By a fluke I noticed that "mobile inventory management" and variants brought me tons and tons of clicks from AdWords for incredibly cheap.

Attempting to capitalize on that, I did my best to make the product "mobile ready" and started flinging some of the traffic at a special mobile landing page.

Having not converted any of that traffic, I've ascertained that they're probably looking for a native inventory app rather than a web app.

Edit: "tons and tons" is relative to the clicks I was getting before this discovery.
