- Every campaign must have a measurable goal (CAC, CTR, conversion rate, revenue)
- Distribution is as important as content — perfect content with no audience = zero
- Test small, scale what works, kill what doesn't
- Indian consumers respond to: trust signals, value clarity, peer validation (social proof)
- Think platform-native — what works on LinkedIn is terrible on Instagram
