Click-through rate (CTR)
Click-through rate is the share of people who clicked your ad out of everyone who saw it, calculated by dividing clicks by impressions and multiplying by 100. It goes up when your ad stops the scroll and states a clear promise in seconds. It measures ad appeal, not proof that the product will sell.

The formula
Click-through rate = (Number of clicks ÷ Number of impressions) × 100
- Number of clicks: clicks that led to your page.
- Number of impressions: how many times your ad appeared on screen.
- Result is a percentage: 2% means two clicks per hundred impressions.
Worked example
What does improving CTR do to visitor cost?
- 1An Egypt store spends 20,000 EGP weekly and gets 200,000 impressions.
- 2First video: 3,000 clicks → CTR = (3,000 ÷ 200,000) × 100 = 1.5%.
- 3Cost per click = 20,000 ÷ 3,000 ≈ 6.7 EGP.
- 4New video with different opening: 5,000 clicks → CTR 2.5%.
- 5Cost per click = 20,000 ÷ 5,000 = 4 EGP.
Takeaway: Same budget, same impressions: raising CTR from 1.5% to 2.5% cuts visitor cost from 6.7 to 4 EGP.
What it means in practice
Click-through rate measures one thing: did the ad deserve to stop the scroll? It moves mainly on the first two seconds and clarity of promise, not budget size. So the fastest way to improve it is to change your video opening or first sentence, not change your targeting.
High CTR with few orders is a useful diagnostic signal: the ad promises something your page doesn't deliver. Check that your headline, image, and price match between the ad and your order form before you blame the audience or the platform.
CTR declining gradually on the same audience signals ad fatigue: people who saw it repeatedly stopped engaging. The fix is to refresh the creative or expand your audience, not to spend more on an exhausted ad.
Common mistakes
- Chasing high CTR with exaggerated headlines or shocking images: you get curious clicks but confirmation rate collapses because the buyer feels tricked.
- Comparing CTR between different placements, like a short video versus a news feed, as if they're the same metric.
- Reading the rate on just hundreds of impressions and making a decision: small numbers swing wildly and lead to wrong conclusions.
- Focusing on CTR alone and ignoring what percentage of visitors actually submit an order form.
Questions and answers
What's a good click-through rate?
No universal number works; CTR differs by platform, placement, product type, and country. Your only useful reference is your own account: compare a new ad to the average of your past ads on the same platform and audience.
Why is my CTR high but sales are weak?
Usually because your ad's promise doesn't match the page: different price, a prettier photo than reality, or a feature that doesn't show up in your order form. Check the first screen a visitor sees and make sure it continues the sentence that attracted them.
How do I raise CTR fast?
Change the first two seconds. Test three different openings of the same video: a direct question, an immediate visible result, and an answer to a common objection. Keep the rest of the ad the same until you know which opening did the lifting.
Does high CTR lower impression price?
Usually yes, indirectly, because platforms give engaged ads broader reach on the same budget. But the sure and immediate effect is lower cost per click, since the same impressions now yield more clicks.
