Some words in marketing don't just fail to help — they actively signal that you're not worth listening to. They're the verbal equivalent of a limp handshake: technically present, but conveying nothing useful.
Here's the conversion-killing blacklist, and the replacements that actually work.
"Check out our latest blog post"
Why it fails: It sounds like homework. Nobody wakes up wanting to "check out" anything. The phrase signals low stakes and no specific value.
What to write instead: "The three-minute read that doubled my email open rates" or "How one sentence change generated an extra $4,000 in a single campaign." Tell them what they get, not what you're offering.
"Solutions for all your needs"
Why it fails: It says nothing. "All your needs" is every product's claim and therefore no product's claim. It signals that you haven't thought carefully about who you're talking to.
What to write instead: Name the specific problem and the specific outcome. "Stop losing subscribers in the first 24 hours" or "Turn one-time buyers into customers who come back every month."
"We're passionate about helping our customers"
Why it fails: Passion is the cheapest thing you can claim. If you have to announce it, you're not showing it. Customers aren't buying your feelings — they're buying outcomes.
What to write instead: Describe the problem you hate watching people have, and what you built to fix it. "Watching good products fail because of bad copy is the problem we exist to solve" says more than any passion claim.
"Innovative solutions"
Why it fails: Every company claims innovation. The word is so overused it functions as a filler, occupying space where a specific, credible claim could live.
What to write instead: Describe what you actually changed and why it matters. "The first email tool that tells you which subscribers are about to churn, before they do" is a claim. "Innovative solutions for email marketers" is not.
The underlying principle
Every word in your marketing competes for a specific amount of the reader's attention. Vague, generic, or self-congratulatory language wastes that attention. Specific, outcome-focused, problem-aware language earns it. The test is simple: could your competitor say the exact same thing about their business? If yes, you haven't said anything. Say something only you can say.
