At a glance
Reviews one URL for on-page SEO, content quality, technical metadata, schema, images and performance, using concrete length and size thresholds.
- Reviewing the SEO of one landing page or blog post
- SKILL.md covers What to Analyze, Output, DataForSEO Integration… and Error Handling
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Checking title, meta description and heading structure before publishing
What it does
The agent checks one page against a fixed list. On-page items include a title of 50 to 60 characters, a meta description of 150 to 160 characters, a single H1, a clean heading hierarchy, a short URL and sensible internal and external links. A script compares the title and description to catch templated metadata, such as a description that repeats the title and ends on a stock call to action.
Content checks cover word count by page type, readability, natural keyword density, author and experience signals and freshness. Technical checks cover the canonical tag, meta robots, Open Graph, Twitter Card and hreflang. Schema is detected and validated, and HowTo and FAQ rich results are no longer recommended. Images are flagged for missing alt text, file size over 200KB as a warning and over 500KB as critical, format and dimensions, with JavaScript lazy-loaders recognized so they are not falsely flagged.
When your agent uses it
- Reviewing the SEO of one landing page or blog post
- Checking title, meta description and heading structure before publishing
- Validating schema markup and Open Graph tags on a single URL
- Spotting oversized or poorly lazy-loaded images on a page
Example prompts
- “Analyze https://example.com/blog/launch for on-page SEO and list the fixes.”
- “Check the title, meta description and H1 on our pricing page.”
- “Which images on this URL are too heavy, and what format should they use?”
Requirements
- The claude-seo plugin scripts, for the metadata comparison
What it can do on your machine
Read from SKILL.md and the folder at commit 4b99de2. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Single Page SEO Analysis loads about 1.1k tokens when it runs. Until then it costs about 37 tokens; SKILL.md has 469 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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
- Meta description is not a restatement of the title: run
"${CLAUDE_PLUGIN_ROOT}/scripts/claude-seo" run metadata_template.py --title "<title>" --description "<desc>" --json(heuristic, deterministic string comparison). A description that opens by repeating its own title and closes on a stock CTA ("Try it free now.", "Start free!") is templated metadata, the shape bulk generation jobs produce site-wide, and duplicated or templated metadata is a documented content-quality problem regardless of how original the body copy is - 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); existing FAQPage need not be removed, 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_methodper 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 nativeloading="lazy"attribute and usedata-srcplaceholders
Show full SKILL.md (171 more words)Show less
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. |
