Performance Metrics We Track
Largest Contentful Paint (LCP)
Measures how fast the largest content element loads. Google recommends under 2.5 seconds. We alert you when LCP exceeds your threshold.
Interaction to Next Paint (INP)
Measures responsiveness to user interactions. A good INP is under 200ms. Track how quickly your pages respond to clicks and keypresses.
Cumulative Layout Shift (CLS)
Measures visual stability. Unexpected layout shifts frustrate users. A good CLS is under 0.1 — we alert when yours exceeds it.
Time to First Byte (TTFB)
Measures server response time. Our TTFB metric matches UptimeRobot's methodology — pure first-byte timing without body download time.
PageSpeed Score
Google PageSpeed Insights score combining all performance metrics. Track the overall health of your website performance over time.
Historical Trends
View performance metrics over time with interactive charts. Spot gradual degradations before they become critical issues.
Frequently Asked Questions
What are Core Web Vitals?
Core Web Vitals are three metrics Google uses to measure user experience: Largest Contentful Paint (LCP) for loading speed, Interaction to Next Paint (INP) for interactivity, and Cumulative Layout Shift (CLS) for visual stability. Passing these metrics is a ranking factor in Google Search.
How does performance monitoring affect SEO?
Google uses Core Web Vitals as a ranking signal. Sites with good CWV scores rank higher. UptimePoint helps you catch performance regressions before they impact your rankings by alerting you when LCP, INP, or CLS exceed recommended thresholds.
What is a good response time?
A good Time to First Byte (TTFB) is under 200ms. For LCP, Google recommends under 2.5 seconds. UptimePoint tracks TTFB pur (matching UptimeRobot's methodology) and alerts you when response times degrade beyond your configured threshold.
How often are performance checks run?
Performance checks run at your configured interval (from 30 seconds on Enterprise+ to 5 minutes on Free plan). PageSpeed metrics like Core Web Vitals are gathered using the Google PageSpeed Insights API.
