technical-seo-checker

What This Skill Does

The technical-seo-checker is a comprehensive diagnostics tool designed to audit the foundational health of a website. It systematically evaluates critical performance and accessibility metrics, including Core Web Vitals (LCP, CLS, INP, TTFB), crawlability, indexability, mobile responsiveness, and security protocols like HTTPS. Beyond basic checks, it validates structured data (Schema) to ensure search engines can parse content properly and identifies potential roadblocks such as broken redirect chains, suboptimal robots.txt configurations, or mismanaged hreflang tags. The output is a professional-grade audit report featuring a health score from 0 to 100, a prioritized list of issues categorized by impact (Critical, High, Medium), and an actionable implementation roadmap to optimize search visibility.

Installation

To integrate this skill into your OpenClaw environment, use the command-line interface as follows: clawhub install openclaw/skills/skills/aaron-he-zhu/technical-seo-checker Ensure your system meets the dependencies listed in the main documentation repository to allow the agent to reach the required diagnostic APIs.

Use Cases

This skill is essential for site owners, developers, and SEO professionals alike. Use it during the pre-launch phase of a website to catch configuration errors before they affect indexing. It is also a primary tool for troubleshooting sudden traffic drops, performing pre-migration audits when switching domains or CMS platforms, and conducting recurring site health checks to maintain Core Web Vitals compliance. It is particularly effective at identifying JavaScript rendering issues that often plague modern single-page applications.

Example Prompts

1. "Perform a full technical SEO audit for https://example-shop.com to identify why our crawl budget is being wasted."
2. "My site has severe CLS problems on mobile; please audit the layout stability and suggest fixes."
3. "Run a health check on my domain for indexing issues, specifically looking for canonical tag conflicts and robots.txt errors."

Tips & Limitations

For optimal results, ensure the target domain allows the agent's user agent to crawl the site. This skill is intended for technical auditing; for site architecture and internal link pathing, pair it with the internal-linking-optimizer skill. Note that while this provides automated, data-driven insights, manual verification is always recommended for complex enterprise-level migrations or high-traffic domains where server-side log analysis may be required.
