Some of the best article writing advice I have ever read is to use this simple structure every time. It ensures you will provide a quality article every time.
Tell them what you're going to tell them. Then, tell them. Then tell them what you just told them. Make it easy. Writing in small form is as simple as using this structure every single time.
Introduction
Start with something to grab your reader's attention. Tell them what you are going to tell them. Give them a reason to stick around. Talk about the problem you have noticed, the effects of the problem, and then give them the solution. Don't be afraid to reveal too much in the introduction. They will keep reading if you are concise and to the point. They will want to hear what you have to say!
Body
Now tell them. In the body, you are just adding onto each point. Start with the problem and give 3 details backing up your claim. Then extend on the effects of the problem. Drive home your point about why the reader should care. Then give your reader a solution. Tell them why they need to do what you tell them. Try to give 3 supporting claims for everything you addressed in the introduction. The reader wants more.
Conclusion
The conclusion is the most important section. Tell the reader what you just told them. Give the reader a key takeaway. Then add more information from your other sections to remind them about what they just read.
