Click-Through Rate (CTR) Calculator
Click-Through Rate (CTR) is a key metric used in digital marketing, particularly in advertising and email campaigns. It measures the percentage of people who clicked on a specific link or call to action (CTA) after seeing it. A higher CTR generally indicates that your ad or content is relevant and engaging to your target audience.

Understanding Click-Through Rate
The formula for calculating Click-Through Rate (CTR) is straightforward:
CTR = (Number of Clicks / Number of Impressions) * 100
Let's break down the components:
- Impressions: This refers to the total number of times your ad, link, or content was displayed to users. Each time someone sees your ad, it counts as one impression.
- Clicks: This is the total number of times users actually clicked on your ad, link, or CTA.
A good CTR can vary significantly depending on the industry, platform, and type of campaign. However, a higher CTR generally suggests that your marketing efforts are resonating with your audience, leading to more traffic and potential conversions. Continuously monitoring and optimizing your CTR can lead to better campaign performance and a more efficient use of your advertising budget.
Example Calculation:
Imagine you ran an online ad campaign that received 10,000 impressions, and users clicked on the ad 500 times. To calculate the CTR:
CTR = (500 clicks / 10,000 impressions) * 100 = 5%
In this example, the Click-Through Rate is 5%. This means that for every 100 times the ad was shown, it was clicked on 5 times.
function calculateCTR() {
var impressions = document.getElementById("impressions").value;
var clicks = document.getElementById("clicks").value;
var resultDiv = document.getElementById("result");
// Clear previous results
resultDiv.innerHTML = "–";
// Validate inputs
if (isNaN(impressions) || impressions === "" || isNaN(clicks) || clicks === "") {
resultDiv.innerHTML = "Please enter valid numbers for impressions and clicks.";
return;
}
if (impressions <= 0) {
resultDiv.innerHTML = "Impressions must be a positive number.";
return;
}
if (clicks impressions) {
resultDiv.innerHTML = "Clicks cannot be greater than impressions.";
return;
}
// Calculate CTR
var ctr = (parseFloat(clicks) / parseFloat(impressions)) * 100;
// Display result, formatted to two decimal places
resultDiv.innerHTML = ctr.toFixed(2) + "%";
