A report by an online advertising and Internet security firm stated that up to $9.5 Billion in online advertising in 2013 could be wasted by displaying ads to bot traffic.
Up to 46 percent of Web-based ad impressions in 2013 could be displayed to suspicious and malicious traffic that is controlled by botnets. 35 percent of mobile-based ad impressions may be bots as well, according to Solve Media.
In 2012, the rate of ad impression for the web and mobile was 43 percent and 22 percent.
The report stated that the highest levels of suspicious traffic for Web-based ads originated from China, Venezuela and Ukraine. For mobile-based ads, the bot traffic originated from Singapore, Macau and Qatar.
In the United States, 44 percent of web-based ad impressions was considered suspicious in the second quarter of 2013, and 22 percent for mobile-based ads.
