The reliable method is to run many small experiments, commit fully to whatever works, and keep at it until it stops working.

Try a number of things, right? So, experiment with a number of things. Run a number of small experiments. Once you find something that works, double down on it and then keep doing it until it stops working, which is the step that a lot of people skip. Um, and then once it stops working, go back to the start and try a lot of small experiments again.
