Don't lose potential customers by failing to clearly outline how what you offer solves a problem they have - that is the really crucial point you have to make!
In any "Sales 101" class, they teach that you sell on benefits, not features.
If a site visitor reads about your space-age vacuum cleaner, they might be mildly interested about its 10 different cleaning accessories. However, when you point out that they will be able to clean in tight corners, vacuum their cushions and upholstery, and to get their floors as clean as a whistle - now your readers can easily see how it solves a problem they have.

What they really want is something that will make their life easier, or that will effectively solve a problem they are facing.
