SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Manually auditing a web page for SEO issues is slow and error-prone, requiring checks across dozens of on-page, technical, and content factors. This Skill performs a structured single-page SEO analysis and produces a scored report with prioritized issues and actionable recommendations. ## Core Features & Use Cases - On-Page SEO Audit: Checks title tags, meta descriptions, heading hierarchy, URL structure, and internal/external links against best-practice rules. - Technical & Schema Validation: Inspects canonical tags, meta robots, Open Graph, Twitter Cards, hreflang, and JSON-LD schema, then generates ready-to-use schema markup for detected opportunities. - Content & Image Quality Review: Evaluates word count, readability, keyword density, E-E-A-T signals, image alt text, file sizes, and lazy loading. - Use Case: Paste a blog post URL before publishing to get a 100-point score card, a prioritized issue list (Critical to Low), and specific fixes with expected impact. ## Quick Start Analyze the SEO of https://example.com/my-article and give me the score card with prioritized recommendations.

Frequently Asked Questions about seo-page

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

FAQPage Schema
How do I check the SEO of a single web page?▼

Provide the page URL and the Skill fetches the HTML, then audits title tags, meta descriptions, headings, links, schema, and images. It returns a score card out of 100 plus issues organized by priority from Critical to Low.

What on-page SEO factors does a page audit check?▼

The audit covers title tag length and keywords, meta description, H1 uniqueness, heading hierarchy, URL structure, internal and external links, canonical tags, Open Graph, Twitter Cards, hreflang, and JSON-LD schema markup.

Can SEO analysis work on JavaScript-rendered pages?▼

Analysis of JavaScript-rendered pages is limited because the fetched HTML may have an empty body. The Skill analyzes available HTML, flags that results may be incomplete, and suggests providing a browser-rendered snapshot.

Why does page SEO analysis fail on some URLs?▼

Analysis fails when the URL is unreachable due to DNS or connection errors, or when the page returns 401/403 authentication errors. In those cases the Skill reports the error and asks for a valid public URL or the rendered HTML directly.

Does the audit recommend FAQ or HowTo schema markup?▼

No, the Skill never recommends HowTo schema because it is deprecated, and avoids FAQ schema because Google restricts it to government and health sites. It suggests other valid JSON-LD types matching the detected page content.
