An SEO audit tool for checking a web page or site URL. SEO means improving how pages appear in search engines; E-E-A-T covers the experience, expertise, authority, and trust shown by content, while Schema.org data gives search engines structured information.

For auditing a URL, reviewing technical SEO and content quality, checking Schema.org markup, and producing JSON or Markdown reports with suggested fixes.

It turns technical, content, and structured-data checks into a score, grade, and ordered list of problems. This helps separate urgent search-related issues from lower-priority improvements.

seo-audit — Skill for Claude Code by FreeAutomation-Tech

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add FreeAutomation-Tech/claude-seo-kit --skill seo-audit

Clone the repo

git clone --depth 1 https://github.com/FreeAutomation-Tech/claude-seo-kit

Made for: Claude Code.

Or install claude-seo-kit, the plugin that ships this one along with the rest of its 7 skills, 1 MCP server.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00071	$0.00620
Opus 5	$0.00036	$0.00310
Sonnet 5	$0.00014	$0.00124
Haiku 4.5	$0.00007	$0.00062

Security

Grade A, and why

seo-audit scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

SEO Audit

Audit any URL for technical SEO, content quality & E-E-A-T, and structured data. Produces a 0-100 score, an A-F grade, and prioritized recommendations (error → warning → info) you can hand straight to the user.

Prerequisites

pip install -r requirements.txt

(Or, if the repo is installed as a package: pip install -e .)

Procedure

Run the audit for the target URL:
```
python -m seo_kit.cli "<url>" --format json
```
Use --format markdown for a human-readable report, or --output report.md to save to a file.
Read the output. overall_score is the grade; categories holds technical, content, and schema scores; recommendations is the prioritized fix list.
Summarize for the user, ranked highest-severity first:
- What the page does well (any pass findings / high sub-scores).
- What is broken (errors) and what needs attention (warnings).
- The concrete fix for each item.
Offer to apply fixes. Many fixes are in-page edits:
- Missing/weak title or meta description → write a new one.
- Missing H1 → propose one.
- Images without alt → generate alt text from context.
- No structured data → use the seo-schema skill.
Re-run the audit after changes to confirm the score improved.

Notes

If the URL fails to load, the tool returns an error — report it and ask for a corrected URL.
For deeper checks (sitemap, hreflang, GEO) use the sibling skills: seo-technical, seo-content, seo-schema, seo-sitemap, seo-hreflang, seo-geo.
This skill is an original implementation inspired by AgriciDaniel/claude-seo (MIT) and seranking/seo-skills (MIT).

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

scrape-batch

Extract many known URLs in one polite, rate-limited pass. Use when the user hands over a list of links, a set of search hits to read in full, or asks to "scrape these pages" / "pull the content from all of them". Drives extract(action="batch"), which fans out with per-domain rate limiting and returns partial results…

research-topic

Multi-step research orchestration. Use when user asks "research X", "summarize current state of Y", "what's the latest on Z", or compares approaches. Calls extract(action="agent") which searches the web, extracts top results, then synthesises a citation-preserving Markdown answer with one configured LLM.

temporal-query

Answer time-travel questions over stored memory — what was believed at a past point in time, when a belief changed, and what replaced it. Use when the user says "as of", "back in", "at the time", "history of", "timeline", "what did I think then", or asks why a current memory contradicts an older one.

memory-commit

Use when the user explicitly says "remember this", "save this", "ghi nho", "luu lai", "save for next time", or otherwise asks to persist the immediately preceding context. Captures with the appropriate contexttype (decision, preference, fact, skill, task, conversation) so future sessions can retrieve it accurately.
