Single Page Analysis

What to Analyze

On-Page SEO

  • Title tag: 50-60 characters, includes primary keyword, unique
  • Meta description: 150-160 characters, compelling, includes keyword
  • H1: exactly one, matches page intent, includes keyword
  • H2-H6: logical hierarchy (no skipped levels), descriptive
  • URL: short, descriptive, hyphenated, no parameters
  • Internal links: sufficient, relevant anchor text, no orphan pages
  • External links: to authoritative sources, reasonable count

Content Quality

  • Word count vs page type minimums (see quality-gates.md)
  • Readability: Flesch Reading Ease score, grade level
  • Keyword density: natural (1-3%), semantic variations present
  • E-E-A-T signals: author bio, credentials, first-hand experience markers
  • Content freshness: publication date, last updated date

Technical Elements

  • Canonical tag: present, self-referencing or correct
  • Meta robots: index/follow unless intentionally blocked
  • Open Graph: og:title, og:description, og:image, og:url
  • Twitter Card: twitter:card, twitter:title, twitter:description
  • Hreflang: if multi-language, correct implementation

Schema Markup

  • Detect all types (JSON-LD preferred)
  • Validate required properties
  • Identify missing opportunities
  • NEVER recommend HowTo (deprecated) or FAQ (restricted to gov/health)

Images

  • Alt text: present, descriptive, includes keywords where natural
  • File size: flag >200KB (warning), >500KB (critical)
  • Format: recommend WebP/AVIF over JPEG/PNG
  • Dimensions: width/height set for CLS prevention
  • Lazy loading: loading="lazy" on below-fold images

Core Web Vitals (reference only — not measurable from HTML alone)

  • Flag potential LCP issues (huge hero images, render-blocking resources)
  • Flag potential INP issues (heavy JS, no async/defer)
  • Flag potential CLS issues (missing image dimensions, injected content)
