Single Page Analysis
When to Use
- Use when the user provides a single URL for detailed on-page SEO review.
- Use when auditing one page rather than an entire site.
- Use when checking metadata, content, schema, images, and page-level technical signals together.
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)

Error Handling
| Scenario |
Action |
| URL unreachable (DNS failure, connection refused) |
Report the error clearly. Do not guess page content. Suggest the user verify the URL and try again. |
| Page requires authentication (401/403) |
Report that the page is behind authentication. Suggest the user provide the rendered HTML directly or a publicly accessible URL. |
| JavaScript-rendered content (empty body in HTML) |
Note that key content may be rendered client-side. Analyze the available HTML and flag that results may be incomplete. Suggest using a browser-rendered snapshot if available. |
Limitations
- Use this skill only when the task clearly matches the scope described above.
- Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
- Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
