P4 SiteCheck

A no-signup website report card that translates technical signals into decisions a business owner can understand.

The problem

Raw audit scores do not explain what to do next.

Performance, accessibility, search, SSL, and broken-link tools often expose data without making the business impact or priority clear.

The system response

  • Real PageSpeed-derived performance data
  • Accessibility and SEO signals
  • SSL and broken-link checks
  • Plain-English letter grades and interpretation
  • No-signup acquisition path
  • Foundation for repeat monitoring services

Verified internal record

The engine returns keyed, usable data.

The July 4, 2026 internal engine verdict records successful keyed API responses across mobile and desktop performance, accessibility, SEO, SSL, and letter-grade fields. Broader industry-page expansion remains gated behind content quality and sample verification.
