The document discusses the need for improved digital media measurement metrics that focus on effectiveness rather than just impressions or clicks. It argues that online surveys often provide misleading data due to sampling biases, and that viewability alone is not a sufficient metric as it does not measure outcomes like ad recall, attitudes, or sales lift. The document advocates for cross-platform measurement of unduplicated audiences and effective frequency to better plan campaigns across devices.

28. Implications for Excessive Frequency
v Frequency caps from 20 to 50 are appropriate for most brands
v Exposures above those thresholds are, at best, wasted
v The marginal contribution of an incremental exposure declines quickly
and loses over 90% of its effectiveness even earlier
v The thresholds for wasteful or harmful effects are likely to be lower for
interruptive advertising such as online video ads or pop-up ads
