Overall Score: 0/100

Understanding Your Website Rating

A high-performing website is the foundation of digital success. This calculator uses a weighted algorithm to evaluate your site's quality based on industry standards set by Core Web Vitals and SEO best practices. We analyze four critical pillars: Performance, Mobile Responsiveness, Search Engine Optimization, and Accessibility.

The Four Pillars of Web Quality

  • Page Load Time: Speed is a direct ranking factor. Google research suggests that as page load time goes from 1s to 3s, the probability of bounce increases by 32%.
  • Mobile Optimization: With over 50% of global traffic coming from mobile devices, your site must be perfectly responsive and thumb-friendly.
  • SEO Health: This involves on-page elements like meta tags, header structures, and internal linking that help search engines understand your content.
  • Accessibility: Ensuring your site is usable for everyone, including those with visual or motor impairments, is not just a legal consideration but a UX necessity.
Pro Tip: Aim for a load time under 2 seconds and a mobile score above 90 to stay ahead of 75% of your competitors.

How We Calculate Your Rating

Our algorithm applies specific weights to each metric because not all factors impact user experience equally:

  • Speed Impact (30%): Calculated as a decay function where 0.5s is perfect and >5s results in significant penalties.
  • SEO & Mobile (25% each): High priority for organic growth and user retention.
  • Accessibility (20%): Critical for compliance and broad reach.

Real-World Example

If a website has a 3.0s load time (Score: 70), a Mobile score of 80, SEO score of 90, and Accessibility of 85, the calculation would look like this:

(70 * 0.3) + (80 * 0.25) + (90 * 0.25) + (85 * 0.20) = 80.5 (Grade: B)

How to Improve Your Score

If your grade is lower than an 'A', focus on these quick wins:

  1. Compress Images: Large images are the #1 cause of slow load times.
  2. Leverage Caching: Use browser caching to speed up return visits.
  3. Fix Broken Links: Improving SEO health starts with a clean link structure.
  4. Alt Text: Adding descriptive alt text to images boosts both SEO and Accessibility.
