In short: a page looks vibe coded when nothing on it could only have been written by you. The gradient and the three feature cards are the part people name, but they are not what makes a visitor leave. Generic copy, proof that is decoration, a product you cannot see and template text nobody replaced do that. Fix those first: one sentence only you could write, the real product on screen, one proof a stranger can check, and every leftover placeholder gone. Then, if you still have time, change one thing about the look.
"Vibe coded" has become shorthand for a page that was generated rather than made: the same hero, the same cards, the same voice as a thousand other launches that week. It is not an insult about the tools. Most good pages now start from a template or a model. It is a judgement about care, and visitors make it fast. Nielsen Norman Group lists design quality among the four ways a site communicates trustworthiness, alongside "up-front disclosure, comprehensive and current content, and connection to the rest of the web" (Aurora Harley, *Trustworthiness in Web Design: 4 Credibility Factors*). A page that looks like nobody finished it fails the first of those, and usually the other three with it.
What makes a page read as generated?
Visitors rarely say "this is a template". They say it feels off, or empty, or like a scam. When you trace that feeling back, it is almost always one of five things.
1. The copy could describe any product. "Unlock your potential." "Supercharge your workflow." "The all-in-one platform for modern teams." These are the sentences a model writes when it has not been told anything specific, and readers have seen them on every launch board. The Plain words test (C3) fails "seamless", "powerful", "AI-driven" and "next-gen" on sight, because each one is an adjective doing the work of a fact.
2. The audience is everyone. "For teams and individuals", "for creators", "for anyone who wants to grow". A page for everyone is a page nobody feels was written for them. The Named test (A1) asks whether the reader can tell who it is for, and the Their words test (A2) asks whether the copy uses that person's words for their problem, not yours for the solution.
3. The proof is decoration. A row of logos that turn out to be the tech stack. Five stars with no source. Three testimonials from "Sarah K.", "Mike R." and "Priya S.", with no faces, no companies and no links. "Trusted by 10,000+ makers" on a product that launched on Tuesday. These are the blocks a template ships with, and visitors have learned to read them as filler.
4. The product is not on the page. An abstract 3D shape, a stock illustration, a phone mockup with a blurred screen. If the hero image could belong to any product, the visitor learns nothing about yours. The visible product test (P3) asks for the actual interface, not an illustration of it.
5. The template is still showing. "Your Company Inc." in the footer. A copyright year that is already over. Links to Twitter, GitHub and Discord that go to the template author or to #. A "Blog" link to an empty page, a pricing tier called "Enterprise" with a "Contact us" button that opens nothing. Each one alone is small. Together they tell the visitor that no one has read the page from top to bottom, which is the one thing a buyer needs to believe before paying.
Which of these costs you the most?
Proof. On the public pages graded so far, the Specific test (P2), which asks for names, numbers and dates rather than "loved by makers", is the one launches miss most among the four Proof tests. As of 25 October 2026, of 35 public launches judged on it, 17 passed, 4 passed in part and 14 failed. By contrast, P3 was passed by 31 of the same 35 and P4 Honest for the stage by 31. Most founders do show the product. What they leave as template filler is the evidence around it.
Plain words, oddly, is rarely the problem on the record: C3 was passed by 30 of 35. The generic feel tends to come less from a single bad headline than from the sections below it, where the template's sample copy was lightly edited instead of replaced. These are small samples from the public record, not a survey of the web, and each test page shows the real pages behind the numbers.
Or let the grader read it
Run all 18 tests on your page.
Paste your address. You get a score, a grade and the fixes in two to five minutes. Free, no card.
How do you fix it before launch?
In this order, because each step is cheaper than the next and does more.
Write one sentence only you could write. Put it in the hero or straight under it. It names who it is for, what changes for them, and something specific about how: "Turns your Stripe payouts into a tax-ready spreadsheet for UK sole traders, every month, without a login to your bank." Nobody else's product fits that sentence. If yours fits a competitor's page just as well, it is not specific yet.
Replace every template block's text, not just the headline. Go section by section and ask of each sentence: did I write this, or did it come with the page? Feature cards are the usual offender. "Lightning fast", "Secure by default", "Easy to use" can go. What does the feature let the buyer do, in their words?
Put the real product on screen. A screenshot of the thing working, with real-looking data, beats any illustration. A short screen recording beats a screenshot. If you sell a service, show a piece of the work: a sample deliverable, a before and after, a named client.
Keep one proof a stranger can check, and drop the rest. One named user with a link, one number with a date, a public changelog, a demo anyone can open. One specific proof does more than a wall of anonymous ones. If you have none yet, say what stage you are at. "Built by me, used by twelve people" is believable. "Trusted by thousands" on day one is the claim the P4 test exists to catch.
Sweep the leftovers. Search the page source for the template's name, "lorem", "example.com", "Acme", "Your Company" and last year's date. Click every link in the header and footer. Open the page on a phone, where template sections often break first.
Then, and only then, change one thing about the look. Not a redesign. One decision that is yours: a colour that is not the framework's default, a real photo instead of the stock one, a headline font that is not the one every starter kit ships with. The goal is not to look expensive. It is to look like someone chose.
What a grill can and cannot tell you here
None of the 18 tests in the rubric asks about colour, font or layout. A grill reads what the page says and what it shows: whether a stranger can tell what it is, who it is for, what it costs and why to believe it. That is deliberate. A stock template with specific copy tells a buyer what they need to decide; a beautiful page that says nothing does not, however long they look at it.
So if the page looks vibe coded, a grill will not say "change the gradient". It will point at the sentences that could belong to anyone and the proof that could not be checked, which is where the generic feel comes from. For the first-screen half of this, run the five-second test on a stranger. For everything else before launch day, the pre-launch checklist covers what to check.
The checklist
- One sentence in the hero that could only describe your product
- The audience named, in words they would use about their problem
- Every template sentence rewritten, section by section, not just the headline
- The real product on screen, not an illustration or a blurred mockup
- One proof a stranger can check, and nothing claimed the stage cannot support
- No placeholder text, dead social links, empty pages or last year's date
- Checked on a phone
- One visual choice that is yours, made last
