Hi Beverly,
I am so sorry I didn't get back to you sooner.
Tags are used to sell your items in your shop.
The tags are very important because, it's how shoppers will find your shop, and your items. The title you use should match the tags you use.
The search engines use key words such as Vintage, Handmade, Genuine, Hand Crocheted, what ever pertains to the item you are selling.
Hope this helps.
