I thought this infographic about LinkedIn was relevant so I decided to share it. It shows the balance of types of content you should have for your blog and while everything will vary for each person (just like every diet doesn't work for everyone). It is important to test and find a good mix that will work for you.
It is becoming more and more vital for entrepreneurs and business owners to blog. I wrote a post on Medium that addressed this idea “Why Your Business Should Be Blogging“. There's numerous reasons including SEO and Social Media but it is ultimately a way to communicate with your target audience.
If you are wondering what and when to blog. I thought this was a nice infographic, I borrowed from LinkedIn.
