Recruiting Basics

Sourcing Channel

A sourcing channel is any source or method recruiters use to find and attract candidates, such as job boards, employee referrals, social media, careers pages, recruitment agencies, or direct outreach. Tracking which channels produce hires—known as source-of-hire—helps organizations measure recruiting effectiveness and allocate budget to the most productive channels.

What are common sourcing channels?

Typical sourcing channels include job boards, the company careers page, employee referrals, professional networks like LinkedIn, social media, recruitment agencies, talent databases, and direct outreach to passive candidates. Each channel reaches a different audience: boards and careers pages attract active seekers, while referrals and direct sourcing tap passive talent. Organizations usually blend several channels to balance volume, quality, speed, and cost across different role types.

How do recruiters measure sourcing channel effectiveness?

Recruiters track source-of-hire, which records the channel each hired candidate came from, alongside metrics like cost-per-hire, time-to-fill, and quality-of-hire by channel. Comparing these figures reveals which channels deliver the best candidates at the lowest cost. For example, referrals often yield strong quality-of-hire and retention, while paid boards may generate volume but higher cost. This data guides where to invest recruiting budget.
