Audit a website's SEO health, research keyword opportunities, identify content gaps, and benchmark against competitors. Produces a prioritized action plan a marketer can execute immediately.

## Trigger

User runs `/seo-audit` or asks for an SEO audit, keyword research, content gap analysis, technical SEO check, or competitor SEO comparison.

## Inputs

Gather the following from the user. If not provided, ask before proceeding:

1. **URL or domain** — the site to audit, or a topic/keyword if running in keyword research mode

2. **Audit type** — one of: - **Full site audit** — end-to-end SEO review covering all sections below - **Keyword research** — identify keyword opportunities for a topic or domain - **Content gap analysis** — find topics competitors rank for that you don't - **Technical SEO check** — crawlability, speed, structured data, and infrastructure issues - **Competitor SEO comparison** — head-to-head SEO benchmarking against specific competitors

If not specified, default to **full site audit**.

3. **Target keywords or topics** (optional) — specific keywords the user is already targeting or wants to rank for

4. **Competitors** (optional) — domains or companies to compare against. If not provided and the audit type requires competitor data, use web search to identify 2-3 likely competitors based on the user's domain and keyword space.

## Process

### 1. Keyword Research

Research keywords related to the user's domain, topic, or target keywords.

**If ~~SEO tools are connected:** - Pull keyword data, search volume, keyword difficulty scores, and ranking positions automatically - Identify keywords the site currently ranks for and where it's gaining or losing ground

**If ~~product analytics are connected:** - Cross-reference keyword targets with actual organic traffic data to validate which keywords are driving visits and conversions

**If tools are not connected:** - Use web search to research the keyword landscape - Note: "For more precise volume and difficulty data, connect an SEO tool like Ahrefs or Semrush via MCP. The audit will auto-populate with ranking data."

For each keyword opportunity, assess: - **Primary keywords** — high-intent terms directly tied to the user's product or service - **Secondary keywords** — supporting terms and variations - **Search volume signals** — relative demand (high, medium, low) based on available data - **Keyword difficulty** — how competitive the term is (easy, moderate, hard) - **Long-tail opportunities** — specific, lower-competition phrases with clear intent - **Question-based keywords** — "how to", "what is", "why does" queries that mirror People Also Ask results - **Intent classification** — informational, navigational, commercial, or transactional

### 2. On-Page SEO Audit

For each key page (homepage, top landing pages, recent blog posts), evaluate:

- **Title tags** — present, unique, within 50-60 characters, includes target keyword - **Meta descriptions** — present, compelling, within 150-160 characters, includes a call to action - **H1 tags** — exactly one per page, includes primary keyword - **H2/H3 structure** — logical hierarchy, uses secondary keywords where natural - **Keyword usage** — primary keyword appears in the first 100 words, used naturally throughout, not over-stuffed - **Internal linking** — pages link to related content, orphan pages identified, anchor text is descriptive - **Image alt text** — all images have descriptive alt attributes, keywords included where relevant - **URL structure** — clean, readable, includes keywords, no excessive parameters or depth

### 3. Content Gap Analysis

Identify what's missing from the user's content strategy:

- **Competitor topic coverage** — topics and keywords competitors rank for that the user's site does not cover - **Content freshness** — pages that haven't been updated in 12+ months and may be losing rankings - **Thin content** — pages with insufficient depth to rank (under 300 words for informational queries, lacking substance) - **Missing content types** — formats competitors use that the user doesn't (guides, comparison pages, glossaries, tools, templates) - **Funnel gaps** — missing content at specific buyer journey stages (awareness, consideration, decision) - **Topic clusters** — opportunities to build pillar pages with supporting content

### 4. Technical SEO Checklist

Evaluate technical foundations that affect crawlability and rankings:

- **Page speed** — identify slow-loading pages and likely causes (large images, render-blocking scripts, excessive redirects) - **Mobile-friendliness** — responsive design, tap targets, font sizes, viewport configuration - **Structured data** — opportunities for schema markup (FAQ, HowTo, Product, Article, Organization, Breadcrumb) - **Crawlability** — robots.txt configuration, XML sitemap
