Title: Conversion Rate Author: Kriko Published: Feb 9, 2021 Last modified: Jul 14, 2026 --- 1. [Home](https://kriko.io/) / 2. [Glossary](https://kriko.io/glossary) / 3. C Letter # Conversion Rate **Conversion Rate**, commonly abbreviated as CR, is a performance metric that shows the percentage of users who complete a target action on a website, application, advertising campaign or digital channel. To understand this metric, it is useful to first explain the concept of a conversion. A conversion is a specific action that a user completes and that is considered valuable for the business. This action can be a purchase, form submission, newsletter subscription, app download, quote request, phone call or account registration. A conversion does not only refer to actions that happen after an ad click. A user can convert after arriving from Google organic search, social media, an email campaign, direct traffic or a referral source. For this reason, conversion rate can be used both in advertising campaign analysis and general website performance analysis. The important point is to clearly define which action is accepted as a conversion. In e-commerce websites, the most common conversion example is a purchase. A user viewing a product, adding it to the cart, completing checkout steps and placing an order can be considered the main conversion in e-commerce. However, not every conversion has to be a sale. Add to cart, add to favourites, account creation, coupon usage, product review submission or store stock check can also be tracked as micro- conversions. These micro-conversions help understand how close the user is to making a purchase. The definition of conversion can vary across sectors. For a news website, a newsletter subscription may be a conversion. For a SaaS company, it may be a demo request. For an education institution, it may be an application form. For a healthcare provider, it may be an appointment request. For a finance company, it may be an account opening. For a mobile application, it may be an app install. Therefore, conversion rate should be interpreted according to each business’s own goals. The same rate can mean completely different things in different sectors or campaign types. Conversion rate is usually calculated as a percentage. The basic formula is: **Conversion Rate = Number of Conversions / Number of Visitors, Sessions or Clicks x 100**. The denominator changes depending on the analysis context. If overall website performance is being analysed, visitors or sessions can be used. If advertising campaign performance is being analysed, conversion rate can be calculated based on clicks. For this reason, the denominator used should always be stated when interpreting conversion rate. For example, if an ad was shown to 2,000 people, received 300 clicks and 60 of those clicks resulted in purchases, the post-click conversion rate would be 60 / 300 x 100 = 20%. This calculation shows the percentage of users who purchased after clicking the ad. However, if the goal is to calculate the impression-to-conversion rate, the result would be 60 / 2,000 x 100 = 3%. These two rates represent different things and should not be evaluated as the same metric. Conversion rate is highly important for understanding digital marketing and e-commerce performance. High traffic alone does not mean success. A website may receive many visitors, but if users do not purchase, submit forms or complete the target action, that traffic may not be efficient for the business. Conversion rate shows how much of the incoming traffic turns into a business outcome. Activities aimed at increasing conversion rate are called **Conversion Rate Optimization**, or CRO. CRO includes optimizations made to the website, landing page, form, checkout flow, content, offer and user experience so that users can complete the target action more easily. This process is not simply about changing the colour of a button. It requires understanding user behaviour, identifying friction points, running tests and making data-driven decisions. Many factors affect conversion rate on e-commerce websites. Page speed, mobile compatibility, product visuals, product descriptions, price information, stock status, shipping fee, payment options, trust elements, return policy and checkout simplicity are among these factors. For example, on a site that is not mobile-friendly, loads slowly or has errors during checkout, users may be less likely to complete their purchase. Therefore, technical performance and user experience directly affect conversion rate. On form-focused websites, form length, number of fields, amount of required information, error messages, trust explanations and CTA text can affect conversion rate. Asking users for too much information can reduce form completion rates. In contrast, a simpler, clearer and more trustworthy form structure can increase conversion rate. However, in some sectors, certain qualifying questions may be necessary to improve lead quality. Therefore, the goal should not only be to get more conversions, but also to generate higher-quality conversions. When analysing conversion rate, traffic source, device, location, new versus returning users, campaign type and landing page performance should be evaluated together. Users coming from organic search may not convert at the same rate as users coming from a remarketing campaign. Mobile and desktop users may also behave differently. For this reason, analysing conversion rate by segment produces healthier insights than looking only at the overall rate. Conversion rate is not a sufficient success indicator on its own. A high conversion rate does not always mean high profitability. For example, a very low-priced campaign may increase conversion rate but reduce profit margin. Similarly, a campaign with a low conversion rate may still be valuable if it generates high average order value or qualified leads. Therefore, conversion rate should be analysed together with metrics such as revenue, ROAS, CPA, CAC, average order value, lead quality and customer lifetime value. In summary, **conversion rate** is a core digital marketing metric that shows the percentage of users who complete the target action. It can be used for different goals such as purchases, form submissions, subscriptions, app downloads, phone calls or quote requests. For a healthy conversion rate analysis, the conversion definition should be clear, the correct denominator should be selected and results should be evaluated together with channel, device, audience and business goals. Increasing conversion rate is not only about bringing more traffic; it is about improving user experience and the conversion journey. ## Discover it in the dictionary ### Analytics Platform An analytics platform is an integrated technology solution that helps organisations collect, prepare, analyse and transform data from different sources into meaningful insights.
