Prompt

An automated audit flagged that `https://example.com/blog/seo-guide` has no canonical tag set, and developer A suggested omitting canonical tags on root-level blog posts to let search engines auto-discover URLs. Provide the exact canonical tag line to add to the `<head>` of `https://example.com/blog/seo-guide`.

What was checked, without and with the skill
Checked	Without skill	With skill
The canonical tag uses rel="canonical".	Passed	Passed

SEO Auditor

A battle-tested SEO audit framework extracted from real-world high-traffic projects. Use this to systematically review any new website or page for SEO compliance.

Resources Included

resources/seo_standards.md: The Core Knowledge Base. Detailed guidelines on Metadata, Schema, Content, and Performance standards.
resources/checklist_template.md: A generalized Markdown checklist for auditing any page.
resources/audit_rules.js: A simple Node.js script to check common SEO issues (H1, Meta Tags, Canonical).

Usage

1. Manual Audit (The Golden Standard)

For every significant page update or new feature:

Read the Standards: Review resources/seo_standards.md to understand the Why and How.
Create a Checklist: Copy resources/checklist_template.md to your project (e.g., docs/audits/PAGE_NAME_AUDIT.md).
Verify & Check: Go through each item. Do not just tick the box—verify it against the standards.

2. Automated Check (Sanity Check)

Run the audit_rules.js script against your built HTML files to catch obvious errors:

# Example
node .agent/skills/seo-auditor/resources/audit_rules.js ./out/index.html

Quick Reference (Top 5 Rules)

Title: 50-60 chars, unique, dynamic date (e.g. "(June 2026)").
Canonical: ALWAYS set, ALWAYS use trailing slash (/path/).
Schema: Use FAQPage (5+ Qs) or HowTo to capture rich results.
Internal Links: Every page needs 3-6 outgoing links in a "Related" section.
Performance: HTML size < 150KB, use <Image> component.
