Conversions represent desired actions users take, indicating engagement and progress towards business goals. "申请演示" (Request a demo), "提交销售线索" (Submit a lead), and "下载内容" (Download content) are all clear examples of conversions because they signify a user actively engaging with a business's offerings or content, moving further down the sales funnel. "网站浏览时间" (Website dwell time) can also be considered a conversion, especially in content marketing, as it indicates user engagement and interest, even if it's not a direct lead submission. "跳出率" (Bounce rate) is an engagement metric, but it's an indicator of disengagement, not a positive conversion action.
