HTTPS
为何重要
HTTPS encrypts the connection and is a confirmed Google ranking signal. Browsers mark plain HTTP pages as “Not secure”.
如何修复
- Install an SSL/TLS certificate (most hosts offer free Let’s Encrypt certificates).
- Serve every page over https:// and update internal links.
使用以下工具检查
- SSL Certificate Checker – Check an SSL/TLS certificate’s validity, expiry date, issuer, hostnames and protocol.
