Alignment may be the most important part of the pre-shot routine. Most amateurs I see set their feet first and this is a critical error. Pick a specific target and align the clubface to that target (or intermediate target if you use one). Then align feet and body using the clubface. This will also improve consistency in ball position and distance from ball issues in set-up. When you look back to your target, it may not look correct. That is normal and you just have to get used to that. Our eyes are on the side of the line and therefore give us a skewed perspective. The other mistake players make is that they don’t practice alignment or check it often so it doesn’t get off.
