To blog or not to blog...that isn't the ONLY question. First let's address why you should blog.
It is a chance to share something with the world. There is only one unique you, with your knowledge, that can give words of wisdom to others. Think if it like a gift to your readers.
You get to develop your niche. If you hone your writing onto just a few things, it helps you refine your niche.
With your niche developed, the more you write, the more you become an expert. You might focus on divorce or dating. Either way, people will read your stuff because you know what you are talking about.
It is a way to connect with others and communicate about who you are and what you do. Blogging can be a great networking tool.
WAIT! What about SEO? Well...so glad you asked :) Your blog CAN help with your SEO. BUT, if your blog is seperate from your website, that is so very sad for you because your blog is doing very little for your website. Which means you have to work twice if not three times harder to get your SEO up there and looking stellar. Also, who wants to manage two accounts, two websites - UM, not me. So when you are choosing a platform for your website, you need to take this into consideration. This is why we really love platforms that have the blog integrated. Become an expert and show the world that you know what you are talking about- Blog!
