Analytics Events

GA4 / GTM event taxonomy for Opportunity Radar. All events fire client-side via the analytics service. Every event includes a baseline set of properties (opportunity_id, opportunity_slug, opportunity_status, country, stage, sector, source_page) — additional event-specific properties documented per event.

KPIs derived from this taxonomy

• Apply CTR = opportunity_apply_click / (opportunity_card_view + opportunity_detail_view). Target ≥4% for non-sponsored, ≥6% for sponsored.
• Card-to-detail conversion = opportunity_card_click / opportunity_card_view. Target ≥18%.
• Cross-module traversal density = opportunity_connected_signal_click / opportunity_detail_view. Target ≥0.5 (the Connected Signals rail is the platform’s defining surface for ecosystem traversal).
• Subscription conversion = opportunity_digest_subscribe / opportunity_listing_view + opportunity_subscription_submit / opportunity_detail_view. Target ≥2.5% combined.
