・COVID-19 Cases and Ad Fraud in Japan

The coronavirus pandemic has persisted in Japan since January 2020, but the rate of infection reached its peak from mid-March until the end of April. Although the number of infections decreased in May, infections gradually increased again in July, sparking second wave conversations. The rapid increase in COVID-19 cases has negatively affected app installs.

A temporary decline in the ad fraud rate in March and April correlates with the sudden changes in advertising budget and targets that were in response to COVID-19. As we are forced to coexist with the virus in this so-called “after corona” era, it has been observed that the ad fraud rate is gradually increasing despite advertisers remaining hesitant in increasing advertising budgets to “before corona” times.
