Image & reputation
What people think & feel about the brand
What people think about a brand is shaped far more by experience than by advertising.
Image is how the brand is perceived at a specific moment; reputation is the accumulated weight of how it has behaved over time. Both are shaped by every interaction someone has with the brand, from the product itself to customer service to what they read in the news. Brands can influence these, but they cannot control them, only earn them.
The gap between intended image and actual image is where brand strategy most often breaks down. A brand can invest heavily in communicating a story of innovation or warmth or sustainability, and the actual experience of the product or the company can tell a completely different story. The latter always wins.
