There is quite a lot to learn from spammers when it comes to landing pages.
Check this one out: http://paleorecipebook.com/

The structure goes as follows:
#1 Hook
#2 Value (bullet points)
#3 More value (details)
#4 WOW! BONUS!
#5 OMG! More bonuses.
#6 Did I mention bonuses?
#7 Reviews
#8 More reviews. All these ppl can’t be wrong right?
#9 Buy button
#10 Security
#11 Buy button again

Notes:
– They don’t bother wasting precious below-the-fold space with the buy button.
– Content is king. Lots of work writing it all.
– Show the value. Be clever on how you articulate the value (top it off with “Bonuses”).

Bonus! (ha!)
