阿奧是 FindYourHome.com 網站的行銷人。他認為網站速度緩慢會降低使用者的瀏覽意願，但不確定該如何向開發團隊和高階主管表明及證實自己的看法。 如要改善這個網站的效能，阿奧可透過哪一項工具測試、分析及回報建議事項？

測試我的網站" (Test My Site) is a Google tool specifically designed to analyze website speed and performance, providing actionable recommendations. This makes it ideal for Aao to demonstrate the impact of slow loading times and suggest improvements to his development team and executives. Site123 and Squarespace are website builders, not performance testing tools. Visual Studio is an integrated development environment (IDE) used for software development, not for analyzing website performance from an end-user perspective.
