Quick and easy way to calculate the conversion rate. Site conversion is the ratio of the number of users who performed a specific target action to the total number of its visitors. By learning your website’s conversion rate you can lower customer acquisition costs, increase revenue per visitor and leverage your business. If you have a high conversion rate, it means that you created a successful marketing strategy. For businesses to grow and expand, they need to monitor how their current efforts are performing, and where needed make changes. Conversion rate is calculated by taking Conversions/Visits x 100.
