Hi Janine,
You need to add certain pieces of markup to your template. I'm using the "OpenLink Structured Data Sniffer" extension for Chrome to look at your website and it looks fine, see the attached screenshot to see the structured data it finds for one of your product pages. What makes you think that the products aren't being indexed correctly?
I'm offering free -- no cross-selling, upselling, or other pitches -- one hour-long video calls where I'll give you my advice or technical assistance on whatever you'd like. I'm only asking for 15 minutes in return to talk with you about your experiences as a Shopify user. If you're interested, there's details in my signature, or you can see this post for more details: https://ecommerce.shopify.com/c/ecommerce-design/t/i-m-offering-free-advice-and-assistance-1-hour-personal-video-call-390377
Hope that helps,
Jesse
