At what point does a buyer persona mutate from a useful marketing tool into a meaningless collection of bullet points, stock headshots, and random guesses?
Are your buyer personas drowning in details? How much information is too much, and what do we truly need to know about our prospects to motivate them to respond?
Why too much detail does more harm than good
It wastes time
Researching and interviewing customers can take up a lot of time. The more research you need to do, the less likely it is that you'll get around to actually doing it.
It distracts you from what's important
Generic persona templates tend to be loaded down with obscure details, and many of them may well be useless for your specific situation. Filler that doesn't add value to your marketing process steals attention away from the insights that do matter.
It complicates the decision-making process
