If it's a vinyl sticker, using heat makes it more plyable. Helps when trying to apply on contours and uneven surfaces. For bigger stuff the pros also use a soap and water mix and spray it on the surface and stickers. Keeps the sticker from sticking. Once applied, they'll squeegee out all the water and air bubble nice and slow, starting from the middle and working their way out.
