Blogs are useful for establishing your company or personal identity. If you're writing for business reasons, you can give clients and customers a feel for who you are. They can see a little bit of your expertise and get a glimpse of who your other clients are and where you go for reliable information. This is important because how you write and what you write about will give them a preview of your personality and work philosophies before they decide to contact you.
Now, some of you might be afraid that this could mean that you'll lose out on opportunities because some people might not contact you. To the contrary, the contacts that you do make from your blog will be more likely to be the ideal client. One that already likes your personality type and has a good feel for the services you can provide. And let's face it, these are the clients that will be the most profitable for you.
So remember that your blog is always a subtle marketing tool. Even if you don't expressly marketing your products and services in every post, you are always selling yourself. Don't be afraid to let your personality shine through and offer your opinions, recommendations, and experiences.
