During some of my research, I came across some eye-opening statistics!

Blog Facts

1. 50 Million US Internet users visited blog sites in Q1 2005. That’s 30% of all US Internet Users and 1 in 6 of total US population. Source: ComScore

By extrapolating the data in #5 below, that number would now be (at a minimum) over 71 million Internet users visiting blogs.

2. 1 out of 20 US adults have created a blog and 11% of Internet users are regular blog readers. Source: Pew Internet & American Life Project Report

Using current data, that means almost 12 million people have created blogs and over 26 million read them.

3. In a survey of the attitudes toward blogs, 77% of the respondents thought the regularly updated journals were a useful way to get insights into the products and services they should buy. Source: BBC Report

Think of the power testimonials and recommendations have on your blog!

4. According to Technorati, currently there are 51.8 Million weblogs and the blogosphere continues to double about every 6 months.
