Not all mobile ads are created equal; some are designed to direct users to a mobile web page, such as a landing page, a product page, or a checkout page. In this case, it's important to measure how many users complete a desired action on your mobile web page, such as filling out a form, subscribing to a newsletter, or buying a product. These actions are called mobile web conversions and they can help you assess the quality and relevance of your mobile web traffic. To do this, you need to measure metrics such as conversion rate (the percentage of users who complete a conversion on your mobile web page after seeing or clicking on your ad), click-to-conversion rate (the percentage of users who complete a conversion on your mobile web page after clicking on your ad), cost per conversion (the average amount you pay for each conversion generated by your ad campaign), and conversion value (the average revenue or profit generated by each conversion completed by your users). By measuring these metrics, you can optimize your mobile web page design and user experience, and test different mobile ad variations and strategies to increase your conversion rate and value.
