When people do not know they need a product, they will not search for it by name. So the smart move is to target the problem they are already searching for. If you sell noise-cancelling wallpaper, you run ads for things like "how to reduce noise in apartment" or "noisy neighbors solution." You meet people at the point of their problem, not the product. Display ads also help here since they show your product to people while they browse. So what do you think is the most effective way to reach buyers who do not know your product exists?
