The Indonesian app market is plagued with costly fraud. In the first quarter of 2019, financial exposure to mobile fraud in the Travel vertical has already topped $9M with 36% of all installs marked as fraudulent.

However, this number is decreasing in comparison with Q4 2018, at least for the companies using an advanced ad fraud prevention solution. was first founded in 2011 in Indonesia and is today one of the country’s top travel management platforms. In the past 3 years, their growth has been tremendous: their active user base has grown by 200%, while install rates increased 10X YoY in 2017, and 2X YoY in 2018.


With this massive growth in a very short time, realized a disturbing trend: the number of user registrations was much lower than the install count. The trend indicated a high likelihood of fraudulent clicks and installs.

These clicks were clicks was paying advertising networks for, and clearly this money was going to fraudsters.

The team had no way of knowing which of the ad networks they were working with were responsible for this behavior, and required an advanced prevention system that could help clean up their data and save the money that is otherwise going to fraud.

“We started using email, phone numbers and other channels as a proxy to measure LTV,” states Dyah Wulandari, VP Performance Marketing at

But it was no easy task.

Wulandari continued noting, “We first needed to deal with the hundreds of invalid clicks and suspiciously-short CTITs. In Indonesia, where the majority of users don’t have a high-speed internet connection, we were able to recognize patterns in CTIT that didn’t make sense. We needed to address this with the problematic ad networks; fraud was costing us a lot of money. Moreover, it was really time consuming for our team; they needed to work for hours just to clean up numbers which we had thought were genuine. We tried to manually review these anomalies and send them back to our partners, but it was a nightmare”. mobile ad fraud

The solution also allowed us to combine the data with our internal data (e.g. transaction records, AOV).

The problem is real and huge and has significant repercussions on the marketing budget and team. Your choice of provider for blocking fraud needs to be a solution recognized by the market as the leading one, it must be based on a great amount of data and able to learn over time as fraud always evolves.”
