Copywriting
Copywriting is the writing in ads, landing pages, emails, and scripts whose objective is a sale or another measurable action. The field often splits this work into brand copy, which is supposed to build awareness, and sales copy, which is supposed to convert. The split does not hold up in practice: every piece of copy a prospect reads either moves them toward a purchase decision or it does not, and the cost of producing and distributing it appears on the P&L either way. David Ogilvy's standard for the whole discipline was "We sell or else" (David Ogilvy, Ogilvy on Advertising, 1983).
How it actually works
Copy is a selling instrument with a financial objective. That framing determines how it is written and how it is judged. A headline is evaluated by whether the right prospect keeps reading, a page by whether it produces the action it was built for, a script by what the resulting ads return against what they cost. Copy that cannot be evaluated this way has no defined job, whatever its production quality. Copy is also the only creative variable that can be changed after launch at zero marginal cost: a headline, a page, or a script line can be rewritten without reshooting, re-editing, or rebooking anything, which makes it the first place to intervene when a live campaign underperforms and the cheapest variable to keep testing after the production budget is spent.
What the copy needs to say depends on what the prospect already knows. Eugene Schwartz formalized this in Breakthrough Advertising (1966) as stages of awareness: a prospect who already knows the product and wants it needs different copy than one who knows the problem but not the solutions, or one who does not yet recognize the problem. Copy calibrated to the wrong stage fails regardless of how well it is written, because it answers a question the prospect is not asking.
The language itself comes from research. Reviews, interviews, support conversations, and community discussion show how buyers describe the problem, what they compare the product against, and which objections stop them. Copy assembled from that record uses the words the market already uses. Copy invented internally tends to describe the product the way the company thinks about it, which is rarely how a buyer does.
In practice
At Potbelly, repositioning the message from the product to the customer's desired outcome, a copy decision, preceded revenue growth of 30% and then 19% year over year. Copy that holds attention also disproves the 8-second attention span figure: one of our longest-running ads ran over 3 minutes at 80 to 90% watch retention for almost 3 years, needed a single one-word edit after an algorithm update, and took a business from $300k per year to $20M per year and a healthy exit. The case is documented in [the attention span fallacy](/insights/why-your-vendors-win#the-attention-span-fallacy).
Where we come in
We build on the formulas from Eugene Schwartz, tailoring the customer journey to the prospect's needs and perspective, and we hold to Ogilvy's standard: we sell or else. If it isn't backed by data within the target market, it doesn't end up in scripts or ad creative. We test small and prove the message before investing in anchor content.

- Awareness stages
- Eugene Schwartz's framework from Breakthrough Advertising: what copy must say depends on whether the prospect knows the product, the solution category, the problem, or none of these.
- Direct response
- Copy built to produce a measurable action now: a purchase, a signup, a booked call. The response is the measurement.
- Message-market match
- The degree to which copy addresses what the market is actually weighing: the problem as buyers describe it, the alternatives they consider, the objections that stop them.
- Customer language
- The words buyers use in reviews, interviews, and support conversations. The source material for copy, gathered rather than invented.
- Offer
- What the prospect gets, at what price, on what terms. Copy presents the offer; a weak offer is not fixable at the copy layer.
