What these metrics mean
CTR, click-to-conversion, and impression-to-conversion show where drop-off happens. CPC, CPA, and ROAS show cost efficiency.
How to calculate
CTR = Clicks ÷ Impressions × 100. Click-to-conversion = Conversions ÷ Clicks × 100. CPC = Spend ÷ Clicks. CPA = Spend ÷ Conversions. ROAS = Revenue ÷ Spend.
How to improve
Improve CTR (creative, targeting). Improve conversion rate (landing page, offer, UX). Lower CPA by improving conversion or targeting. Increase ROAS by margin or conversion.
Common mistakes
Attributing all revenue to one channel; using different time windows for spend and revenue; or mixing view-through and click-based conversions without noting it.
How to interpret
Compare rates across campaigns and steps. Find the biggest drop-off (impression→click or click→conversion) and fix that first.
