Slight forward cyclic and a good rotor brake are your best bet, assuming open area. You want to minimise uncontrolled blade movement, i.e. the bouncing and banging stop-to-stop as it turns down. Moderate cyclic use after the engine will help, but at some point the rotor stops being a wing and goes random. One sweats bullets then. Aside from that... Avoid shutdowns on rooftop helipads (more below) and generally, in the lee of buildings. I say "generally" because if the structure is substantial enough that it blocks the wind sufficiently, I'd head for it's wind shadow as a first choice. The lee of a stand of trees helps too.. .ON the rooftop helipad option mentioned above, some considerations. If your flight is generally smooth and the the gusts are only obvious after landing, you could well improve your situation by landing at an elevated pad.
