Market SEO — On-page, Technical, and AI Search Audit

Modern SEO has three surfaces: classic Google rankings, Core Web Vitals, and generative search (AI Overviews, ChatGPT browsing, Perplexity). This skill covers all three.

Workflow

1. Run python3 scripts/analyze_page.py <url> to get title, meta, headings, schema, canonical, viewport, tracking.
2. Fetch /robots.txt, /sitemap.xml, /llms.txt directly.
3. Read the page content for E-E-A-T signals (author bio, citations, specific detail).
4. Score each section, write the audit.

On-Page Checklist

Title tag

• Present, unique, 50–60 chars
• Primary keyword near the start
• Brand at the end ( | Brand or — Brand)
• Compelling enough to earn a click

Meta description

• 140–160 chars
• Includes the keyword naturally
• Has a reason to click (outcome, differentiator, number)

Headings

• Exactly one H1, contains the primary keyword, differs from the title
• H2s describe sections and contain secondary keywords
• No skipped levels (H2 → H4)

Images

• Every content image has descriptive alt text
• Decorative images have empty alt=""
• Below-fold images use loading="lazy"
• Filenames are descriptive (not IMG_0042.jpg)

Internal linking

• 3–10 contextual links per 1,000 words
• Descriptive anchor text (not "click here")
• No orphan pages (should be linked from at least one relevant page)

URL structure

• Human-readable, keyword-containing, under 75 chars, hyphens not underscores, lowercase

Technical SEO

Core Web Vitals targets (2024+)

CWV is a real ranking factor and a large conversion factor — flag failures as revenue issues, not just SEO issues.

E-E-A-T Assessment

Google ranks content by Experience, Expertise, Authoritativeness, Trustworthiness. Score each 0–10 with evidence.

• Experience — first-hand signals: screenshots, case data, "I built this and here's what happened"
• Expertise — author bio with credentials, accurate terminology, depth beyond surface
• Authoritativeness — inbound citations, press, recognized author names
• Trustworthiness — HTTPS, privacy policy, contact info, sourced claims, no dark patterns

AI Search / GEO Readiness (new surface)

Generative engines (Google AI Overviews, ChatGPT, Perplexity, Bing Copilot) pull passages, not pages. Optimize for citability:

• llms.txt — present and pointing to the canonical overview of the site
• Passage-level answers — clear Q-style H2/H3 immediately followed by a 40–80 word answer
• Factual density — specific numbers, dates, named entities (LLMs prefer these)
• Structured data — FAQPage, HowTo, Product, Article schema where applicable
• Crawler access — robots.txt does not block GPTBot, ClaudeBot, PerplexityBot, Google-Extended unless that's a deliberate policy
• Brand mention signals — consistent brand name, entity-style About page, Wikipedia/Wikidata presence
• Freshness signals — datePublished and dateModified in JSON-LD

Score this section 0–10 and include it as a first-class dimension.

Keyword Analysis

• Primary keyword — what is this page trying to rank for?
• Search intent — informational / commercial / transactional / navigational. Misalignment kills rankings.
• Placement audit — title, H1, first 100 words, one H2, URL, meta, alt text
• Secondary keywords — 5–10 related terms; confirm they appear naturally
• Density — 1–2% is fine, anything over 3% is stuffing

Quality Bar

• Always provide before/after for title and meta — clients act on concrete text, not abstract advice.
• Tie every fix to an expected outcome ("better CTR in SERP", "eligible for rich result", "passes CWV").
• Don't recommend schema types that aren't supported by the page content.
• If the site is already well optimized, say so and focus on the next tier (AI search, internal linking, topical authority).
