What is SEO Analyzer?
The SEO Analyzer is a specialized utility designed to bridge the gap between development and search engine optimization. As a lightweight yet powerful addition to Openclaw Skills, it performs deep scans of HTML content to identify critical SEO failures. It checks everything from title tag length and meta descriptions to heading hierarchy and social metadata, ensuring your web pages are fully optimized for search engine visibility and user experience.
This tool is particularly valuable for developers who want to integrate SEO checks directly into their workflow. By utilizing standard Unix utilities, it provides a fast and dependency-free way to audit content without needing heavy browser-based tools. It represents a core part of the Openclaw Skills ecosystem for technical marketing and frontend health.
SEO Analyzer Use Cases
- Running quick SEO audits on new landing pages before deployment.
- Automating the detection of missing image alt tags and social metadata.
- Validating heading structures to ensure accessibility and SEO compliance.
- Performing keyword density analysis to verify content focus.
- Checking for canonical URL implementation to prevent duplicate content penalties.
How SEO Analyzer Works
- The user provides a target URL or pipes raw HTML content into the analyzer script.
- The skill utilizes curl or web_fetch to retrieve the source code of the specified webpage.
- The tool parses the HTML using grep, sed, and awk to extract metadata, headings, and body content.
- It evaluates the extracted data against SEO best practices, such as character limits and tag counts.
- A plain text report is generated, highlighting findings and offering prioritized recommendations for the user.
SEO Analyzer Setup
To get started with this component of Openclaw Skills, ensure you have curl and standard Unix tools (grep, sed, awk) available in your environment.
# Make the script executable
chmod +x seo-analyze.sh
# Run a direct analysis on a URL
./seo-analyze.sh https://example.com
# Or pipe content from curl
curl -sL https://example.com | ./seo-analyze.sh -
