Unfortunately, there is no real way of driving traffic to parked domains that will last.
This is because the users of the internet do not want to waste their time looping through endless advertisement. This worked back in the day (2000's).
That only way to get sustained traffic is through leaching off of popular websites. IE

LOL you will probably end up spelling it wrong! This is where parked domains cash in!
You would have to be trending very well to catch the future of websites to be big, then invest in misspells as long as they do not own a trademark on their domain.
