100 listings is a sweet spot when you should see some traffic to your shop.

But it is all about the first 5 start reviews. Once you get your first reviews, Etsy will take your shop seriously.

Most sellers are doing this... they take 20 - 50 dollars and select the best listing. Then they put these money into the Etsy ads... just 2 or 3 dollars a day can get you the first sales and reviews.

This is the speedrun for a shop. Or you can wait one or two months, then you should already see some sales from organic traffic.
