What it does
SEO Audit is an agent skill from kostja94/marketing-skills. When the user wants to run an SEO audit, technical SEO audit, or site health check. Also use when the user mentions "SEO audit," "technical audit," "site audit," "crawl audit," "indexing audit," "SEO health," or "fix SEO issues." For prioritization and organic strategy, use seo-strategy. For GSC data analysis, use google-search-console.
Its SKILL.md is about 990 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Marketing & SEO, covering SEO audit and Technical SEO. It works with Google Search Console. The repository describes itself as: Agent Skills for Marketing — SEO, Social, Influencer & More. 160+ open-source skills for SEO, content, 40+ page types, paid ads, channels, and strategies. Add project context… The licence is MIT.
When your agent uses it
- Wants to run an SEO audit
- Technical SEO audit
- Site health check
- The user mentions SEO audit
Example prompts
- “SEO audit,”
- “technical audit,”
- “site audit,”
- “/seo-audit”
What it can do on your machine
Read from SKILL.md and the folder at commit 8dd89c5. 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
SEO Audit loads about 988 tokens when it runs. Until then it costs about 87 tokens; SKILL.md has 371 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.

Strategies: SEO Audit
Guides end-to-end SEO audit: technical foundation, on-page, content, and off-page. Execute in order—technical blockers prevent indexing; on-page limits rankings; content and off-page build authority. Use when auditing an existing site or planning fixes.
When invoking: On first use, if helpful, open with 1–2 sentences on what this skill covers and why it matters, then provide the main output. On subsequent use or when the user asks to skip, go directly to the main output.
Audit Order
| Phase | Focus | Skills |
|---|---|---|
| 1. Technical | Crawl, index, sitemap | robots-txt, xml-sitemap, canonical-tag, indexing, site-crawlability |
| 2. On-Page | Metadata, structure, schema | title-tag, meta-description, page-metadata, schema-markup, internal-links, heading-structure |
| 3. Content | Gaps, intent, optimization | keyword-research, content-strategy, content-optimization |
| 4. Off-Page | Backlinks, authority | link-building, backlink-analysis |
Principle: Fix foundation before optimizing pages. See seo-strategy for workflow and prioritization.
