Evie: Absolutely stunning dolls! Gorgeous. I enjoyed browsing. Couple things:
In all of your text - especially with the new format - the openers are key. Not only because you need to grab buyers right away (that's always been the case) but in the new format, the first lines everywhere take on more importance. So sit down and try to figure out what your main selling points are - for your shop as a whole, and for each item that you sell. Then say those things first in the appropriate places.
It also helps in the new format to leave out unnecessary words. Etsy used to be a lot more casual and friendly than it is now. It's becoming slightly more commercial in its presentation. For example, your announcement could start out something like "SALE! 50% off." Then the most important few words about your dolls.
Avoid a string of phrases anywhere (except titles). Use natural sounding sentences or outside search engines might read them as spam and downgrade you in results.
Have you carefully researched your SEO? If so, make sure to use the phrases from your title in your description as well. Same exact phrases, but woven into normal sounding sentences.
Hope these few comments help! Best of luck to you!
