Anyone can make one:
For better or worse, anyone can write a blog post about anything they want. Everyone has a voice and the best voices will rise to the top.
The writer can show their personality:
In blog posts, the writer has more leeway to add in their voice and personality than other types of writing.
Blogs are a great form of mass communication:
You can help people, learn new things, entertain your audience-the possibilities are endless and amazing. Blogging opens up all of these to a very wide audience.
You can make money:
Get the right blog going and you can make a lot of money through advertising and sponsored posts.
It allows people to craft better thoughts:
Instead of reading haphazard, uneducated Facebook statuses, it's much better to see people's thought process in a well-written blog post.
You can establish a community:
Blogging allows you to connect with other individuals who share the same interests. Sharing ideas and opinions within your community helps establish yourself as a thought leader.
Good for SEO:
Keeping content on your site fresh and relevant, you can use your blog to boost the search engine ranking (SEO) of your site and your business.
It brings people back to your site:
If your blog is strong enough and updated regularly, people will come back looking for more and bring traffic back to your site as well.
It costs you a grand total of zero dollars to post to the blog, so if you have something to say, there's nothing to stop you.
You can establish yourself as a thought leader:
A blog is a great place for your original thoughts, and it can be a wonderful way to show off your individuality. If people like your ideas, you can become a thought leader in your industry!
