BeaG's link is good.
1. Good product.

When thinking like a buyer, I would not use "calorimetry" to search for your item. I have no idea what that is. I would use hand knit headhand or hand knit earwarmer or any other similar combination.
You don't like lists but here is one that helped me and was very specific about fine tuning SEO:
