    Gone are the days when your customers used to buy products and services for its benefits. Today, your customers are being flooded with 100 ads each day. They know they are being sold to, which has led customers to become hyper-critical of everything you say in your sales copy. They know that the solution being offered to them will help them, but they don’t trust the message or the person it is coming from. What happens eventually is they end up buying zero products, regardless of how many ads you show them. The golden question: How can you differentiate yourself from the ocean of brands selling the same product? The answer: EMPATHETIC SALES COPY! We all want to feel humans first, customers second. And we love it when salespeople talk to us like humans, not wallets. Empathetic copywriting requires you to connect with your customer on an emotional level first. Once they consider you a part of their tribe, they let down their guard and closing becomes a walk in the park. Once you offer them empathy, they trust only you and not the 100 other companies; and never second guess what you tell them. You might be thinking how will this guy develop empathy for my customers; he hasn’t even met them? It’s quite simple, you see. All you need to do is hang out with them online. You need to follow them everywhere they go. Follow their conversations on online forums, FB groups, blogs and any other spaces where they are pouring their heart out. Read their agitating and frustrating comments on YouTube and Twitter. I take insight and inspiration from wherever I can about what makes your customer tick; and use it in my copy to make it more personal and empathetic for your reader. Lastly remember, the connections I create for your brand through my empathetic copywriting will guarantee lifelong loyal customers who keep coming back, and not one-off sales. If you have made it this far, just take the first step by placing your trust in my empathetic copy; so that I can help you place the trust of your brand in your customers. All you need to do is click the invite button on my profile and let me handle the rest. P.S: If you just want another traditional Salesy Susan that translates your features to benefits, you might be in the wrong place.
