Put your butt on the yellow circle!
A common error is for folks to focus upon and aim for the centre of the “H” which leads to both a too shallow approach at at bottom and the tail being too far back.
Focus on the opposite side of the helideck. This should lead to an approach and hover with rotor mast of the helicopter being over the H.
Much better to be a bit too far forward when you can see what obstacles are ahead of you than too far back where you can’t see any obstacles.
On take off folks sometimes focus on a point just in front of the nose. As the helicopter lifts off the point starts to disappear under the nose and they instinctively back up to keep it in sight. Especially at night.
Just my crackpot opinion.
