The silent failures

Your site can look perfect
and still fail silently.

Most teams ship every week without ever auditing what they shipped. The issues that hurt growth aren't the ones that show up in QA.

  • Slow pages quietly lose users
  • SEO issues reduce visibility
  • Accessibility gaps block real users
  • Security headers go missing on deploy
  • Broken links damage trust
  • Core Web Vitals affect rankings
  • Mobile issues hide in plain sight
  • Images bloat the bundle invisibly
