How is Blog Popularity Measured?
Blogging is continuously gaining attractiveness and blog popularity can be measured in two ways: through citations and through affiliation. It was found in researches that permalinks require a shorter time to gain popularity than blogrolls. Furthermore, they give a better picture of popularity and authority. It is because they signify that visitors are actually reading the content of the blog and find it important.
The blogdex project by the MIT Media Lab was the first instantiation of a memetracker. Technorati measures blog popularity by giving rankings to blogs based on the number of incoming links while Alexa Internet does the same based on the web hits of Alexa Toolbar users.
