小简是 GlobalMovers.com 的营销者。在对自家网站和竞争对手网站进行比较分析后，她相信改善网站的速度和响应能力可提高成效和收入。 她应使用哪些统计信息来说服 GlobalMovers.com 的高管层优先改善网站速度？

Conversion rate is the most compelling statistic because it directly links website performance to revenue. A higher conversion rate means more visitors complete desired actions, like making a purchase or signing up, which directly impacts the company's bottom line. While average daily visitors and average page views indicate site traffic and engagement, they don't directly measure business success. Click-through rate (CTR) is relevant for ads or internal links but doesn't capture overall website effectiveness in driving conversions. By demonstrating how improved site speed can boost conversion rates, Xiaojian can effectively persuade executives to prioritize this improvement.
