SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) components.

What problem does it solve? Web pages often ship with missing meta tags, broken heading hierarchy, or images lacking alt text, hurting search rankings. This Skill provides SEO best-practice guidance and an automated checker that scans HTML, JSX, and TSX page files for common on-page SEO issues. ## Core Features & Use Cases - SEO Knowledge Base: Reference tables covering E-E-A-T, Core Web Vitals targets, schema markup types, title/meta length rules, and prioritized ranking factors. - Automated Page Audit: The seo_checker.py script scans a project for page files and reports missing titles, meta descriptions, Open Graph tags, multiple H1s, and images without alt attributes. - Use Case: Before launching a Next.js site, run the checker against the project to find pages missing meta descriptions or OG tags, then fix them using the content SEO guidelines. ## Quick Start Run the SEO checker script on my project directory and list all pages with missing meta descriptions or alt attributes.

Frequently Asked Questions about seo-fundamentals

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I check my website pages for SEO issues?▼

Run the seo_checker.py script against your project directory. It scans HTML, JSX, and TSX page files and reports missing titles, meta descriptions, Open Graph tags, multiple H1 headings, and images lacking alt attributes.

What are the Core Web Vitals targets for good SEO?▼

Google's Core Web Vitals targets are LCP under 2.5 seconds for loading performance, INP under 200 milliseconds for interactivity, and CLS under 0.1 for visual stability. Meeting these thresholds supports better page experience rankings.

Does the SEO checker work with React and Next.js projects?▼

Yes, the checker scans JSX and TSX files in pages, app, routes, views, and screens directories, which covers React and Next.js project structures. It skips utility, config, test, and node_modules files to focus on public-facing pages.

Why does Google penalize AI-generated content?▼

Google does not penalize AI content itself but demotes low-value content lacking original insight. The recommended approach is AI drafting combined with human editing, expert review, fact-checking, and adherence to E-E-A-T principles.

What are the limitations of automated SEO checking?▼

The script checks only static on-page elements in up to 50 page files and cannot measure actual rankings, backlinks, or real Core Web Vitals performance. Use Search Console, PageSpeed Insights, and analytics tools for those metrics.
