Customers adding to cart but not purchasing. Why?

So I’ve been had my store running for about a week now and i’ve sold 4 items (which i’m honestly psyched up about) But ive noticed that people have been adding products to cart but not following though with the purchase but cant figure out why.One item has been added to cart 35 times and another 16 times with 0 total purchases.Any advice/help/tips would be much appreciated via /r/shopify https://ift.tt/2Q1xJIs
