Writing a blog post can either be for business or personal purposes, so how to write blog posts is going to be dependent on what the purpose is. The style in which you write will come into play. If yours is a personal blog, your style can be a stream-of-consciousness type as long as it flows well and is easy to read.
A blog post for business purposes is a little tighter. There are writing styles like Chicago and AP that you might want to adhere to depending on the potential clients you are aiming to influence. It might take a bit more work, but the potential pay-off, in the end, should make it worth your while.
In either case, writing on a blog, whether it’s yours or someone else’s, can be an enjoyable way to spend part of the day.
