Marketing Skills v2.4.2

A content patch adding coverage of Google's Open Knowledge Format (OKF) to the ai-seo skill.

Total skills: 44 (unchanged)

Updated skill: ai-seo (2.0.1 → 2.1.0)

Adds coverage of Google's Open Knowledge Format (OKF), a v0.1 markdown spec for representing site content as an agent-readable bundle. Google introduced OKF on the Cloud blog on 2026-06-12 and ships it inside Knowledge Catalog. Suganthan Mohanadasan surfaced it for SEO/AI-search audiences.

What OKF is

A directory of cross-linked markdown files with YAML frontmatter:

• Required: type
• Recommended: title, description, resource, tags, timestamp
• Optional index.md lists the files for progressive disclosure
• The full spec fits on one page

references/okf.md (new)

New 104-line reference covering:

• What OKF is and a minimal concept-file example
• Honest framing — Google built OKF for data teams sharing catalog metadata (BigQuery tables, API endpoints, metrics, playbooks); the site-readable-by-agents repurposing popularized by Suganthan is a clever secondary use, not Google's primary framing
• What it does for AI search today — nothing immediate. Nothing crawls the web for OKF bundles yet. Treat it as protocol-layer registration — same shape of bet as early schema.org adoption was a decade ago
• Where OKF fits in the agent-readable stack — alongside sitemap.xml, robots.txt AI bot rules, llms.txt, /pricing.md, schema markup
• Three ways to ship a bundle — Suganthan's free OKF Generator (recommended for most sites), his pending WordPress plugin, or by hand
• Hosting & discovery — serve at yoursite.com/okf/index.md, add a line in llms.txt pointing to it
• When to skip — small sites, closed platforms (Wix, Squarespace) that won't allow custom paths, sites without other machine-readable files
• What to watch — v1.0 spec, AI engine adoption signals, public Knowledge Catalog ingestion endpoints

SKILL.md updates

• New OKF subsection under "Machine-Readable Files for AI Agents" pointing to the reference
• Frontmatter description extended with five new triggers: llms.txt, OKF, Open Knowledge Format, knowledge bundle, agent-readable site

references/platform-ranking-factors.md update

OKF callout added to the Google AI Overviews section, framing it as a "register early" protocol bet rather than a confirmed ranking signal.

Verification before shipping

All four primary sources confirmed live during research:

• Google Cloud blog post — live, datePublished: 2026-06-12, title "How the Open Knowledge Format can improve data sharing"
• OKF v0.1 spec — full 15KB spec retrieved from GoogleCloudPlatform/knowledge-catalog/okf/SPEC.md
• Knowledge Catalog product page — live at cloud.google.com/products/knowledge-catalog
• Suganthan's free OKF generator at suganthan.com/okf-generator/ — confirmed in his blog post
• WordPress plugin — awaiting wp.org approval at time of writing (consistent with Suganthan's own note)
