Some products have benefits that are complex, uninteresting, or even socially unacceptable to talk about.
In such instances, explore the analogy approach.
Although it can be argued that using an analogy is borrowing interest from another topic, it is a useful tool.
In many cases, it might even be the only effective tool.
An analogy can infuse a boring product benefit with much needed emotion and memorability.
As with the previous tool, remember that the success of this approach depends on the word, phrase or line that links the analogy with your product.
