The number of companies (big ones, public ones!) where I can't for the life of me figure out what they sell from their website is truly astonishing. I understand that 1) if I can't understand it I'm not in their market, and 2) they probably want to be vague so they can sell their prospects whatever they ask for [1] but I still feel that they could gain a lot in the long term through brand awareness and people like becoming or meeting their target customer (but not having had any idea what that company did) by making a clear articulation of what the hell they do.

[1] Funny story, I was at a market in India and asked a guy selling toys and things if he had any fireworks. He asked me a lot of questions about what I wanted, but I couldn't see any evidence of him having such a wide variety of stuff. Then he sprinted off and asked his neighbor vendor to watch his stall. He came back 5 minutes later with a ton of fireworks to my liking, I bought what I wanted and then he went back to the fireworks guy with his leftovers. I assume that in a split second he negotiated a deal with that guy where he borrowed the fireworks, sold me what he could, and took the rest back. I don't know what he marked me up but I hope it was a lot.
