The most common form of non-price competition is advertising.
Non-price competition refers to ways that businesses compete without changing the price of their products or services. While there are several strategies, advertising stands out because it helps create brand awareness and influences consumer perception. Through advertising, companies can communicate the benefits and features of their products, differentiate themselves from competitors, and build customer loyalty, all without adjusting prices. Other forms like collusion, diversification, and specialization might play a role in competition, but they are not as widespread or effective as advertising in capturing consumer attention and driving sales.
