Have you ever read a random blog post that was shared by a friend on Facebook or Twitter? This is exactly why having a like/share link on your blog is very important. Blogs are incredible in the manner in which they allow you to grow an audience and share your knowledge on a subject. When your blog is being shared on different social networking sites, you are gaining free exposure in all different areas of the web. This helps a business gain brand exposure, which can lead to potential new clients. The beautiful part of this is that not all your blogs have to focus on just what your business is doing. You can post something of general interest, and still reach potential new customers. The more people who follow and share your blog the more leads you can develop for your business.
