Forrester Research conducted a census of European bloggers, of which there were only 4 million people . Basically, these are young people who are interested in new technologies and spend a lot of time on the web.
Although there are very few bloggers, these young and active people are a very attractive audience to show them advertising. The study showed that bloggers are different from average Internet users: they are more open and trust each other, which is ideal for marketers.
