Vertical: Fintech / Business Finance | Offer: Account registration + first deposit | GEO: Thailand 🇹🇭
This article is the second part of our case study. In the first part, we covered Scaling Fintech FTDs in Malaysia. We recommend you read it as well!
Why Thailand? The Lowest CPA We’ve Seen Across SEA
Choosing Thailand is not the typical choice when it comes to Fintech market. English proficiency is even lower than in Malaysia. The regulatory environment is also quite strict. Besides, the creative level is much higher. You can’t just translate a global ad and expect it to work here.
But if you do the right thing for Thailand, the result will be hardly arguable.
We conducted this campaign in Thailand and it was the lowest CPA campaign of any GEO we ran during this period. $17-$27 per first-time depositor, on an offer that was shared at an even higher price. The margin was there from the third day of the testing and it remained at the scale.
The main reason isn’t luck. It’s a market where most affiliates are not investing localization enough. So, the ones who do their localization properly experience far less competition for quality inventory.
Besides, Thailand is also characterised by a unique digital behaviour profile. LINE is the most popular communication channel here. Most people use Android for mobile. Facebook usage here is different from anywhere else in SEA. Only by understanding those subtleties a campaign can be a winner instead of just bleeding a budget.
Campaign Setup
| Parameter | Details |
|---|---|
| GEO | Thailand 🇹🇭 |
| Traffic | Facebook (primary) + Native |
| Device | Mobile-heavy (Android dominant) |
| Offer Type | Fintech account signup + first deposit |
| Funnel | Pre-lander (bonus + cashback angle) → Offer LP |
The setup looks similar to a standard SEA Fintech campaign. The execution required a completely different mindset.

Strategy: What Led to the Results
1. Fully Thai Localised — No Half-Measures
Non-English, especially Thai, ad creatives registered a 3.4x higher CTR than English versions targeted at the same audience. This is not a slight increase. It is the breaking point between a successful campaign and a failing one.
Localisation here refers to colloquial Thai. The language register which normal people use in their daily lives as opposed to formal or translated English ones. Thai people can distinguish the difference right away, and it is the first factor leading to whether they trust what they are reading.
2. Bonus and Cashback Framing Was More Effective
While feature-led ad copies only modestly increased interest compared to simple product descriptions, coupons and limited-time deposit bonus incentives habitually scored the highest.
Offering a bonus changes the whole frame of the conversation: rather than “should I believe in this platform?“, the user becomes “what is the worst outcome of trying this?” And it’s certainly a lot easier to give a positive answer.
Continued use of urgency overlays “offer ends tonight” or similar wording, on the page with promotional material attracted about an eighteen percent increase in conversion rate (CVR). No contest. If you give people a specific deadline, they are much more likely to get off their butts than if you just make a vague reference to urgency.
3. LINE as a Trust Sign
LINE is much more than a messaging app in Thailand. It is the platform on which the support of the customers is given, brands are followed, and their buying decisions are finalized. Ads and pre-landing pages mentioning a LINE presence not only had better performance but also recorded considerably better results.
For a user making a deposit for the first time, seeing LINE as a method of contact strongly communicates that there is an actual local team that is standing behind this platform, and the user would be interacting with a real person.
4. Facebook Feed + Stories as Separate Channels
Feed brought in the highest volume of cold traffic. Stories were able to close the sale of warm users who had already visited the pre-lander. Overall, running both with new format-matched creatives, square for Feed, vertical for Stories, turned out to be a 22% improvement in blended CPA versus single-format campaigns.
Native ads were run alongside both, feeding the retargeting pool at low CPM without burning Facebook budget on cold audiences.
The Pre-Lander: Bonus, Not Education
The pre-lander focused on selling the bonus (numbers on the spot, direct and to the point) and then at length, on the platform (changing descriptions, benefits) and distinguishing the product + the process of getting the bonus made first focus.
At every step, the story was consistent. The user saw a cashback offer, was taken to a page that further elaborated the offer, and finally went to the offer-to-claim page. Only one unified and coherent path — not three isolated pieces.
One single CTA. There wasn’t a second link. The page was designed for Android mid-range devices on 4G — the actual device and connection profile of the target audience.
Performance Data
| Metric | Result |
|---|---|
| CPM | $0.90 – $1.60 |
| CTR | 2.1% – 3.8% |
| CVR (FTD) | 8% – 14% |
| Avg. Deposit | $100 – $150 |
| CPA (FTD) | ~$17 – $27 |
Managing to keep CPM under $1.60 for Fintech is just amazing. A related local creative that is finely tuned will hold the relevancy scores high and keep CPMs low — in fact, generic English creatives showed roughly half the CTR and significantly higher CPMs.
The CVR of 8–14% is honest proof that the bonus pre-lander is working properly. LINE, as a trust signal, has helped to reduce the KYC drop-off, typically the main reason why Fintech funnels in this market lose volume.
Important Insights for Affiliates
✅ Using everyday Thai is absolutely mandatory. Don’t just translate. Make it local. The difference in CTR is simply too big to disregard.
✅ Your first point should be the bonus. Cashback and limited-time offers are the main reasons for conversions in this market, not only the features or the credibility of the platform.
✅ Mention LINE. If the platform operates a LINE account, put it in your creative and pre-lander. It truly works as a trust factor.
✅ Separate Feed and Stories. Consider them as two different channels with their separate creatives. It is 22% better CPA and justifies the additional production effort.
✅ Try provincial targeting. Chiang Mai, Khon Kaen, and Phuket are getting lower CPMs and are also the places with increasing investment interest. So, don’t limit your geo to just Bangkok.
Final Thoughts
Thailand is indeed one of the most lucrative Fintech markets in Southeast Asia and at the same time, one of the strictest about poor execution.
Those affiliates who consider the market as a mere copy-paste from Malaysia or the Philippines are going to lose a lot of money and eventually give up. However, the ones who properly localise, create a bonus-driven funnel, and have an insight into the way LINE and Facebook work together in the Thai user’s decision-making will get the lowest CPAs in the region, if not in the world.
$17–$27 CPA on FTD. Day three confirmation. Maintained at scale.
The recipe isn’t really that hard. But it demands that you do the groundwork. Creative localisation, pre-lander architecture, placement strategy, WELL BEFORE you start spending. Thailand gives the greatest advantage to those who prepare amongst all the GEOs we run.
