What performance monitoring covers
Focus performance monitoring on pages and flows where slowdowns have real business impact.
Rendered-page context
Review timing signals alongside whether the page actually rendered useful visible content.
API and dependency visibility
See first-party API calls and failed resources that can slow or break dynamic pages.
Journey-level impact
Use user journeys to understand whether slow pages affect checkout, signup, login, forms, or onboarding.
Performance problems are customer-experience problems
A slow page may not be fully down, but it can still cost conversions, trust, and support time. Visitors can abandon checkout, miss a form, or lose confidence when pages load slowly or important content appears late.
NorthDuty records performance and timing context inside website health checks, then connects that context to uptime, page rendering, JavaScript errors, first-party API calls, visual changes, and user journeys.
Why website performance monitoring matters
Performance should be monitored where it changes user behavior, not only as a technical metric.
- Catch slow pages before they quietly reduce conversion
- Connect performance signals to page health and user journeys
- Prioritize checkout, signup, login, forms, pricing, and campaign pages
- See failed resources and API calls that contribute to poor page experience
- Review performance after deployments, campaigns, experiments, and integration changes

Answers to common questions about this monitoring feature and when teams should use it.
What is website performance monitoring?
Website performance monitoring tracks timing and page experience signals so teams can see when important pages become slow enough to hurt visitors.
Which pages should I monitor for performance first?
Start with homepage, campaign landing pages, pricing, checkout, signup, login, forms, product pages, and other routes tied to revenue or customer access.
How is performance monitoring different from uptime monitoring?
Uptime monitoring checks whether a page responds. Performance monitoring adds timing context so teams can catch pages that are reachable but slow or degraded.
