AI can produce marketing content at a rate no human team can match. The question is whether any of it should actually go out. Here's how to tell.
Over a decade of marketing campaigns, I’ve watched content production speed increase dramatically at almost every organisation I’ve worked with. It used to take two weeks to produce a solid email sequence. Now teams can generate a draft in minutes. The pipeline is faster than it’s ever been.
But speed is only a virtue if the output at the end of the pipeline is worth sending. And that’s where I see a genuine gap in how most marketing teams have adopted AI. They’ve adopted the generation part with real enthusiasm. They haven’t matched that with an equally rigorous evaluation process.
The result is what I call the content factory problem. High volume, mixed quality, inconsistent brand voice, occasional factual errors that make it through, and legal risks that nobody caught because the review was too fast. The AI didn’t cause any of these problems. Moving fast without a quality check did.
Here’s the analogy I use with marketing leads. A faster production line on a factory floor doesn’t mean fewer QA checks: it means more frequent and more efficient ones. The QA process doesn’t slow down production when it’s well-designed. It protects the reputation of everything that comes off the line. Your AI content workflow needs the same logic.
The CRAFT framework is the QA process your AI content workflow needs. It takes under ten minutes per piece of content. It catches the five failures that damage marketing brands most consistently. And it scales: once your team is running it reliably, you can automate parts of it and redirect human review to the checks that genuinely require human judgment.
CRAFT stands for Correctness, Relevance, Audience fit, Flags, and Tightness of call to action. Each dimension catches a different failure mode, and the five together cover the most common ways AI-generated marketing content goes wrong.
You can run CRAFT as a checklist, with each team member independently checking their content before it goes to review. You can use it as a structured review template in your content management system. You can build it into your approval workflow as required fields before anything moves from draft to published. The format is flexible. The five checks are not.
Let’s work through each one.
AI tools hallucinate. Not dramatically and not constantly, but often enough to matter when the output is customer-facing marketing content. In a 2026 analysis, AI systems generating marketing copy produced verifiably incorrect facts at rates between 3-8% per batch.[1] For every hundred pieces of content you generate without a fact check, somewhere between three and eight contain something that isn’t true.
What kinds of factual errors appear most often in marketing content? Product specifications that the AI has interpolated rather than sourced. Statistics from outdated research that the AI presents as current. Competitor comparisons that are subtly wrong in ways that could constitute false advertising. Case study figures that have been paraphrased into inaccuracy. Awards or certifications that the company no longer holds.
Don’t try to fact-check the entire piece at once. Identify the factual claims: the statistics, the specific product details, the named results, the attributed quotes. Each factual claim gets a verification source before the content moves forward. If you can’t find a primary source for a statistic, remove the statistic or replace it with something you can verify. One wrong number in an email campaign costs more than five minutes of checking time to fix after it’s gone out.
For high-volume content like social media posts, build a fact-check into your content brief template: every brief should note the three to five facts that can go into the post, with their verified sources attached. The writer (human or AI) works from the verified facts, not from free-form internet knowledge.
Brand voice drift is the most insidious AI marketing problem because it’s cumulative and subtle. Individual pieces of AI-generated content often pass a quick read. But over weeks and months, without consistent evaluation, the aggregate voice of your brand starts shifting in directions nobody consciously chose.
Over a decade of campaigns, I’ve seen this with enough brands to call it a pattern. The AI default voice is competent, safe, and slightly corporate. It hedges. It over-explains. It favors passive constructions. It uses modifiers like “robust,” “innovative,” and “cutting-edge” that have been drained of meaning through overuse. None of these things are catastrophically wrong in any individual piece. But accumulated across your content output, they gradually sand the edges off your brand’s distinct personality.
The most reliable method is the “could this have been written by anyone” test. Read the piece and ask: if you removed the brand name and the specific product details, could this have come from any of your competitors? If yes, it’s not distinctly your brand voice. Tighten it.
More specifically, check for: vocabulary that matches your brand lexicon, sentence length and rhythm that matches your established style, the right level of formality for your audience, and at least one line or phrase that sounds unmistakably like you rather than like polished generic content. The details matter. When AI writes blog content, this voice consistency check is what separates content that builds your brand from content that just fills a calendar.
AI writes for its conception of your audience, which is based on your prompt. The better your prompt describes your audience, the closer the output gets to the right fit. But there’s always a gap, because no prompt fully captures the texture of a real buyer segment.
This is the check where your own customer knowledge becomes the irreplaceable variable. You know things about your audience that no AI does. You know which words make them roll their eyes. You know which pain points they’re tired of seeing addressed the same way everyone else addresses them. You know what they actually say in sales calls versus what the standard industry narrative claims they care about.
The customer feedback analysis approach we’ve covered separately is a useful input to this check: if you’re regularly analysing what customers say in reviews, surveys, and support tickets, you have a constantly updated picture of what audience-fit actually looks like in your category.
This is the check that gets marketing teams into the most serious trouble when it’s skipped, and it’s the one most likely to be skipped when the content review is rushed.
AI-generated marketing content can fail on compliance in ways that are easy to miss on a quick read. Superlative claims that would require evidence to substantiate (“the industry’s most accurate,” “proven to reduce costs by 40%”). Comparative claims about competitors that could constitute false advertising if not precisely accurate. Health or financial claims that cross into regulated territory. Testimonials that are presented as factual results when they’re individual experiences. GDPR-relevant copy that implies data handling practices the company doesn’t actually follow.
Work with your legal or compliance team once to create a “red flag phrases” list: specific types of claims that require approval before going live. Share that list with everyone who reviews AI content. Add it as a field in your content approval workflow. The investment is one meeting and thirty minutes of documentation. The return is avoided legal exposure for every piece of content that goes out afterward.
For smaller teams without dedicated legal resource, the practical version is: flag any claim that sounds like a guarantee, any comparison to a named competitor, any statistic without a verifiable source, and any copy that touches on health, financial performance, or data privacy. Those categories cover the majority of compliance failures in AI-generated marketing content.
The call to action is where most AI-generated marketing content leaves performance on the table. The AI is good at producing content. It’s less good at producing the specific, urgent, audience-matched call to action that drives conversion.
AI CTAs tend toward the generic. “Learn more.” “Get started today.” “Contact us to find out more.” These phrases have been used so many times that readers have developed a specific form of blindness to them. They’re not wrong. They’re just not working as hard as they could.
For AI-generated ad copy specifically, tightening the CTA is often the single change that produces the biggest performance lift, because the AI tends to be conservative about conversion language in a way that human direct-response writers are not.
The CRAFT framework only works if it becomes a non-optional step in your content process. That means building it into the workflow, not leaving it as something people do when they remember.
Here’s the minimum viable version for a small marketing team. Create a simple checklist document with the five CRAFT checks. Add it as a required step in your content approval process, between “draft complete” and “approved for publishing.” Assign one person to own the CRAFT check for each piece of content, and make it their signature on the quality. Track the results: which check fails most often? That’s where to focus your prompt engineering effort.
For larger teams, the CRAFT check can be split between roles. The writer does the Correctness and Relevance checks before submission. A senior reviewer does the Audience and Flags checks. The channel owner does the Tightness check because they know what converts in their specific channel. This division of responsibility is more efficient than having one person check all five, and it distributes the quality accountability across the team rather than centralising it in a bottleneck.
The teams I’ve seen implement this well report two consistent outcomes after three months: fewer last-minute corrections before publishing, and a gradual improvement in the quality of the AI content because the CRAFT failures feed back into better prompts. When you know that your content consistently fails the Tightness check, you update your content brief template to include stronger CTA guidance. The evaluation loop improves the generation, and the generation quality improves over time.
The loop is the real value. Every failure you catch becomes a signal for a better prompt next time, and the generation quality improves without anyone consciously updating their process.
For a short-form piece like a social post or email, the CRAFT check takes five to ten minutes when you’re practised at it. For longer content like a landing page or article, allow fifteen to twenty minutes. The first few times take longer because you’re building the habit and refining your rubric. After a month of regular use, most team members can run it efficiently enough that it doesn’t feel like a significant overhead.
Yes for customer-facing content, including social. Social posts have a lower word count but a higher visibility risk: a wrong fact or off-brand message on social can reach thousands of people before you catch it. The check takes less time on short content anyway. The Flags and Tightness checks are especially important for social, where compliance risks and weak CTAs have an outsized effect.
Brand voice relevance (the R check) fails most consistently in my experience. AI defaults to a competent but generic voice that passes a casual read but doesn’t sound distinctly like the brand. This is also the failure that’s hardest to automate: catching voice drift requires a human with brand knowledge. The Correctness check is the most critical to catch early because its consequences are most concrete.
You can automate parts of it. Correctness checks for specific factual claims can be checked programmatically against verified data sources. Flags checks can be automated by scanning for known red-flag phrases. Audience checks can be partially automated by testing readability against audience vocabulary benchmarks. But Relevance (brand voice) and Tightness (CTA quality) genuinely require human judgment: they depend on context, relationship knowledge, and channel-specific conversion understanding that automated systems handle poorly.
The same checks apply, and if anything they’re more important in co-written content because the blended authorship can produce subtle inconsistencies in voice and tone. The human contributions and AI contributions can pull in slightly different stylistic directions. The Relevance check should specifically look for internal consistency: does the whole piece sound like it was written by one coherent voice, or are there detectable seams where the authors switched?
