frequency capping, are overstating reach investment because CTR ignores the
and understating frequency because UK behavioural/attitudinal change over time
users are having 3rd party cookies deleted that display exposure drives

18. Summary
Reporting campaign effectiveness on CTR alone fundamentally
undervalues the role online display has in influencing consumer
behaviour
Effective campaign measurement considers the requirement of
each advertiser brand and reports accordingly
Proper reporting and use of data can help publishers justify
appropriate display rates, and agencies and brands understand
the real value they obtain
