How to Lower Your Cost Per Acquisition: Lessons From an 86% Drop
When acquisition costs plateau, the answer usually isn't more budget. Here's the thinking that took one brand's cost per request from S$25.30 to S$3.49.
Rising cost per acquisition is the most common reason a growing brand's marketing stalls. The instinct is to spend more. Usually that's the wrong move — it just buys the same expensive outcome faster. Here's a more reliable way to think about lowering CPA, using a real example.
The situation: search had hit its ceiling
A regional cross-border logistics brand was running acquisition in Singapore and Malaysia on Google Search. Search is excellent at one thing: capturing demand that already exists. Someone typing 'ship from US to Singapore' is most of the way to converting.
But that pool is finite. The high-intent keywords are competitive, bids rise as you push for volume, and there are only so many people searching for a service they may not know exists. Their cost per request had settled at S$25.30 and wasn't coming down.
The shift: match the channel to how the product earns trust
The product was something you have to show, not a keyword you bid on. So we moved acquisition to Meta video in the same two markets — keeping the markets identical so the comparison stayed clean.
A 15-second video can walk through the entire loop — order from any overseas store, ship to a local address, receive it at home — in a way a text search ad never can. And Meta reaches the much larger group of people who'd never think to search for the service, but light up the moment they see it.
The lever: creative, tested at volume
We treated creative as the primary lever, not bids. Several video angles ran against each other — the 'this store doesn't ship here' frustration, the savings math, the unboxing payoff — each cut for the feed. Spend concentrated on the winners; the losers were killed quickly.
Cost per request fell from S$25.30 to S$3.49 — an 86% reduction, roughly a 7× efficiency gain on the same outcome. Crucially, budget didn't go up. The win came from the right channel and relentless creative testing, not more money.
How to apply this to your account
Ask three questions. One: is my channel capturing demand or creating it — and which does my growth actually need? Two: is my product something people search for, or something they need to be shown? Three: am I testing enough creative to find a winner, or betting everything on one or two ads?
Lower CPA almost never comes from a single clever tweak. It comes from matching the channel to how your product earns trust, then testing creative at enough volume to find what works. That's the whole playbook.
FAQ
- What is a good cost per acquisition?
- It depends entirely on what a customer is worth to you and your margins — there's no universal number. The useful question isn't 'what's a good CPA' but 'is my CPA falling as I optimize, and is it well below my customer lifetime value?'
- How can I lower CPA without spending more?
- Usually by matching the channel to how your product earns trust, leading with creative rather than bids, and testing enough variations to find winners. In the example here, CPA dropped 86% with no budget increase by moving from Google Search to tested Meta video.
