The researched SEO system,
in a knowledge base you own
Our free guides teach the strategy. This is the complete system behind them — 571 cross-linked notes of researched SEO knowledge bundled in Markdown (.md) and Plain Text (.txt).
Core Knowledge, Industry Playbooks, & Execution Assets
330 Cross-Linked Concepts
Keyword research, search intent, local SEO, technical SEO, content strategy, E-E-A-T, schema, link building, audits — cross-linked so you see how it fits together.
Vertical Playbooks
Healthcare · Legal · Home Services · Architecture · SaaS. What makes each vertical's SEO different — researched with sources, not opinions.
Ready-to-Use Assets
Keyword matrices, page frameworks, audit checklists, SOPs. The reusable pieces you hand to a client — or execute yourself.
Not a folder of notes — a compiled, cross-linked wiki
This is the same pattern Andrej Karpathy described as an LLM wiki: raw sources compiled into small interlinked pages, with an index that says what exists, a changelog that says what happened, and a graph that shows how it connects. It ships ready to query — no ingest pipeline to build, and no embeddings required.
Every note is catalogued and every change is logged, so an agent can find a page and know how current it is.
Notes link to the concepts they touch, so the knowledge is connected rather than stacked.
A ripgrep-powered skill for Claude Code, opencode, Pi, and Codex — plus an MCP server that lets any agent query the wiki and cite notes.

Ask your agent, get a sourced answer
The knowledge base ships as an Agent Skill, so you query it in plain language and get answers cited to the notes. Six things people use it for:
Clusters, search intent, and the order to write pages — assembled from the vault's keyword notes.
An ordered check — indexing, canonical, internal links, content decay — instead of generic advice.
E.g. "SEO for dentists," with the healthcare playbook's YMYL and E-E-A-T constraints applied.
Compare the revenue, subscription, and freemium notes; get the trade-offs traced to their sources.
Use this vault as a worked example of the Karpathy LLM-wiki pattern.
Every claim cites a note as [[Note Title]]; gaps are flagged, not filled from memory.
Full recipes, with commands and expected output, ship in USAGE.md inside the ZIP.
This site is built with the vault
You do not have to take a testimonial's word for it. The free guides on this site, the MCP server, and the Agent Skill are all produced from this knowledge base — open any of them and check. Every number on this page traces to a source.
Verify it yourself: the free guides, the MCP server, and the Agent Skill inside the ZIP.
Ten jobs you'd otherwise have to learn the hard way
Each of these is a step beginners skip — and then lose months to. The vault has already worked out the method, with the reasoning and the sources.
One intent maps to one page — not five near-duplicate posts competing with each other.
Find pages splitting the same ranking signal, then merge, redirect, or re-point them.
Cluster pages link up to the pillar, the pillar links down — nothing is orphaned.
No split signals, no duplicated titles, no SERP truncation.
Crawlability and indexation first, polish last — the order that actually moves rankings.
Extractable structure, machine-readable files, and an honest llms.txt — measured, not guessed.
No invented numbers: each figure traces to a source, so your pages survive scrutiny.
Directory submissions, alternative pages, and free tools that earn links instead of buying them.
SaaS revenue, subscription, and conversion models mapped to the pages that carry them.
A refresh system that updates, merges, rewrites, or retires pages as the market moves.
No promises. A researched system instead.
Any product that promises a specific traffic or income number is guessing or lying — search is too variable for that. What this vault does is replace guesswork with researched patterns and sourced method, so your decisions rest on evidence instead of hope.
The metrics that decide a keyword, the long tail, and why intent beats volume. Read the free guide.
The honest difficulty curve — what is learnable in weeks, what takes months of shipping.
How linked notes turn isolated research into a system that gets more useful over time.
A fit check before you buy
- You're building an SEO or content site, a SaaS, or an indie product and want the research pre-done.
- You'd rather learn and own the system than rent an agency.
- You want sources you can check, not a black box.
- You use an AI agent and want a knowledge base it can query and cite.
- You want done-for-you content, or someone else to run the work.
- You won't open the files and use them.
- You're looking for a guaranteed ranking or income promise.

Free guides teach the strategy. The knowledge base is the system.

Your knowledge base is ready.
Enter the email you paid with and we'll verify your purchase, then hand you the download. We don't store it — the ZIP is yours to keep.
What's the difference between the free guides and the knowledge base?
Free guides teach the strategy — one page per topic. The knowledge base is the compressed research behind all of them: 571 notes with keyword matrices, page frameworks, SOPs and cross-links in Markdown (.md) and Plain Text (.txt) formats. Free = learn the strategy. Paid = get the system.
How do I get it after buying?
Right after checkout you'll land on this page with a download panel. Enter the email you paid with, and you'll get an instant download of the ZIP containing both Markdown (.md) and Plain Text (.txt) versions. Open it in Obsidian, VS Code, or any text editor. No account, no subscription, no cloud lock-in — the files are yours.
Is it a one-time payment? Do I get updates?
One-time $29 — no subscription. When the knowledge base is updated, you get the new version delivered to your email automatically. Your purchase email is all we need; no account required.
Do I need special software to open the knowledge base?
No special software required. Every purchase includes both Markdown (.md) and Plain Text (.txt) formats. You can navigate the interactive visual graph using free apps like Obsidian, or read and search the notes directly with any text editor or note app.
Will this go stale?
Updates are delivered to your purchase email for free, and the vault ships with a changelog and a content-refresh method so any work built from it stays current. The index records what changed and when.
Couldn't I just build this myself?
You could — and if you have the months to spare, learning it yourself is worth it. The vault is the shortcut: the research, the concept map, and the execution assets are already compiled and cross-linked, so you start from a system instead of a blank folder.
