When you need to hire more people fast, you usually have to spend a lot more money. But in mass recruitment, a larger budget often leads to a flood of useless clicks and a skyrocketing cost per applicant. The partnership between Jooble and ITZU proves you can break this cycle. ITZU scaled its job ads and applicant volume while keeping their average Cost Per Applicant (CPA) exceptionally low, beating their corporate target by a massive 80%.
Since April 2025, the Jooble team has been working closely with ITZU to fill their most urgent, hard-to-fill blue-collar pipelines. Instead of guessing which job boards might work, we tracked real-time results and adjusted campaigns on the go. Here is the simple breakdown of what we achieved and how we did it.
Key Takeaways
- Scaling is Predictable: You can increase your recruitment budget safely without sacrificing the quality of your applicants.
- Cost Reduction: ITZU set a tight budget per candidate. Jooble delivered a stable average cost that was over five times lower than the client’s strict corporate target.
- Blue-Collar Precision: We secured a steady flow of qualified workers in tough industries: Automotive, Construction, and Food Production.
Quick Performance Summary (April 2025–Present)
| Campaign KPI | What ITZU Needed | What Jooble Delivered | The Business Impact |
| Cost Per Applicant (CPA) | Strict corporate target ceiling | Stable average | 80% reduction in cost-per-applicant |
| Recruitment Volume | More candidates fast | Significant Increase | Filled shifts without losing quality |
| Top Sectors | Blue-collar workers | Automotive, Construction, Food Production | Steady pipelines for hard-to-fill roles |
The Big Wins: How We Fixed the Sourcing Strategy
In mass hiring, simply spending more money on standard job boards usually results in paying for many clicks that never turn into applications. Here is how Jooble and ITZU changed the game:
Win 1: Paying Only for Real Applicants, Not Random Clicks
- The Problem: Traditional job boards often charge you a flat fee to post a job for 30 days, regardless of whether anyone opens it or applies.
- How we fixed it: We switched to a performance model. Jooble’s system actively looked for candidates who were specifically searching for roles like Productie Operator at that exact moment. ITZU only invested budget when there was real, high-intent interest. This simple shift brought the average cost per applicant.

Win 2: Increasing the Budget Safely Without Getting Spam
- The Problem: If you double your ad budget overnight, you usually get flooded with irrelevant resumes that waste your recruiters’ time.
- How we fixed it: We expanded the budget step-by-step. We didn’t throw money at all jobs at once. Instead, we increased spending only on specific roles (like Couvreur in a particular region) after making sure the current application quality was excellent. This kept the talent pool clean and relevant as volume grew.
Win 3: Finding Workers Who Use Different Job Titles
- The Problem: Blue-collar workers don’t always use the exact “corporate” terms in their resumes. A mechanic might write “garage technician” or “car repair” instead of Automecanicien.
- How we fixed it: Jooble’s search engine understands what candidates mean, not just the exact letters they type. By connecting related skills and synonyms, we displayed ITZU’s vacancies to qualified local specialists who would have otherwise been missed by standard keyword filters.
The Blue-Collar Hiring Checklist: Tips for Your Team

If you are recruiting for manufacturing, logistics, or construction, you can replicate this success by applying these three simple rules today:
- Stop Buying 30-Day “Ghost” Slots. If a platform wants upfront money for a job ad with no guarantee of results, walk away. Look for pay-per-performance models where your budget is tied to candidate activity.
- Put Shift and Location Info First. Blue-collar candidates look for short commutes and clear hours. Put the exact location and shift patterns in the first three lines of your job ad, not at the bottom.
- Make the Mobile Application Short. Over 50% of your candidates search on their phones. If your application takes more than a couple of minutes or requires uploading a desktop file, most of your potential workers will close the tab.
Your Next Step: Check Your Costs
Look at your recruitment spend over the last month. If your blue-collar acquisition costs are skyrocketing without delivering a matching lift in actual candidate quality, you are overspending on empty traffic. Try isolating a single difficult job category and testing it on a performance-driven pipeline for 30 days.
