Sing to the tune of the Seven Dwarves' "Hi ho, hi ho..."
"SEO, SEO, it's what makes our sales grow..."
That's Search Engine Optimization, and it's how to write your listing titles, descriptions and tags so that your customers can find you. There is a whole team dedicated to it. "Etsy Relevancy, SEO and Stats"
Join this team. There are lots of really smart people on it who generously share their knowledge:-) I am still new, but the experienced sellers all say the same thing. SEO is really, really, important. Just take one bit at a time, and it's kind of a second language, so keep re-reading things and try a bit, then come back, and it will make more sense the more you read.

https://www.etsy.com/forums/?ref=ftr and try a search. Before posting a new question on a team, search first, as the veteran types understandably get tired of answering the same questions over and over. If you've searched the forums and the Etsy Success team AND the Etsy Seller Handbook
https://blog.etsy.com/en/2013/the-seller-handbook-archive/ with no luck, then post your question and lots of really nice people will answer. Etsy Admin is very helpful as well.
