Micro-conversion refers to a small and specific action taken by a user on a website or digital platform that indicates progress towards a larger goal or desired outcome. It is a measurable step in the customer journey that may not directly result in a sale or conversion, but contributes to the overall success of a business. Examples of micro-conversions include signing up for a newsletter, adding items to a wishlist, or watching a product demo video. These actions provide valuable insights into user behavior and can help businesses optimize their marketing strategies to ultimately drive macro-conversions.
