Title: Click Through Rate (CTR) Author: Kriko Published: Apr 19, 2021 Last modified: Jul 11, 2026 --- 1. [Home](https://kriko.io/) / 2. [Glossary](https://kriko.io/glossary) / 3. C Letter # Click Through Rate **(CTR)** **Click Through Rate**, commonly abbreviated as CTR, is a digital marketing metric that shows the percentage of users who click an ad or link after seeing it. Its basic formula is **number of clicks / number of impressions**. The result is usually expressed as a percentage. CTR helps advertisers understand how effectively an ad attracts user attention. CTR can be explained with a simple example. If an ad receives 10,000 impressions and 850 users click on it, the CTR is calculated as 850 / 10,000. In this case, the click-through rate is 8.5%. An impression means that the ad was displayed to the user, while a click means that the user interacted with the ad and followed the related link. For this reason, impressions and clicks are separate metrics. A high CTR often indicates that the ad is attention-grabbing and reasonably relevant to the target audience. However, a high CTR does not always mean that the campaign is successful. If users click the ad but do not complete a purchase, submit a form, register or perform another desired action, the campaign may still fail to meet its business objective. CTR should therefore be evaluated together with conversion rate, cost per conversion, ROAS, revenue and lead quality. A low CTR may indicate that the ad is not attractive enough, the audience is not selected correctly or the message does not match user intent. The headline, description, image, offer, targeting, keyword selection or ad placement may need to be reviewed. However, a low CTR is not always negative. In some brand awareness campaigns, the primary objective may be reach and visibility rather than clicks. To improve CTR, ad copy should be clear, relevant and aligned with user intent. A strong value proposition in the headline, a helpful message in the description and an appropriate **CTA** can improve click-through performance. Phrases such as“ Get a Quote”, “Explore Now”, “View Details” or “Buy Now” can be used depending on the campaign objective. However, misleading or exaggerated CTAs may generate clicks in the short term while harming user experience and conversion quality. There is no single ideal CTR value that applies to every campaign. Platform, industry, campaign objective, ad format, audience and competition all affect the expected rate. Search ads often have higher CTRs than display ads because user intent is more explicit. Display ads, social media ads and video ads should be evaluated according to their own performance dynamics. Successful **CTR optimisation** should not focus only on generating more clicks. The real objective is to reach the right user with the right message and encourage the expected action after the click. For this reason, ad content, landing page experience, targeting, bidding strategy and user behaviour should be analysed together. When interpreted correctly, CTR helps measure ad relevance and optimise campaign performance more effectively. ## Discover it in the dictionary ### Storytelling Marketing Storytelling marketing is the use of storytelling techniques in brand communication to build a stronger connection with the target audience.
