Landing page checklist: check it as a stranger
You know your page too well to see it the way a stranger does. This list follows the order a stranger meets the page, and a simulated visitor can run that order before the page goes live.
What should I check on a landing page before it goes live?
Check it in the order a stranger meets it: the link that brings them, the first screen on a phone, the one action the page exists for, the form, and the confirmation after it. Use a fresh browser you have never logged into, on a connection outside your office network, so cookies and cached files do not hide the faults. A simulated test runs the same order from a public address and shows the step where each visitor stops.
What this looks like in a report
“The page says it is a studio booking tool, not a photo tool. The form wants a business name and a tax number. I do not have a tax number on hand. I will ask my friend first.”
The fix. Move the tax number field into the step after sign-up and mark it optional, then add one line above the form naming who the tool is for. Test the form on a phone with an empty field, then a valid entry, and check that each error names its field.
An illustration. Run a test to see your own.See a real sample report
Your own browser hides the faults a stranger meets
The owner of a page has a logged-in browser, cookies from every test, cached images and a memory of what each button does. None of that is available to a stranger who clicked a link a friend sent. The owner scrolls past the cookie banner without reading it, knows where the menu opens, and fills the form with an address they already use. A checklist run from the owner's seat passes items that fail for a stranger. To see what the stranger sees, clear that context and start from the link.
- Address: does the link reach the page directly, with no redirect loop or login wall?
- First screen on a phone: is the product named, and is the main button above the fold?
- Cookie banner: does it cover the button, and does closing it keep the page usable?
- Form: does each error name its field, and does the page keep what the visitor typed?
- Thank-you step: does it say what happens next, and does the email link to the live domain?
How it works
- 01
Open the link from outside your own browser
Start from the address a stranger would use, in a fresh private window on a phone. Do not start from a saved bookmark, since a bookmark can skip the redirects the real link uses.
- 02
Read the first screen without scrolling
Write down what the page sells, who it is for and what to do next, using only what is visible. If you cannot say all three, a stranger probably cannot either.
- 03
Walk the one action the page exists for
Press the main button and follow it to the end. Note each field, each error message and each step, and whether the next page names what the visitor just did.
- 04
Break the form on purpose
Submit it empty, then with a wrong email, then with a valid entry. Check that each error names its field, and that the confirmation email reaches the inbox the visitor gave.
Start from the link, not the homepage
Owners tend to test from the homepage. A stranger usually starts from a link: a post, an ad, a message from a friend or a directory listing. That link can carry a redirect, a tracking parameter or a different path into the site. Click it from a fresh session and note every address the browser passes through before it lands. If the link's redirect drops a parameter, the page may show a generic first screen. That is a fault you will never see from the homepage.
The preview card is the first thing a stranger sees
Before anyone clicks, a link often appears as a small card in a chat, a feed or a message. The card's title, description and image come from the page's meta tags, and an empty or default value becomes the first impression. Paste the address into a chat with yourself and read the card the way a stranger would. Check that the title names the product, the description says who it is for, and the image is not an old banner. A card that reads Untitled tells a stranger the page is unfinished, even when the page works.
Check the page again after every change, not only before launch
Landing pages change after launch: a new banner, a booking widget, a chat box or a rewritten headline. Each change can cover the action the page exists for, and the owner rarely notices, because they already know where the button is. Run the four steps again after each change, on a fresh session, and compare where the stranger stops with the last run. A checklist kept in a document and run once before launch is how a banner ends up sitting on the button for a month.
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 banner or form update can cover the button a stranger needs
Landing pages keep changing after launch: a new banner, a booking widget, a chat box, a rewritten headline. Each one can cover the action the page exists for, and the owner rarely sees it, because they know where the button is. Run the same stranger path after every change, on a fresh session, and compare where it stops. Test any page behind a login with a test account, and check it again before a new traffic source starts.

Questions
Do I need a checklist if I already test my page?
Yes, if your tests run from the owner's seat. A checklist changes the starting point: a fresh browser, the public link and the first screen read without scrolling. A test from your own logged-in browser passes whenever that browser already knows the answer, such as where the menu is.
How often should I run the checklist?
Before the page goes live, after each change to the first screen, the form or the link, and after each change to a tool on the page, such as a booking widget or the analytics snippet. A change to one footer image does not need a full run.
Which checks can a simulated test cover?
The path checks: the link, the first screen, the one action, the form and the confirmation. It does not check whether your claims are true or allowed, whether the offer is right, or whether the copy will persuade anyone. It cannot tell you whether the page gets the traffic you need.
What can a simulated visitor not tell me?
It does not predict how many visitors sign up, and it cannot pay with a real card or sign in with Google. A CAPTCHA can stop it. It shows where a visitor stopped and what they read at that step, with a screenshot.
Can the checklist replace a review by real people?
No. It checks the path and the wording a visitor meets, but a person who has never seen your product can read the same words differently than you expected. Two or three people who have never seen the page, reading the first screen aloud while you listen, will show you wording a checklist cannot.
