What metrics prove employer brand ROI?

The metrics that persuade finance are the ones with money attached: cost-per-hire, time-to-fill, offer-acceptance rate, quality of hire, source-of-hire mix, application-to-hire conversion, retention and referral rates, each tied back to the programme's cost. Falling agency spend and faster fills convert directly into savings, while better retention avoids the substantial cost of replacing people. Track a spread rather than one figure, because any single metric can be moved by factors unrelated to brand. The pitfall is claiming total credit for every improvement; strengthen your case instead by showing consistent movement across several linked measures against a baseline, and being honest about assumptions, which reads as far more credible than one dramatic number.
