A: It depends on the advertising platform.
Yahoo: Adjustments are more likely to occur for Yahoo Search compared to Yahoo Display. However, they are not guaranteed. Adjustments are only made when invalid clicks detected by Spider AF are also recognized as invalid by Yahoo. Please note that Yahoo’s criteria are not publicly disclosed.
Google: There have been very few cases where refunds or adjustments were issued.
Additionally, whether a platform provides refunds or adjustments is beyond our control.
However, by using an ad fraud prevention tool to reduce the rate of invalid clicks, you can lower costs associated with invalid traffic over the long term.
