Three layers.
1. Business outcomes. Cost per qualified lead or sale, brand-search lift on Google plus Reddit (typically rises 8-20 percent during active Reddit campaigns), HubSpot pipeline contribution for B2B (the HubSpot integration in April 2026 closed the CRM loop), Shopify revenue contribution for e-commerce (Shopify integration March 2026).
2. Attribution caveats. The Reddit-detour distortion (Search Engine Land, 15 April 2026) means last-click systematically under-credits Reddit on cross-channel measurement (the magnitude is account-specific and surfaces during a marketing-mix-modelling refresh). Marketing Mix Modelling with a Reddit line item is non-optional above $50,000 per quarter.
3. The bets. Which subreddits delivered (with the brand-safety exclusion list working), what Conversation Ads performed in high-intent threads, which AMA Ads (launched January 2025) earned brand-led discussion moments, where Reddit Search Ads (in beta through 2025; US-first, broader rollout in flight) captured search-intent before Google paid would have.
