Virality is a metric that tells you how successful an article is in comparison with all the other articles from that same website.
Mediatoolkit is constantly tracking the number of average interactions on social media (Facebook and Twitter) of each article. Virality shows the extent to which this article is more successful than the average article that was published on that site.

For example, if an article from CNN.com in the first 10 minutes after its release has 10.000 likes/ shares/ tweets, and the average article from the same site has 1.000 interactions on social media, then the first article is 10 times more viral. Virality is a reliable metric because you can compare the social impact of mentions without worrying about the size and influence of a specific website.
