One thing I noticed about your page is that its SEO optimized -- with the "Bingo Card" keyword to be exact -- rather than being user friendly. I think this is also another dilemma we are facing. We can put nice graphics with less text to our landing pages which will be very user friendly but it would also suffer lower SERP because of low keyword recurrence.
Kinda tangential, but since I want to help people do better at SEO: That page is not SEO optimized -- it isn't even designed to be accessible to crawlers. It is only linked to from post-purchase emails and me when answering customer support requests. No page on my site other than the front page would ever rank for [bingo cards], certainly not on the strength of on-page optimizations.
If a consulting client told me they were worried about poor rankings because of low keyword recurrence on their landing pages I'd tell them that on-page factors wouldn't make a difference for head-of-the-distribution terms either way and you don't need re-occurrence to rank for tail terms, so that is probably not a terribly big worry. Having insufficient text on a page to rank for anything is a bit of a worry. If you're trying to satisfy the competing imperatives "Conversion rate/user happiness goes up when we take text off" and "Rankings go up when we add text" the solution I'd recommend pretty quickly is "Put the text below the fold, where only Googlebot and the sliver of humans who actually enjoy reading will see it."
