2. Statistics – how well did R-bloggers do this year?

There are several matrices one can consider when evaluating the success of a website.  I’ll present a few of them here and will begin by talking about the visitors to the site.

This year, the site was visited by 2.7 million users, in 7 million sessions with 11.6 million pageviews. People have surfed the site from over 230 countries, with the greatest number of visitors coming from the United States (38%) and then followed by the United Kingdom (6.7%), Germany (5.5%), India( 5.1%), Canada (4%), France (2.9%), and other countries. 62% of the site’s visits came from returning users. R-bloggers has between 15,000 to 20,000 RSS/e-mail subscribers.

The site is aggregating posts from 569 bloggers, and there are over a hundred more which I will add in the next couple of months.

I had to upgrade the site’s server and software several times this year to manage the increase in load, and I believe that the site is now more stable than ever.

I gave an interview about R-bloggers in at useR!2014 which you might be interested in:

I am very happy to see that R-bloggers continues to succeed in offering a real service to the global R users community – thank you all for your generosity, professionalism, kindness, and love.
