10 Copywriting Mistakes That Kill Conversions (And How to Fix Them)
Most underperforming copy has the same problems. Not unique flaws — the same ten patterns showing up over and over again across landing pages, emails, ads, and sales pages. Here they are, with the fix for each one.
Mistake 1: Writing about yourself instead of the reader
"We are a team of passionate experts dedicated to helping businesses grow through innovative solutions."
Start with the reader's problem or desire. "You're spending 12 hours a week on reports that nobody reads. Here's how to get those 12 hours back." Every sentence should be filtered through: "What does this mean for the person reading?"
The reader's first question is never "Who are you?" It's "What does this do for me?" Copy that answers the first question before establishing the second has the structure backwards.
Mistake 2: Vague benefit claims
"Powerful results. Better outcomes. Transform your business."
Replace every vague claim with the most specific version of that claim you can prove. "47% reduction in reporting time" beats "saves time." "Clients closed $180,000 in 90 days" beats "drives revenue." Specificity is credibility. Vagueness signals that nothing specific happened.
Mistake 3: Listing features instead of benefits
"Real-time collaboration. Unlimited storage. 200+ integrations."
Translate every feature into what it means for the user: "Your whole team sees changes instantly — no more 'which version is this?' emails." Then go one layer deeper: "You stop being the one who manually reconciles files every Friday." The emotional consequence of the feature is the thing that actually sells. See how the FAB formula makes this translation systematic.
Mistake 4: A weak or missing headline
"Welcome to our website" or using the company name as the headline.
The headline's job is to make the right person stop and read. It needs a specific promise, a named audience, or an irresistible hook. "The project management tool that cuts your weekly meetings in half" beats "Project management software" in almost every test. Read how to write headlines that convert for the full framework.
Mistake 5: A confusing or missing call to action
Multiple CTAs competing for attention, or generic ones: "Click here," "Learn more," "Submit."
One primary CTA per piece of copy. Make it outcome-specific: "Get the free guide," "Start my trial," "See the 10-minute demo." The CTA should tell the reader exactly what they get when they click — not what they do. See the complete breakdown of CTA examples that convert for tested alternatives.
Mistake 6: Burying the lead
Three paragraphs of context and history before the reader knows why they should care.
Lead with the most important thing. If you're making a claim, make it in sentence one. If you're telling a story, start at the most interesting moment. Background and context can come after the reader is hooked. Journalists call this "burying the lead" — putting the news in paragraph four instead of paragraph one. Don't do it.
Mistake 7: Ignoring objections
Making the argument for the purchase without acknowledging why someone might not buy.
Every reader is holding objections. If you don't address them, the reader holds them privately and doesn't buy. Name the objections directly: "You might be thinking this is too expensive." Then answer it. Addressed objections lose their power. Ignored objections compound into doubt.
Mistake 8: No proof
Claims with no evidence: "The best solution on the market."
Every significant claim needs evidence: a testimonial, a statistic, a case study, a credential, or a demonstration. "The best" is unverifiable. "Used by 12,000 marketing teams at companies including [names]" is specific and verifiable. The more specific the proof, the more credible the claim. Proof is not decoration — it's the claim doing its job.
Mistake 9: Writing in passive voice and corporate language
"Synergistic solutions are leveraged to optimize workflows and drive stakeholder value."
Write the way you'd explain it to a smart friend. Active voice. Short sentences. No jargon unless your audience specifically uses it. Read your copy aloud — if you'd never say it in a normal conversation, rewrite it. The test: can you explain what this does to a ten-year-old? If not, it's not clear enough yet.
Mistake 10: Optimizing for the writer's satisfaction, not the reader's outcome
Clever wordplay, elaborate metaphors, and polished prose that impresses the writer but loses the reader.
Copy's job is to make the reader do something — not to make the writer look good. The goal is never to show how well you can write. The goal is to be understood, believed, and compelling. These are different objectives. Clear beats clever. Specific beats lyrical. Useful beats polished. Every time.
The single thread connecting all ten mistakes
Every mistake on this list comes from the same source: writing from the writer's perspective instead of the reader's. Vague claims, feature lists, buried leads, unaddressed objections, weak CTAs — all of these happen when the writer is focused on what they want to say instead of what the reader needs to hear.
The cure is also the same across all ten: before writing a word, get clear on who you're writing to, what they want, what they fear, what objections they'll raise, and what decision you need them to make. The copy that answers those questions clearly, in the reader's language, is the copy that converts.
Everything else is craft layered on top of that foundation. Read the complete guide to direct response copywriting for the full framework. And if you're at the beginning, copywriting for beginners covers where to build the foundation.
