I see 485 items listed/shown in your shop. Should there be more?
I see a total of 485 items listed (all listings). But when I add up the number of listings by section, I only get 343, so you have a fair number that are not in any sections. I think in the listings manager there is a way to search for listings that don't have a section.
You can check to see if items are in a section by using quick edit, up in the right hand corner of the listing page in shop manager. Even if they aren't in a section they are still in your shop for sale.
If you have listings that you know you have done but they don't show up, check your deactivated section in the listings manager. I'm not saying you should have them but I did a listing and Etsy automatically deactivated it for having the Major League Baseball, MLB letters. It was vintage wrapping paper and once I had them look at it, it was reinstated. Usually you get an email if that happens.
Some of your original listings may have expired. I see you opened in June of last year and the listings only stay up for 4 months unless they are sold or they are deactivated or deleted. Look in your "expired" section under "listings" in your dashboard and see if there are some that expired.
Has Etsy deactivated any of your listings?
If you can answer the questions asked in your thread, people will be better able to help you.
I see lots of items in your shop. Are you sure the newly added items do not show up?
Wish you luck!
