SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve? Manually checking every page of a site for missing titles, broken meta tags, and invalid structured data is slow and error-prone. This Skill performs a systematic SEO pass over a site's pages, reporting file-and-line findings for on-page elements and Schema.org JSON-LD without changing anything until you approve fixes. ## Core Features & Use Cases - On-page audit: Checks titles, meta descriptions, heading hierarchy, links, images, Open Graph, and Twitter Card tags against documented criteria. - Schema.org validation: Detects JSON-LD, Microdata, and RDFa markup, validates required properties, and flags deprecated types like HowTo, FAQPage, and VehicleListing with current replacement guidance. - Ready-to-use templates: Ships JSON-LD templates for VideoObject, Product, ProductGroup, ProfilePage, ItemList, and more, with placeholders clearly marked for user-supplied facts. - Use Case: Point it at a static site's HTML output and receive a prioritized findings report where every defect names the file, line, and fix, with clean pages explicitly accounted for. ## Quick Start Run an SEO pass over all HTML pages in this repository and report on-page and schema findings ranked by search impact.

Frequently Asked Questions about seo-lite

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

FAQPage Schema
How do I audit all pages of a static site for SEO issues?▼

List the site's HTML files from disk, then check each page against on-page criteria covering titles, meta descriptions, headings, links, images, and Open Graph tags. Report one finding per defect with the file, line, and fix, and account for every page including clean ones.

How do I validate Schema.org JSON-LD markup on my pages?▼

Scan page source for JSON-LD script tags, Microdata, and RDFa, then validate required properties per type against Google's supported rich results. Check for missing @context, relative URLs, invalid dates, and placeholder text before presenting corrected JSON-LD.

Which Schema.org types are deprecated by Google?▼

HowTo lost rich results in September 2023, and FAQ rich results retired for all sites in May 2026. VehicleListing, ClaimReview, EstimatedSalary, LearningVideo, and CourseInfo retired in June 2025, with SpecialAnnouncement deprecated in July 2025.

Should I use JSON-LD, Microdata, or RDFa for structured data?▼

Use JSON-LD, since Google's documentation explicitly recommends it over Microdata and RDFa. Include it in the initial server-rendered HTML rather than injecting it via JavaScript, especially for time-sensitive Product and Offer markup.

Does this SEO audit modify my site files automatically?▼

No, the audit only reports findings and changes nothing until you pick what to fix. Facts like business names, prices, and dates come from your site's own files or from you, with unsourced values left as marked placeholders.
