The post that converted at the better rate had a link MeetingBurner in the first paragraph (above the fold, as we like to jargon-ize it).
People don't really read things online, they scan. some things jump out, and only if you're very intrigued will you actually read the individual words. In fact, very few of you will even get to this line that I'm writing. The chances that you'll read each line decreases exponentially.
Note that I've made all of my main points in the first sentences of what I've written. Did you even read everything, or did you just scan through and pick up on a few words? The attention paid to each line decreases exponentially as you continue.
