Technical SEO Checker

Overview

Technical SEO Checker is the skill of auditing the site conditions that determine whether good pages can actually be crawled, indexed, and trusted. For a one-person company, technical SEO should stay simple and ruthless: remove blockers, stabilize canonical paths, keep performance acceptable, and avoid avoidable crawl waste.

When to Use This Skill

Use this before and after major releases, when rankings drop unexpectedly, when answer-engine visibility falls despite strong content, or when you suspect crawl or canonical problems are distorting performance.

What This Skill Does

This skill helps you check the few technical layers that actually matter for a lean content site: robots, sitemap, canonicals, redirects, indexability, basic performance, and structured data sanity.

Output

The output should include:

• A list of blockers by severity
• Affected URLs or patterns
• The fix recommendation
• Whether the issue affects crawl, index, traffic, or citations

Common Mistakes

Do not run a huge checklist without prioritizing impact. Do not spend weeks on micro-optimizations while canonical and redirect issues stay broken. Do not create multiple public URLs for the same page. Do not treat sitemap presence as proof that a page is healthy.
