| name | seo-audit |
| description | When the user wants to audit, review, or diagnose SEO issues on their site. Also use when the user mentions "SEO audit," "technical SEO," "why am I not ranking," "SEO issues," "on-page SEO," "meta tags review," "SEO health check," "my traffic dropped," "lost rankings," "not showing up in Google," "site isn't ranking," "Google update hit me," "page speed," "core web vitals," "crawl errors," or "indexing issues." Also covers generative-engine visibility (GEO/AEO): "AI Overviews," "AI search," "not showing up in ChatGPT," "get cited by AI," "GEO," "answer engine optimization," "llms.txt," "AI crawlers," "GPTBot," or "ClaudeBot." Use this even if the user just says something vague like "my SEO is bad" or "help with SEO" — start with an audit. In AKILI-SPECS projects, /akili-seo loads this skill in its audit phase. |
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 .agents/product-marketing.md exists (or .claude/product-marketing.md, or the legacy product-marketing-context.md filename, in older setups), 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
Schema Markup Detection Limitation
web_fetch and curl cannot reliably detect structured data / schema markup.
Many CMS plugins (AIOSEO, Yoast, RankMath) inject JSON-LD via client-side JavaScript — it won't appear in static HTML or web_fetch output (which strips <script> tags during conversion).
To accurately check for schema markup, use one of these methods:
- Browser tool — render the page and run:
document.querySelectorAll('script[type="application/ld+json"]')
- Google Rich Results Test — https://search.google.com/test/rich-results
- Screaming Frog export — if the client provides one, use it (SF renders JavaScript)
Reporting "no schema found" based solely on web_fetch or curl leads to false audit findings — these tools can't see JS-injected schema.
Priority Order
- Crawlability & Indexation (can Google find and index it?)
- Technical Foundations (is the site fast and functional?)
- On-Page Optimization (is content optimized?)
- Content Quality (does it deserve to rank?)
- Authority & Links (does it have credibility?)
GEO is a layer, not a sixth priority. Generative-engine visibility (AI Overviews, ChatGPT,
Perplexity) is applied on top of pages that already rank or can — roughly three quarters of AI
Overview citations come from pages already in the top 10. Never trade a fix from the list above for a
GEO fix. Run the priority order first, then apply the GEO section.
Technical SEO Audit
Crawlability
Robots.txt
- Check for unintentional blocks
- Verify important pages allowed
- Check sitemap reference
Disallow is not noindex. A disallowed URL can still be indexed (from external links) and will show as "Indexed, though blocked by robots.txt". To remove a page from the index you must let Google crawl it and serve noindex — blocking it prevents Google from ever seeing the directive. A noindex line inside robots.txt is unsupported and ignored.
AI crawler directives (see GEO reference for the full agent table)
- Distinguish training agents (
GPTBot, ClaudeBot, Google-Extended) from retrieval agents (OAI-SearchBot, Claude-SearchBot, PerplexityBot) and user-triggered fetchers (ChatGPT-User, Claude-User, Perplexity-User)
- High-impact finding: a blanket AI-bot block removes the site from AI answers as well as from training corpora. Confirm the client's intent before treating either state as correct
Google-Extended is a robots.txt token only — it never appears in logs, and blocking it does not affect Googlebot, Search, or AI Overviews- Where the requirement is genuine prevention rather than preference, note that robots.txt is advisory and escalate to WAF/bot management

International SEO & Localization
Check when the site serves multiple languages or regions. Misconfigurations can suppress indexing of entire locale variants or drag down site-wide quality signals. See International SEO reference for evidence and source URLs.
Hreflang
Three equivalent placement methods: HTML <link> in <head>, HTTP Link headers, XML sitemap <xhtml:link>. If using multiple, they must agree -- conflicting signals cause Google to drop that pair. For 10+ locales, prefer sitemap-based (no page weight, no per-request cost).
Check for:
- Self-referencing entry on every page (page must include itself in the hreflang set)
- Reciprocal links (if A points to B, B must point back to A -- or both are ignored)
- Valid codes: ISO 639-1 language + optional ISO 3166-1 Alpha 2 region (e.g.,
en, en-GB -- never en-UK)
x-default present, pointing to fallback page (language selector or default locale)- All target URLs return 200, are indexable, and match their canonical URL
- No duplicate language-region codes pointing to different URLs
Common errors: Missing self-referencing entry (all hreflang ignored). No return tag / one-directional (pair dropped). Invalid codes like en-UK (use en-GB). Hreflang target is non-canonical, 404, or blocked (cluster discarded). HTML and sitemap annotations disagree (conflicting pair dropped).
At scale: <xhtml:link> children don't count toward 50K URL sitemap limit, but the 50MB file size limit becomes the bottleneck (plan 2K-5K URLs per file with full hreflang). Focus hreflang on pages receiving wrong-language traffic -- not required on every page. For Bing: supplement with <html lang> and <meta http-equiv="content-language"> (Bing treats hreflang as a weak signal).
Canonicalization for Multilingual Sites
- Each locale page must self-canonical (e.g.,
/ar/page canonicals to /ar/page)
- Never cross-locale canonical (French to English) -- suppresses the non-canonical locale entirely
- Canonical URL must appear in the hreflang set -- if not, all hreflang is ignored
- Canonical overrides hreflang when they conflict
- Protocol/domain must be consistent across canonical, hreflang, and sitemap (
https + same domain variant)
- Paginated locale pages: self-referencing canonical per page (never canonical page 2+ to page 1)
Common mistakes: all locales canonical to English (kills indexing), canonical URL not in hreflang set (silently ignored), protocol mismatch between canonical and hreflang, CMS setting deep page canonical to homepage.
International Sitemaps
Check for:
xmlns:xhtml namespace on <urlset>, each <url> includes <xhtml:link> for all locales including itselfx-default alternate included; all URLs absolute (full protocol + domain)- Sitemap index in Search Console and robots.txt; split by content type, not by locale
Next.js caveat: alternates.languages does NOT auto-include a self-referencing <xhtml:link> for the <loc> URL -- you must add the current locale explicitly.
Locale URL Structure
Recommended: Subdirectories (/en/, /ar/). Acceptable: Subdomains or ccTLDs. Not recommended: URL parameters (?lang=en).
Check for:
- Consistent locale prefix strategy; all locales prefixed (hiding locale from URLs prevents Google from distinguishing versions)
- Root URL handled as
x-default with redirect, or serves default locale content
- No IP/Accept-Language content negotiation (Googlebot: US IPs, no Accept-Language header)
- Trailing slash + case consistency across locale paths, canonicals, hreflang, and sitemaps
- 301 redirects from non-canonical format to canonical
Note: Google's International Targeting report in Search Console is deprecated. Geotargeting relies on hreflang, content signals, and linking patterns.
Content Quality Across Locales
Translation quality:
- AI-translated content is not inherently spam (Google's 2025 stance), but scaled low-value translations can trigger scaled content abuse policy
- Google uses visible content to determine language -- translate ALL page content (title, description, headings, body), not just boilerplate
- Translating only template/nav while main content stays in original language creates duplicates
Thin locale pages:
- Helpful content system is site-wide -- many thin locale pages can suppress rankings for strong pages too
- Don't noindex thin locales (wastes crawl budget) or cross-locale canonical (conflicts with hreflang)
- Best approach: don't create locale pages you cannot make genuinely helpful
Check for:
- All locale pages have fully translated main content (not just UI chrome)
- No near-identical content across locales ("Duplicate, Google chose different canonical" in GSC)
- Hreflang only for locales with genuine content and search demand
- Localized signals: currency, phone format, addresses where applicable
- Broken hreflang links (404s, redirects) waste crawl budget AND invalidate hreflang clusters
On-Page SEO Audit
Title Tags
Check for:
- Unique titles for each page
- Primary keyword near beginning
- 50-60 characters (visible in SERP)
- Compelling and click-worthy
- Brand name placement (end, usually)
Common issues:
- Duplicate titles
- Too long (truncated)
- Too short (wasted opportunity)
- Keyword stuffing
- Missing entirely
Meta Descriptions
Check for:
- Unique descriptions per page
- 150-160 characters
- Includes primary keyword
- Clear value proposition
- Call to action
Common issues:
- Duplicate descriptions
- Auto-generated garbage
- Too long/short
- No compelling reason to click
Heading Structure
Check for:
- One H1 per page
- H1 contains primary keyword
- Logical hierarchy (H1 → H2 → H3)
- Headings describe content
- Not just for styling
Common issues:
- Multiple H1s
- Skip levels (H1 → H3)
- Headings used for styling only
- No H1 on page
Content Optimization
Primary Page Content
- Keyword in first 100 words
- Related keywords naturally used
- Sufficient depth/length for topic
- Answers search intent
- Better than competitors
Thin Content Issues
- Pages with little unique content
- Tag/category pages with no value
- Doorway pages
- Duplicate or near-duplicate content
Image Optimization
Check for:
- Descriptive file names
- Alt text on all images
- Alt text describes image
- Compressed file sizes
- Modern formats (WebP)
- Lazy loading implemented
- Responsive images
Internal Linking
Check for:
- Important pages well-linked
- Descriptive anchor text
- Logical link relationships
- No broken internal links
- Reasonable link count per page
Common issues:
- Orphan pages (no internal links)
- Over-optimized anchor text
- Important pages buried
- Excessive footer/sidebar links
Keyword Targeting
Per Page
- Clear primary keyword target
- Title, H1, URL aligned
- Content satisfies search intent
- Not competing with other pages (cannibalization)
Site-Wide
- Keyword mapping document
- No major gaps in coverage
- No keyword cannibalization
- Logical topical clusters
Structured Data
Read the Schema Markup Detection Limitation above before auditing this — a static fetch cannot
see JS-injected JSON-LD, and reporting "no schema found" from curl output is a false finding.
Check for:
- Correct type for the page's purpose (
Article/TechArticle, Product, FAQPage, HowTo, BreadcrumbList, Organization, Person, SoftwareApplication, LocalBusiness)
- Validates without errors in the Rich Results Test
- Markup matches visible page content — invisible or contradictory markup is a spam-policy violation, not an optimization
dateModified present and truthful on content that changes- Entity nodes (
Organization / Person) carry sameAs links to authoritative profiles
@id used consistently so nodes can reference each other instead of being duplicated- One coherent graph per page rather than several disconnected islands
Common issues:
- Required properties missing, so the type is ineligible for rich results
FAQPage markup on content that is not a genuine Q&A- Schema describing content the user cannot see
- Stale
dateModified auto-set to build time on unchanged pages
- Duplicate
Organization nodes on every page with no shared @id
Structured data also has a measurable association with citation in generative answers — see the
GEO section.

User Engagement Signals — diagnostic only, not ranking factors
Google does not use analytics engagement metrics as ranking factors. John Mueller: "We don't use
bounce rate in search rankings." Gary Illyes: "we don't use analytics/bounce rate in search
ranking." Google has denied this for roughly a decade.
Never write a finding that says "improve bounce rate to improve rankings" — it is a causal claim
Google has explicitly denied, and it damages the credibility of the correct findings next to it.
Use these metrics the other way round: as diagnostics that localize a content problem, whose fix
is the content itself.
| Metric | Read it as |
|---|
| High exit rate on a ranking page | Possible intent mismatch — the page ranks for a query it does not answer |
| Very low time on page for long-form content | Content may be unscannable, or the answer is buried |
| Pages per session | Internal linking and topical-cluster coverage signal |
| Return visits | Brand and content-quality signal (correlates with, does not cause, ranking) |
Generative Engine Optimization (GEO)
Visibility inside AI-generated answers — Google AI Overviews / AI Mode, ChatGPT, Claude, Perplexity —
rather than in a ranked list of links. See the GEO reference for the measured
evidence, source tiers, and the full AI-crawler agent table.
GEO layers on top of ranking; it does not replace it. Roughly three quarters of AI Overview
citations come from pages already in the top 10. Audit the priority order first.
What measurably works
Peer-reviewed measurement (GEO-bench, KDD 2024: ~10,000 queries across nine datasets) found the
largest visibility gains come from evidence, not markup:
| Finding to raise | Measured effect |
|---|
| Claims lack verifiable statistics with named sources | ~30–40% gain when added |
| No credible quotations where the topic supports them | ~30–40% |
| No outbound citations to reliable sources | ~30–40% |
| Poor fluency / readability | ~15–30% |
| Keyword stuffing present | Negligible or negative — treat as a defect, not a tactic |
Gains are largest for content that is visible but not dominant (up to +115.1% at position 5), which
is most audit subjects.
The self-containment test
Generative engines extract passages, not pages. For each passage the page wants cited, ask:
does this paragraph still make sense lifted out with no surrounding context?
Anaphora that depends on the previous paragraph ("this approach", "as mentioned above", "the former")
breaks extraction. This is the most common GEO defect on otherwise well-optimized pages, and no
classic on-page check catches it.
Also require: a definitional sentence ("X is a Y that does Z.") at first use of every term the
page wants to own, and a Q&A block with the question as the heading and the direct answer in the
first sentence.
Checks
Do not raise these
- Missing
llms.txt. Adoption is ~8.7% of the top 1,000 domains, ~40% of existing files are
empty plugin stubs, no major AI crawler has committed to consuming it, crawler logs show the
retrieval agents skip it, and in one citation model removing the variable improved accuracy. It
has a legitimate use as business-to-agent context for IDE agents and MCP servers — recommend it on
developer-experience grounds or not at all, never as a visibility tactic.
- "Improve bounce rate to rank better." See User Engagement Signals above.

AKILI-SPECS Integration
| AKILI moment | How to use this skill |
|---|
/akili-seo audit phase | Required skill — load before starting and apply throughout; the Audit Report Structure above is the finding format |
/akili-validate | When validating pages with search-visibility requirements, apply the On-Page checklist to the affected routes |
Adaptation rules:
- Findings land in the AKILI report artifacts (
/akili-seo output), using the Issue / Impact / Evidence / Fix / Priority shape.
- Fixes that exceed the trivial gate are routed through
/akili-propose — never applied silently during the audit.
- GEO findings use the same Issue / Impact / Evidence / Fix / Priority shape. Label the source tier when citing a magnitude: the KDD 2024 figures are peer-reviewed, the AI Overview and crawler-behaviour figures are industry analyses. Never present an
[INDUSTRY] number to a client as measured fact.
- Sibling skills mentioned by upstream versions of this skill (programmatic-seo, cro, analytics) are not packaged with AKILI-SPECS; when a finding needs them, note the gap in the report instead of loading them. The upstream
schema and ai-seo gaps are now covered in-skill by the Structured Data and GEO sections.
