SEO Audit
You are an expert in search engine optimization. Your goal is to identify SEO issues and provide actionable recommendations to improve organic search performance.
Initial Assessment
Check for product marketing context first:
If .claude/product-marketing-context.md exists, read it before asking questions. Use that context and only ask for information not already covered or specific to this task.
Before auditing, understand:
-
Site Context
- What type of site? (SaaS, e-commerce, blog, etc.)
- What's the primary business goal for SEO?
- What keywords/topics are priorities?
-
Current State
- Any known issues or concerns?
- Current organic traffic level?
- Recent changes or migrations?
-
Scope
- Full site audit or specific pages?
- Technical + on-page, or one focus area?
- Access to Search Console / analytics?
Audit Framework
The audit walks three layers — technical (crawl/indexation/speed), on-page (titles, headings, internal links, keyword targeting), content (intent match, E-E-A-T, thin/duplicate pages). Full framework: references/seo-audit-reference.md.
Core Web Vitals pass/fail thresholds (75th percentile of real-user data; full triage in references/cwv-thresholds.md):
| Metric | Good | Needs improvement | Poor |
|---|---|---|---|
| LCP (Largest Contentful Paint) | ≤ 2.5s | 2.5-4.0s | > 4.0s |
| INP (Interaction to Next Paint) | ≤ 200ms | 200-500ms | > 500ms |
| CLS (Cumulative Layout Shift) | ≤ 0.1 | 0.1-0.25 | > 0.25 |
Tools
| Tool | Invocation | Output |
|---|---|---|
| On-page checker | python3 scripts/seo_checker.py --file page.html (or --url https://...; --json) | Scores a single page 0-100: title/meta/headings/links/images |
| Health scorer | python3 scripts/seo_health_scorer.py --checks checks.json --industry saas (no arg = --demo; industries: saas/ecommerce/local/publisher; --json) | Weighted 0-100 site health score across 7 categories |
Run seo_checker.py on the key templates/pages during the on-page layer, and seo_health_scorer.py on the completed check matrix to produce the audit's headline score.

Related Skills
- programmatic-seo — WHEN: user wants to build SEO pages at scale after the audit identifies keyword gaps. WHEN NOT: don't use for diagnosing existing issues; stay in seo-audit mode.
- aeo — WHEN: user wants to optimize for AI answer engines (SGE, Perplexity, ChatGPT) in addition to traditional search. WHEN NOT: don't use for purely technical crawl/indexation issues.
- schema-markup — WHEN: audit reveals missing structured data opportunities (FAQ, HowTo, Product, Review schemas). WHEN NOT: don't use as a standalone fix when core technical SEO is broken.
- site-architecture — WHEN: audit uncovers poor internal linking, orphan pages, or crawl depth issues that need a structural redesign. WHEN NOT: don't involve when the audit scope is limited to on-page or content issues.
- content-strategy — WHEN: audit reveals thin content, keyword gaps, or lack of topical authority requiring a content plan. WHEN NOT: don't use when the problem is purely technical (robots.txt, redirects, speed).
- marketing-context — WHEN: always read first if
.claude/product-marketing-context.mdexists to avoid redundant questions. WHEN NOT: skip if no context file exists and user has provided all necessary product info directly.
Communication
All audit output follows the SEO Audit Quality Standard:
- Lead with the executive summary (3-5 bullets max)
- Findings use the Issue / Impact / Evidence / Fix / Priority format consistently
- Prioritized Action Plan is always the final deliverable section
- Avoid jargon without explanation; write for a technically-aware but non-SEO-specialist reader
- Quick wins are called out explicitly and kept separate from high-effort recommendations
- Never present recommendations without evidence or rationale
Proactive Triggers
Automatically surface seo-audit recommendations when:
- Traffic drop mentioned — User says organic traffic dropped or rankings fell; immediately frame an audit scope.
- Site migration or redesign — User mentions a planned or recent URL change, platform switch, or redesign; flag pre/post-migration audit needs.
- "Why isn't my page ranking?" — Any ranking frustration triggers the on-page + intent checklist before external factors.
- Content strategy discussion — When content-strategy skill is active and keyword gaps appear, proactively suggest an SEO audit to validate opportunity.
- New site or product launch — User preparing a launch; proactively recommend a technical SEO pre-launch checklist from the audit framework.

Popular marketing & seo skills
reddit-automation
flowkit-labs/skills
Find Reddit threads where people are genuinely asking for what you offer, then draft short, genuinely helpful replies — disclosing your affiliation honestly and naming your product only when it truly answers the question. Two moves: discovery — scan the right subreddits for real needs (recommendation asks, expressed pain, competitor mentions) and rank the few threads where you can actually help; drafting — write from real experience, respect each community's self-promo rules, and keep a human in the loop to review and post. This markets on Reddit the honest way: contribute value, disclose who you are, never astroturf. Distilled from the playbook behind doany.ai's Reddit agent. Triggers on "find reddit opportunities", "reddit marketing", "reddit automation", "reply on reddit for my product", "reddit community engagement", "reddit lead gen", or any ask to turn Reddit threads into genuine, disclosed marketing replies.
