Top 10 landing page mistakes to avoid
Landing page mistakes are hard for the owner to see, because the owner already knows what the page means. A simulated visitor reads it cold and shows the step where it stopped.
What are the most common landing page mistakes?
Landing page mistakes sit in one of four places: the headline and first button, the proof and the offer, the form and the reply, and the phone layout. The mistake a stranger meets first decides whether they read the rest, such as a headline that names a category instead of a result, or a button that says Submit. A simulated test runs a visitor through the page and shows the step where each mistake stopped them, with what they thought at that point.
What this looks like in a report
“Streamline your guest experience. Okay, but what does it do? There is a button that says Get started and a photo of people at a laptop. I still do not know if it takes bookings.”
The fix. Replace the headline with what the tool does for a named customer, such as taking table bookings from a website. Put a screenshot of the booking screen beside the button, and label the button Start a free trial.

Each mistake looks fine to the person who wrote the page
You wrote the page, so every line reads clearly to you. A stranger has none of that. They read the headline in a few seconds, scan for a price, and decide whether to keep going. Each of the ten mistakes below costs a visitor at one point in that order, so the one to fix is the one at the step where they stopped.
- The headline says what the product does, in words a buyer uses, and names who it is for.
- The main button names the next step in the visitor's terms, such as Start a free trial.
- The page shows the product itself, not a stock photo of people at laptops.
- The proof names what it proves, and the price or its starting point shows without a form.
The first screen: what it does, and what to press next
Mistake one is a headline that names a category instead of a result. Streamline your workflow could describe any tool, so a stranger cannot tell whether it is for them. The right version names the result for a named customer, such as taking table bookings from your website without a phone call. Mistake two is a button that says Submit or Learn more. A visitor who is ready to try the product does not know what Submit gives them, so they hesitate. Write the button as the visitor's next action, such as Start a free trial, and say what happens after it in the line beneath.
Mistake three is a stock photo of people smiling at a laptop, placed where the product should be. It tells the visitor nothing about what the screen does. Replace it with a screenshot of the real screen a customer will use, cropped to the part that matters, such as the booking list. A visitor who sees the screen can say what it does in their own words, which is the sentence the headline failed to give them.
Proof and offer: what a visitor checks before they trust you
Mistake four is a claim with nothing under it, such as Works for every team or Built for the way you work. A stranger reads those as filler, because any product could write them. Name the proof you actually have: a specific use, a customer who runs the same kind of business, or the exact feature that solves the problem in the headline. Mistake five is the missing price. A visitor who cannot see a starting point will not know whether a form is worth their time, and some leave without saying so.
Mistake six is two offers on one page: book a demo in one corner and start a free trial in the hero. The visitor has to choose between them before they know what the product does, so the visitor may pick neither. Keep one primary action on the first screen, and move the demo to a line lower down for buyers who want a person first.
The form and the reply: what a visitor gives you, and what they get back
Mistake seven is a form that asks for everything before it gives anything: a phone number, company size, role and budget. A visitor who only wants to see the product leaves rather than fill in six fields. Mistake eight is an error message that names nothing. Please check your details tells a stranger something is wrong, but not which field, so they retype everything. Name the field and the reason beside it.
Mistake nine is a reply with no next step. The page says thanks after the form, and the visitor is not told who writes next, whether to check an inbox, or what to do in the meantime. A visitor with no answer to those questions assumes nothing happened, and may send the form again. Say who writes next and when, and give them one thing to do now, such as reading the first guide the product sends.
The phone: the button that falls below the fold
Mistake ten is the one you will not see on your own laptop. On a phone the first screen is shorter than the one you designed, and the button that sat above the fold now sits under the headline, the photo and a cookie banner. A sticky bar at the bottom can cover the same button when the keyboard opens. Open the page on a phone, count the scrolls it takes to reach the main button, and fix the layout before you rewrite the copy. A visitor who cannot reach the button never reads the headline you rewrote.
What you get with Mimiq
- 01
Run it by hand, or on every pull request
Paste a link and a task in the app and watch the visitors work. Or run them on every preview deploy: the GitHub Action comments on the pull request, any other CI can call the MCP endpoint, and your coding agent can run it too.
- 02
Bugs and usability problems in one report
The browser records errors and failed or slow requests on the step they happened. The visitors say where the wording or the steps confused them, and where they left.
- 03
Visitors that behave like your audience
Each visitor is a different profile with a reason to be there, matched to who the page is for, described by you, or built from your own customers.
- 04
A prompt to fix each problem
Every problem comes with a fix to paste into Cursor, Claude Code, Lovable or any coding agent, and one prompt hands over the top problems at once. Then send the same visitors through again.
- 05
Follow every visitor
See each visitor's whole path, step by step with screenshots, and what it was thinking at every step. Ask any visitor a question.
The browser records relevant JavaScript errors and failed or slow app requests encountered during the run, attached to the step where they occurred. The visitors are simulated: they find problems, they do not predict how many real people will convert.
A new headline or a new hero image can bring a mistake back
Pages change in small edits: a new headline for a campaign, a new photo, a button label changed for a launch. Each edit can bring back a mistake you had already fixed. Rerun the same visitors after each edit, on a preview address, and read the step where each one stops.

Questions
Does every landing page make all ten mistakes?
No. A list tells you what to look for, but it does not tell you which mistake a stranger hits first on your page. Run the page, read the step where each visitor stopped, and fix that mistake before the rest.
Which mistake should I fix first?
The first one a visitor meets, because the later ones are never read if that one stops them. On many pages that is the headline or the first button, and on a phone it can be the button below the fold.
Can a simulated visitor tell me whether my headline works?
It can show whether a visitor understood the headline, from the thought they wrote at that step and the answer they gave when you asked them what the product does. It does not predict conversion, and it gives no rate for one headline over another.
Should I rewrite the whole page at once?
No. Change one mistake, run the same visitors again, and read whether they got further. Several changes at once make it impossible to tell which one helped, and a visitor who stopped early may now stop at a different place.
