The same tool that helps you find your best customer can also be used to find someone’s fears, anger, or bias. That’s where smart marketing turns into something a lot messier.

In this conversation, from our archive, we unpack market segmentation, the good it can do, and the risks that come with it. Recorded in 2017 many of the same concerns are still valid today.

I chatted with Lydia Thurston and Sam Von Tobel about demographics, psychographics, and why every business owner should understand both sides of the story.

Why this matters: Targeting helps you spend less and connect faster. But when powerful tools land in careless hands, the results can get ugly.

Takeaways:

• Good targeting saves time and money Demographics help you narrow by age, gender, income, or location. Psychographics help you understand interests, values, and habits. Together, they help you reach moms looking for cooking classes or families searching for healthy meal ideas, instead of shouting into the void.
• The same data can be misused We talked about the ProPublica case, where ad targeting tools were tested to reach groups based on hateful beliefs. That’s a wake-up call. These systems don’t just sell soup and cooking classes. They can also spread division if no one is paying attention.
• Just because you can target someone doesn’t mean you should Marketing always needs a moral compass. It’s easy to get excited about precision and forget responsibility. Smart business owners need both.
• Platforms have work to do Facebook responded by blocking some harmful terms, but the bigger challenge remains. People can still be reached through indirect signals like music tastes, interests, or online behavior. This problem doesn’t disappear with one patch.

If you use targeting tools, ask yourself, will this help my customer, and would I be comfortable explaining how I used it?
