Claude SEO alternatives (2026), by reason for leaving
By Adrien Pennetier, PENRA · updated
Stay on Claude SEO if it runs well for you, because it is free. Look elsewhere if you have no Claude Code, an older Python, or a need for live volumes. Anthropic's free plugin is the first thing to try. We make one of the options below, so this page is not an independent review.
This page is about Claude SEO, the open-source skill by AgriciDaniel, not about using Claude for SEO in general. We make SEO Skills by PENRA, listed last. Facts read on each vendor's page or repository on 1 November 2026.
Which alternative fits your reason for leaving?
| Your reason | Look at | What the vendor states | The catch |
|---|---|---|---|
| A full audit uses too much of your plan | Stay, and use a single-page check | Its readme says a full audit uses more of your plan than a single-page check | You audit page by page |
| You don't use Claude Code | Anthropic's plugin, SE Ranking SEO Skills | Plugin: primarily designed for Cowork. SE Ranking: Claude Desktop (Cowork) recommended | SE Ranking needs API access |
| Your Python is older than 3.11 | GEO-SEO Claude, Aaron Marketing Skills | GEO-SEO: Python 3.10+. Aaron: no pip step, small Bash and Python-stdlib scripts | GEO-SEO still lists the Claude Code CLI |
| AI answers matter more than Google | GEO-SEO Claude | "GEO-first SEO skill for Claude Code" | Its readme also promotes a Skool community |
| You need search volumes or backlinks | SE Ranking SEO Skills, OpenSEO | Both read a paid data source | Usage or subscription cost |
| You want SEO next to copy and CRO | Marketing Skills, Aaron Marketing Skills | Broad marketing libraries | SEO is one part of each |
| You use Codex or Cursor as well | Marketing Skills, Aaron Marketing Skills | Both list several agents | Check your agent's skill support |
What should you try before leaving?
Anthropic's marketing plugin is free under Apache 2.0, and its /seo-audit command covers keyword research, on-page analysis, content gaps and technical checks. Without a connected tool it uses web search. It is the baseline: if it answers your question, you need nothing else.
How do the alternatives compare?

What does each option do, and what is the catch?
Aaron Marketing Skills. 120 marketing skills across 7 disciplines, 16 for SEO and GEO. It says every skill runs at its first tier "with data you provide", and connectors are optional. The catch: SEO is a slice of a large library.
ClaudeFast Growth Kit. A paid kit for sales, marketing and research, with a Complete Kit at $149, down from $198. The catch: we did not see the files, and its home page shows no refund wording in the text we read.
GEO-SEO Claude. 13 sub-skills centred on AI search. The catch: it lists the Claude Code CLI, and its readme promotes a Skool community. The tool itself is free.
Marketing Skills. A library for Claude Code, Codex, Cursor, Windsurf and other agents that support the Agent Skills spec. Its readme says Verified Partners fund the work, and the project lists them. The catch: SEO is one category among many.
OpenSEO. An open-source SEO platform that connects to agents over MCP. It covers keyword research, backlinks, rank tracking, audits and AI-search visibility. Plans: Base $10/month, Pro $30/month, Agency $200/month. The free trial includes $0.50 of credits. The catch: each action has a data cost plus 28%, and you need an active subscription even with top-up credits. We could not confirm its licence on the pages we read.
SE Ranking SEO Skills. 26 skills on SE Ranking's data, under MIT. It installs in Claude Desktop, Claude Code or Cursor. The catch: "API access is required", and its last release dates from June.

Where do the sources disagree?
| Topic | One source says | Another says | What you can do |
|---|---|---|---|
| SE Ranking pay-as-you-go | "$50 minimum deposit" | The same page shows from €45.00 for 250K credits | Confirm at checkout |
| GEO-SEO Claude stars | ClaudeFast's SEO page: 4.8k | GitHub API on 1 November 2026: 11,398 | Read the repository |
| Marketing Skills size | Our guide on 15 October 2026: 50 skills | Readme table on 1 November 2026: 53 skills | Recount before citing |
Who should pick none of these?
If you have one site and Search Console, ask Claude a precise question with your export first. If you already pay for Ahrefs or Semrush, connect it rather than adding another layer.
How was this list built?
Rule: a pack, plugin or connector that works in Claude, names SEO in its own description, and has a public page readable on 1 November 2026. Left out: single-purpose skills, skill catalogues and general SEO suites. Order: baseline first, then alphabetical, our product last.
We read vendor pages and GitHub records and did not test audit quality. No figure here is a forecast. Found an error? Write to penra.contact@gmail.com. Vendors can ask for a correction or reply. Changelog: 1 November 2026, first version.
