Why Clickthrough is a Terrible Engagement KPI

Clickthrough used to be king. Now it's barely a squire.
Display advertising is about delivering value to a brand, whether it means increasing awareness or perception, or nudging consumers further along the purchase funnel. However, the predominant metric in digital advertising continues to be clickthrough rate (CTR), even though it's an unimportant measure of a display ad's effectiveness.
Come again?
I'll repeat: CTR is an unimportant measure of a display ad's effectiveness.
This isn't a matter of opinion.
- Only a small segment of the overall online audience actually clicks on display ads. According to a comScore study, 8% of Internet users account for 85% of all display ad clicks, and 72% are uncomfortable clicking on ads altogether. By measuring clicks, you ignore the impact an ad has on almost three-quarters of your audience.
