Amazon ac label refers to the automatic level in the Amazon advertising platform, where ac is the abbreviation of Auto Campaign. In this level, advertising costs will automatically adapt to market demand, bid according to the search terms or categories of the target products, and display in Amazon search results or related product pages. Therefore, Amazon ac label is a relatively simple and easy-to-operate form of Amazon advertising.

Although it has limitations and disadvantages compared to other advertising methods, it is still a good initial choice to help sellers understand the performance of their products in Amazon searches, optimize advertising strategies and budgets, and increase sales and revenue.
