SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Auditing a single web page for SEO issues requires checking dozens of elements manually, from title tags and heading hierarchy to schema markup and image optimization. This Skill performs a structured deep analysis of one URL and returns a scored report with prioritized issues and actionable fixes. ## Core Features & Use Cases - On-Page and Content Audit: Checks title tags, meta descriptions, heading hierarchy, internal links, word count, readability, keyword density, and E-E-A-T signals. - Technical and Schema Review: Validates canonical tags, meta robots, Open Graph, Twitter Cards, hreflang, and JSON-LD schema, and generates ready-to-use schema suggestions. - Image and Performance Flags: Detects missing alt text, oversized images, lazy-loading methods, and potential Core Web Vitals issues like LCP, INP, and CLS risks. - Use Case: A content marketer pastes a blog post URL before publishing and receives a page score card, a prioritized issue list from critical to low, and copy-paste JSON-LD schema for missing markup. ## Quick Start Ask the AI to analyze the SEO of the page at https://example.com/my-article and report issues by priority.

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

Provide the page URL and the analysis covers title tags, meta descriptions, heading hierarchy, internal links, content quality, schema markup, and images. The output is a score card out of 100 plus issues organized by priority from critical to low.

What does a single page SEO audit include?

A single page audit covers on-page elements like titles and headings, content quality metrics like readability and keyword density, technical tags like canonical and Open Graph, JSON-LD schema validation, and image checks for alt text, file size, and lazy loading.

Can SEO analysis detect JavaScript-rendered content issues?

When a page renders content client-side, the analysis works on the available HTML and flags that results may be incomplete. It suggests providing a browser-rendered snapshot when key content is missing from the raw HTML.

Does the page audit handle unreachable or authenticated URLs?

If a URL is unreachable due to DNS failure or connection refusal, the error is reported without guessing page content. For 401 or 403 responses, it reports the authentication requirement and suggests providing rendered HTML or a public URL.

What schema markup types are recommended for rich results?

The analysis detects existing JSON-LD types, validates required properties, and suggests missing opportunities. It avoids recommending deprecated HowTo or FAQ rich results and suggests QAPage for genuine question-and-answer content.
