I just read Suzanne Falter-Barns’ post on ProBlogger: Have Blogs Killed Conventional Websites? and I’d like to put in my 2 cents.
Used to be everyone was struggling to keep up with competitors just by having a website. Now if you don’t have a business blog you’re behind. Forget for a moment that you’re not web-savvy, if that’s true, and look at the benefits of blogs over websites. I’ll borrow from Suzanne’s list and add my own.
–Blogs are easier to update. Sites like WordPress make it simple to upload posts instantly, so as soon as you think of a topic, you can write it and post it within minutes. With websites, you likely have to call your IT or web design guy to get anything changed.
