"Think of it like counting window-shoppers vs. people who walk in."
How it works
CTR = Clicks ÷ Impressions × 100

Test headlines and thumbnails first — they move CTR most
Real-world example
Your Instagram ad reaches 10,000 people and gets 230 clicks. That's a 2.3% CTR. Above 2% is solid for most social ads; above 5% means your hook is genuinely working.
