basic performance monitoring. It tells you if your site is online and how long a page takes to load in a particular region. Basic monitoring only offers limited insight into why there might be slowdowns, but it’s a good starting point if you’re new to performance checks.

Mid-level website performance monitoring

Mid-level monitoring goes beyond simple uptime checks and helps you understand what might be slowing your site down. It measures how long it takes for the first part of your page to load (first contentful paint), when the largest element finishes loading (largest contentful paint), and whether the layout shifts around while loading (cumulative layout shift). These are part of Google’s Core Web Vitals, which directly impact search engine optimization (SEO) and the user experience.

For example, your blog might have steady traffic, but you see your engagement drop after a redesign. Mid-level monitoring tools can show you that large images or extra animations delay the page load.

Advanced website performance monitoring

Advanced monitoring tools track what real people actually experience when they visit your site. Known as real user monitoring (RUM), these tools collect performance data from visitors’ browsers so you can spot issues based on devices, locations, or connection types. This includes session replays (showing precisely what a user saw during their visit) and error tracking (identifying bugs or broken scripts).

For instance, if people in one country are being dropped from your site, RUM can reveal that pages load slowly only for users on a particular mobile network. You can then focus on fixing that issue rather than relying on guesswork.

How to track website performance monitoring: 5 best practices to build monitoring into your workflow

Ideally, you should build performance monitoring into your team’s regular workflow so your site always remains fast and reliable. Here are five best practices to help you stay ahead of technical issues.

1. Track uptime

Uptime monitoring checks whether your website is live and accessible to the public. It pings your site at regular intervals to confirm its online status. You want to know immediately when something breaks, not after a customer tells you.

If your site goes down, performance monitoring tools will notify your team through email or Slack the second your site becomes unreachable. Then, you can investigate and promptly resolve the issue so your site is up and running again.

2. Measure time to first byte

Time to first byte, or TTFB, measures how long it takes for a browser to receive the first portion of data from your server after a user makes a request, like submitting a form or adding an item to their cart. A high TTFB might indicate server-side issues like slow hosting, inefficient back-end code, or database delays, all of which slow down the entire loading process.

Tools like Google PageSpeed can measure your site’s TTFB. If it’s too high, consider optimizing your server setup or using a content delivery network (CDN) to deliver content faster.

3. Keep an eye on the bounce rate

Bounce rate is the percentage of people who leave your website after viewing only one page — without clicking, scrolling, or engaging.

While bounce rate is technically a user behavior metric (often found in analytics tools), sudden spikes can signal performance issues like broken links, long load times, or a poor mobile experience.

Use analytics tools to check bounce rate trends. If you notice unusually high bounce rates on specific pages, investigate their load speed, mobile responsiveness, or other underlying issues.

4. Monitor page speeds and load time

Page load times refer to how long it takes for a webpage to load completely and become interactive. Slow-loading pages frustrate people and lead to the bounce rates outlined above. They also affect search rankings by telling Google that users don’t find your site worthwhile.

Use page speed monitoring tools to test your site’s performance on different devices and network conditions. These tools will flag slow-loading elements like large images and tell you what to improve for faster page speeds.

5. Check database performance

Database performance is how quickly and efficiently your website handles requests, such as loading content or retrieving user data. If the database is slow to respond, it can delay page loads, cause timeouts, or even crash parts of the site.

A database is where your website stores and retrieves structured content like blog posts, product listings, user accounts, form submissions, and content management system (CMS) data. Whenever someone visits a dynamic page, the website often queries the database to load that content on the page. Queries are requests your site sends to the database to receive, update, or delete information.

If your website runs on a CMS or custom back end, use server logs or application monitoring tools to track query performance. Look for slow-running queries or bottlenecks and work with your team to optimize the query structure within your data for better performance.
