Not all job boards are worth the spend. Add your sources below to compare cost per hire and conversion rate side by side, then see the formulas and how to reallocate budget toward what's actually working.

Job board effectiveness comes down to two numbers looked at together — what each hire cost, and what share of applicants actually converted.
Cost per Hire = Spend ÷ Hires
Hire Conversion % = (Hires ÷ Applications) × 100
Looking at either metric alone can mislead you. A source with a low cost per hire might simply be producing very few hires from a huge, low-quality applicant pool. A source with a high conversion rate might still be expensive per hire if application volume is low. Comparing both together separates genuinely efficient sources from ones that only look good on one dimension.
Example: $500 spent on a niche board that produces 3 hires from 60 applications works out to a $167 cost per hire and 5% conversion. $2,000 spent on a broad job board producing 4 hires from 400 applications works out to a $500 cost per hire and 1% conversion — the niche board is the better source even though it produced fewer total hires.
| Source type | Typical conversion range |
|---|---|
| General-purpose high-traffic job boards | Under 1% |
| Niche or role-specific job boards | 1% – 3% |
| Employee referrals | 3% – 8%+ |
| Direct sourcing / talent pipelines | Varies widely by pipeline quality |
It measures how well a job posting source converts spend into hires, typically assessed using cost per hire and hire conversion rate side by side.
Cost per Hire = Spend ÷ Hires. Divide total spend on that board by the number of hires it produced in the same period.
Hire Conversion % = (Hires ÷ Applications) × 100 — the percentage of applicants from a source who ultimately became hires.
General high-traffic boards commonly convert well under 1% of applicants; niche boards and employee referrals often convert several times higher because the applicant pool is more pre-qualified.
A source can look good on one metric while being weak on the other — comparing both together shows which sources are genuinely efficient rather than winning on a single dimension.
Most teams review quarterly or after each major hiring cycle, since performance shifts with seasonality, role mix, and changes to a board's traffic and pricing.
Reallocate spend toward the lowest-cost, highest-conversion sources, cut or renegotiate underperformers, use niche boards for specialized roles, and track performance by role type.
