Brand awareness facilitates decision-making and is especially important for which type of consumer goods: public goods. 

Public goods are non-excludable items so there is fair game for anyone and everyone in the market for an item to make this purchase.  Because this items are everywhere, there is normally a decent amount of competing brands with the same product though packaging, quality and quantity can differentiate. Brand awareness helps the consumer know which brand to purchase when there are dozens to choose from.
