The picture below should give you nightmares:

People love to criticize, especially when it's safe and easy. Plus, for folks outside of marketing (Cassie from IT, I see you!), this activity is a fun break from their day-to-day.

As a result, we, marketers, often get bombarded with useless opinions disguised as "feedback" — a bit like asking a toddler to judge a Michelin-star meal.

If you really, really, really need input from others, my recommendation is to:

• Clarify exactly what you want to find out from this exercise,
• Design ultra-specific questions that are there to fill the gaps you've identified. For example, "Given we seek to be noticed by [segment] and our goal is to make them do [action], do you think this ad will reach its objective?"
• Take feedback with a pinch of salt; nothing beats real behavior from real people in real-life settings.

This way, you'll get better insights and avoid drowning in pointless opinions.
