Changelog

Lifetime updates is a purchase promise. This page is where it is kept in public, so a buyer can see the difference between a product that is maintained and one that is not.

1. v2.1.02026-09-11

   One simpler offer: your coding agent sets up your technical SEO, for $49.

   • •The agent skill drops from $99 to $49, one time. Buyers at $99 keep lifetime updates and are not charged again
   • •The site now describes the skill by what it does: plug it into your AI code editor, it audits the site, then sets up what is missing in your project
   • •Implementation code no longer appears on the checklist. Every check still carries why it matters and a command to verify it, and the skill still ships everything your agent needs to set each one up
   • •Both exits are published with their escrow records: Foreclosure Data Hub sold for $28,000 and USAgentLeads for $12,000
   • •Both products' Search Console performance is published as a receipt, labelled with its domain
2. v2.0.02026-08-27

   The playbook becomes an agent skill, and the two products behind it are named.

   • •The agent skill is now the only paid product. It ships the workflow, two slash commands, all 112 checks as an agent-readable reference, the scoring methodology, the TypeScript reference implementations and two case study teardowns
   • •OpenCode joins Claude Code, Cursor and Codex as a supported host, each with a one-step install
   • •New /seo-audit and /seo-implement commands: the audit reports and changes nothing, the implement command works the approved plan one check at a time
   • •All 20 playbook chapters are now free to read. The reader and its entitlement are retired, and /library/reader redirects to the public chapter
   • •The Code Kit is no longer sold separately. Its 19 modules ship inside the skill as the reference implementations the agent reads, and /code-kit redirects to /skill
   • •New /results case studies naming foreclosuredatahub.com and usagentleads.com, the two products this playbook was run on and which were sold
   • •Wrote the two kit modules that eight checks referenced but which had never shipped, so every check claiming an implementation now has one
   • •Corrected the snippet counts sitewide: the free tier shows 18 of 76 implementation snippets, not 26 of 112. Both figures are now derived from the registry
   • •Pricing collapses from three tiers to one paid product
3. v1.1.02026-07-31

   The site auditor.

   • •Site auditor: enter a URL, get it scored against 39 checks from the playbook checklist with evidence and a fix per check
   • •The seventh free tool, and the second that fetches a URL server-side; the same SSRF constraints as the schema validator apply
4. v1.0.02026-07-27

   First release.

   • •20 playbook chapters covering foundation through failure modes
   • •112 implementation checks across 12 groups, each with a runnable verification
   • •The Code Kit: 17 tested TypeScript modules
   • •43 schema type reference pages, 82 glossary terms, 8 framework pages
   • •Six free tools including the llms.txt generator
   • •Public self-audit at /proof, including the checks this site fails

Buyers are emailed when the version increments. Two chapters are reviewed quarterly because they age fastest: bot economics and AI answer engines. Everything else is annual, and the methodology page states the cadence.
