The Long Copy Argument, Revisited
The people who say nobody reads long copy are usually the people who cannot write it.
There is a lie that has been circulating in our industry for at least twenty years, and it has now been repeated so often that it has acquired the appearance of truth. The lie is this: nobody reads long copy. I have heard it from creative directors, from planners, from clients, and most frequently from young copywriters who have never been asked to write anything longer than a tweet. It is a convenient lie, because it excuses laziness. If nobody reads long copy, then there is no need to write it. If there is no need to write it, then there is no need to learn how. And if there is no need to learn how, then the entire discipline of persuasive writing — a discipline that took a century to develop — can be quietly abandoned without anyone having to admit they were not up to the task.
I do not believe this lie, and I have thirty years of evidence to support my scepticism.
Let me begin with a distinction that is often overlooked. There is a difference between long copy and unnecessary copy. Long copy is copy that takes as many words as it needs to make its case, and not one word more. Unnecessary copy is copy that is long because the writer did not know when to stop, or because the writer confused volume with thoroughness. The argument against unnecessary copy is unanswerable. No one should write more than the subject demands. But the argument against long copy — against copy that earns its length — is an argument against persuasion itself.
Claude Hopkins understood this in 1923, when he wrote in Scientific Advertising that the more you tell, the more you sell. He was not guessing. He was working from direct response data — from millions of coupons, from split-run tests, from the hard, unforgiving arithmetic of what works and what does not. Hopkins knew that a prospect who is genuinely interested in a product will read a great deal about it, provided the writing rewards their attention. The prospect who is not interested will not read a single word, no matter how short you make it. The length of the copy does not determine whether it is read. The quality of the copy determines whether it is read. The relevance of the copy determines whether it is read. The length is a consequence of having something to say, not a cause of failure.
The Evidence I Have Seen
In my years at the agency, I worked on three major direct response campaigns that tested long copy against short copy in controlled conditions. In every case — every single case — the long copy outperformed the short copy. Not by a marginal amount. By factors of two and three. The products were different, the audiences were different, the media were different. But the result was the same. When you give a reader the information they need to make a decision, and you present that information in a way that is interesting and persuasive, they will read to the end. And when they read to the end, they are far more likely to act.
I recall one campaign in particular, for a financial product that was genuinely complex. The client wanted a short advertisement — something clean, something modern, something that would not intimidate the reader. I understood the instinct, but I disagreed with the conclusion. We ran both versions. The short version was handsome. It had white space. It had a strong headline and a compelling image. It said almost nothing. The long version was dense. It had subheadings and bullet points and a detailed explanation of how the product worked and why it was worth the reader's money. The long version generated three times as many qualified leads. Not three times as many clicks or impressions — three times as many people who actually picked up the telephone and spoke to a salesperson. The client was astonished. I was not.
The lesson is simple, and it is one that Ogilvy stated clearly: the consumer is not a moron, she is your wife. People do not resent being given information. They resent being given information that is boring, irrelevant, or insulting to their intelligence. The solution to boring long copy is not short copy. The solution to boring long copy is interesting long copy.
Why the Industry Turned Against Length
I have a theory about why the advertising industry turned against long copy, and it has nothing to do with consumer behaviour. It has to do with the people who make the advertisements. Sometime in the 1990s — I cannot pinpoint the exact year, but I felt it happening — the balance of power in agencies shifted from copywriters to art directors. This was not a conspiracy. It was a natural consequence of the visual turn in media. Television had been dominant for decades, and now the internet was arriving, and both were visual media. The art director's eye became more valued than the copywriter's ear. Advertisements became shorter, cleaner, more dependent on imagery. The copy shrank to fit the layout, rather than the layout expanding to accommodate the copy.
There is nothing wrong with visual communication. Some of the greatest advertisements ever made — the Volkswagen "Think Small" campaign, for instance — achieved their effect through the brilliant interplay of image and text. But "Think Small" was created by a copywriter, Julian Koenig, working in concert with an art director, Helmut Krone. The copy was spare because the subject demanded it. A small car needed a small advertisement. The restraint was purposeful. It was not a template to be applied to every product in every category.
What happened instead is that restraint became fashion, and fashion became dogma. Agencies began to produce work that looked beautiful in portfolios and won prizes at Cannes but did not sell anything. I watched this happen. I watched talented writers abandon their craft because the industry told them their craft was no longer needed. I watched clients accept advertisements that said nothing because their agencies told them that saying nothing was sophisticated. It was not sophisticated. It was empty.
The Digital Paradox
Here is the irony that I find most striking. The digital age, which was supposed to kill long copy, has actually created the conditions for its revival. People now spend hours reading on screens. They read long articles, long reviews, long threads. They read ten-thousand-word investigations in the New York Times and the Guardian. They read product reviews that run to multiple pages. They read, in other words, whenever the writing is good enough and the subject is relevant enough. The attention span has not collapsed. It has become more selective.
And yet the advertising industry, which should be at the forefront of written communication, has largely retreated from the long form. We write banner ads and social posts. We write slogans. We write captions. We do not write arguments. We do not build cases. We do not take the reader by the hand and walk them through a proposition, step by logical step, until they arrive at the conclusion we intended. This is not because the opportunity has disappeared. It is because we have forgotten how.
I am not arguing for long copy in every situation. That would be as foolish as arguing against it in every situation. Some products need very little explanation. Some audiences have already been persuaded and need only a reminder. Some media do not accommodate length. The thirty-second television spot is not the place for a thousand words of body copy, and I am not so foolish as to suggest otherwise. But when you have a complex product, a sceptical audience, and a medium that allows for length — and the internet is precisely such a medium — then long copy is not just appropriate. It is necessary.
How to Write It
If you will indulge me, I would like to offer a few principles for writing long copy that actually works. These are not rules. Rules are for people who do not understand principles. But they have served me well over three decades, and I believe they are sound.
First: begin with a fact that surprises. The reader has given you their attention provisionally, and you must reward that gift immediately. A surprising fact — specific, verifiable, unexpected — tells the reader that you have something to offer that they did not already know. It earns you the right to continue.
Second: organise your argument. Long copy is not a stream of consciousness. It is an architecture. Each paragraph should advance the case. Each section should have a purpose. The reader should feel, at every point, that they are moving towards a conclusion. If they feel lost, they will stop reading. If they feel they are in capable hands, they will continue.
Third: use subheadings. This is not a concession to laziness. It is a recognition of how people read. Subheadings serve as rest stops, as signposts, as invitations to re-engage. A reader who is scanning — and most readers scan before they commit — uses subheadings to decide whether the full text is worth their time. Good subheadings can persuade on their own.
Fourth: end with conviction. The last paragraph of a long-copy advertisement is not a summary. It is a call to action, a final appeal, a statement of belief. It should have the force of a closing argument in a courtroom. The reader who has stayed with you to the end is ready to be persuaded. Do not waste that moment with timidity.
And fifth, above all: be interesting. This is the hardest principle and the most important. Long copy that is boring is worse than short copy that is boring, because it wastes more of the reader's time. Every sentence must earn its place. Every paragraph must justify its existence. If a sentence does not inform, persuade, or entertain, cut it. If a paragraph does not advance the argument, remove it. The discipline of long copy is not the discipline of writing more. It is the discipline of writing more that matters.
The people who say nobody reads long copy have never written long copy worth reading. That is not an argument against the form. It is an argument against the writer.
