Content is another word for article, write up or post. I would define King here as something that has a preeminent position. What am I trying to say? Your content should exceed others in quality and rank here. I am not saying you must be the best but I am saying you should strive to make your content king here. Your reason for joining this platform was to become a better writer while earning. If everyone should make their contents king, this platform will be filled with quality writers only.
What do you have to do to make your content king? Here are a few of them.
Be sure of your post type, don't just bring up random stuff and share for your audiences to read. Think of what will go through your audience, something positive, educative and full of inspiration. Don't focus on some communities, try out new ones so you could have different content type.
Do not let your audience get used to one style of post on your profile, it would become boring for them to visit your posts. Always change your style of write ups like for instance if you have been writing short posts, try out longer ones to keep your audience waiting for your next article. Be more creative with your header image or gifs so as to attract people to your content. Arrange your content beautifully to lure your readers to read till the end.
Having followed those steps above, now your content should be amazing and full of creativity. Your audience would want to see more of that, be consistent in giving such out. Make them always look forward to your next article, and give them consistent digest able contents.
Remember your content is king so it must be presented attractively, creatively and consistently. Also know that good contents present your profile for valuable leads. Your contents should be presentable for who ever visits your profile.
