seo-page is an agent skill that performs deep single-URL SEO analysis across on-page elements, content quality, technical meta tags, schema, images, and performance signals with scored recommendations.

About

seo-page is an agent skill for deep single-URL SEO analysis when a user provides one page to review rather than a full-site crawl. It scores On-Page SEO, Content Quality, Technical elements, Schema, and Images in a Page Score Card, then lists issues from Critical through Low with actionable recommendations and ready-to-use JSON-LD suggestions. Checks include title length 50-60 characters, meta description 150-160 characters, a single intent-aligned H1, heading hierarchy, canonical and robots tags, Open Graph and Twitter Card completeness, and image alt text with lazy loading method detection that respects Perfmatters, EWWW, and similar JS loaders. Schema guidance flags deprecated HowTo and retired FAQ rich results while keeping FAQPage as an AI citation signal and recommending QAPage for genuine Q and A. Optional DataForSEO MCP tools can add SERP positions and backlink context. Error handling covers unreachable URLs, authentication walls, and JavaScript-rendered pages without guessing missing content.

Produces a five-category Page Score Card with prioritized Critical through Low issue lists.
Audits title, meta, H1, heading hierarchy, canonical, robots, Open Graph, and Twitter Card tags.
Detects schema types, validates required properties, and outputs ready JSON-LD suggestions.
Flags image size thresholds, format recommendations, and JS lazy-loader methods without false positives.
Never recommends deprecated HowTo or FAQ rich results; keeps FAQPage as an AI citation signal.

Single Page Analysis

What to Analyze

On-Page SEO

Title tag: 50-60 characters, includes primary keyword, unique
Meta description: 150-160 characters, compelling, includes keyword
H1: exactly one, matches page intent, includes keyword
H2-H6: logical hierarchy (no skipped levels), descriptive
URL: short, descriptive, hyphenated, no parameters
Internal links: sufficient, relevant anchor text, no orphan pages
External links: to authoritative sources, reasonable count

Content Quality

Word count vs page type minimums (see quality-gates.md)
Readability: Flesch Reading Ease score, grade level
Keyword density: natural (1-3%), semantic variations present
E-E-A-T signals: author bio, credentials, first-hand experience markers
Content freshness: publication date, last updated date

Technical Elements

Canonical tag: present, self-referencing or correct
Meta robots: index/follow unless intentionally blocked
Open Graph: og:title, og:description, og:image, og:url
Twitter Card: twitter:card, twitter:title, twitter:description
Hreflang: if multi-language, correct implementation

Schema Markup

Detect all types (JSON-LD preferred)
Validate required properties
Identify missing opportunities
NEVER recommend HowTo (deprecated) or FAQ for rich results (retired May 2026); keep existing FAQPage as an AI-citation signal, use QAPage for genuine Q&A

Images

Alt text: present, descriptive, includes keywords where natural
File size: flag >200KB (warning), >500KB (critical)
Format: recommend WebP/AVIF over JPEG/PNG
Dimensions: width/height set for CLS prevention
Lazy loading: report lazy_method per image (native | perfmatters | ewww | js-generic | none). Do not flag "not lazy-loaded" when JS lazy-loaders (Perfmatters, EWWW, lazysizes) are detected — they intentionally strip the native loading="lazy" attribute and use data-src placeholders

Core Web Vitals (reference only, not measurable from HTML alone)

Flag potential LCP issues (huge hero images, render-blocking resources)
Flag potential INP issues (heavy JS, no async/defer)
Flag potential CLS issues (missing image dimensions, injected content)

Error Handling

Scenario	Action
URL unreachable (DNS failure, connection refused)	Report the error clearly. Do not guess page content. Suggest the user verify the URL and try again.
Page requires authentication (401/403)	Report that the page is behind authentication. Suggest the user provide the rendered HTML directly or a publicly accessible URL.
JavaScript-rendered content (empty body in HTML)	Note that key content may be rendered client-side. Analyze the available HTML and flag that results may be incomplete. Suggest using a browser-rendered snapshot if available.
