1. Consider the details.
You don't have to drown your product/service descriptions in a sea of descriptive words. It is best to choose details that carry a lot of meaning. Think about words and phrases that relate to what you offer and that give the reader a sense of a particular feeling/setting/custom.
2. Include sensory words.
It's easy to only talk about how something looks. Great product/service descriptions are inclusive of all the senses - sight, sound, smell, taste, and touch.
3. Go beyond the obvious.
There are things that are obvious and don't need describing. So instead of pointing out the obvious, talk about other aspects that give the reader a broader sense of your product/service.
4. Describe the experience.
When someone buys a product/service, they are also buying an idea of a lifestyle, of a setting, or an experience. As someone who is selling a product/service, you are thinking from your perspective that, in truth, may be slightly different from how your customers would think/feel. So for a moment, remember a time when you were a customer in a similar situation and think about a memorable experience and describe that. If a memory is strong enough to use, it can be included in your product/service descriptions.
5. Be specific.
All the details, all the sensory words, and everything else that you write about your product/service needs to be specific.
Writing about hammocks in general is not the same as writing about YOUR hammocs. All hammocks function in a similar way, while there are, of course, differences between outdoor and at-home hammocks, but tell your prospective customer how YOUR hammock is different because of how well the materials compliment the intended use/setting etc.
