The Claude Code SEO agent stack is what turns a 25-hour manual process into a 30-minute automated one, and after running it daily I've got every tool, API, and integration nailed down to where I can hand it over.
People ask me what the stack actually is, so here's every tool, API, and integration in my Claude Code SEO agent setup. If you want to copy this, the stack is the foundation.
The Top-Level Stack
Six core pieces form the stack. Claude Code is the agent itself. A custom skill is the workflow recipe. Eleventy (11ty) is the static site generator. Netlify handles hosting and deploys. Omega Indexer handles fast Google indexing. Google Sheets handles tracking.
Each piece does one job and each is replaceable if you prefer alternatives.
The Agent: Claude Code
I use Claude Code Desktop. Why Desktop specifically? Pinned conversations for ongoing workflows, quick access to multiple skill chats, and better file system integration than browser-based tools.
If you've used Free Claude Code or Claude Code Local, this is the same baseline.
The Skill: My Custom SEO Workflow
The skill is a markdown file in ~/.claude/skills/ and it's structured around five sections. The name and description tells Claude when to invoke it. Step-by-step instructions for each phase covers research, write, deploy, index, and track. Site folder paths cover all my sites. Deploy commands are specified per site. API templates handle Omega Indexer and Google Sheets calls.
When I trigger the skill with a keyword, Claude Code follows the markdown end to end. The whole orchestration lives in one file.
The Site Generator: Eleventy
I run all 5 sites on Eleventy because it's markdown-first which is perfect for AI-generated content, the builds are fast, the deploys are simple, and there's no JavaScript bloat.
Each site has the same structure with different branding. The agent saves markdown files, runs the build, and deploys.
Hosting: Netlify
All 5 sites are on Netlify because the free tier covers a lot, the API supports automated deploys, form handling and serverless functions are available if needed, and domain management is built in.
The agent calls the Netlify CLI directly with netlify deploy --prod --dir=_site, which deploys the latest build.
Indexing: Omega Indexer
This is the secret weapon of the stack. Without it, content takes weeks to get indexed by Google. With it, indexing happens in hours.
The agent submits URLs to the Omega Indexer API after each deploy. It costs 1 credit per URL, so for 5-site deploys that's 5 credits per keyword.
I cover indexing tactics in How To Rank In Google AI Mode — Omega Indexer is what makes the timing work.
Tracking: Google Sheets
The simplest possible tracker has eight columns: keyword, video URL, status (DONE), and one column per site URL across the five sites.
The agent updates the sheet via Chrome MCP browser automation after publishing. I can scan the sheet to see what's been published in 10 seconds.

Optional Tools In The Stack
These are nice-to-haves but not essential. Chrome MCP handles sheet automation and Omega Indexer UI fallbacks. Tavly handles deeper web search inside Claude Code. Notion handles the keyword backlog if you don't want a sheet.
Why I Don't Use Other Tools
I'll be straight about what I avoid and why.
AI writing platforms like Jasper or Copy.ai are too generic. The output reads like AI and the quality is below my bar.
Manual WordPress is slower than Eleventy with plugin overhead and isn't as friendly to AI deploys.
Generic SEO platforms add a layer of cost when the agent already is the platform. Adding another layer just adds cost without value.
How The Stack Components Talk To Each Other
Here's the whole flow, end to end. Claude Code reads the keyword. Skill instructions tell it where to save the markdown. Markdown saves to the Eleventy posts folder. The skill runs npx @11ty/eleventy to build. The skill runs netlify deploy --prod --dir=_site to deploy. The skill calls the Omega Indexer API to submit the URL. The skill calls Chrome MCP to update the Google Sheet.
Each step is one function call from the skill. The agent orchestrates the lot.
Stack Variations You Could Use
The same workflow with different tools. Hugo instead of Eleventy. Vercel instead of Netlify. Indexnow instead of Omega Indexer. Notion instead of Sheets. OpenClaw instead of Claude Code (see OpenClaw AI SEO).
The pattern is what matters. The exact tools are personal preference.
Total Cost Of The Stack
Honest breakdown. Claude Code subscription runs roughly $20/month. Netlify hosting is free tier or paid if you scale. Eleventy is free. Omega Indexer credits depend on volume. Google Sheets is free.
For someone publishing 1 keyword/day across 5 sites, monthly cost lands around $50-$100. Compared to a $5K/month SEO agency, that's a steal.
What's Hard About This Stack
Three honest difficulties to plan for.
The skill takes time to dial in. My first version was rough and it took 3-4 iterations to get the article quality right.
Site setup once is real work. You need 5 working Eleventy sites on Netlify before this workflow runs, which is a few hours of upfront work.
API key management requires care. You need API keys for Netlify, Omega Indexer, and optionally Google Sheets. Store them safely.
What's Easy About This Stack
Adding a new keyword takes 30 seconds. Each article comes out at professional quality. Indexing is fast. Tracking is automatic.
The hard work is setup. The easy part is running it.
Daily Reality
What a normal day actually looks like. At 8:00 I pick a keyword from my backlog sheet. At 8:01 I trigger the Claude Code SEO agent. By 8:25 five sites are deployed, indexed, and the sheet is updated. At 8:26 I move on with my day.
That's it. The stack runs and I drink coffee.
