Gabe Baptistella: 11,052 conversions at A$0.07 each

The challenge

Grow a Portuguese-language audience from a standing start, with a small budget and no tolerance for spend that produced views but no subscriptions.

Starting position

No paid acquisition running, no conversion tracking configured, and organic growth limited to what the content reached on its own.

What we did

• Defined the conversion event that mattered — a subscription — rather than optimising to clicks or views.
• Built a Performance Max campaign with asset groups matched to the creator's strongest performing content themes.
• Kept the daily budget deliberately low while conversion signals were established, then held it steady once cost per conversion stabilised.
• Reviewed placement and asset performance weekly, retiring assets that drove cheap clicks but no conversions.

Tracking and measurement

Conversion actions configured and validated before launch so the campaign optimised against the real outcome, not a proxy metric.

Results

11,052 conversions from A$795.60 in spend — an average cost per conversion of A$0.07, from 11,017 clicks and 2,518,786 impressions.

What we learned

Low CPA on an audience-growth objective is achievable, but only when the conversion event is defined correctly before launch. Campaigns optimised to clicks in the same account would have spent the same money for a fraction of the outcome.
