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)
