I think you created the pricing schedule based on your costs. The more keywords being tracked the more "crawlers" necessary, meaning the more servers you need and thus more cost. Customers don't care about your costs, though. If I buy a first-class plane ticket to fly a can of Coke from Belize to Boise, it's still worth as much as a regular can of coke. They're pricing what they think their customers will value, especially what they think their richest customers will value. If you have a few thousand keywords, what you probably have is about a hundred 'stem'-ish keywords whose fluctuations will tell you 90% of what you need to know. If you're selling a ton of products, you will probably need more, but if you're doing that, why not track keywords at the category level (instead of "Aluminum Widget," "Cast Iron Widget," "Plastic Widget," just "Widget")?
