I'm probably just being hard on myself. I've seen some pretty shitty LP's that convert. I just got to get this sucker finished and throw some traffic at it. I like that site, soem nice information on there. If it makes any difference, It's a blog style LP that I'm working on.
The main takeaway from that site is that there are two types of elements on page: things that help conversion and things that don't. You want to remove all the latter so there's no "unsupervised thinking." You want to answer 1) "Where am I?" 2) "What can I do here?" and 3) "Why should I do it?"
Sometimes 1) isn't as important, but 2) and especially 3) are absolutely necessary. Sounds like common sense, but simple methods beat the shit out of no framework anyday.
As to tools, I'm not really aware of free keyword tools. I mean, I've played around with Google's tools, but I'm not aware of anything else.
SEObook has a weak version of Wordtracker. It's not bad.
