Best Claude SEO Tools in 2026: Skills, Checkers & Software for Claude Code

TL;DR — Claude on its own is not an SEO tool: it can write a title tag, but it cannot crawl your site, read Search Console, or change a file. A Claude SEO tool is whatever gives Claude those abilities. If you want a managed product with cloud data (Google Search Console + keyword research) and an approve-every-change workflow, install the free SEOAgent Skill for Claude Code. If you want something free and self-hosted that you can read and edit yourself, install one of the open-source SEO skills below. Both run inside Claude Code, and the open SEO skill benchmark scores what each one actually does.

Claude or Claude Code? The answer changes with the question

People search for "Claude SEO tools" meaning two different things, so it is worth separating them before picking anything.

• Claude (claude.ai, the app or the API) is a chat model. It is good at the writing half of SEO: drafting titles and meta descriptions, rewriting a thin paragraph, outlining an article, explaining a Search Console export you paste in. It cannot fetch your pages, see your rankings, or edit your site. Every "Claude SEO tool" for plain Claude is really a way to hand it data (a connector, an MCP server, or copy-paste) and then carry its output back to your site by hand.
• Claude Code is Anthropic's terminal agent. It reads and edits the files in your repo and runs commands. Give it a Skill and it becomes a checker and a fixer: it can crawl your site, find the missing canonical, write the fix into the right file, and hand you a diff. This is where almost every serious Claude SEO tool lives today, and it is what the rest of this guide covers.

If your site is a repo, use Claude Code. If your site is a CMS you edit in a browser, plain Claude plus a copy-paste loop still works — it just stays manual.

What counts as an SEO tool for a coding agent?

A few years ago "SEO tool" meant a dashboard you logged into. Now that your site lives in a repo and you're editing it through Claude Code, Cursor, or Codex, the most useful SEO tooling runs inside the agent — it reads your files, proposes changes, and writes them as commits you review.

Three categories matter here. Skills are packaged instructions (the SKILL.md format) that teach an agent how to do SEO work — audit pages, write schema, fix metadata — and most are free and open-source. Skill packs are large multi-purpose collections that bundle SEO skills alongside dozens of others. MCP servers are connectors that hand the agent live data — a Google Search Console feed, a keyword database — without telling it what to do with it. The best setups often combine a skill (the how) with an MCP server (the data). This is one corner of the broader best AI SEO tools landscape, narrowed to what runs inside a coding agent. For the setup specific to one agent, see SEO for Claude Code, SEO for Cursor, and SEO for Codex. For one job end to end, see how to automate schema markup in your codebase.

How we picked

There are dozens of SEO skills on GitHub now. We weighed four things that actually decide whether one is useful day to day:

• Does it work inside your agent? It should run in Claude Code at minimum, ideally Cursor and Codex too. Thanks to the portable SKILL.md format, most do.
• Does it ground decisions in real data? "Improve this page" is guesswork without your actual search performance. Tools that pull GSC or keyword data make better calls than tools that don't.
• Who controls publishing? The good ones propose changes and let you approve them. Be wary of anything that edits and ships without a review step.
• What's the setup cost? A free skill you clone and configure yourself trades money for time. A managed product trades the reverse. Neither is wrong — it depends on what you have more of.

We also ran every free skill we could find through seo-skill-bench, an open benchmark that executes each one against a fixture site with planted defects and scores what it found, what it fixed, and what it made up. Where a score is quoted below, that is where it comes from.

The best Claude SEO tools in 2026

1. SEOAgent — the managed SEO engine for Claude Code

SEOAgent is the only managed product on this list. It ships as a free Skill for Claude Code (the same Skill works in Cursor and Codex), plus a local seoagent CLI, and it audits your site and builds or improves SEO pages directly in your codebase — with you approving every change before it lands. The optional Autopilot cloud ($49 per site per month; check current pricing) adds the part open-source skills can't easily give you: Google Search Console analysis, competitor and keyword research via DataForSEO, and evidence-backed suggestions that come from your real performance data rather than guesses. It currently leads the SEO skill benchmark on detection and has a clean hallucination record — after finishing last in the first fleet, which we wrote up in full. Best for founders and dev teams who want the local-first, human-in-the-loop workflow of a skill but with managed cloud data behind it and zero setup. Start with the free Skill.

2. claude-seo — the most comprehensive open-source skill

claude-seo bills itself as a "universal SEO skill" for Claude Code, and the project describes a large surface — roughly 25 sub-skills and 18 sub-agents spanning technical SEO, schema, GEO/AEO, local SEO, Google API integrations, and reporting. It's a self-hosted SKILL.md setup and it's free. Best for people who want maximum coverage and are comfortable cloning, configuring, and maintaining it themselves; the trade-off versus a managed product is that you supply your own data sources and do your own upkeep.

3. Agentic-SEO-Skill — the most portable open-source skill

Agentic-SEO-Skill is an "LLM-first" SEO skill built to run across a wide range of agents — Claude, Codex, Cursor, Antigravity, Windsurf, Cline, and more. The project describes around 16 sub-skills, 10 specialist agents, and a set of utility scripts. It's free and self-hosted. Best if you switch between coding agents and want one skill that follows you across all of them, rather than betting on a single tool.

4. seo-geo-claude-skills — a popular community collection

seo-geo-claude-skills is a well-known open-source SEO and GEO (generative engine optimization) skills collection for Claude Code, maintained by the community and free to use. Best for people who specifically want the AI-answer / GEO angle baked in alongside traditional SEO, and who like working with community-maintained tooling they can extend.

5. Broad skill marketplaces — SEO bundled with everything else

Large multi-purpose skill packs like wshobson/agents, alirezarezvani/claude-skills, and kodustech/awesome-agent-skills include SEO skills among many others. They're free and open-source. Best if you're already adopting a big agent-skills library for other work and want SEO included rather than installed separately — just know the SEO depth is usually shallower than a dedicated skill's. One warning that applies to every big pack: each installed skill's description sits in Claude's context on every message, so a pack of forty skills taxes every prompt you send, fired or not.

6. MCP servers (GSC, DataForSEO) — the data layer, not a full skill

This is a complementary category rather than a head-to-head pick. A Google Search Console MCP or a DataForSEO MCP doesn't tell your agent how to do SEO — it gives any agent live SEO data to act on. Pair one with a skill above and your agent can read real search performance or keyword volumes mid-task. Best when you already know what you want done and just need to plug real data into the work. This is also the only category that works with plain Claude: connect an MCP server in the Claude app and it can read your Search Console data, even though it still cannot edit your site. (Note that SEOAgent's cloud tier already bundles GSC and DataForSEO, so you don't wire these up separately.)

Claude SEO checkers: auditing a site from inside Claude Code

A Claude SEO checker is a skill whose first job is to audit — crawl your pages, compare what it finds against a checklist, and report specific problems. This is where the differences between tools are largest, because a checker fails in a specific way: confident, specific, and wrong. "Your homepage is missing Organization schema" sounds diagnostic; if the schema is already there, the checker just invented work.

Three things separate a good Claude SEO checker from a bad one:

1. It fetches the real page. A checker that reads your source files but never requests the rendered URL misses everything the framework adds at build time — and everything a CDN strips. SEOAgent fetches the homepage, sitemap, and robots.txt, then crawls the live site and keeps the evidence next to each finding so you can verify it.
2. It reports a fix, not a score. "Meta description too short" is a number. "Meta description is 41 characters; here is the 150-character version and the file it lives in" is a task Claude Code can execute. The SEO Skill for Claude Code is built around that second shape: every finding arrives with the exact edit.
3. It knows what it did not check. The benchmark's hallucination score exists because several popular skills report problems that do not exist. Prefer a checker that says "not checked" over one that fills the gap with a guess.

If you only want the AI-answer side checked — whether ChatGPT, Perplexity, and Claude can actually read and cite your pages — the free AI-readiness checker runs in a browser with nothing to install, and it is a reasonable first pass before you set up a skill.

Claude SEO tracking tools: can Claude track rankings?

Not by itself, and not with any skill on this list. Rank and click data lives in Google Search Console (or a paid rank tracker), and a skill is instructions, not a database. So a Claude SEO tracking tool is really one of three setups:

• A Search Console MCP server. Connect one and Claude Code (or plain Claude) can query impressions, clicks, and average position for any page or query on demand. This is the cheapest option and the best fit if you already know which pages you want to watch.
• SEOAgent's cloud tier. It syncs Search Console into the workspace, then turns the numbers into tasks — a page with impressions but no clicks, a query that slipped off page one, an orphan page — and hands each one to Claude Code as a change to review. That is tracking that ends in a diff rather than a chart.
• A rank tracker export. Ahrefs, Semrush, and the like can export positions as CSV; paste or pipe that into Claude and it will summarize the movement. It works, but nothing about it is automatic.

Whatever you choose, be suspicious of any skill that claims to "track rankings" on its own. Unless it names the data source, it is estimating.

How to choose

It comes down to what you value more: managed convenience or free flexibility.

• You want a managed product with real data and an approval step → SEOAgent. If you'd rather not assemble and maintain your own stack, and you want suggestions grounded in your actual GSC and keyword data, the free Skill for Claude Code plus the optional cloud tier is the most direct path. It's also the right fit if you're a builder shipping SEO for developers work straight from your repo.
• You want free and hackable → an open-source skill. claude-seo, Agentic-SEO-Skill, or seo-geo-claude-skills give you the full SEO playbook as files you can read, fork, and bend to your workflow. You supply the data and the upkeep, but you pay nothing and control everything.
• You already have a data need → add an MCP server. If your agent is fine on the how but blind to your real performance, bolt on a GSC or DataForSEO MCP and keep your existing skill.
• You are on plain Claude, not Claude Code → MCP plus copy-paste. Connect a Search Console MCP for the data, use Claude for the writing, and carry the changes to your site yourself. When that loop gets tiring, that is the moment to move the site into a repo and install a skill.

Frequently asked questions

What is the best Claude SEO tool?

For anyone with a codebase, a Skill for Claude Code beats a separate SEO app, because it works where the site actually lives. SEOAgent's free Skill is the strongest pick for a managed, zero-setup experience with cloud data and an approve-every-change workflow, and it currently leads the open SEO skill benchmark. For a free, self-hosted option you fully control, claude-seo is the most comprehensive open-source skill, with Agentic-SEO-Skill close behind if you need cross-agent portability.

Is there a Claude SEO checker?

Yes — any of the skills above will audit a site from inside Claude Code, and the quality gap between them is mostly in how they check. SEOAgent crawls the live pages and attaches evidence to every finding; the open-source skills vary, and the benchmark's hallucination score shows which ones report problems that are not there. For an install-free check of whether AI answer engines can read your site, use the AI-readiness checker.

Can Claude track SEO rankings?

Not on its own. Claude has no ranking data unless you give it some: a Google Search Console MCP server, SEOAgent's cloud tier (which syncs GSC and turns it into tasks for Claude Code), or a CSV export from a rank tracker. Treat any skill that claims to track rankings by itself as an estimate until it names its data source.

Can I do SEO with Claude without Claude Code?

Partly. Plain Claude is good at the writing half — titles, meta descriptions, outlines, rewriting thin sections — and with a Search Console MCP connected it can read your performance data too. It cannot crawl your site or edit files, so every change still travels back to your site by hand. Claude Code plus a skill closes that loop: it finds the problem, writes the fix into the right file, and shows you the diff.

Are these SEO tools free?

The open-source skills — claude-seo, Agentic-SEO-Skill, seo-geo-claude-skills, and the broader skill marketplaces — are all free and self-hosted. SEOAgent's Skill and CLI are free too; only the optional cloud tier (Search Console analysis plus competitor and keyword research) costs $49 per site per month. Check current pricing before you commit.

Do they work in Codex and Cursor, or just Claude Code?

Many work across all three. Because Claude Code, Codex CLI, Cursor, Gemini CLI, Copilot, and Cline now support the SKILL.md format, skills are portable between agents. SEOAgent and Agentic-SEO-Skill explicitly target Claude Code, Cursor, and Codex; some skills are Claude-Code-first, so check each project's supported agents.

Skill vs MCP — what's the difference?

A skill teaches your agent how to do something — the steps, the checklist, the SEO playbook. An MCP server gives your agent data or access — a live Google Search Console feed, a keyword database — without prescribing what to do with it. They're complementary: a skill decides the work, an MCP supplies the facts. The best setups use both.

Can these tools publish changes for me automatically?

The good ones don't. SEOAgent is deliberately local-first and human-in-the-loop — it proposes changes as commits and waits for your approval. Open-source skills behave the way you configure them, but the safe pattern is always a review step before anything ships. Treat "edits and publishes on its own" as a reason to look closer, not a selling point.

Conclusion

If your site lives in a repo, the best Claude SEO tool is the one that runs where you already work — inside Claude Code, Cursor, or Codex. Pick by what you have more of: short on time, want managed cloud data and an approval step, install the SEOAgent Skill for Claude Code and try the free tier on a real page today. Short on budget and happy to self-host, clone claude-seo or Agentic-SEO-Skill and start auditing. Before you pick, check the live SEO skill benchmark — an open leaderboard that runs every free skill against a fixture site with planted defects and scores what each one actually did (how we built it). For the wider category, see what an SEO agent is. Either way, keep yourself in the loop and approve every change.
