The one sentence every expert needs

Someone at a dinner asks what you do. You start talking, and forty seconds later you're still explaining. Their eyes have drifted. They nod politely and move on.

That moment happens online thousands of times a day. On your website, your LinkedIn, your podcast bio. And now in AI answers, where a machine tries to summarise you in a line and often gets it wrong because you never gave it a clear line to use.

The sentence that does the work

Every expert needs one sentence that explains what they do so clearly that someone else could repeat it. Not a tagline. Not a mission statement. A plain sentence with three parts:

• Who you help
• What you help them with
• The result they get

"I help first-time managers in tech lead with confidence in their first year." "I help family businesses in East Africa prepare the next generation to take over." "I help coaches become the obvious answer in their field."

Why it feels hard

Because it means choosing. Most experts can help lots of people, so naming one group feels like turning others away. But the sentence isn't a fence. It's a signpost. It tells the right people they're in the right place, and it gives everyone else something simple to pass on.

People can't recommend what they can't repeat.

How to write yours

1. List your five favourite clients. What do they have in common?
2. Write down the problem they came to you with, in their words, not yours.
3. Write down what changed for them after working with you.
4. Combine it: "I help [who] [do or overcome what] so they can [result]."
5. Say it out loud to three people outside your industry. If they can repeat it back, it works.

Then use it everywhere

The same sentence goes at the top of your website, in your LinkedIn headline area, in every bio and in your schema markup. Consistency is what turns a sentence into a reputation, for people and for AI.
