Measuring Recruiting Channel ROI
Not all recruiting channels deliver equal quality. Employee referrals typically produce the highest-retention, highest-performance hires at the lowest cost. LinkedIn works well for senior roles but is expensive per hire. Job boards are cheaper but produce lower conversion rates.
Track cost-per-hire AND quality-per-channel: retention at 12 months, performance ratings, and time to full productivity. A channel that delivers cheap hires who leave in 6 months has terrible total ROI.
