Overall Performance Score

A score from 0-100 calculated by Google Lighthouse, summarizing the page's overall performance across multiple metrics.

Largest Contentful Paint (LCP)

Measures the time it takes for the largest image or text block to become visible. A good LCP helps users feel that the page is loading quickly. (Core Web Vital)

Interaction to Next Paint (INP)

Measures the page's overall responsiveness to user interactions (like clicks or taps). A low INP ensures the page feels fast and fluid. (Core Web Vital)

Cumulative Layout Shift (CLS)

Measures visual stability, scoring how much unexpected layout shifts occur during loading. A low CLS prevents users from accidentally clicking the wrong thing. (Core Web Vital)

First Contentful Paint (FCP)

Marks the time when the first piece of content from the DOM (e.g., text, an image) is rendered on the screen. It's the first feedback to the user that the page is actually loading.

Time to First Byte (TTFB)

Measures how long it takes for a browser to receive the very first byte of data from the server. This indicates server responsiveness and network conditions.
