Here are a few examples how to maximize your profit and efficiency on Steemit:
Daily Post Rate:
You should only post 4 times / day on Steemit. If you post more than 4 times, a new algorithm will kick in, and starts to tax any additional rewards you earn on the same day for posting. So better save your better ideas for another day to maximize profit.
Now there is an app that will show you how many posts you have left made by

But I'm afraid it has a little bit of bug, as if you post 4 posts a day, next day the timer won't reset, only after 48 hours, so make sure you know how many times you've posted, because this would waste you 1 day.
As a rule of thumb I think Steemit works on UTC time so you just have to post the next day starting with 00:00 hour UTC time after you've post the 4 posts the previous UTC day. So make sure you set your clocks to UTC time if you are going to be efficient here.
Less is More:
Try to post less articles with higher quality, than more articles with lower quality. I personally try to always come up with interesting topics, especially revolving around steemit and cryptocurrency. Definitely don't spam, and keep your topic clear.
People have lower attention spans, so you have to be efficient and use as little text as possible to explain as much information as possible. The `information/text` ratio has to be high.
No Boring Topics:
Nobody cares what your grandma bought yesterday from the grocery store. Choose a popular tag and post in that topic area. Choose a primary tag that your topic will be centered around, and add additional secondary topics to try to reach out to more topics. Your tags should not be offtopic as well.
Think like this: Do I want to read this topic if I were the audience? And if yes, then write about it, if no then skip it, and find something better.
