网站流量的统计是评价其推广的重要指标，也是分析网站推广及客户行为习惯的重要手段。
比较常用而且可靠的方式，是51LA，GOOGLE提供的相关统计工具。
功能比较多，只要植入相关代码就可以，比较容易实现。
植入ALEX排名工具条也是一种方式，据说有些网站互链时会关注这个指标。
实际上，ALEX排名只对大型门户网站有意义，对大多数网站只具一定的参考意义。
（评价网站还有PR，SOUGORANK等方式或指标）
如果需要对流量出具权威的评估，可以请类似艾瑞咨询公司的机构。
这种评估往往是为投资人或潜在的投资人准备的。
如果是出于网站自身的建设，需要请专业的顾问公司对网站流量的数据提供分析，并提供分析报告。
专业的流量分析报告有如下特点：
·完整性：对于网站访问量统计分析需要长期进行才能发现其规律，尤其对关系到网络营销策略和效果的有关因素进行完整的跟踪和分析更为重要，这些都需要对网站流量各项统计指标的含义有深刻认识，并制定完善的网站访问统计指标体系；
·规范性：网站流量统计指标很多，分析报告采用不同的分析指标体系得出的结论及其价值有很大不同，专业的网站流量统计分析报告对网络营销相关的信息进行规范的统计，这样才能从报告中看到具有说服力的数据；
·系统性：网络营销是一项长期工作，网络营销管理贯穿于网络营销活动的各个阶段，网站访问统计分析关系到网络营销整体策路以及各项活动对网络营销最终效果的影响，只有对网络营销管理具有深厚的理解才能发现众多相关因素之间的关系；
·指导性：一份完整的网站访问统计分析报告不仅可以清晰地看到网站运营的成就，并且可以从中发现网站访问与网络营销策略之间的关系，根据专业的分析建议采取针对性的网络营销策略，并进一步提升网络营销效果
统计流量可以知道是否有“机器人”在操作，也可以发现是否有DOS攻击
