The landing page copy checklist to run before you launch

1. One page, one reader

Before you check a single line, decide who the page is for. Copy written for two audiences converts neither, because each waits for the sentence addressed to them and leaves before it lands. ScreenshotOne's hero addressed developers and AI-agent builders in one breath and stated no problem at all.

“Give your AI agents eyes for the web. The screenshot API for developers.”ScreenshotOne — teardown verdict: two audiences, zero problem named

The rewrite picked the developer and the actual pain: “Screenshot API that renders at scale without managing browsers.” If your product genuinely serves two buyers, that is a second page or a section below the fold — never the hero.

2. Headline sells the outcome, not the category

“The screenshot API for developers” says what the company is. It does not say what changes for the reader. Category lines are fine on a business card; in a hero they answer a question nobody asked. Read only your headline and ask “what is in it for me?” — if the answer requires already knowing what the product does, the headline fails the 3-second scan.

3. Mechanism comes after stakes, never before

Founders buy outcomes; implementation detail belongs behind them.

“StatusFlo auto-detects Stripe outages by watching your payment webhooks — then notifies customers via email and updates a custom status page.”StatusFlo — teardown verdict: mechanism ahead of outcome

The buyer's fear was hearing about a failed checkout from an angry customer. That fear was invisible until the rewrite put it in the headline: “Stop Hearing About Stripe Outages From Angry Customers.” The webhooks moved to the subhead, where mechanism earns trust instead of consuming the first scan.

4. Every number is anchored

Unattributed percentages read as marketing theater to a buyer deciding whether to trust you. InvoTools leaned on exactly that proof.

“25% increase in customer retention. 40% boost in post-purchase engagement. 60% reduction in paper waste.”InvoTools — teardown verdict: no customer, timeframe, or source

Volume without outcome is filler. ScreenshotOne had real traction — 3,700+ developers — but sat it next to “proudly serving companies from small to large”, which is the sound of no claim at all. Anchor each number to a named customer, a timeframe, or a source, or cut it.

5. One primary call to action

Count the distinct actions on your screen. InvoTools had seven — Watch Demo, Request a Demo, Know More, READ MORE, Learn More, See the Problem, Start the Conversation — with no hierarchy. When every action is offered, the next step is a multiple-choice exam, and ambiguity is where a demo request quietly dies. Pick one primary CTA; demote everything else to a text link.

6. The CTA commits to something specific

“Get Started” commits to nothing. The strongest CTAs in our teardowns name the action and the cost or the payoff: “List My AI Business — from $19”, “Get Every Playbook — $28/mo”, “Start rendering free”. Hiding the price until the signup form is a small leak that compounds: the visitors who would have converted bounce at the surprise and do not come back to tell you.

7. The page does not open defensively

One real page opened with “No motivation. No filler.” Leading with a competitor's sins primes doubt before a single promise lands — the page starts by arguing instead of selling. Lead with the promise; save the contrast for readers who are already comparing you, further down.

8. Your buyer's vocabulary, not yours

“Feature request prioritization” is roadmap vocabulary. Customers say “I keep building things nobody uses.” List the words your buyers type into a search box or say on a support call; your hero uses theirs, not your product's taxonomy. This is also an SEO check — you cannot rank for words your buyers never type.

9. No line needs a second read

Wordplay costs clarity exactly when readers are scanning fastest. “Know before your customers do” hides the object: know what? A visitor scanning in 3 seconds gets no product, no problem, no stakes. Cleverness is a bonus, never the payload; if the line needs a second read, most readers simply will not give it one.

10. Proof outlives the scroll

The hero earns the scroll; the proof section earns the signup. By launch day you need at least one anchor a stranger can verify — a named customer, a screenshot of real output, a public number. “Loved by teams of all sizes” is not proof. If you have no proof yet, borrow specificity: state the exact promise, the exact price, and the exact time-to-value, which is proof of the offer even before it is proof of the outcome.

What no checklist fixes

Copy is not a rescue for the wrong offer. If visitors match your buyer description, all ten checks come back clean, and still nobody signs up, the problem is usually upstream: the page promises something the product does not yet deliver, or the product solves a problem people do not pay to solve. No headline saves that, and any guide that tells you otherwise is selling you a rewrite.

Run it in 30 minutes

Print your hero — headline, subhead, CTA, nothing else. Apply the ten checks in order and write one sentence each. The first check that fails is usually your biggest leak, because everything below a broken headline is read by almost nobody. To see what a finished diagnosis looks like, read one of the 24 real teardowns — each shows the hero as it was, the three leaks found, and the rewrite.

Or skip the manual pass: paste your landing page URL into Copy Engine and get 3 conversion leaks free in about 30 seconds. The full rewrite costs $9.
