It is not features of product, which persuade people to buy it, but the benefits related to it would bring them. So, it doesn't matter what you are selling, but it is the advantages of a product that attract more customers.

Why do you buy toothpaste? Not just for cleaning your teeth, toothpaste prevents you from having bad breath that will leave bad impression on your girlfriend/ wife or the interviewer. It not only makes your mouth taste fresh but also prevent teeth from rotting or falling out.

Same is the case with luxury cars like BMW or Ferrari. Why do people buy them? Just for the prestige of owning a luxury car. That is why ads for such cars stress these points in sales copy. All words are deliberately written to arouse desire within potential customers. People buy a particular product because of many common reasons like:
  • To make more money
  • To save time
  • To save money
  • To have things better than others
  • To reduce work or efforts
  • To have fun
  • To get a bargain
  • To feel good about themselves
  • To satisfy their curiosity
There can be an unexpectedly long list of reasons why people buy products and you may also come out with other reasons as well. You will always find a “so that” attached to everybody’s purchase. Like we don’t buy aspirin because we have a headache, we buy it so that we can get rid
of the headache. There are many people who want money just to have it, still they want more money so that they can have something else they would love to buy.

The moment you realize that emotions are attached to buying, you will understand what buyers feel when they consider buying a product. If you consider the same feeling while advertising your product or service, the chances of increased sale are far better.

So, be sure that you keep your buyers and target market in mind while advertising a product or service. The best method of designing an ad is empathy. Think the way your buyers will think and feel. Come with different ideas of portraying the benefits of product in the advertisement.

Never tell the prospects that buyers need your solution to their problem. Instead, write the copy giving an example that something has happened to you, your friend or family member, which they can relate with. If they are able to think that the situation is exactly how it will be for them too, you are successful in holding their interest.
 
Another best strategy to increase your sales is by listing all the benefits of the product and some testimonials of users in the advertisement. Always be truthful. Lying to get a sale does not provide any benefit to you but on the other hand, will spread bad reviews about your product.

Remember that you are selling a solution to the problems of people, so it is essential for you to understand the needs of customers and find out how they are affected by it.
