This document summarizes key concepts from the 1981 book "Positioning: The Battle for your Mind" by Al Ries and Jack Trout. It discusses how positioning involves claiming a unique position for a product in the consumer's mind. First movers have an advantage, so a non-first product must find an unoccupied position. Leaders should reinforce their status without boasting and introduce related brands. Followers must find unique positions rather than trying to appeal to everyone. Repositioning competitors or changing perceptions of them can also be effective strategies. The name of a brand is very important in shaping consumer perceptions.
