    SEO Health Check

    Example session with this skill installed

    Run a health check on index.html using the keyword 'headless cms'.

    • Read your context and instructions
    • Compiled the seo health check
    • Generated the document

    I have analyzed index.html for the keyword 'headless cms' and identified several critical SEO gaps.

    SEO Health Audit: index.html

    Verdict: Needs Work

    RiskDimensionFindingRequired Action
    HighTitle TagTitle is 'Home' and does not contain the keyword.Change title to include 'Headless CMS' (e.g., 'What is a Headless CMS?
    HighMeta DescriptionMeta description is missing entirely.Add a <meta name="description"> tag between 120-160 characters.
    MediumHeadingsH1 tag found but does not contain the target keyword.Update H1 from 'Welcome to our blog' to 'Modern Headless CMS Solutions'.
    MediumLinks12 external links found, 0 internal links found.Add at least 2 internal links to other pages on your domain to retain link equity.
    LowKeyword DensityKeyword appears 1 time in body text (0.1% density).Naturally include 'headless cms' 2-3 more times in the body paragraphs.

    Next steps

    1. Immediate: Add the missing meta description to resolve the High-risk warning.
    2. Structural: Rename the H1 tag to include 'headless cms' to improve semantic relevance.
    3. Internal Linking: Add a 'Related Posts' section or link to your pricing page to fix the internal link deficit.

    About this skill

    The problem

    Vague SEO advice doesn't help developers fix broken pages. You need to know exactly which tags are missing or poorly optimized on a specific local file before it goes live.

    What it does

    • Analyzes local HTML files for keyword density in titles, descriptions, and headings.
    • Validates meta description length and click-through appeal.
    • Audits heading hierarchy and keyword placement within H1 tags.
    • Evaluates internal versus external link ratios and anchor text quality.
    • Generates a risk-graded report (High/Medium/Low) based on measured page data.

    Frameworks & tools

    Works with any standard HTML5 file. The underlying logic uses a zero-dependency Python script compatible with the standard library.

    Why this beats prompting it yourself

    Generic LLM prompts often hallucinate SEO best practices or miss technical details in long HTML files. This skill enforces a structured audit against specific dimensions like internal link counts and exact keyword placement, ensuring every suggestion is backed by a measured value rather than a guess.

    Use cases

    • Pre-deployment audits for landing pages and blog posts.
    • Benchmarking local development builds against target keywords.
    • Identifying critical accessibility and SEO blockers in raw HTML exports.
    • Verifying link structures and heading hierarchies during a site migration.

    Known limitations

    Requires the page to be saved as a local .html file. It cannot crawl live URLs or execute JavaScript-heavy client-side rendering during the audit.
