Technical Performance Index

What is Technical Performance Index?

Technical Performance Index measures site speed and Core Web Vitals critical for AI crawler efficiency. It combines page load speed (30%), Core Web Vitals (40%), server response time (20%), and resource optimization (10%) to determine whether AI systems can efficiently access and process your content.

Why This Metric Matters

  • Crawler Efficiency Fast sites allow AI to index more content per visit
  • User Experience Signal AI considers performance when determining quality
  • Citation Eligibility Slow sites are less likely to be cited

Performance Benchmarks

Google's Core Web Vitals thresholds

90-100
Excellent

Lightning fast. All Core Web Vitals pass. LCP <2.5s, FID <100ms, CLS <0.1. Perfect for AI crawlers.

70-89
Good

Good speed. Most Core Web Vitals pass. Minor optimizations needed. AI crawlers can access efficiently.

50-69
Average

Moderate speed. Some Core Web Vitals fail. Performance optimization required. Crawler budget impacted.

0-49
Poor

Slow site. Multiple Core Web Vitals failures. Urgent optimization needed. AI crawlers struggle to index.

How It's Calculated

Performance Index aggregates multiple speed and infrastructure metrics.

Weighted Formula

Core Web Vitals (LCP, FID, CLS) 40%
Page Load Speed 30%
Server Response Time (TTFB) 20%
Resource Optimization 10%

Why Core Web Vitals?

Google's Core Web Vitals are the industry standard for measuring real-world user experience. AI systems use these as trust signals.

Core Web Vitals Explained

LCP (Largest Contentful Paint)
Measures loading performance. Should occur within 2.5s of page load.
FID (First Input Delay)
Measures interactivity. Should be less than 100ms for good experience.
CLS (Cumulative Layout Shift)
Measures visual stability. Should maintain a score below 0.1.
TTFB (Time to First Byte)
Server responsiveness. Should be under 600ms for optimal performance.

How to Improve Your Score

Proven strategies to boost technical performance

  • Improve LCP Optimize largest image/element, use CDN, implement lazy loading
  • Reduce FID Minimize JavaScript execution, use web workers, defer non-critical scripts
  • Fix CLS Set size attributes for images, reserve space for ads, avoid inserting content above existing

  • Upgrade Hosting Move to faster server infrastructure or premium hosting
  • Enable Caching Implement server-side caching, browser caching, CDN caching
  • Optimize Database Index queries, optimize tables, use query caching

  • Compress Images Use WebP format, compress JPEG/PNG, implement responsive images
  • Minify Code Minify CSS, JavaScript, HTML files
  • Reduce Requests Combine files, remove unused code, implement HTTP/2

  • Implement CDN Use Cloudflare, AWS CloudFront, or similar CDN service
  • Geographic Distribution Serve content from servers closer to users
  • Edge Caching Cache static assets at edge locations globally
