</p> <p style="vertical-align:top;"> 2)HTTPS协议是由SSL+HTTP协议构建的可进行加密传输、身份认证的网络协议,要比http协议安全,可防止数据在传输过程中不被窃取、改变,确保数据的完整性? </p> <p style="vertical-align:top;"> 3)HTTPS是现行架构下最安全的解决方案,虽然不是绝对安全,但它大幅增加了中间人攻击的成本? </p> </blockquote> <p style="vertical-align:top;"> 建议?</p> <p style="vertical-align:top;"> 在成本费用允许情况下,还是建议站长采用HTTPS加密协议,毕竟网站安全也是用户体验的一个重要环节,而且还有利于搜索引擎排名,何乐而不为呢?</p> <p style="vertical-align:top;"> 使用HTTPS协议有何挑战?</p> <p style="vertical-align:top;"> 1、容易忽略的问题 </p> <p style="vertical-align:top;"> 将站点由HTTP转为HTTPS协议涉及到很多问题,有时候会忽略了一些重要的细节问题?</p> <p style="vertical-align:top;"> 1)robots.txt文件中是否屏蔽了重要的URL链接?</p> <p style="vertical-align:top;"> 2)Canonical标签指向的URL是否正确?</p> <p style="vertical-align:top;"> 3)当用户访问你的网站时,是否会出现浏览器安全警告提示窗口?(出现安全警告提示可能会吓走用户) </p> <p style="vertical-align:top;"> 虽然概率很小,但这几个问题还是可能出现的?</p> <p style="vertical-align:top;"> 2、网站加载速度问题 </p> <p style="vertical-align:top;"> HTTPS协议的握手过程比较费时,对网站的响应速度有负面影响。据ACM CoNEXT数据显示,使用HTTPS协议很可能会使页面的加载时间延长?0%。而网站加载速度也是影响搜索引擎排名的一个很重要的因素?</p> <p style="vertical-align:top;"> 不过,还是可以通过一些技巧来减少这个问题的。比如,压缩文本内容可以降低解码耗用的CPU资源。实际上,建立HTTPS连接,要求额外的TCP往返,因此会新增一些发送和接收的字节,但这是打开网页时的情况?</p> <p style="vertical-align:top;"> 3、成?</p> <p style="vertical-align:top;"> 据数据显示,很多站长每年花在SSL证书上的费用?00美元-200美元之间,这对于个人博客、或是小型站点来说是一笔不小的开支。不过,现在网上也有不少免费SSL证书?</p> <p style="vertical-align:top;"> 4、HTTPS兼容性问?</p> <p style="vertical-align:top;"> 这里所说得“兼容性”包括很多方面,比如现有的Web应用要尽可能无缝地迁移到HTTPS、浏览器对HTTPS的兼容性问题、HTTPS协议解析以及SSL证书管理等?</p> <p style="vertical-align:top;"> 5、更多问?</p> <p style="vertical-align:top;"> 如果你的网站依靠AdSense获得收入的话,那么转型HTTPS站点可能会使得收入大幅下降(谷歌对广告源采用SSL协议的站点有所限制)?</p> <p style="vertical-align:top;"> 此外,即使是谷歌管理员工具也尚不支持HTTPS站点的迁移工作。要完成SSL加密的全球化,需要的不止是时间,还少不了各方的努力啊?</p> <p style="vertical-align:top;"> 使用HTTPS协议的站点数量增长情?</p> <p style="vertical-align:top;"> 如今,越来越多的站点采用了HTTPS协议,不过大多用于登陆页面、或是存在交易信息的页面,很少网站选择全站采用HTTPS协议?</p> <p style="vertical-align:top;"> 据Builtwith调查数据显示,在排名TOP 10000的网站中,只?.2%的站点默认使用HTTPS加密访问模式。再将范围放大到TOP 100万个网站,这个百分比则降到了1.9%?</p> <p style="vertical-align:top;"> <br /> </p> <p style="vertical-align:top;"> HTTPS站点的SEO自检清单 </p> <blockquote style="vertical-align:top;"> <p style="vertical-align:top;"> 1、确保网站的每个元素(包括插件、JS、CSS文件、图片、内容分发网站等)都采用HTTPS协议? </p> <p style="vertical-align:top;"> 2、使?01重定向将HTTP URL指向HTTPS版地址。记住别误用302跳转? </p> <p style="vertical-align:top;"> 3、保证Canonical标签指向HTTPS版URL? </p> <p style="vertical-align:top;"> 4、采用HTTPS协议后,应确保网站内链指向的是HTTPS版URL,而非旧版URL。这对用户体验以及网站优化而言,都是一个很重要的步骤? </p> <p style="vertical-align:top;"> 5、在谷歌、必应等平台上的管理员工具中监控HTTPS版本站点? </p> <p style="vertical-align:top;"> 6、使用谷歌管理员工具中Fetch&Render功能(http://googlewebmastercentral.blogspot.com/2014/05/rendering-pages-with-fetch-as-google.html),确保你的HTTPS站点能够正常的被谷歌抓取? </p> <p style="vertical-align:top;"> 7、更新网站sitemaps,并在谷歌管理员工具中提交新版sitemaps? </p> <p style="vertical-align:top;"> 8、更新robots.txt文件,加入新版sitemaps内容,确保重要的HTTPS版页面不会被屏蔽? </p> <p style="vertical-align:top;"> 9、如有必要,还应该更新网站的分析跟踪代码。现在已经有很多新的谷歌分析代码段都能够处理HTTPS站点了? </p> <p style="vertical-align:top;"> 10、采用HSTS协议(HTTP严格传输安全协议),其作用是强制客户端(如浏览器)使用HTTPS与服务器建立连接。可在保证安全性的前提下,提高网站的响应速度? </p> </blockquote> </div> <div class="clear"> </div> </div> <br> <div class="tag">相关标签?/div> <div class="newbtn"> <div style="line-height: 30px;"><div>上一?<a href="8.html">智能冰箱线路板制作步?/a></div> <div>下一?<a href="6.html">科技进步给工人带来失业恐惧?</a></div> </div> <span class="newbtn2"><a href="/supply/"><img alt="" src="/template/yh/img/teshu.png">返回列表</a></span> </div> <div class="cp tjcps"> <h2> 相关产品</h2> <div id="cntrRelevantProd"> <div id="cptab_relevant"> <dl> <dt> <a rel="nofollow" href="/supply/91.html" title="车载线路?车载功放PCB?> <img src="http://cmsimgshow.zhuchao.cc/34321/201902221044065263432175786.png?path=www.atelierdu.com/uploads/cp/201902221044065263432175786.png" title="车载线路?车载功放PCB?
