Calculate more accurate number of pageviews of any website

Today I found that, we can calculate more accurate number of pageviews and unique visitors of any website just using Alexa traffic stats. 

In Alexa stats we can only know about estimated percentage of global page views of a website. That means if we deter the global page views number then, we can easily calculate page view number of any website.


Global page-view: According Wikimedia traffic analysis report for the period of 1st Apr 2011 -31st March 2012 says that monthly page views of English Wikipedia is 11630 million (11630000000). 

But Alexa global page views percentage of www.wikipedia.org is 0.4796 (monthly), 0.4934 (3 month). 

Change of percentage in three month is (0.0934-0.0796)=0.0138. 

So the change of percentage in one month-0.0138/3=0.0046. 

So, accurate percentage of monthly page views is (0.4796+0.0046)=0.4842, or  (0.4934-0046)=0.4888 

that mean nearly-0.4860.

Actual calculation is- Global page view=(100/0.4860)*11630000000 = 2,393,004,115,226 (apx).

Now we have global page views per month is 2,393,004,115,226.

Let's try to calculate TechCrunch.com recently monthly page view-

Alexa global page views percentage- 1 month-0.00772%. Last 3 month-0.00697%.  

Change in percentage in three month-(0.00772-0.00697)=0.00075

Average change-0.00075/3=0.00025

Actual average percentage of global monthly page views is- 

(0.00697+0.00025)=0.00722 or (0.00772-0.00025)=0.00747

Comparing tow results we get -0.00735% (actual result of Alexa monthly page view percentage)

So, actual average monthly page views of TechCrunch.com is (0.00735*global page view)/100

=(0.00735*2393004115226)/100

=175885802.469

Average unique visitor: According Alexa in three month average unique pageviews per user is nearly 2.035

Therefore, Unique visitor of TechCrunch.com is =(total page view per month/ average unique page view per user)

= 175885802.469/2.035

=86430369.76  

Formula-

1. Find out one month and three month page views percentage from Alexa.
2. Calculate the average change of page view percentage in three month. Follow the calculation above.
3. For actual monthly page views, add the result with one month percentage and subtracts the same result from three month percentage. Then take the average result.
4. Now put your result in this formula =(actual monthly page views (%)* 2,393,004,115,226)/100  

In this way you can calculate any website page views..
