Notes: Suspicious US web traffic was down from a high of 61% in Q4 to 55% in Q1, which Solve Media attributes to lower ad spending after the holiday season. Meanwhile, levels of suspicious mobile activity remained relatively flat quarter-over-quarter. Compared to Q1 2013, though, level of suspicious web and mobile activity have increased. Separately, the report notes that 36% of traffic on automotive-specific sites acted suspiciously; the auto sector accounted for 12% share of online ad spend last year.
