What is an SEO agent system with Claude Code?

It's a set of 12 specialized Claude Code skills that automate the entire SEO, GEO and AEO process: from keyword research to optimized content generation and results monitoring. Each skill is an agent that executes a specific task in the workflow.

What is GEO and AEO and why do they matter?

GEO (Generative Engine Optimization) optimizes content to be cited by LLMs like ChatGPT and Gemini. AEO (Answer Engine Optimization) optimizes for featured snippets and direct answers. Both complement traditional SEO and are key because more and more people are searching for information in AI instead of Google.

How much does it cost to replicate this system for my business?

The system was designed to work without paid API costs. You only need Claude Code and access to Google Search Console (free). When volume justifies it, paid APIs can be activated for approximately USD 75/month for full automation.

What real results did Duotach get with this system?

Duotach was already ranking in ChatGPT and Gemini for automation keywords before this system. With the Claude Code focus, we identified a total gap in the Argentine market: no company was positioning for Claude Code services. The first pages generated by the system are already indexed.

Case Study

SEO/GEO/AEO System with Claude Code Agents

SEO + LLM Optimization

3 days of development

duotach.com

Duotach is a software and AI automation consultancy based in Buenos Aires, Argentina. Specialized in WhatsApp chatbots, N8N automation and custom software development. Duotach uses Claude Code as its primary development tool and already ranks in LLMs like ChatGPT and Gemini for automation keywords.

The goal was to create an internal system to offer SEO, GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization) services in a standardized way for multiple clients, using Claude Code agents and skills to automate most of the process.

The Challenge

Running SEO, GEO and AEO services for multiple clients manually was too time-consuming
Each client required keyword research, technical audits, content generation and monitoring — all from scratch
Traditional SEO agencies charge USD 1,500+/month and deliver monthly reports with days of latency
There was no standardized workflow that guaranteed the same quality of service for all clients
LLM optimization (GEO/AEO) is a new field with no established tools or methodologies

The Solution

12 Specialized Claude Code Skills

We created reusable skills for each step of the process: onboarding, keyword research, SERP analysis, technical audit, schema generator, content briefs, content writer, GEO optimizer, GBP strategy, GSC reports, competitor intel and Next.js converter.

Multi-Agent Architecture

A main agent orchestrates the complete workflow per client. Specialized subagents execute tasks in parallel: one researches keywords while another audits the site technically and another analyzes the competition.

Templates and Schemas Based on Duotach

We extracted the patterns that worked on duotach.com (10+ types of schema markup, blog structure, service pages) and converted them into reusable templates for any client.

Client Folder System

Each client has their own folder with config.json, brand voice, research, audits, generated content, schemas and reports. All organized and versioned.

Free Approach + Upgrade Path

The system works without paid APIs using Claude WebSearch + free tools (GSC, Google Trends). Includes ready-to-activate scripts for paid APIs (Keywords Everywhere, Serper, DataForSEO) when client volume justifies it.

The most valuable thing about this system isn't the automation itself — it's that it democratizes professional SEO. Before, doing SEO, GEO and AEO well required a USD 1,500/month agency or years of experience. With Claude Code agents, we standardized the process into 12 skills that any project can use. The first test was with Duotach: we discovered that nobody in Argentina offered Claude Code services. The pages generated by the system are already indexed.
