How to write a blog post?

Before you start to write your first blog post, have a clear understanding of your target audience. What do they want to know about? What will resonate with them? This is where creating your buyer personas comes in handy. Consider what you know about your buyer personas and their interests while you’re coming up with a topic for your blog post. Then you’ll need a place to host this and every other blog post you write. This requires choosing a content management system (CMS) and a website domain hosting service. A CMS helps you create a website domain where you’ll actually publish your blog. Your own blog domain will look like this: http://www.yourblog.com. Now you need a sub domain which looks like blog.yourcompany.com.
Once you have your blog domain set up, customize the appearance of your blog to reflect the theme of the content you plan on creating. Before you even write anything, you need to pick a topic for your blog post. The next step — but not the last — is actually writing the content. Write about what you already know, and if necessary, do additional research to gather more information. 
After writing the editing process is an important part of blogging. Ask a grammar-conscious co-worker to copy, edit, and proofread your post. When you’re ready to check your formatting, make sure you choose a visually appealing and relevant image for your post.
No one likes an ugly blog post. And it’s not just pictures that make a post visually appealing — it’s the formatting and organization of the post, too.
