- A Claude SEO checker is a free, installable skill that makes Claude audit one layer of your site: overall score, technical health, AI visibility, trust signals, cannibalisation, and more.
- There is no single "best" checker; there is a right checker per question. The routing table below matches what you want to check to the skill that checks it.
- Every checker here is a free .md file from the Claude SEO skills library: install once, run on any site, no login and no email gate.
Searching for a Claude SEO checker usually means one thing: you want Claude to look at your site and tell you what is wrong, without paying for another tool. That is exactly what our checker skills do, and because we built all of them, this page can be specific in a way a review roundup cannot: what each one checks, what it hands back, and which one to run first. All of them are free downloads from our own library, so read this as the manual, and judge the skills by what they return on your site.
What is a Claude SEO checker?
A Claude SEO checker is a packaged skill (a structured .md instruction file) that turns Claude into an auditor for one specific layer of SEO. Instead of you writing a long prompt and hoping, the skill carries the method: what to examine, what good looks like, what to flag, and the exact report format to return. You install it once, point it at your page or site, and get back a structured check with findings and fixes rather than general advice. The full concept is covered in what are Claude SEO skills; a checker is simply a skill whose job is assessment rather than creation.
Which Claude SEO checker should you use?
Pick the checker by the question you are asking, because each one audits a different layer. This is the routing table we use ourselves:
| You want to check... | Run this checker | What it returns |
|---|---|---|
| "How does my site score overall?" | Website Score | A scored assessment against the things Google rewards in 2026, with the biggest gaps ranked. |
| Technical health (indexing, structure, speed signals) | Technical SEO Audit | A layered technical audit with findings ranked by traffic impact, each with evidence and the fix. |
| Whether AI engines can find and cite you | AI Visibility Check | An AI-search visibility assessment: crawlability for AI bots, structure, citability gaps. |
| Trust and credibility signals | Google Trust Check | A trust-signal audit (the E-E-A-T layer): what your site shows, what is missing, what to add. |
| What competitors have that you do not | Website Gap Finder | A gap analysis against a competitor site: content, structure, and coverage differences. |
| Pages competing against each other | Cannibalization Detector | Which of your pages target the same query, which should own it, and how to consolidate. |
| Whether your content would survive a quality review | Helpful Content Audit | A page-by-page check against Google's helpful-content questions, with rewrite priorities. |
| How clearly machines understand who you are | Entity SEO Auditor | An entity-layer audit: brand consistency, schema, and the signals engines use to identify you. |
| Whether AI bots actually visit your site | Clarity AI Bot Auditor | Reads your Microsoft Clarity data for AI-bot sessions: who crawls, what they read, what they skip. |
Two neighbours worth knowing about: if you run an ecommerce, B2B, SaaS, local, or restaurant site, there is a vertical audit skill tuned to your model, and if you want a full-crawl check, the Screaming Frog Analyser reads an entire crawl export. When in doubt, start with Website Score: it is the generalist that tells you which specialist to run next.
How do you run a Claude SEO checker?
Install once, then ask Claude to run the check: the whole loop takes about two minutes. Download the skill's .md file from its page (every checker above links to its own). In Claude Code, drop the folder into ~/.claude/skills/ and it loads automatically. In Claude Desktop or claude.ai, create a Project, paste the skill file into the Project's instructions, and chat there. Then run it: "check hawkacademy.co" or paste the page content you want assessed. The skill asks for whatever input it needs (a URL, an export, page copy) instead of guessing. If you have never installed one before, the skills explainer walks through both paths with screenshots.
What does a Claude SEO checker actually return?
Every checker returns a structured report: findings with evidence, ranked by impact, each with a specific fix. None of them return invented metrics. That is a deliberate design rule across the library: a checker never fabricates a search volume, a traffic number, or a score it cannot justify, and when it needs data it cannot see (your Search Console, your analytics), it asks you to paste the export rather than guessing. The honest limitation to know: a skill checks what you give it. A URL check reads that page; a site-wide verdict needs a crawl export or your GSC data. The checkers tell you which input unlocks which depth.
Are free Claude checkers better than paid SEO tools?
They do a different job: paid tools give you data, Claude checkers give you judgment. A paid platform holds databases Claude does not have: search volumes, backlink indexes, rank tracking over time. No skill replaces that. What the checkers replace is the analysis hour: reading a page the way an experienced SEO would, applying a method, and writing up what matters in priority order. For most small business owners, that judgment layer is the missing piece, and it is the part that costs the most when you buy it from an agency. Run the checkers for the diagnosis, keep a keyword tool for the numbers, and you have most of an SEO retainer's deliverables for the cost of a Claude subscription.
FAQ
What is the best Claude SEO checker?
The best Claude SEO checker depends on the layer you are checking: Website Score for an overall assessment, Technical SEO Audit for site health, AI Visibility Check for AI search presence, and Cannibalization Detector for keyword overlap. If you are starting cold, run Website Score first; its output tells you which specialist checker to run next.
Are Claude SEO checkers really free?
Yes. Every checker on this page is a free .md skill file from the Hawk Academy library: no cost, no email gate, no login. You need your own Claude account to run them, and a paid Claude plan helps for bigger checks because of usage limits, but the skills themselves are free to download and keep.
Do the checkers work in Claude Code and claude.ai?
The checkers work in both. In Claude Code they install as skill folders and load automatically; in Claude Desktop or claude.ai they run inside a Project with the skill pasted into the Project instructions. The output is the same structured report either way.
How accurate is a Claude SEO check?
A Claude SEO check is as accurate as its inputs: it reliably assesses the page content, structure, and signals you give it, and it is built never to invent metrics it cannot see. It does not have live search-volume or backlink data, so pair it with a keyword tool for numbers. Treat it like a strong junior auditor whose work you can verify, because every finding comes with its evidence.
