The blog authors want to know the ranking of their blogs. Relations between page views and rankings were released by some questionnaires. However, there is no guarantee that the data of the questionnaires are correct. Furthermore, the results of each questionnaire differ mutually.
Since the main point which rectifies distortion of the data as a result of a questionnaire was found as a result of considering the correct relation between page views and ranking, the compensation method was proposed. Furthermore, the relation between the correct page views and ranking using the compensation method was obtained.
The actual relationship between page views and blog ranking is as follows.
1（PV／day）, Top 51％ ＝ Bottom 49％。
10（PV／day）, Top 18％
100（PV／day）, Top 6％
1,000（PV／day）, Top 2.2%
10,000（PV／day）, Top 0.8%
3. Data used for analysis
Three data are used for analysis as follows.
a) "SOTB 2009"
Questionnaire data by Technorati, State of the Blogosphere 2009
Data source, http://technorati.com/social-media/feature/state-of-the-blogosphere-2009/
b) "LMRB 2010"
Questionnaire data by Life media research bank in 2010
Data source, http://research.lifemedia.jp/2010/09/100929blog.html
c) "FC2 Blog I/E"
Survey data of relationship between Access ranking in "Idol/Entertainment" category of FC2 blog and page views measured by "FC2 access analysis"
Data source, former "Allez! Nogizaka 46" in "FC2 blog"
Three data mentioned above are plotted on fig. 1.
fig. 1 Relation of three data on double logarithmic chart
The page views (=the values of the X-axis) on the intersections of approximation lines and the y-axis of 100% should be zero mostly.This is because the page views of top 100% blog (=tail end blog) must be very small. Both of data of "SOTB 2009" and "LMRB 2010" means that the lowest page views of top 100% blogs (=tail end blogs) are 20 to 50 page views a day. Therefore, data of "SOTB 2009" and "LMRB 2010" are not correct.
On the other hand, "FC2 Blog I/E" means that the lowest page views of top 100% blogs (=tail end blogs) are 0.4 page views a day. Therefore, probably data of "FC2 Blog I/E" is correct.
"SOTB 2009" can be corrected the relationship between page views and ranking. Since "SOTB 2009" does not only grasp the number of the blogs of a small page views, "SOTB 2009" is not correct. Therefore, "SOTB 2009" is correctable (see fig. 2).
fig. 2 Corrected "SOTB 2009"
"LMRB 2010" can not be corrected the relationship between page views and ranking. The inclination of the approximation line of "LMRB 2010" differs from other two data. Therefore, it seems that "LMRB 2010" contains two or more errors.

However, I wrote it in Japanese suitable for machine translation to other languages. Therefore, the text will be translated into your mother tongue if you click the translation "powered by Google" button on that page.
However, since the machine translation "powered by Google" has very low capability, I do not recommend it to you. I would like to recommend you to use another translation engine.
6. Method to compensate questionnaire data
- Do not use the answers whose page views are less than 30 (PV/day) because of low accuracy.
- Adjust ranking so that the page views of the blog of top 100% ranking (=tail end blog) may become an appropriate value (less than 1 PV/day).
- Verify the inclination of the approximation line in a double logarithmic chart whether it is an appropriate numerical value.

Japanese people have long history about the girls' idol group. The groups of the women in the 12th century who sing and dance were recorded on "The Tale of the Heike", and were called "Shirabyoshi." The "Kabuki dance" of the girls' group which "Izumo-no-Okuni" created was in fashion in the 16th century in Japan. Then, since the Japanese girls' idol groups have been cultured purely for the domestic market, they are maintaining the style unique till today.
Nogizaka 46 is the girls' idol group of such a style. Furthermore, the great portion of Japanese thinks that Nogizaka 46 is most beautiful girls' idol group in Japan. At least I think so.
