Cost per acquisition
Ad costs rise as competition increases, and you pay for every click whether it converts or not. Referrals cost nothing up front — you only share value when a deal actually closes.
Lead quality
Referred leads arrive pre-qualified and trusting. That means shorter sales cycles, higher close rates and clients who stay longer.
Durability
Turn off your ads and the leads stop the same day. Referral relationships keep producing deal flow long after the initial effort — they compound instead of resetting.
