New Research and Visualizations About Who Links to Wikipedia

From the Wikimedia Blog:

To learn more about who links to Wikipedia, our research team at the University of Sheffield analyzed the structure of links that point to Wikipedia pages from external websites, looking specifically at which top-level domains dominate the link volume for each Wikipedia language. Here’s what we found.
Key Findings

• The main top-level domains that link to the English Wikipedia are: .com, .org, .blogspot.com, .net, .edu, and .co.uk.

• The most popular Wikipedia according to the number of links that it receives from external websites is the English Wikipedia. After that, the Spanish, the Indonesian, and the German Wikipedias are the most popular.

• Websites under blogspot.com contribute many links to Wikipedia. For the Spanish, Indonesian, and Portuguese Wikipedias they contribute more than all the other .com websites.

• Out of the 36 million links to Wikipedia, 18 million links are from .com domains to the English Wikipedia.

• Most links to the German and French Wikipedias come from .de and .fr domains respectively.
