list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">使用内容分发网络（CDN）</span><p>：CDN将网站内容分发到全球多个节点，用户访问时可以从离自己最近的节点获取内容，减少网络延迟。例如，一个位于美国的用户访问一个使用了CDN的中国网站，CDN会将网站内容缓存到美国或附近的节点，用户可以从该节点快速加载内容。</p></li></ul><h3 style="box-sizing: border-box;

list-style: none; margin: 0px; scrollbar-width: none; font-weight: 600;">启用HTTPS协议</span><p>：SSL证书可以实现网站数据的加密传输，防止数据在传输过程中被窃取或篡改。搜索引擎也倾向于优先展示使用HTTPS协议的网站。例如，谷歌浏览器会对未使用HTTPS的网站标记为“不安全”，影响用户体验和信任度。</p></li><li><span style="box-sizing: border-box;
