To get higher ollies, I would suggesting resting your back foot on the very end of the tail and the front foot in the middle of the deck to allow for more slide. Popping as hard as you can and catching your board in the groove of the nose with you ankle practically resting in the groove will level the board out in the air. after this initial movement slide you feet back to the bolts on the tail and nose to ensure a clean landing.

The following descriptions cover skateboard parts that are most prevalent in popular and modern forms of skateboarding. Many parts exist with exotic or alternative constructions. A traditional complete skateboard consists of the deck (often with griptape applied on top to enhance traction), trucks (with urethane bushings), wheels (with sealed bearings), bushings, nuts and bolts to fasten the truck and wheel assembly to the bottom of the deck. Older decks also included plastic parts such as side, tail, and nose guards.

There are actually several types of skateboards but the most common ones are the longboard, cruiser, and carve skateboards. A longboard is usually at least 33 inches. It is a great mode of transportation and works well for cruising around. The cruiser also works well as a mode of transportation but many consider it more beneficial as it has a shorter skateboard, which promotes ease in transporting around.
Any serious skateboarder will tell you that the ollie is the most fundamental skateboard trick. In fact, it's probably the first trick that you'll learn on your skateboard. They’re great for getting over obstacles, moving around on your board, or just looking cool. Know the right way to move your feet on the board and with a little bit of practice, you can learn to pull off the perfect ollie.
Slam your back foot down on the tail of your skateboard as hard as you can. At that moment, you want to also jump into the air, off of your back foot. This part is key and takes practice. The trick is in getting your timing right. You want to slap the skateboard’s tail down, and as it hits the ground, jump off of that foot into the air. Make sure to pull that back foot high into the air. It's a quick, snapping motion.
Today, many riders use the “ollie-pop” on more than just the flat-level surfaces in between other tricks, it’s used heavily in the half-pipe and bowl ramps to allow the rider to go even higher in the air. Performing the “ollie-pop” while you’re at or near the top of the lip is a great way to get an extra couple feet, which might be all you need to get that extra turn in and nail the 720 (or 900, if you’re Tony Hawk).
GREAT board. Great design graphics. The boards deck has a real POP to it that makes it GREAT for tricks and a AWESOME beginner board. Only problem is It's super slow and requires a lot of work to maintain speed or to pick up speed period. A simple $20 wheel barring upgrade will fix that and BOOM PERFECT board, PERFECT caved in deck. Only 4 stars because of the lack of speed. I prefer my boards ready out of the box already pre-upgraded, but for the price, no point in complaining. Like almost all new boards, u have to ajust the wheels and the flex of the board to customize it to your liking. You won't regret it. But order it with some "Lucky" or "Red bearings" and your set.
