Fraud rates are dynamic and are based on many different factors. Industry is one of the largest factors in the amount of fraud you are likely to receive.
The more competitive the industry the higher the fraud rates usually will be.
For instance, we typically see extremely high fraud rates in on-demand services such as locksmiths, plumbers, HVAC, pest control and on-demand repair businesses where every click has huge competition, (sometimes over 50% fraud rate).
Other industries with high cost per clicks such as Law/Legal, Real Estate and Insurance also see high fraud rates (just over 20% fraud rate on average).
E-commerce and retail type businesses typically see a lower overall fraud rate (around 10% fraud) but a higher percentage of bot/fraudulent device activity.
Fraud rates will change depending on your location, market size, and the amount of competitors bidding on your keywords.
