Dave has a saying he repeats to every junior creative who walks into his office: "A bad brief is the most expensive thing in advertising."
Not a bad ad. Not a bad media buy. A bad brief. Because a bad brief produces bad creative, which produces bad campaigns, which wastes every dollar you spend putting that campaign in front of people.
Before you open Ad Legends and start generating anything, you need to spend a few minutes getting clear on three things:
- What is your campaign objective? What do you actually want people to do, think, or feel after seeing your ad?
- Who is your audience? Not a demographic range — a real human being you're trying to reach.
- What is the human truth? The emotional insight at the center of your brand that makes it worth caring about.
Get these three things right, and everything that follows gets dramatically easier.
Pro Tip: Write your answers to these three questions in plain language before you open Ad Legends. Don't overthink it — a paragraph for each is plenty. This becomes the raw material for your brief.
Defining Your Campaign Objective
Your campaign objective is not your business goal. Your business goal might be "increase revenue by 20%." Your campaign objective is the specific thing you want advertising to accomplish in service of that goal.
Ad Legends is built around four primary campaign objectives:
- Brand Awareness — You want more people to know you exist and understand what you stand for
- Lead Generation — You want people to raise their hand and express interest
- Sales Conversion — You want people to buy something, right now
- App Install — You want people to download and use your app
Your objective choice matters because it shapes the creative output. Awareness campaigns need emotional resonance and memorability. Conversion campaigns need clarity and urgency. The AI understands this distinction and adjusts accordingly.
The Objective Trap
The most common mistake Dave sees is marketers who want their campaign to do everything at once — build awareness AND generate leads AND drive sales. This produces unfocused creative that does none of those things well.
Pick one primary objective. Be ruthless about it. You can run multiple campaigns for multiple objectives — but each individual campaign should have a single, clear purpose.
Key Insight: The most awarded campaigns in history almost always have a single, crystal-clear objective. Dove's Campaign for Real Beauty was about one thing: redefining beauty. That clarity is what made it powerful enough to run for two decades.
Describing Your Audience Like a Real Person
Here's a test Dave uses: read your audience description out loud. If it sounds like a slide from a market research deck, it's not specific enough.
"Women 25-44 with household incomes above $75,000" is a media target. It's not an audience.
"Sarah, 32, a marketing manager in Chicago who just bought her first condo and is trying to figure out how to make it feel like home without blowing her budget" — that's an audience. You can picture her. You can imagine what she worries about, what she laughs at, what she scrolls past and what makes her stop.
When you write your audience description for Ad Legends, write it like you're describing a real person. The AI will use that description to calibrate the tone, the cultural references, the emotional register of everything it generates.
This is the hardest part — and the most important.
The human truth is not a product feature. It's not a competitive advantage. It's the emotional insight that connects your brand to something real in people's lives.
To find it, Dave asks three questions:
- What does your brand actually do for people's lives — not what it sells, but what it enables or changes or makes possible?
- What do people feel when they use your product or service at its best?
- What would people miss if your brand disappeared tomorrow?
The answers to those questions, distilled into a single sentence, is your human truth. It's the foundation of your brief — and the seed of your big idea.
Pro Tip: If you're struggling to find the human truth, try this: ask your best customers why they chose you. Not what features they like — why they chose you. The language they use is almost always closer to the human truth than anything your marketing team has written.
Once you can answer these three questions clearly — objective, audience, human truth — you're ready to open Ad Legends and start building your brief. In the next lesson, Dave walks you through the Brief Builder step by step.
