The average number of people who read blogs in 2008 was just under 50%. This number jumped another 10 percent by 2013 and the number of people blogging has also increased 5 percent in those same years. These levels are set to double over the next few years, so a better question is why are you not blogging already?
Google loves new content, and blogs are easy and fresh ways of publishing that content. A blog can be created in the time it took you to have a boring meeting about your company’s parking policies (which no one really cares about) or the 20 minutes you spent talking about the stock market with your water cooler buddy (which neither one of you really knows anything about). Google bots or spiders rank active websites higher than static websites. Meaning, websites that are creating new content, by default, are making the site active since people who read the blogs will also comment. Those comments create interaction between the company and the buyer.
