In an emergency saying, “you in the red shirt, come here!” is more effective than asking anybody for help, because people are more likely to act if they know who you’re talking to and what to do.
Your business may not be the same as an emergency situation, but bringing business in can be just as scary sometimes. We have an exciting opportunity to motivate customers to follow through, so creating personal messages just for them is going to be key. It’s also true that people don’t come to your website in groups, they visit you online personally. It’s best to speak to them where they’re at.
