"Leverage our intelligent, seamless, next-generation platform to unlock transformative outcomes." Every word in this sentence has appeared on more than a thousand landing pages in the past year. None of them carries information. Together they tell the reader that the writer has something to hide behind impressive-sounding words. Jargon is not ambition — it's the signal that the writer couldn't think of a specific claim. This is the long version of PageLint check CL-6: No jargon in hero.
The Ogilvy ban
Ogilvy traced the specificity principle to Claude Hopkins, then stated it himself across both major books:
The best headlines are those that provoke curiosity, promise a benefit, or deliver news. Avoid tricky, gimmicky headlines. The reader wants information, not entertainment.
The principle behind the jargon ban isn't aesthetic — it's informational. Jargon words don't promise a benefit. They describe a product in a way the writer finds impressive, not in a way the reader finds useful. "Intelligent" is what the engineer calls the ML model. "Seamless" is what the product manager calls the UX. Neither word tells the buyer what changes for them.
Peep Laja at CXL distilled this into a rule: clarity beats persuasion. A clear claim that the reader can evaluate outperforms a persuasive-sounding claim they can't parse. Jargon eliminates the possibility of a clear claim.
The 18 banned words
PageLint's CL-6 check scans hero copy for these words:
Leverage — means "use." Use "use."
Synergize / synergy — means "work together." Say "work together."
Unlock — implies a barrier that doesn't exist. Name the actual benefit.
Transform — vague directional claim. What changes, specifically?
Revolutionize — unless you have verifiable evidence of category disruption, this is noise.
Disrupt — same as revolutionize. Claims disruption without demonstrating it.
Empower — means "let you do." Name what you let them do.
Seamless — means "it works." Every product claims seamlessness. Name the specific friction removed.
Intelligent — means "uses software logic." Every product claims intelligence. Name the output.
Robust — means "doesn't break much." Name the specific reliability metric.
World-class — unverifiable superlative. By what measure?
Leading — means "we think we're popular." Name the actual market position.
Best-in-class — same as world-class.
Next-gen / next-generation — every product in 2018 was next-gen. The word is now 20 years old.
Cutting-edge — same problem.
Innovative — if it were truly innovative, you'd describe the innovation specifically.
Game-changing — borrowed from sports coverage. Means nothing in a software context.
Paradigm — only acceptable in academic papers about Thomas Kuhn.
Jargon is the signal that the writer couldn't think of a specific claim.
What replaces jargon
Each jargon word has a specific claim hiding behind it. Find that claim.
Why jargon persists despite performing poorly
It feels safer. "Next-generation platform" doesn't make a claim that can be falsified. "Closes deals 23% faster" does. Founders are afraid of being held to specific claims.
It sounds like marketing. Jargon is what marketing sounds like in bad examples — and many founders learned copywriting from bad examples.
It's contagious. Competitor pages use it, so it seems like the category's language. It isn't. It's the category's noise floor. Rising above it requires naming what's actually different.
How PageLint detects this
CL-6 is a programmatic check. The parser runs a case-insensitive scan for the 18 banned words in the hero region. Match found → fail. No match → pass.
This is the simplest check in the Clarity lens and the fastest to run. It catches the most common failure mode — jargon substitution — without requiring LLM judgment.
Confidence: High. False positives are essentially zero for the banned list; these words have no legitimate use in hero copy.
Severity: Major. Jargon in the hero doesn't prevent comprehension the way a missing H1 does — but it signals low-credibility copy, which increases bounce.
