Core Web Vitals

Core Web Vitals are the subset of Web Vitals that apply to all web pages and should be measured by all site owners. Each Core Web Vital represents a distinct facet of the user experience and reflects the real-world experience of a critical user-centric outcome.

Largest Contentful Paint (LCP)

LCP measures loading performance. It marks the point when the page's main content has likely loaded. This metric is important because it tells the user that the URL is actually loading and content is being rendered.

LCP Thresholds

  • Goodless than 2.5s
  • Needs Improvement2.5s - 4s
  • Poormore than 4s

Key Elements:

  • Images
  • Video elements
  • Large blocks of text
  • Background images

First Input Delay (FID)

FID measures interactivity. It quantifies the experience users feel when trying to interact with unresponsive pages. This metric helps identify instances where a page appears interactive but actually isn't.

FID Thresholds

  • Goodless than 100ms
  • Needs Improvement100ms - 300ms
  • Poormore than 300ms

Common Causes:

  • Heavy JavaScript execution
  • Long tasks (>50ms)
  • Large bundle sizes
  • Multiple third-party scripts

Cumulative Layout Shift (CLS)

CLS measures visual stability. It helps quantify how often users experience unexpected layout shifts. A low CLS helps ensure that the page is delightful to use by being visually stable.

CLS Thresholds

  • Goodless than 0.1
  • Needs Improvement0.1 - 0.25
  • Poormore than 0.25

Common Causes:

  • Images without dimensions
  • Dynamically injected content
  • Web fonts causing FOIT/FOUT
  • Actions waiting for network response

Additional Performance Metrics

Beyond Core Web Vitals, we track several additional metrics that provide deeper insights into your website's performance. These metrics help identify specific areas for improvement and optimization.

Time to First Byte (TTFB)

The time between the request for a resource and when the first byte of a response begins to arrive.

TTFB Thresholds

  • Optimal< 200ms
  • Acceptable200ms - 500ms
  • Poor> 500ms

First Contentful Paint (FCP)

The time when the browser renders the first bit of content from the DOM.

FCP Thresholds

  • Good< 1.8s
  • Needs Improvement1.8s - 3s
  • Poor> 3s

Time to Interactive (TTI)

The time it takes for the page to become fully interactive.

TTI Thresholds

  • Good< 3.8s
  • Needs Improvement3.8s - 7.3s
  • Poor> 7.3s

Total Blocking Time (TBT)

The total amount of time between FCP and TTI where the main thread was blocked.

TBT Thresholds

  • Good< 200ms
  • Needs Improvement200ms - 600ms
  • Poor> 600ms
