I've been doing some research into text input placeholders, and came across this: Pardot User Guide: Placeholders are not Substitutes for Labels.
What struck my interest was:

My question; is there an effective method of using placeholders to reduce the possibility of confusion that the placeholder text is some kind of auto-filled input?
Personally, I would suggest the
ex. John since it has the highest contrast to an actual input.
