   1. 1. • The LCP measures webpage load performance, specifically how quickly the largest image or text block renders. A good LCP score is within the first 2.5 seconds.
         • The LCP is crucial for user experience and SEO, as it impacts perceived load speed and reassures users of the page’s usefulness. This is particularly important in a vibrant, fast-paced state like San Francisco, where users expect quick and efficient web experiences.

2. Interaction to Next Paint (INP): measures the responsiveness of a web page by tracking the time between user interactions (like clicks or key presses) and the next visual update, helping assess user experience during interactions. By improving the INP ensures that websites are highly responsive, enhancing user engagement, especially vital for London’s tech-savvy population.

The INP is 123ms, and falls within the recommended value of 200ms.

 

 

3. Total Blocking Time (TBT): 1.380ms (failing to match the recommended value)

TBT measures the amount of time during which the main thread is blocked and unable to respond to user input. It captures the time between the First Contentful Paint (FCP) and Time to Interactive (TTI) where tasks exceed 50ms.

• A high TBT indicates that the main thread is often busy, delaying responsiveness and negatively affecting the user experience.

What that means for User Experience:

• • Interaction Delays: Users experience delays when clicking buttons, filling out forms, or performing other interactive actions.
  • Increased Bounce Rates: Slow and unresponsive websites lead to frustration, causing users to leave the site quickly, increasing bounce rates.
  • Reduced User Engagement: Users are less likely to engage with a website that feels slow, leading to lower conversion rates and reduced time spent on site.

What that means for SEO:

• • Lower Rankings: Google’s algorithm considers user experience metrics, including TBT. High TBT can negatively impact search engine rankings, reducing organic traffic.
  • Page Experience Signals: As part of the Core Web Vitals, TBT affects page experience signals. Poor performance can lead to decreased visibility in search results.

HOw to Improve TBT:

• • Optimize JavaScript: Minimize and defer non-critical JavaScript to reduce blocking time.
  • Reduce Long Tasks: Break up long tasks into smaller, asynchronous tasks to prevent blocking the main thread.
  • Efficient Resource Loading: Use techniques like code splitting, lazy loading, and optimizing third-party scripts to ensure resources are loaded efficiently.
  • Use Web Workers: Offload heavy computations to web workers to keep the main thread free.

4. Cumulative Layout Shift (CLS) is a metric that quantifies how much visual material moves around on a website as it loads. CLS evaluates visual stability by tracking unexpected layout shifts. Ensuring a low CLS provides a smooth browsing experience, which is critical for maintaining user trust and satisfaction. Recommended value less than 0.1.

Good CLS score 0.048.
