What is Source of Hire?
Source of hire identifies the channel or method credited with bringing a successful hire or placement into the recruiting process. Agencies use it to understand where placements originate and where future sourcing time or budget may be best spent.
Source-of-hire reporting depends on a consistent rule for assigning each placement to a source.
How source of hire works
Record an origin when a candidate enters the database or a specific search, then connect that source to the eventual hire. Examples include referrals, job boards, direct sourcing, events, and existing candidate relationships. Agree whether the report attributes the placement to the first known origin, the source for the current job, or another documented rule.
These choices answer different questions. An individual first met at an event may later respond to an email about a new role. The first source describes how the relationship began; the current-search source may describe how the person entered that particular opportunity. Neither alone captures every influence.
How to calculate it
For a defined group of completed hires, divide hires attributed to a source by all hires in the group, then multiply by 100. If 8 of 40 placements are attributed to referrals, referrals account for 20% of those placements. Use a consistent period and state whether the date is the offer acceptance, start date, or another agreed event.
Also track unrecorded or unknown sources. Removing missing records from the denominator can make a channel look more important than the available data supports. If attribution is uncertain, mark it as unknown rather than inventing an origin.
Source of hire versus source effectiveness
Source of hire describes the mix of successful outcomes. Source effectiveness asks how efficiently a channel produces relevant progress, such as qualified conversations or placements relative to people sourced, effort, or cost. A channel may create many hires because the agency invested heavily in it, even if another channel produces a higher conversion rate.
Use source-of-hire analysis alongside conversion, search context, and the cost or time required to use each channel. Avoid judging a channel by response volume alone.
Example for a search firm
An agency fills ten comparable assignments: four hires came from referrals, three from existing database relationships, two from direct sourcing, and one from an advertisement. The team checks the source rule and discovers that the existing-database group includes people first introduced through several earlier channels.
The agency can report database rediscovery as the current-search source while retaining original acquisition source separately. It should not conclude that the database created those relationships by itself. The two fields help the team understand acquisition and reuse.
How to improve source data
- Define a short set of source categories that recruiters can apply.
- Decide whether the field records first origin or entry to a particular search.
- Capture the source near the time of entry and preserve it through stage changes.
- Review missing and inconsistent values before reporting.
- Compare comparable roles, search models, and completed cohorts.
- Use findings to test a channel decision and revisit the outcome.
Common mistakes
Overwriting the original source during a profile update can erase relationship history. Mixing source categories such as “LinkedIn” and “direct sourcing” can also lead to double counting because one describes a platform and the other describes a method. Keep taxonomy clear and document how mixed cases are handled.
Do not compare one specialist retained search with a high-volume campaign as if they were interchangeable. Seniority, geography, compensation, and client process can affect both channel availability and outcomes.
Technology and interpretation
An applicant tracking system can store source fields and connect candidate activity to jobs. Automating capture can reduce missing data, but the team still needs definitions and checks. Multi-touch attribution can add useful context, but it requires reliable interaction records and should not imply a causal result by itself.
Questions recruiters ask
Is the largest source always the best?
No. Compare the quality and cost of outcomes, the number of opportunities, and the type of search.
Can a candidate have more than one source?
Yes. Store original acquisition and current-search entry separately if the workflow supports it, and explain which one the report uses.
