R-bloggers.com is now two years young. The site is an (unofficial) online R journal written by bloggers who agreed to contribute their R articles to the site.

In this post I wish to celebrate R-bloggers’ second birthmounth by sharing with you:

- Links to the top 20 posts of 2011
- Statistics on “how well” R-bloggers did this year
- An invitation for sponsors/supporters to help keep the site alive

### 1. Top 24 R posts of 2011

R-bloggers’ success is largely owed to the content submitted by the R bloggers themselves. The R community currently has almost **300 active R bloggers** (links to the blogs are clearly visible in the right navigation bar on the R-bloggers homepage). In the past year, these bloggers wrote over 2800 posts about R.

Here is a **list of the top visited posts** on the site in 2011:

### 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** over 665,000 “Unique Visitors.” There was a total of over 1.4 million visits and over 2.8 million page-views. People have surfed the site from over 200 countries, with the greatest number of visitors coming from the United States (~40%) and then followed by the United Kingdom (6.9%), Germany (6.6%), Canada (4.7%), France (3.3%), and other countries.

The site has received between 15,000 to 45,000 visits a week in the past few months, and I suspect this number will remain stable in the next few months (unless something very interesting will happen).

I believe this number will stay constant thanks to visitors’ loyalty: 55% of the site’s visits came from returning users.

Another indicator of reader loyalty is the number of subscribers to R-bloggers as counted by feedburner, which includes both RSS readers and e-mail subscribers. The range of subscribers is estimated to be between 5600 to 5900.

Thus, I am very happy to see that R-bloggers continues to succeed in offering a real service to the global R users community.

### 3. Invitation to sponsor/advertise on R-bloggers

This year I was sadly accused by google adsense of click fraud (which I did not do, but have no way of proving my innocence). Therefor, I am no longer able to use google adsense to sustain R-bloggers high monthly bills, and I turned to rely on direct sponsoring of R-bloggers.

**If you are interested in sponsoring/placing-ads/supporting R-bloggers, then you are welcome to contact me.**

Happy new year!

Yours,
