查询alexa网站排名历史数据的方法

通过情况下我们只看到alexa提供的图表显示网站排名,有时候需要研究对手网站的历史数据,就需要查询alexa历史数据,但从哪里查询呢??现在有答案了,就是使用amazon提供的AWS服务,而且必需使用程序才能查询哦,可以是任意一种支持http请求和解释返回xml的语言,例如c#, js, delphi, c…

步骤:

  1. 登录到http://aws.amazon.com/awis
  2. 点击“Sign up for AWIS”按钮进入注册或登录启用服务(我在这里卡壳了,mastercard和visa卡都不在身边,又不能使用paypal,晚些时间才能注册了)
  3. 打开http://aws.amazon.com/code/AWIS下载一个例子代码
  4. 使用你从AWS获得的Access Key 和 Secret Key 替换例子里面的
  5. 按你需要修改例子里面的代码

如果顺利,你应该可以查询到数据了,例子发出一下像下面的请求URL

http://awis.amazonaws.com?&AWSAccessKeyId=YOUR_ACCESS_KEY_ID&Action=TrafficHistory&ResponseGroup=History&Timestamp=2011-06-08T21%3A13%3A01.000Z&Signature=1%2FuvM9a0pjGm5j9tSDW6S5G9q%2Bk%3D&Start=20110101&Range=30&Url=somesite.com

它会返回像下面XML的内容

<?xml version=”1.0″?>
<aws:TrafficHistoryResponse xmlns:aws=”http://alexa.amazonaws.com/doc/2005-10-05/“>
<aws:Response xmlns:aws=”http://awis.amazonaws.com/doc/2005-07-11“>
<aws:OperationRequest>
<aws:RequestId>2f7207ba-9109-d5a9-92d3-38299b896f4c</aws:RequestId>
</aws:OperationRequest>
<aws:TrafficHistoryResult>
<aws:Alexa>
<aws:TrafficHistory>
<aws:Range>30</aws:Range>
<aws:Site>somesite.com</aws:Site>
<aws:Start>2011-01-01</aws:Start>
<aws:HistoricalData>
<aws:Data>
<aws:Date>2011-01-01</aws:Date>
<aws:PageViews>
<aws:PerMillion>45.6</aws:PerMillion>
<aws:PerUser>9.0</aws:PerUser>
</aws:PageViews>
<aws:Rank>2307</aws:Rank>
<aws:Reach>
<aws:PerMillion>480</aws:PerMillion>
</aws:Reach>
</aws:Data> 

简单吧,每一个查询都需要钱的哦, 每一次请求$0.00015 美元 (即1000个请求$0.15美元)

对于需要研究历史数据的人来说这个值得的

alexa数据预估流量太不准确了alexa data estimate the flow rate is too inaccurate

有些客户都不了解自己究竟要什么数据,例如前段时间碰到个一上来就跟我说,

要使alexa数据预估流量的ip流量提升到10万,

我说在alexa官方网站没有预估流量的,其它统计网站提供的预计流量是通过自己的特定算法计算出来的,

例如爱站上的综合查询会显示网站的alexa世界排名和预估流量,这个是它自己预估的,

alexa数据预估流量

我可以提升alexa排名,但无法修改别人的算法阿,然后我找几个自己的站比较一下,没有发现

它这个数据有没有什么比例之类的,可能引入的变量比较多,所以不能简单的比较出来

但有一点可以确认的是,alexa排名越高它计算的预估流量就越大。然后我想到反过来比较应该也一样的,

我找了一个预估流量在10万左右的网站,看看它的alexa排名,然后将这个排名的报价给他

他又说要ip流量什么的,真浪费时间阿,都不知道自己要什么来滴,阿米陀佛!Some customers do not understand exactly what data, for example, met one up some time ago told me that,

For the alexa data flow ip traffic is forecast to increase to 10 million,

I said in the alexa official website did not estimate the flow, and other statistical sites is expected to flow out through their own specific algorithm.

Comprehensive inquiry on the station will show the site such as love alexa world rankings and forecast traffic, this is its own estimate of

alexa数据预估流量

I can improve alexa ranking, but can not modify someone else’s algorithm A, and then I find a few own the station compare and found no

Its data what proportion of the class, may introduce the variable, it is not a simple comparison of out

But can confirm that, alexa rank higher the greater it calculates the estimated flow. Then I thought that in turn should be relatively the same,

I find the site of an estimated flow of about 100 000 to see if it’s alexa ranking, this ranking offer to give him

He also said to be the ip flow what really a waste of time, O do not know what they want to drop, Ami Tuo Buddha!
