Web Vitals

Product: WPMazic SEO Pro

The Web Vitals module in WPMazic SEO provides a performance snapshot of your website based on Core Web Vitals-style measurements. It helps you understand how fast, stable, and responsive your site feels to real users, and highlights areas that may negatively impact search rankings or user experience.

What it is

Web Vitals is a performance analysis dashboard powered by PageSpeed Insights data. It evaluates your website using key metrics such as loading speed, interactivity, and visual stability to determine whether your site delivers a good user experience.

What it is used for

  • Check overall site performance using Core Web Vitals metrics
  • Identify slow-loading pages and performance bottlenecks
  • Understand how performance impacts SEO and user experience
  • Detect issues affecting conversions and engagement
  • Monitor improvements after optimization changes

Key Metrics

  • Largest Contentful Paint (LCP): Measures loading performance (how fast main content loads)
  • Interaction to Next Paint (INP): Measures responsiveness (how quickly the site reacts to user input)
  • Cumulative Layout Shift (CLS): Measures visual stability (unexpected layout shifts)

Key Features

  • Performance Score: Overall page speed and performance rating
  • Mobile & Desktop Analysis: Separate performance insights for different devices
  • Detailed Metrics Breakdown: Understand each Core Web Vital individually
  • Improvement Suggestions: Actionable recommendations from PageSpeed Insights
  • Historical Tracking (if enabled): Monitor performance improvements over time

Understanding the metrics

Largest Contentful Paint (LCP)

Measures how quickly the main content of a page loads. A good LCP should be under 2.5 seconds.

Interaction to Next Paint (INP)

Measures how responsive your site is when users interact with it. A good INP should be under 200 milliseconds.

Cumulative Layout Shift (CLS)

Measures visual stability. A good CLS score should be below 0.1.

Best Practices

  • Optimize images using modern formats (WebP/AVIF)
  • Use caching and CDN to improve loading speed
  • Minimize CSS and JavaScript files
  • Avoid layout shifts by defining image and ad sizes
  • Reduce server response time with optimized hosting
  • Lazy load non-critical resources

Troubleshooting

Analysis not working

  • Ensure your PageSpeed API key is valid
  • Check API usage limits
  • Verify internet connectivity from your server

Low performance score

  • Check large images or unoptimized media
  • Reduce unused CSS/JS
  • Enable caching and compression
  • Review third-party scripts affecting performance

Differences between mobile and desktop scores

  • Mobile devices have lower processing power
  • Network conditions are simulated differently
  • Focus on improving mobile performance first

Compatibility & Notes

  • Requires a valid PageSpeed Insights API key
  • Data is fetched from Google PageSpeed Insights
  • Results may vary depending on network and server conditions
  • Mobile and desktop scores are calculated separately

  • Website owners improving user experience
