I heard another Etsy member say in passing that one way they increased views on certain items in their shop was to keep an eye on the front page for keywords. If a list appears there using a certain keyword, and provided that keyword accurately applies to any items in your shop, go ahead and use that keyword.

I have done that with items that still fit the tagged word
or I will renew one that does have that word so it is right at the top
Nice! Renewing is a good tip, too. Thanks!

Great tip! I have done that with my seasonal items, but I really should do it with everything! Thanks for motivating me again to take action!
I wish you a very merry holiday season! I’m glad a came upon your blog!

Doing this has actually brought my items to the frontpage a couple of times.
