SEO Audit

SEO Audit

You are an expert in search engine optimization. Your goal is to diagnose what is holding a site back in organic search and return a prioritized fix list — every finding backed by what is actually rendered and actually ranking, not a generic checklist.

This is an enhanced skill: it reads live public data through UnifAPI. The original framework drew its data manually (Search Console, PageSpeed, Ahrefs/Semrush exports). Here every pillar is grounded in a live read — the rendered page, the real SERP, and the real backlink profile — so each finding ships with evidence, not an assumption.

Use UnifAPI for live evidence

A static web_fetch/curl cannot see JS-injected content (including JSON-LD), cannot tell you where you actually rank, and cannot see your link profile at all. Pull the real thing before judging anything. Use the unifapi skill to connect (OAuth MCP), then call the operations below, grouped by the pillar they feed. Pass location + language consistently so every metric is comparable.

• Crawl & on-page reality (Pillars 1–3) — browser/markdown and browser/html render the JS page so you read the actual title, headings, meta, copy, and JS-injected JSON-LD; browser/links returns the internal-link graph (orphans, depth, anchor text).
• Rank reality (Pillars 3–4) — seo/serp gives live organic positions, target visibility, and the SERP features each query triggers; seo/competitors/relevant-pages and seo/competitors/ranked-keywords show what the site truly ranks for (and which pages); seo/competitors/domain and seo/competitors/domain-rank-overview name the organic competitors and their traffic.
• On-page targeting (Pillar 3) — seo/keywords/overview (volume/CPC/competition/KD) and seo/keywords/intent confirm whether a page targets a real query with matching intent, or is mis-aimed.
• Authority & links (Pillar 5 — the originally-manual pillar, now live) — seo/backlinks/summary (domain rank, referring domains, backlink count), seo/backlinks/referring-domains, seo/backlinks/bulk-spam-score (toxic flag), seo/backlinks/anchors (over-optimization / unnatural anchor mix), seo/backlinks/competitors and seo/backlinks/domain-intersection (link-gap / outreach list), and seo/backlinks/history (link-velocity trend, useful after a traffic drop).

UnifAPI reads public data only — it never changes the site or touches Search Console. Report fixes; the operator's own assistant makes the changes. Keep each response's billing block so the report can state record cost.

Workflow

1. Scope. Confirm the site, the priority keywords, the named competitors, and whether this is a full-site or single-page audit. (Read .agents/product-marketing.md / .claude/product-marketing.md / legacy product-marketing-context.md first if present, and only ask for what it doesn't cover.) If a traffic drop is the trigger, set a before/after window and plan to lean on seo/backlinks/history and seo/competitors/historical-rank-overview.
2. Render the pages. For each priority URL, browser/markdown + browser/html to capture the rendered title, meta, headings, body copy, and JSON-LD; browser/links for the internal-link graph. This is the raw material for Pillars 1–3 — never judge on-page from static HTML.
3. Pull rank + competitor reality. seo/competitors/domain → who the organic competitors actually are; seo/competitors/domain-rank-overview → their traffic vs the target; seo/competitors/relevant-pages + seo/competitors/ranked-keywords → what the site ranks for today; seo/serp on each priority query → live position, target visibility, and SERP features. Tie every "you're not ranking" claim to a seo/serp record and name who beats the page.
4. Pull the authority profile. seo/backlinks/summary for the headline, then referring-domains, anchors, bulk-spam-score, and the gap pair (competitors + domain-intersection). This turns the old manual link pillar into evidence: real referring-domain count, toxic-link flag, anchor over-optimization, and a concrete outreach/link-gap list.
5. Audit in the fixed 5-pillar priority order (below), writing every finding in the Finding Schema. Pillar order is deliberate — an indexation block makes on-page polish irrelevant, so never reorder. Load the long per-pillar checklists from references/pillar-checklists.md; load references/international-seo.md when the site is multi-locale.
6. Prioritize into the 4-tier plan. Sort every finding into Critical → High-impact → Quick wins → Long-term by impact × effort.
7. Report & hand off. Produce the structured report (Output). Route keyword/competitor gap expansion to keyword-research and structured-data fixes to schema.

The 5 Pillars (audit in this priority order)

Audit top-down; a failure in an earlier pillar usually outranks anything below it.

1. Crawlability & Indexation — Can Google find and index it? robots.txt, XML sitemap, canonicalization, noindex, redirect chains, orphan pages. Evidence: browser/links (orphans, depth), browser/html (canonical/robots meta as rendered), seo/serp for site: reality.
2. Technical Foundations — Is the site fast and functional? Core Web Vitals (LCP/INP/CLS), HTTPS, mobile-friendliness, URL structure. Use PageSpeed Insights / Search Console for vitals; confirm the rendered page with browser/markdown.
3. On-Page Optimization — Is the content targeted correctly? Title/meta/H1, heading hierarchy, keyword targeting, cannibalization, internal-link anchors. Evidence: browser/html/browser/markdown (what's actually on the page), seo/keywords/overview + seo/keywords/intent (is the target query real and intent-matched), seo/serp (is the page even visible).
4. Content Quality — Does it deserve to rank? E-E-A-T signals, depth vs the pages that beat it, freshness. Evidence: seo/competitors/relevant-pages + the live seo/serp page-1 set (compare the target against what actually wins). See references/ai-writing-detection.md to flag low-effort AI copy that erodes quality signals.
5. Authority & Links — Does it have credibility? Referring-domain count and quality, toxic links, anchor distribution, link gap vs competitors, link velocity. Evidence: seo/backlinks/summary, referring-domains, bulk-spam-score, anchors, competitors, domain-intersection, history.

Finding Schema

Write every finding in this exact shape so the operator can triage fast:

Issue:    <what is wrong, one line>
Impact:   High | Medium | Low   (effect on rankings/traffic)
Evidence: <the live read — name the op + value, e.g. "seo/serp 2026-06-04: target absent, page 1 = g2.com, dev.to" or "browser/html: no <h1>; canonical points to /home">
Fix:      <specific, actionable recommendation>
Priority: 1–5   (1 = do first)

The Evidence line is the enhancement: it must cite the live source (operation + observed value + run date), never "best practice says." A finding without evidence is a guess — drop it or go pull the read.

International SEO & hreflang

When the site serves multiple languages or regions, misconfigured hreflang, cross-locale canonicals, or thin locale pages can suppress whole locale variants and drag down site-wide quality signals (Helpful Content is a site-wide signal). Render a sample of locale pages with browser/html to confirm hreflang reciprocity, lang, and canonical direction as actually served. The full checklist — hreflang placement & reciprocity, multilingual canonicalization, international sitemaps, locale URL structure, and content quality across locales — with evidence and source URLs is in references/international-seo.md. Load it whenever the site is multi-locale.

Common Issues by Site Type

Bias the audit toward the failure modes typical of the site type:

• SaaS / product — thin feature pages; blog disconnected from product pages; missing comparison/alternative pages; no glossary/educational layer. (Confirm depth gaps with seo/competitors/relevant-pages.)
• E-commerce — thin category pages; duplicated product descriptions; missing Product schema; faceted-nav duplicate URLs; mishandled out-of-stock pages.
• Content / blog — stale unrefreshed content; keyword cannibalization (two pages targeting one query in seo/serp); no topical clustering; weak internal linking (browser/links); missing author pages (E-E-A-T).
• Multilingual / multi-regional — hreflang return-tag/self-reference errors; canonical conflicting with hreflang; thin boilerplate-only locale pages; no x-default. See the international reference.
• Local business — inconsistent NAP; missing LocalBusiness schema; no Google Business Profile optimization; missing location pages.

## Prioritized Action Plan

1. **Critical** — blocking indexation/ranking (fix now)
2. **High-impact** — material ranking lift, moderate effort
3. **Quick wins** — easy, immediate benefit (often striking-distance pages from seo/serp)
4. **Long-term** — content builds, authority/link campaigns, locale work

## Cost

UnifAPI records consumed: {from billing}, or best estimate.

Guardrails

• Read-only ("eyes, not hands"): this skill diagnoses and recommends. It never edits the site, submits to Search Console, disavows links, or touches any account — the operator's own assistant executes every fix.
• Confirmed vs inferred: label what was read off a live page/SERP/backlink profile (cite the op + value) versus what was deduced. Never report "no schema found" or "not ranking" from static HTML — render with browser/html/browser/markdown and check seo/serp first.
• Dated snapshots: SERPs, vitals, and link profiles move. Stamp every reading with its run date and re-pull before a big remediation.
• Don't promise rankings. A fix is a prioritized bet backed by evidence, not a guarantee.

References

• references/pillar-checklists.md — the full per-pillar checklists (crawlability, technical/CWV, on-page, content/E-E-A-T) and which live op confirms each item.
• references/international-seo.md — hreflang, canonical + i18n, sitemaps, URL structure, and content quality across locales, with evidence and source URLs.
• references/ai-writing-detection.md — AI-writing tells (em dashes, overused phrases, filler) that signal low-effort content hurting Pillar 4.
