Facebook Ads Case Study: How a Recruiting Company Cut Ad Spend 43% While Nearly Tripling Applications

A shift to Facebook’s unpublished post targeting turned a shrinking, underperforming campaign into record months for both traffic and applications.

Quick summary: In this Facebook ads case study, a recruiting company in the truck driver industry grew website traffic 170.78% and applications 254.54%, while cutting monthly Facebook ad spend 43%, from $2,800 to $1,600, by switching from standard boosted posts to Facebook’s unpublished post targeting.

Introduction

This Facebook ads case study looks at a recruiting company in the truck driver industry, an environment where finding qualified drivers consistently is a constant, high-stakes challenge. Facebook wasn’t a side channel for this business. It was already responsible for 45.7% of website traffic and 24.7% of completed driver applications before this campaign began, which meant a decline in Facebook performance was a real business problem, not a minor metric to shrug off.

The Challenge

Heading into the summer, both website traffic and application conversions coming from Facebook had dropped dramatically. Because Facebook already carried such a large share of the company’s overall lead flow, that decline was putting real pressure on the business’s ability to recruit new drivers. The goal was direct: increase both traffic and applications from Facebook, while lowering the ad budget at the same time, not growth funded by spending more.

Our Strategy

Switching to unpublished post targeting

Instead of boosting posts and running standard ads, the campaign shifted to Facebook’s unpublished posts, often called dark posts. These are ads that run without ever appearing on the company’s public page timeline, which made it possible to test and target many different ad variations toward the most relevant audience possible, without cluttering the page itself with every version being tested.

Weekly optimization, not a single launch

Rather than setting the campaign and checking back occasionally, weekly meetings were built into the process specifically to review ad performance and refine reach and engagement on an ongoing basis. Continuous iteration, not a one-time setup, is what improved both the amount and the quality of website clicks over time.

The Results

By the campaign’s third full month, both traffic and applications hit record highs, while the monthly ad budget was smaller than it had been before the campaign even started.

Key results at a glance:

• Website traffic grew 170.78%, from 3,299 sessions in June to a record 8,933 sessions in September
• Applications grew 254.54%, from 44 in June to a record 156 in September
• Monthly ad spend dropped 43%, from $2,800 to $1,600, a projected annual savings of $14,400
• Unpublished post ads delivered 12,829 website clicks at $0.21 per result, reaching 280,134 people
• Both traffic and applications hit record monthly highs in the campaign’s third full month

What Business Owners Can Learn

• Being heavily dependent on one marketing channel isn’t automatically a mistake, but it does mean that channel needs consistent, active management rather than being left alone.
• Unpublished post ads can outperform standard boosted posts by allowing precise, tested targeting without cluttering a page’s public feed with every ad variation.
• A new strategy can look worse before it looks better. A short dip in the first month isn’t necessarily a sign of failure.
• Growth and cost reduction aren’t always a trade-off. When the original problem is imprecise targeting, fixing that can improve both at once.
• Weekly review and optimization compounds over the life of a campaign in a way a one-time setup never does.

Frequently Asked Questions

What are Facebook unpublished posts and why use them for ads?

Unpublished posts, sometimes called dark posts, are Facebook ads that run without appearing on a page’s public timeline. That allows an advertiser to test and target many different ad variations toward specific audiences without cluttering the page itself with every version. In this case study, switching from boosted posts and standard ads to unpublished post targeting was the central strategy change that improved both results and cost efficiency.

Can you increase Facebook ad results while lowering ad spend?

Yes, when the original spend was going toward broad, imprecise targeting. In this case study, website traffic grew 170% and applications grew 254%, while monthly ad spend was reduced 43%, from $2,800 to $1,600 a month. The gains came from more precise audience targeting, not from spending more.

Is it risky to rely heavily on Facebook for recruiting or lead generation?

It can be, if that reliance isn’t actively managed. In this case study, Facebook was already responsible for 45.7% of website traffic and 24.7% of applications before the campaign began, so a decline in Facebook performance was a real business problem, not a minor metric dip. Heavy reliance on one channel isn’t necessarily wrong, but it does mean that channel needs consistent, active attention.

How long does it take to see results from a new Facebook ad strategy?

It can take more than a single month, and results don’t always improve immediately. In this case study, conversions actually dipped slightly in the first month after the new strategy launched, before climbing sharply over the following two months as the targeting was optimized. A short-term dip right after a strategy change isn’t necessarily a sign it isn’t working.

Final Thoughts

None of this came from spending more to fix a shrinking campaign. It came from changing how the budget was being spent, testing relentlessly through unpublished posts, and reviewing performance weekly instead of hoping the campaign would recover on its own.
