LimeSpot's AI Engine currently only uses the English language for product attribute detection. If your products are in a different language, the best way to optimize LimeSpot's engine is to either add English Item Types on your eCommerce platform or add English product tags for the product on your eCommerce platform.
An example is if you have a product that is a shirt and the product name is in Spanish: Camisa. In the product tags for the camisa product, add "Shirt" as a product tag to it so that the LimeSpot engine will catch and identify that product correctly. Additionally, adding more English tags, such as color, pattern, etc. would further help the optimization of your ads.
