How to reduce recruitment marketing costs without losing performance

Recruitment budgets are under pressure. Marketing spend is being scrutinised. And yet the demand to hire and hire well hasn’t eased.

If your ad budget feels stretched but results aren’t improving, you’re not alone.

Across every sector, we’re hearing the same thing: rising costs, unclear ROI, and growing expectations. This post breaks down how to reduce recruitment marketing costs without cutting results, and why performance-led platforms like Gaia are now the smarter, leaner way to hire.

Why recruitment ad costs are rising

Hiring teams are spending more to get less. Here’s why:

  • Auction competition is up. More advertisers are bidding on the same audiences.
  • Legacy platforms charge flat fees without optimisation, meaning you’re stuck with fixed costs and no guarantee of performance.
  • Job boards deliver volume, not value. And filtering irrelevant applications takes time and resource.
  • No retargeting. Candidates who drop off rarely come back, unless you pay again.

The result? Inflated costs, lower ROI, and strained teams trying to justify spend.

Where money is being wasted

One of the most common and costly issues in recruitment marketing is ad spend inefficiency. The average cost-per-hire continues to climb, but the actual quality of applications often doesn’t keep pace. Teams end up paying for traffic, not talent.

Poor targeting leads to ads being shown to the wrong audiences. Flat-fee models with no performance insight leave teams blind to what’s working. Job boards flood inboxes with irrelevant CVs, forcing hours of manual filtering.

And when a strong candidate drops off mid-journey, most platforms offer no way to bring them back unless you start the spend cycle all over again.

These leaks add up fast. Whether you’re paying per post or per click, if those clicks don’t convert, they’re wasted. And when cost-per-application goes up while conversion-to-hire stays flat, it’s your budget and your team that takes the hit.

Budget leaks usually happen in three places:

  1. Channels that can’t adapt. Job boards and flat-fee media spend don’t flex to what’s working.
  1. No performance insight. You can’t see where your spend goes, or what converts.
  1. Poor creative and apply UX. Even the right audience won’t convert if the journey is slow, generic, or off-brand.

Cutting spend across the board won’t fix this. But redirecting it to what performs will.

What a performance-led approach looks like

Reducing spend doesn’t mean reducing reach or quality. It means:

  • Running ads only where they convert
  • Automatically shifting budget to top-performing platforms and creatives
  • Using data to learn, adapt, and optimise…in real time
  • Making apply journeys frictionless, so more people complete

This is what performance-led recruitment looks like. And it’s how smart teams are hiring better while spending less.

“Gaia’s AI-driven strategy helped us reach the right talent faster, overcoming location and skills shortages while strengthening our employer brand. Their precision targeting and data-driven approach made a real difference in how we attract and engage candidates.” Babcock

Indeed, Babcock’s campaign performance speaks volumes:

Why now is the time to make the shift

Hiring isn’t slowing down, but budgets are. That’s forcing TA and HR teams to rethink how they invest.

The old model of flat fees, job board reliance and no visibility just doesn’t work anymore. It’s too slow, too expensive, and too opaque.

Shifting to a performance-led model means:

  • Lower ad spend and wasted budget
  • Higher quality, more relevant candidates
  • Faster time-to-fill
  • Significantly reduced CPA and CPH
  • Clear, measurable ROI

This means you're attracting talent that fits, all without needing a bigger team or agency retainer.

Who this helps most

  • Employers looking to cut costs without cutting quality
  • Finance and TA teams needing clear ROI
  • Companies running high-volume recruitment or hard-to-fill roles
  • Brands moving from agency to in-house or hybrid models
