Someone asked if I'm using blogging as some sort of marketing strategy. The simple answer is yes. In fact, if you remember the picture below from REWORK, everything you do is marketing.
You might be blogging to talk about your personal life, to share your passion or to improve your writing skills. Whatever the reason may be, since your blog is public, you are directly or indirectly marketing yourself.
This is true for the other online presence you have like Twitter and Facebook. Marketing isn't just about the product. It's also about who made it, why it was made and how it was made.
I'll encourage everyone to start a blog because it's really free marketing. However, you need to realize that everything you post on it will affect not just your personal life but your professional life too. When it comes to marketing, everything matters.
