网站数据统计中pv、uv、统计统计华东网 源码ip的源码区别

       做网站，数据统计不可或缺。代码安装统计代码，统计统计可了解网站流量。源码

       网站流量统计中有PV、代码UV、统计统计IP三项数据。源码满仓股票指标源码新入门的代码SEO者，常混淆这三者的统计统计区别。接下来，源码我将解析它们。代码

       首先，ndk源码编译arm来了解三者定义：

       IP指独立IP数，小时内相同公网IP只算一次。

       PV是Page View缩写，即页面浏览量或点击量，每次刷新，解析播放地址源码PV计数。

       UV是Unique Visitor缩写，指访问网站的每台电脑客户端，:-:内相同客户端只计一次。

       明白了定义，主力监控的源码三者的区别清晰可见：

       IP统计的是某IP地址计算机访问网站次数，真实，衡量网站流量。

       PV反映浏览网站的页面数，每次刷新，PV增加。PV与来访者数量成正比，但不反映实际来访者数量。

       UV统计访问网站的电脑数量，通过浏览器缓存判断来访者身份。更换IP但不清除cookies，UV数不变。

       总结，IP与UV数据相似，IP反映网络地址数量，UV对应实际浏览者数量。统计局限于互联网，本地网站无法统计。
