AI can speed up marketing tasks such as drafting and repurposing content, but that alone does not show that marketing has improved. Better outcomes still depend on the quality of the brief, the choices people make, and whether the work achieves its intended effect. The claim that AI made marketing faster without making it better is a useful practitioner argument—not a proven verdict across marketing teams or campaigns.
What does “faster, not better” mean?
It separates the speed of producing an asset from the quality of the decisions behind it and the results it delivers. AI may help a team create a first draft or several alternatives quickly. But a draft is not a strategy, and a larger set of options is not automatically a more effective campaign.
In her commentary, Kath Pay argues that “The output quality still depends on the thinking quality that went into it.” Her point is that faster execution cannot, by itself, fix a vague brief, an unclear audience, an unresolved proposition, or criteria for success that were never defined. This is a practitioner’s interpretation of the workflow, not a measured finding about all marketing teams.

Has evidence shown that AI only speeds up marketing?
No. The available findings are task-specific and do not establish a single industry-wide answer. They measure different work, populations, and outcomes; none measures whether marketing overall became faster without becoming better.
#1 Best Overall
| Evidence | What was studied | What it can support | What it does not establish |
|---|---|---|---|
| Gastmann and Bastos (2025), Strategising with generative AI: Productivity gains in social media marketing | Interviews with 20 social media professionals and a follow-up strategy-generation experiment involving two companies. | The authors’ abstract reports productivity potential and high-quality strategy output in terms of brand fit, fit to business challenges, and strategic flexibility. It also flags intellectual-property and data-protection requirements. | A general improvement in marketing performance across companies, channels, or campaigns. |
| Noy and Zhang (2023), randomized experiment | 453 college-educated professionals completed occupation-specific writing tasks. | In those tested tasks, average completion time fell by 40% and assessed output quality rose by 18%. | Those figures do not measure campaign effectiveness or marketing quality overall. |
| Organization Science field experiment (2026) | A preregistered field experiment involving 758 knowledge workers and tasks that varied in their fit with the tested AI capability frontier. | Participants using AI performed better on tasks judged within that frontier, but were less likely to produce correct answers on a complex managerial task outside it. | A marketing-wide verdict. The result illustrates uneven performance across tasks, not a direct test of campaign outcomes. |
Together, these findings make a simple “AI only makes execution faster” claim too broad. AI can contribute to strategy work in some conditions, and measured benefits vary with the task. At the same time, faster writing or strong performance on bounded tasks is not proof that a campaign persuaded the right audience or improved business results.
Why can generating more content leave the real work untouched?
Production is only one part of a marketing workflow. Teams still have to decide what problem they are addressing, whose behavior they want to influence, which proposition is credible, and what evidence would count as success. If those decisions are unresolved, AI can produce polished material without resolving the underlying uncertainty.

More variants can also mean more work for reviewers. Without agreed criteria, reviewers may debate tone, claims, or audience fit one asset at a time. AI has increased the number of choices, but the team has not established a way to choose among them. Kath Pay’s related argument is that “AI can’t resolve these judgment questions. But it highlights the need for humans to step in.”

An improvement in one does not automatically prove an improvement in the other.
How can you use AI to improve a marketing brief before generating copy?
Use AI first to examine the problem and expose gaps—not just to turn an incomplete brief into fluent text. A useful brief connects the communication to a customer situation, a desired behavior, supporting evidence, and a measure that can guide a decision.
- State the job of the communication. Identify where it fits in the customer journey and what the audience should understand or do afterward.
- Describe the audience’s mindset. Specify what the intended audience already knows, wants, questions, or doubts. Avoid treating a broad demographic label as a substitute for customer context.
- Define the intended behavior. Say what action or change the campaign should influence, rather than asking only for a general goal such as “raise awareness.”
- List the evidence behind the brief. Separate supported facts about the customer, offer, and market from assumptions that still need checking.
- Set decision criteria before requesting alternatives. For example, decide what an option must demonstrate about audience relevance, proposition, brand fit, or substantiation. Choose criteria suited to the campaign rather than treating any example list as universal.
- Specify how success will be judged. Choose a measure that corresponds to the intended behavior and explain how it will inform a decision. Do not wait until assets are finished to decide what to measure.
- Ask AI to find gaps and challenge assumptions. Prompt it to identify missing information, questions a customer might ask, and claims that the available evidence does not support. Treat its suggestions as prompts for review, not as proof.
Where should AI fit in the workflow?
Once the brief and criteria are clear, AI can help generate options, draft or adapt content, and organize information. Keep a human decision-maker responsible for choosing among the options, checking customer fit and claims, and interpreting results.
- Use it for options, not automatic approval. Compare generated alternatives against criteria the team already agreed on.
- Review claims against evidence. Fluent wording does not establish that a product claim is accurate or supportable.
- Keep company and customer context in view. Generic output may miss the business challenge or audience details that make a strategy appropriate.
- Protect sensitive information. The 2025 marketing study specifically flags intellectual-property and data-protection requirements. Teams should account for those constraints when deciding what information to use with an AI system.
- Interpret results rather than just summarize them. A summary can organize evidence; people still need to judge what changed and whether the campaign created demand, captured existing demand, or merely discounted it.
How should a team tell whether AI made marketing better?
Evaluate speed, quality, and outcomes separately. A shorter production cycle is a speed result. A stronger asset against defined criteria is a quality result. A change in the behavior or business measure the campaign was meant to influence is a downstream result. One does not stand in for the others.

Then check whether the extra capacity went toward better decisions or simply more output. Compare the finished work with the brief and the success measure, and be careful not to attribute an outcome to AI solely because AI was used in production.
The evidence supports a more careful conclusion than either “AI makes marketing better” or “AI only makes it faster.” Its contribution depends on the task and context, while strategic choices and interpretation remain consequential. Pay’s thesis is best read as a warning: faster production does not repair weak thinking, and producing more does not prove that customers responded better.
