12 website monitoring tools to improve site performance and UX

Website monitoring is the ongoing process of ensuring your site is working as expected—and helping you know when it’s not. Consistent monitoring is key to maintaining a successful, high-performing website. It helps your team zero in on website issues, find speedy resolutions, minimize the negative impact on your user experience (UX), and keep your brand's stellar reputation intact.

But without the right tools, monitoring your website can be a labor-intensive, time-consuming process that requires a great eye for detail.

Use a combination of the tools in this article to make the website monitoring process more efficient, helping you improve your site's usability, performance, health, and security for a delightful user experience.

1. Contentsquare

It combines the quantitative data you need to track your KPIs with the qualitative insights necessary to really understand them. As a usability monitoring tool, it’s second to none. 

You can study the hard numbers on your site’s performance with tools like

• Benchmarks: allows you to compare your basic web analytics to competitors’ sites. See where you stand in relation to others on things like bounce rate, conversion rate, session time and new vs. returning visitors

• Speed Analysis: monitors your site’s load speed and performance in different geographic locations, and offers customized suggestions to help you improve it

• Heatmaps: a tool that visualizes your user behavior data, revealing which areas of a page hold user attention, and which get ignored 

• Session Replays: watch recordings of user sessions to understand your site’s usability from their perspective, and see which elements make people rage click or u-turn 

• Surveys: helps you collect feedback, so users can tell you directly how they find the experience of your site
