Our cloud service takes into account the following product fields: title, description, sku, SKU, and product attributes (that you would want to sync). We then use proprietary learning algorithms that constantly measure usage in order to present end-users the most relevant products.
In order to make sure we are reading the right info for your search, open our Dashboard > Sync tab.
Scroll down and select which info you would like us to scan from your BigCommerce site.
For Product Attributes - add them to the section dedicated to them, and click on the update button. It make take up to an hour to fully sync the inventory's product attributes that you selected to sync.
