Detection strategy

Detection strategy is a set of filters the 24metrics use to define conversion fraud probability. You can select the needed strategy while creating an Anti-fraud rule.

There are four strategies:

  • Mobile CPI

  • Mobile CPA

  • Lead Offers

  • Ecommerce

Each of them contains a set of filters by 24metrics applied to the selected conversions. Here you can learn more about each filter.

⚠️ Affise doesn't define the filters set within a detection strategy. 24metrics do it on their side.

⚠️ The No configuration options record means the filter is active, but no specific parameters are indicated for it.

Fraud probability

Fraud probability allows defining the conversions to be declined automatically according to the selected options (see below). You can select the needed strategy while creating an Anti-fraud rule.

24metrics calculates scores depending on which type of abnormality the system detected for each conversion. Each type has a certain number of points. As a result, every conversion has its score and the fraud probability. Here you can learn more about what every level means.

⚠️ Affise doesn't influence the scoring process and fraud probability determination and calculation. 24metrics perform it on their side.

There are four options:

  • Do not decline: the system doesn't decline conversions.

  • High: the system declines conversions with the high risk level.

  • Medium and higher: the system declines conversions with the medium and higher risk level.

  • Low and higher: the system declines conversions with the low or higher risk level.
