Assesses content quality including word count, readability, keyword density, and E-E-A-T signals
Checks technical elements like canonical tags, meta robots, Open Graph, Twitter Cards, and hreflang
Detects and validates schema markup (JSON-LD preferred) with recommendations for missing opportunities
Analyzes images for alt text, file size, format, dimensions, and lazy-loading implementation
Flags potential Core Web Vitals issues (LCP, INP, CLS) based on HTML structure

seo-page FAQ

What if the page requires authentication or is behind a login?

Report the authentication requirement. You can provide the rendered HTML directly or use a publicly accessible URL instead.

Can this analyze JavaScript-rendered content?

The skill analyzes available HTML. If key content is rendered client-side, results may be incomplete. Suggest using a browser-rendered snapshot for more accurate analysis.

Does this check actual search rankings and backlinks?

Not by default, but if DataForSEO MCP tools are available, the skill can fetch real SERP positions and backlink data.

What's the difference between recommended schema types?

The skill avoids deprecated HowTo and retired FAQ rich results (as of May 2026), but keeps FAQPage as an AI-citation signal and recommends QAPage for genuine Q&A content.

How does it handle images that use JavaScript lazy-loading?

The skill recognizes JS lazy-loaders (Perfmatters, EWWW, lazysizes) and does not flag them as unoptimized, since they intentionally use data-src placeholders instead of native loading attributes.

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.
