Changelog
A public record of when the methodology, question set, and content of this site were created and changed. Trust in measurement comes from “since when” — the dates here match the repository commit history.
Citation-unit form hardened — colophon block (first-published, last-verified, author/verifier, canonical URL) and h2/h3 anchor coordinates on every document. BreadcrumbList schema, first FAQ answer now matches the direct answer verbatim, and full JSON-LD validation became a permanent build gate. llms-full.txt and an Atom feed opened; sitemap lastmod switched to per-document measured dates. Corrected the verified-date labels of 18 wave-1 articles to match actual git history.
Second absorption wave — 17 new articles (engine deep-dives, per-type schema guides, vertical local AEO, concepts/research/global cases; all passed the web fact-check audit) + Dataset schema and CSV distribution added to the citation ledger.
Citation-rate methodology v1.0 published — 20 questions frozen, formula and judging rules public. Self-citation ledger opened under /reports (20 questions × 4 engines, all cells pending). IndexNow key deployed.
First absorption wave — 18 new articles + 6 freshness updates (passed web fact-check audit). /sources primary-source encyclopedia opened (96 official documents, all individually verified).
Deployed to Vercel production — site live at aeo.io.kr.
Initial site build — answers, guides, choose, cases, reports, tools, company; Article+FAQPage JSON-LD on every page; sitemap/robots/llms.txt.
