For these reasons, over the past few months we’ve been running tests taking into account whether sites use secure, encrypted connections as a signal in our search ranking algorithms. We've seen positive results, so we're starting to use HTTPS as a ranking signal. For now it's only a very lightweight signal — affecting fewer than 1% of global queries, and carrying less weight than other signals such as high-quality content — while we give webmasters time to switch to HTTPS. But over time, we may decide to strengthen it, because we’d like to encourage all website owners to switch from HTTP to HTTPS to keep everyone safe on the web.

谁有好的方法 可以在不影响网站的性能或者影响很小的情况下，来给网站全站增加下https？？

**最後一段不是寫了嗎 ^^|

目前影響不到 1%, 但會慢慢加重 ^^|**

给IIS添加CA证书以支持https

对于安全性较高的网站，类似电商支付页面，支付宝内页等用带s的。
普通的资讯站，倒没必要考虑https。
但这个消息对做外贸B2C的是有帮助，会有不少人尝试申请https。
