PostHog SEO/GEO tracking

Build a defensible measurement path from anonymous acquisition to business outcome. The core contract is:

anonymous landing -> immutable first touch -> signup -> identify -> trusted billing event -> dashboard

Use one PostHog project across the marketing site and app when the product journey crosses both surfaces. Preserve the user's existing framework, consent model, auth, billing, and analytics conventions.

Scope and boundaries

• This skill owns PostHog instrumentation, first-party acquisition attribution, conversion/revenue events, validation, and the SEO/GEO dashboard.
• geo-audit-report measures whether a brand appears in AI answers, citations, maps, and search traces. It is complementary, not a substitute for this skill.
• PostHog can observe organic-search and LLM-referral visits; it cannot recover the Google query behind an organic visit. Use a connected Search Console source for verified branded/unbranded query reporting, or label a landing-page rule as an “unbranded SEO proxy.”
• First-touch attribution is a consistent reporting model, not proof of causality. LLM referrals undercount influence that later becomes direct or branded search.
