下列何者是設定轉換追蹤的第一步？

The first step in setting up conversion tracking is to define what you want to track. This involves creating a conversion action within Google Ads, which represents a valuable customer interaction on your website or app, such as a purchase, lead form submission, or phone call. Once the conversion action is defined in Google Ads, you will then receive the necessary code or instructions to implement it. The other options describe subsequent steps or incorrect procedures. Requesting code from a webmaster or modifying code before defining the conversion action in Google Ads is premature. Modifying the conversion tracking code in Google Ads is not the initial step; the initial step is to define the conversion action itself.
