It is my understanding that you need to have the primary keywords in the first 3 words of the title, followed by secondary keywords, with lesser important words near the end. Copy this exactly for the first line of the description, and of course use a lot of those phrases also in the tags. This way you are super relevant both for Etsy and for Google.
