Landing faster than other players can give you a serious advantage early in the game. Getting to the ground faster means that you will (most likely) be the first player to collect the best weapons, items, and resources. You'll also get to find the best position -- helping you pick off the opposition all the more easily.
So how do you land faster than other players? Well, you could withhold releasing your glider for as long as you can. But the problem is that when you land, the game will make you use the auto-parachute feature as soon as you approach the freefall limit.
Fortunately, some players have found a glitch in the game that has allowed them to bypass Fortnite's auto-parachute activation by landing as close to the shoreline as possible.
So, as soon as the airbus approaches the island, jump right off at the shoreline and try to direct your freefall above the water just an inch or so away from the land. The auto-parachute system doesn't work above the body of water, so you will freefall as long as you need.
Then, you can manually release the glider just above the ground and get to gathering all the best loot you can get your hands on.
