# Skill: SEO Audit (Cross-Cutting)
## Purpose
Run a comprehensive SEO audit — keyword research, on-page analysis, content gaps, technical checks, and competitor comparison to generate a prioritized SEO action plan.
## When to Use
- When assessing a website's overall SEO health and indexation status.
- When researching keyword opportunities and identifying high-volume, low-difficulty search queries.
- When identifying content gaps where competitors rank higher.
- When reviewing technical website issues (crawlability, page speed, structured schema data).
## Step-by-Step Process
### Step 1: Keyword & Competitor Research
- Extract primary and secondary keywords relevant to the business/domain.
- Group keywords by search intent (informational, navigational, commercial, transactional).
- Identify top 2-3 organic competitors.
### Step 2: On-Page SEO Analysis
- Verify title tag length (50-60 chars) and meta description length (150-160 chars).
- Confirm presence of exactly one H1 tag per page.
- Evaluate subheading hierarchy (H2/H3) and keyword usage.
- Assess image alt text and URL clean structure.
### Step 3: Content Gap & Freshness Review
- Detect topics covered by competitors but missing on the site.
- Identify pages with thin content (<300 words) or content older than 12 months.
### Step 4: Technical SEO Audit
- Review Robots.txt and XML sitemap configurations.
- Check canonical tags, HTTPS mixed content, and 404 broken links.
- Review Page Speed and Core Web Vitals (LCP, INP, CLS) markers.
### Step 5: Prioritized Action Plan Formulation
- Group recommendations into "Quick Wins" (<2h effort, high impact) and "Strategic Investments" (long-term, pillar pages).

- **Audit Type**: Full site audit, keyword research, content gap, or technical SEO check.

## Expected Output

- **On-Page Issues Table**: Issues categorized by Severity (Critical, High, Medium, Low).
- **Technical SEO Checklist**: Status (Pass, Fail, Warning) of crawlability, speed, and schema.
- **Prioritized Action Plan**: Split into Quick Wins and Strategic Investments.
## Tone & Rules
- Write in a professional, marketing-focused, data-driven tone.
