What do we call firms that market similar or substitute products within the same geographic area?

The correct term for firms that market similar or substitute products within the same geographic area is "product competitors." Product competitors refer to companies that offer similar goods or services that fulfill the same consumer needs. These firms vie for the same market share by providing alternatives that might attract the same customer base.

While "brand competitors" refers to companies that offer products under different brand names but in the same product category, "generic competitors" typically describe firms that provide products that serve the same function but may not fit into a particular brand or type. "Comopetition" seems to be a typographical error and does not represent a recognized marketing term.

Understanding the distinctions between these various types of competition helps businesses formulate their marketing strategies effectively. By recognizing product competitors, firms can identify their direct rivals and develop tactics to differentiate their offerings, optimize pricing, and create targeted marketing campaigns to attract consumers in the same geographic market.
