If you're building or operating a chatbot, understanding monetization metrics is crucial to maximizing your revenue potential. Unlike traditional web advertising, conversational monetization has its own set of KPIs that reflect the unique nature of chat-based interactions.
In this guide, we'll break down the four essential metrics every chatbot publisher should know: eRPM, EPC, CTR, and CVR.
eRPM (Effective Revenue Per Mille) measures how much revenue you earn per 1,000 sessions or conversations. It's the gold standard for comparing monetization performance across different traffic sources and time periods.
eRPM = (Total Revenue / Total Sessions) × 1,000
If you earned $50 from 10,000 conversations:
eRPM normalizes your revenue regardless of traffic volume, making it easy to:
| Traffic Quality | eRPM Range |
|---|---|
| High-intent (shopping, finance) | $8 - $25 |
| Medium-intent (travel, education) | $4 - $10 |
| Low-intent (general chat) | $1 - $5 |
EPC (Earnings Per Click) tells you how much you earn each time a user clicks on a sponsored recommendation. It's particularly important for affiliate-based monetization.
EPC = Total Revenue / Total Clicks
If you earned $100 from 500 clicks:
EPC helps you understand:
CTR (Click-Through Rate) measures the percentage of users who click on a sponsored recommendation after seeing it. It's a key indicator of relevance and user engagement.
CTR = (Clicks / Impressions) × 100
If 200 users clicked out of 5,000 who saw an offer:
CTR reflects:
| Ad Type | Typical CTR |
|---|---|
| Native in-chat recommendations | 3% - 8% |
| Banner-style interruptions | 0.5% - 1.5% |
| Sidebar/peripheral ads | 0.1% - 0.5% |
Pro tip: Native, contextual recommendations in chat can achieve 3-5x higher CTR than traditional display ads because they feel like helpful suggestions, not interruptions.
CVR (Conversion Rate) measures the percentage of clicks that result in a completed action - typically a purchase, signup, or booking.
CVR = (Conversions / Clicks) × 100
If 20 purchases came from 500 clicks:
CVR tells you:
These four metrics work together to paint a complete picture of your monetization health:
eRPM = Sessions × (Impressions/Session) × CTR × CVR × Average Commission
