What its author says it does

Copied from the file, not written here

Crawl any website and produce a graded SEO diagnosis — on-page (title, meta, headings, canonical, mobile viewport, image alt, thin content), technical (HTTPS, robots.txt, sitemap.xml, broken internal links, duplicate titles/meta, near-orphan pages), and structured data (JSON-LD / Schema.org validity and required fields). Zero config, no API keys, pure Python standard library. Use when the user wants to audit, diagnose, check, or review a website's SEO, find SEO problems, or asks "how is my site's SEO / 帮我诊断这个网站的SEO".

Website SEO Audit （网站SEO诊断）

Diagnose any website's SEO by crawling it and checking dozens of on-page, technical, and structured-data signals. No API keys, no setup, no third-party packages — it runs on the Python standard library alone.

When to use this skill

The user asks to audit / diagnose / check / review a website's SEO.
The user shares a URL and asks what's wrong with it for search.
The user wants a before/after SEO comparison, or a report they can act on.

How to run

From this skill's directory:

python3 -m seo_audit https://example.com

If you're calling it from another working directory, run it from the skill folder (the package must be importable):

cd /path/to/website-seo-audit && python3 -m seo_audit https://example.com

Useful options:

Option	Meaning
`-1`, `--single`	Audit only the given URL (no crawl)
`--max-pages N`	Max pages to crawl (default 50)
`--max-depth N`	Max crawl depth (default 3)
`--json`	Machine-readable JSON instead of Markdown
`-o FILE`	Write the report to a file
`--ignore-robots`	Crawl even if robots.txt disallows (use on sites you own)
`--no-link-check`	Skip broken-link detection (faster)

The command prints a Markdown report to stdout and exits non-zero if any critical issue was found (handy for CI).

How to interpret and report back

Run the tool on the URL the user gave. Use the default crawl unless they only want a single page (--single) or a bigger sweep (--max-pages).
Read the Markdown report. Lead with the score/grade and the issue counts.
Walk through findings in order: 🔴 critical first, then 🟡 warnings, then the highest-value 🟢 notices. For each, state the problem and its concrete fix.
Offer next steps: re-run after fixes, crawl deeper, or export JSON.

Do not dump the whole raw report unless asked — summarize the score, the critical/warning items, and what to fix first.

What it checks

On-page: title (presence/length/uniqueness), meta description, H1 & heading hierarchy, canonical, mobile viewport, html lang, image alt text, thin content, Open Graph, mixed content on HTTPS.
Technical: HTTPS, robots.txt (missing / blocks-all / sitemap directive), sitemap.xml (presence/validity), broken internal links (HTTP 4xx/5xx), duplicate titles/meta across pages, pages with no internal links.
Structured data: JSON-LD syntax validity and required Schema.org fields for Article, Product, Organization, BreadcrumbList, FAQ, Recipe, Event, and more — the signal most crawl-based tools ignore, and what AI answer engines read.

Notes

Requires Python 3.8+. No pip install needed.
Respects robots.txt by default; pass --ignore-robots on your own sites.
Stays on the same site (apex + www); external links are not followed.
