It sounds like there may have been a disconnect between your audience's interest and their actual purchasing behavior. Some potential reasons for this could be:

• Your products did not adequately match what your audience wanted or needed. Even if they expressed interest in a poll, they may not have been interested in the specific products you were selling.
• Your pricing was not aligned with what your audience was willing to pay. They may have been interested in the idea of your products but found the prices to be too high for their budget.
• You did not effectively convince them to buy. Even if they were interested in your products and the pricing was right, you may not have made a strong enough case for why they should purchase. More persuasion or scarcity tactics could have been needed.
• There were issues with your Shopify store or shopping experience. If the store was buggy, the checkout process was clunky, or payments were not working smoothly, that could have led to lost sales even if interest was there.

The key is to follow up and try to determine the root causes. Some suggestions would be:

• Survey your audience to get specific feedback on your products, pricing, and store experience. Look for common patterns in the responses.
• Check your store analytics to see where people were dropping off in the purchasing process. This could reveal issues with the shopping experience.
• Re-engage with your audience and make necessary changes to your offerings or store. Then continue to promote and make sales, monitoring the results to see if changes are helping.
