Stop letting your digital marketing budget vanish into wasted impressions. Every missed click is revenue walking out the door—your ads, emails, and website are either driving action or bleeding money. That’s why Click-Through Rate (CTR) is the undeniable heartbeat of digital marketing, the single metric that tells you exactly how well your content inspires action across every channel. In this guide, I’ll give you the exact click-through formula and click-through rate calculations for main channels, plus proven strategies to dramatically boost your CTR and turn more impressions into measurable results—so you can stop guessing and start really growing.
What Is Click-Through Rate (CTR)?
CTR, or click-through rate, measures the percentage of people who click a link, ad, or other call-to-action out of everyone who sees it. It’s a direct indicator of how engaging and relevant your messaging is to your audience, whether that’s in email marketing campaigns, paid advertising, or organic search results. For example:
- In email marketing, CTR is the percentage of recipients who clicked a link in your email out of all who received it (excluding bounces).
- In paid ads/search, CTR is the percentage of people who clicked on your ad compared to the number of times it was shown.
- In organic search, CTR shows how many searchers clicked your link from a search engine results page.
CTR Isn’t a Vanity Metric – It’s Your Roadmap to Profitable Marketing
Having a high CTR percentage means that your message is resonating with your target audience and driving action. It’s a key metric for comparing campaign performance and identifying what works and what doesn’t. Platforms like Google Ads use CTR to determine ad quality and placement, which affects your ad costs and their visibility.
What Is The Click-Through Rate Formula?
Calculating CTR isn’t complicated, but getting it right is critical for making data-driven decisions that move your business forward. Here’s the click-through rate formula that will become your go-to measurement tool:
General Click-Through Rate Formula:
CTR (%) = (Clicks ÷ Impressions or Emails Delivered) × 100
Email Marketing Click-Through Rate Formula:
CTR (%) = (Unique Clicks ÷ Emails Delivered) × 100
Ads/Search Click-Through Rate Formula:
CTR (%) = (Clicks ÷ Impressions) × 100
Click-Through Rate Calculation – Step-by-Step
Let’s walk through the exact process so you can start measuring your performance today. Here’s how to calculate CTR for any channel:
- Count your clicks: Total number of times users clicked your link or ad.
- Find your impressions or emails delivered: Number of times your content was displayed (or emails delivered, not just sent).
- Apply the CTR formula: Divide clicks by impressions (or emails delivered), then multiply by 100.
Real Examples
| Channel | Clicks | Impressions/Delivered | Calculation | CTR |
| Paid Ad | 200 | 10,000 | (200 ÷ 10,000) × 100 | 2.0% |
| Email Campaign | 120 | 4,800 | (120 ÷ 4,800) × 100 | 2.5% |
| Organic Search | 398 | 1,000 | (398 ÷ 1,000) × 100 | 39.8% |
Unique Clicks vs. Total Clicks in Email Marketing
You’ve now mastered the core CTR formulas and calculations across various channels. But, when diving into your email marketing data, there’s a critical distinction that’s easy to overlook and can mess with your understanding of true engagement: the difference between unique vs. total clicks.
- With unique clicks, each recipient is counted once, no matter how many times they click. This is the standard for measuring email CTR.
- With total clicks, every click is counted, even if the same recipient clicks multiple times, which is useful for measuring total engagement, but it’s not standard for CTR calculation.
The preferred metric for campaign analysis here is unique clicks, as it provides a clearer picture of how many individuals are interacting with your content.
What Is a Good CTR Percentage?
CTR benchmarks vary significantly by industry and channel. To guide your goals and efforts, here are the most up-to-date 2025 averages:
| Channel | Average CTR (2025) |
| Google Search Ads | 6.66% |
| Google Display Ads | 0.46% |
| Organic Search (Pos 1) | 39.8-42.9% (With Snippet) |
| Email Campaigns | 2.00% (Range: 0.77-4.36%) |
| Social Media Ads | 1-2% (Range: 0.90-1.60%) |
While these provide a helpful glimpse into CTR, the best benchmark to use is your historical data. Consistently track your CTR over time with tools like Google Analytics, Google Ads Dashboard, or Email/Social Media Channel-specific tools, and aim for continuous improvement based on your unique campaigns and audience.
