8 Metrics. Every Referral Follow-Up Question Covered.
NPS (Net Promoter Score)
a single question trying to capture how someone truly feels about you.
Viral Coefficient (K-factor)
the number that decides whether your users are quietly doing your marketing for you.
Referral Rate
how much of your growth is coming from a program you actually built, versus general word of mouth.
CSAT (Customer Satisfaction Score)
a quick pulse check, taken right after a specific moment that matters.
Word-of-Mouth Coefficient
growth that happens without you ever building a referral button.
Share Rate
the gap between "I like this" and actually telling someone about it.
Invite Acceptance Rate
sending an invite is easy — getting someone to act on it is the real test.
Advocacy Rate
the customers who do more than stay — they actively vouch for you.
Why This Actually Works
Not another glossary. A system for how to think.
Every metric ends with 3 real interview questions, a weak answer next to a strong one, and why the strong one works.
“Our K-factor is 0.4. Should we consider our referral program a failure?”
“Yes, since it's below 1, the product isn't growing virally.”
“Not necessarily a failure. Most products run below K=1, and referral can still be a meaningful, healthy contributor to growth even without achieving pure viral, self-sustaining growth on its own.”
