如想盡可能吸引更多網站訪客分享電子郵件地址，建議採用的策略是什麼？

Using Single Sign-On (SSO) tools like Google and Facebook Connect significantly increases email address sharing rates because it simplifies the process for users. Instead of manually typing their email and creating a new password, they can register or log in with just a few clicks using existing credentials. This reduces friction and perceived effort, making users more likely to share their email. Pop-up windows can be effective but are often intrusive and can annoy users, potentially driving them away. Placing email collection solely on checkout pages limits collection to only those ready to purchase, missing a large segment of initial visitors. Offering discounts via email is a retention strategy, not an acquisition strategy for collecting emails from website visitors.
