From $0.67 per Registration: How We Acquired 19,824 Users for a Freelance Service

How we built a user acquisition system for tester.reviews through Meta Ads — 19,824 registrations at an average cost of $0.67. Niche: freelance service.

Services

Challenge

tester.reviews is an online platform where users complete simple paid tasks: website testing, feature checks, and other easy online actions. The service operates as a freelance platform: registration, moderation, and access to tasks from a smartphone or laptop. The priority market was the U.S. The task was to generate a stable flow of registrations, attract users who would actually complete tasks, and scale advertising without losing efficiency.

Goal

Build a Meta Ads lead generation system optimized for completed registration — Complete Registration. Achieve a low and stable user acquisition cost across three markets: the U.S., the Philippines, and Australia.

Key problems before launch

  • unstable registration cost with no tie to the real target action
  • part of the traffic dropped off before completing registration
  • different geo performance with no dedicated strategy for each country
  • the need to scale without losing user quality

Optimizing for clicks drove traffic, but not real platform users.

Strategy

We launched campaigns optimized for conversion rather than traffic from the very beginning:

  • installed and verified the Meta Pixel
  • configured the Complete Registration event
  • checked data transfer accuracy

The focus was only on real completed registrations, not clicks or reach.

Campaign structure

  • separate campaigns for each geo — USA, Philippines, Australia
  • testing different audiences
  • segmentation by age and interests
  • scaling the best-performing groups

We regularly turned off weak “creative + audience” combinations and kept only those that delivered a stable registration cost.

Communication and creatives

In creatives, we focused on:

  • the opportunity to earn online
  • the simplicity of the tasks
  • working from a smartphone
  • potential hourly income

No complicated promises — just a simple, clear message with a direct registration CTA. We used videos showing how tasks are completed and banners emphasizing income. Creatives were refreshed regularly based on analytics.

Problems and solutions

Unstable registration cost — switched optimization fully to Complete Registration.

Part of the traffic did not finish registration — simplified communication and tested new creative formats.

Different performance by geo — developed a separate strategy for each country.

Result

  • 19,824 registrations
  • $13,390 in ad spend
  • $0.67 average registration cost
  • campaigns launched in 3 geos: USA, Philippines, Australia
  • main focus and best result — USA
