Etsy Pounce is an under appreciated Etsy tool - and one that is built in. I used it a lot when I was researching opening a shop to see what people were actually buying. What I noted is that most of the sales were sewing/crafting supplies (hence me starting to sell fabrics).
Yesterday I mentioned the heartomatic, but didn't link to the real deal. Hosted on a site called craft cult, it's the most useful Etsy tool I have found (one useful thing about the forums).

What I find most useful thing my heartomatic is seeing the ratio of views to hearts - a very crude tool to see what stock is popular.
