An SEO workflow for improving how websites appear in search engines. SEO covers technical items such as crawl access and structured data, as well as page content and keyword planning.

Auditing robots.txt, canonicals, redirects, headings, metadata, sitemaps, structured data, Core Web Vitals, and internal links.

It helps find issues that can stop important pages from being indexed or make their purpose unclear to search engines.

seo — Skill for Claude Code and Codex by majiang213

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 majiang213/OpenClaw-MAS --skill seo

Clone the repo

git clone --depth 1 https://github.com/majiang213/OpenClaw-MAS

Made for: Claude Code, Codex.

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	$0.00054	$0.00952
Opus 5	$0.00027	$0.00476
Sonnet 5	$0.00011	$0.00190
Haiku 4.5	$0.00005	$0.00095

Security

Grade A, and why

seo 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 6d 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.

The opening of the file, as written. The whole thing — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.

SEO

Improve search visibility through technical correctness, performance, and content relevance, not gimmicks.

When to Use

Use this skill when:

auditing crawlability, indexability, canonicals, or redirects
improving title tags, meta descriptions, and heading structure
adding or validating structured data
improving Core Web Vitals
doing keyword research and mapping keywords to URLs
planning internal linking or sitemap / robots changes

How It Works

Principles

Fix technical blockers before content optimization.
One page should have one clear primary search intent.
Prefer long-term quality signals over manipulative patterns.
Mobile-first assumptions matter because indexing is mobile-first.
Recommendations should be page-specific and implementable.

Technical SEO checklist

Crawlability

robots.txt should allow important pages and block low-value surfaces
no important page should be unintentionally noindex
important pages should be reachable within a shallow click depth
avoid redirect chains longer than two hops
canonical tags should be self-consistent and non-looping

Indexability

preferred URL format should be consistent
multilingual pages need correct hreflang if used
sitemaps should reflect the intended public surface
no duplicate URLs should compete without canonical control

Performance

LCP < 2.5s
INP < 200ms
CLS < 0.1
common fixes: preload hero assets, reduce render-blocking work, reserve layout space, trim heavy JS

Structured data

homepage: organization or business schema where appropriate
editorial pages: Article / BlogPosting
product pages: Product and Offer
interior pages: BreadcrumbList
Q&A sections: FAQPage only when the content truly matches

On-page rules

Title tags

aim for roughly 50-60 characters
put the primary keyword or concept near the front
make the title legible to humans, not stuffed for bots

Meta descriptions

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.
