21% Lower CPA on +283 Leads, Luxembourgish Specialist Credit Broker, Google Ads

The challenge

A Luxembourgish credit broker specialising in loans and credits needed more qualified leads and better margin per lead, not just more volume. The existing setup was filling the funnel with traffic that converted but didn't translate to profitable sales when measured across channels.

What we did

• Sharpened campaigns down to proven winners, killed underperformers, doubled down on high-CTR units

• Pre-qualified visitors on the landing page to filter out low-intent clicks before form submission

• Added Google Lead Form ads to capture mobile prospects at the moment of intent

• Tracked revenue via offline conversion uploads so optimisation pushed toward real profit, not just lead count

The results

• Total leads: 621 → 904, added 283 leads (+46%)

• CPA: €34.14 → €26.83 (dropped €7.31, -21%)

• CTR: 0.65% → 7.96%, a 12x lift, from below average to exceptional

• Ad spend: €21.25K → €24.3K (+€3,050)

Why it matters

A 0.65% CTR before our work meant the previous campaigns were spraying broad keywords at audiences with no buying intent, burning budget on irrelevant clicks. Lifting CTR to 7.96% (a 12x improvement) signals the campaigns shifted from broad-and-untargeted to precise-and-relevant. Combined with dropping CPA, this is the proof point most credit brokers want, that Google Ads can drive profitable acquisition, not just cheap leads that don't convert.
