Writing a blog post does not mean you are adding unnecessary words and stretching out. A proper blog post tries to teach people, inform people, educate people and entertain people. If you want to learn how many people use internet, you can ask this question on google and get exact answer, but if you want to get more information such as internet users by countries, age group, etc. you will need a longer article. This is where a blog post come in. If your content is liked by search bots it will also be liked by humans
