1. Hotjar

Hotjar is a product suite that gives you insight into exactly how users are experiencing your site. Rather than just providing quantitative data, it also gives you qualitative information to complement your website monitoring, so you can zoom in on what elements your visitors engage with and the issues they run into.

Hotjar offers comprehensive product and website experience tools, such as:

  • Heatmaps: discover which elements of your site attract attention and which get ignored

  • Recordings: watch replays of user sessions to pinpoint what makes them rage click and u-turn

  • Funnels: identify where users drop off in your main conversion flows

  • Surveys and Feedback: collect long-form feedback to dive deeper into how your customers experience your site

  • Engage: easily schedule, host, record, and transcribe interviews to pinpoint usability issues on your site

Pro tip: not all feedback is useful. To find the insights that will help you take action and improve your site’s usability, filter user feedback by:

  • Rating: dislike or hate, to only review feedback from unhappy users

  • Responses with feedback, to only review feedback of users who took the time to explain why they were displeased

#Filter your feedback to get actionable ideas to improve your product

2. Pingdom

Pingdom dives deep into website performance metrics, providing users with actionable insights so your site always runs smoothly and your customers keep coming back.

Although Pingdom delivers technical information, their platform isn’t only for developers. The product’s reports present data clearly and concisely so team members working in departments like digital marketing and customer experience also understand it.

Pingdom’s tools help you keep an eye on website performance with:

  • Synthetic monitoring: simulate visitor interaction on your site to monitor the end-user experience with uptime monitoring, page speed, transaction monitoring, and alerting

  • Real user monitoring: enhance your site’s performance with data from actual site visitors using live maps, UX monitoring, page load performance, and user behavior metrics

3. UpTrends

UpTrends is a website monitoring service that makes website performance metrics clear and accessible, helping you explore and fix site issues quickly to minimize any impact on your bottom line.

It alerts you of website performance issues by reducing false positive alerts and offering a flexible system that notifies you via email, SMS, phone calls, and mobile apps. The tool integrates with Slack, Microsoft Teams, and PagerDuty, and also lets you build custom integrations with webhooks.

Use the following monitoring solutions:

  • Synthetics: conduct uptime monitoring with 233 checkpoints to track how your website performs in different locations and multi-browser monitoring of Core Web Vitals and W3C metrics in the latest Chrome and Edge browsers

  • Web app monitoring: dive deeper into your site’s core functions to ensure they’re easy for customers to interact with. This feature is prevalent for ecommerce sites because it focuses on interactive elements like shopping carts and payment screens. 

Pro tip: while monitoring your site’s performance, balance qualitative and quantitative data. Platforms like Pingdom and UpTrends provide many useful metrics and technical information, but you need more user-focused tools to fill in the blanks.

Hotjar Recordings and Heatmaps complement number-heavy reports and uncover how performance issues really affect the user experience.
