Claude SEO is a free, AI-powered SEO analysis skill that installs directly into Claude Code. It runs full site auditsm generates SEO strategies, optimizes images for search, and even performs generative engine optimization (GEO) analysis for AI Search.

For developers and SaaS builders managing their own websites, this tool consolidates several expensive SEO services into a single workflow.

What Claude SEO Actually Does

Claude SEO is an open-source skill available on GitHub that extends Claude Code with a suite of SEO-focused commands. Once installed, it can analyze your website’s technical health. It generates strategic plans. It audits images. Finally, it evaluates your site’s readiness for AI-driven search results.

The skill works by deploying sub-agents that crawl your site in parallel. These agents read your robots.txt file, analyze your sitemap, and evaluate page structure. They check canonical URLs, flag 404 errors, and review schema markup. This process essentially performs the same checklist a professional SEO consultant would work through during a technical audit.

Installation: One Command, Full Setup

Setting up Claude SEO requires a single curl command. Running it downloads the skill files, installs the sub-agents, and handles all Python dependencies. The entire installation completes in seconds.

Once installed, you access Claude SEO commands by typing `/` followed by the specific function you want to run. All available skills appear in a list, and each one maps to a documented command on the project’s GitHub page.

No additional configuration is necessary. You only need to have Claude Code operational in your environment. This could be a standalone terminal, VS Code, or Cursor.

Running a Full SEO Site Audit

The `/seo audit` command accepts a URL and launches a comprehensive technical review. During testing on a live SaaS website, the audit process worked through the following steps:

– Homepage detection: Identified business type and primary content structure

– Robots.txt analysis: Verified crawler access rules

– Sitemap evaluation: Checked for low-value pages and missing entries

– Canonical URL review: Found subpages with canonicals incorrectly pointing to the homepage

– 404 error detection: Flagged placeholder blog and guide pages returning errors

– Title tag analysis: Identified duplication across pages

– Schema validation: Reviewed structured data implementation

The audit produced a detailed markdown report with a prioritized list of critical fixes. From there, Claude SEO can apply those fixes directly to your codebase. They can edit layout files and correct canonical tags. They also remove broken sitemap entries and update title tags. Everything is done with your approval at each step.

Strategic SEO Planning for SaaS

The `/seo plan` command generates a targeted SEO strategy based on your business type. When configured for a SaaS platform, it produced a comprehensive strategic document. This document included indexed page counts. It also provided content gap analysis and prioritized action items.

This function draws from the audit data already collected. Running it after a full site audit gives the most complete output. The resulting plan identified 14 indexed pages. It also identified six blog posts and six guide posts. There are specific recommendations for content development and technical improvements [internal link: SaaS SEO strategy guide].

GEO: Preparing for AI Search Results

Generative engine optimization is a distinct focus area within Claude SEO. The GEO analysis evaluates how well your site is structured for AI-powered search engines. These engines synthesize answers instead of returning traditional link lists.

Key checks include:

– AI crawler access through robots.txt directives

– LLMs.txt file presence and formatting — a dedicated file that helps AI systems understand your site’s purpose and structure

– Content citability — whether your page content is structured in a way that AI models can reference directly

– Server-side rendering verification for content accessibility

The tool generates a GEO analysis report in markdown format. It provides you with a clear roadmap for improving visibility in AI search results.
