A conversion rate is the percentage of people who take a desired action after being exposed to an email marketing campaign or visiting a particular website. The desired action can be anything from buying a product or service to signing up for a subscription or registering for an event. Conversion rates are important because they give marketers a way to measure the effectiveness of their campaigns and determine which areas need improvement. There are a number of factors that can influence conversion rates, including the quality of the marketing message, the strength of the offer, and the timing of the campaign. Email marketing, in particular, often has high conversion rates because it allows marketers to build relationships with their subscribers and personalize their messages. By understanding conversion rates and how they work, marketers can create more effective campaigns that result in more sales and higher profits.
