Measurement

Click-Through Rate (CTR) — Definition & Explanation

The percentage of ad impressions that result in a user click. CTR = (Clicks / Impressions) × 100. Average display CTR is 0.1-0.3%; native ads achieve 0.5-1%+. CTR is a key performance metric for response-driven campaigns.

How Click-Through Rate (CTR) Works

CTR is measured by tracking pixel fires for impressions and click redirect tracking for click events. Ad servers record both and calculate CTR as part of standard performance reporting.

Why Click-Through Rate (CTR) Matters for Publishers

High CTR improves publisher value for performance advertisers, which can attract higher CPM bids from CPC-converted campaigns. Publishers should optimize placements for viewability first, which naturally improves CTR.
