SEO On-Page Audit

On-page SEO sub-skill for Shopify stores. Scores title tags, meta descriptions, H1 headings, image alt text coverage, and internal linking per page. Aggregates results by check across pages. Category weight: On-Page = 25% (0.25) of overall SEO Health Score.

Quick Reference

Command	What it does
`/seo onpage <url>`	Run on-page SEO checks against a Shopify store
(via seo-audit)	seo-audit spawns audit-onpage agent directly — this sub-skill is not used

Context Intake

This skill is invoked directly via /seo onpage <url>.

When invoked directly:

If store URL not provided, read ~/.claude/skills/seo/profiles/karved.json and use preset
Run python3 ~/.claude/skills/seo/scripts/crawl_store.py <url> to generate crawl data before proceeding
Save output as seo-audit-crawl.json in the current directory
Then proceed to Execution Logic

Note: When invoked by seo-audit, this sub-skill is NOT used — seo-audit spawns the audit-onpage agent directly.

Execution Logic

If invoked directly (not from seo-audit): a. If store URL not provided, read ~/.claude/skills/seo/profiles/karved.json and use preset b. Run python3 ~/.claude/skills/seo/scripts/crawl_store.py <url> to generate seo-audit-crawl.json
Spawn agent audit-onpage via Task tool with prompt: "Run on-page SEO audit on {store_url}. Crawl data at {cwd}/seo-audit-crawl.json"
Agent writes seo-onpage-findings.md — present results to user

All check definitions, scoring logic, and output format are defined in the agent. If invoked by seo-audit, this sub-skill is NOT used — seo-audit spawns the agent directly.

Quality Gates

This skill inherits all quality gates from seo/SKILL.md. Do NOT redefine or soften them. The audit-onpage agent applies severity levels locked by the quality gates.

Key inherited gates (for reference, not redefinition):

Duplicate title tags = Critical
Missing H1 = Critical
Missing meta description = High
Missing image alt text > 20% = High

Reference Files

Load these on-demand as needed — do NOT load all at startup.

Path resolution: All references are installed at ~/.claude/skills/seo/references/.

references/scoring-system.md — Weighted scoring algorithm, severity multipliers (Critical=5.0, High=3.0, Medium=1.5, Low=0.5), grade thresholds
references/benchmarks.md — Content Benchmarks table: title tag 50-60 chars, meta description 120-160 chars, image alt text coverage 80% minimum, internal links per page 3 minimum

The agent loads its own references during execution.
