If I was going to give any advice for landing pages, I would say "don't make it cheesy or over the top". I hate gimmicky stuff and you're not getting me any further if you don't communicate what I'm here for.

Also, if you don't put a price up front, I'll be ticked if it doesn't correlate to how much I would believe an offer is worth. I've read through countless landing pages that promote some service and then right at the bottom after the marketing pitch it says "only for $30!" ... whoa, what? Pffffff. I might have taken it if it was ten bucks.
