  SEO SCORING SYSTEM
  ━━━━━━━━━━━━━━━━━━━━━━━━━━

  Your page receives a weighted score across 5 categories:
  • Meta (30%) — Title, description, keywords
  • Technical (25%) — Canonical, robots, viewport
  • Content (20%) — Headings structure, text quality
  • Social (15%) — OG tags, Twitter cards
  • Schema (10%) — Structured data presence

  Grades: A (90+), B (80+), C (70+), D (60+), F (<60)

  ━━━━━━━━━━━━━━━━━━━━━━━━━━
  PRIVACY FIRST
  ━━━━━━━━━━━━━━━━━━━━━━━━━━

  Static SEO analysis runs 100% locally in your browser.
   The optional AI Analysis feature sends only page metadata (URL, title, heading counts) to Groq's API when you click "Analyze with AI" — never automatically. Your API key is stored locally and
  never shared with teraSEO.
