There are a few misconceptions people have that I can go over here, because I have also made these mistakes so far.
1.) Small chapters might help exposure, but most people don't like them. If it is under 1500 words then I find they all tend to lack details everywhere. While this might help you build up readers you will also hit a plateau much faster. Write what you want to write and set a schedule, if you only focus on getting readers then your story will have serious problems.
2.) Decide why you are doing this, if it is only an attempt to get famous then you are better off going elsewhere. If money is your goal then release straight to KU there is no point wasting time here. If you think that you produce something marketable then go straight to the source of money printing.
3.) When you release matters! I can not stress this enough. Yes, it is awesome to release when it is dead and you can get more exposure, but why is it slow? Has everyone become a reader? No, it means there is no traffic, the people are usually proportional. It is more important to get your post out even if it is only seen for 15 or 20 minutes on the front page. Spend time picking names for your chapters that sound appealing.
4.) Clickbait is a double-edged sword. It may seem nice to get lots of people reading your story and you might go to vast extremes to do so. Think about your limitations as a human, if you are new to this, you probably don't want a ton of exposure. First impressions are important, and if you link someone's name with something you hate then it is very likely you will ignore all of their future work. I read a book that was badly tagged and it was so upsetting to me I wanted to block the author. They used NTR everywhere and it wasn't tagged, that was fun.
