How to test your website before launch
A practical pre-launch check: the technical basics, the first impression on laptop and phone, and getting feedback from strangers before real visitors arrive.
Updated October 1, 2026
Before a website goes live, test three things: that it works, that the first screen makes sense to a stranger, and that it looks right on a phone. Fixing a confusing headline before launch costs a few minutes. Finding out after launch costs the visitors who already left.
This guide gives you a checklist for each, in the order that saves the most time.
1. The technical basics
Broken things undo everything else. Check these first:
- Every page loads, including the 404 page, and no links lead to errors
- Forms work and the messages actually arrive where they should
- A secure connection (https) everywhere, without browser warnings
- Loading speed: the first screen appears quickly on a phone with an average connection
- Titles and descriptions are filled in for each page, so search results look right
- Analytics is installed, so you can see what happens after launch
2. The first screen
Visitors decide on the first screen whether to stay. Go through the four questions of the first impression checklist:
- Do I understand what this is? Does the headline say what you offer?
- Do I trust it? Is there at least one trust signal in sight?
- Does it look professional? Nothing broken, no placeholder text left behind, no cookie banner covering everything?
- Would I stay? Is there one clear next step?
3. The phone
Most visitors will see your site on a phone first. Check the first screen there separately: things that sit side by side on a laptop end up stacked on a phone, and the main button often drops below the first screen. The mobile first screen guide goes into detail. The free above the fold checker shows both screens side by side.
4. Feedback from strangers
After weeks of building, you can no longer see your website the way a first-time visitor does. You know what every word means and where everything is. That's exactly why feedback from strangers is the most valuable test before launch.
- Don't ask only friends or colleagues. They know you and they want to be supportive.
- Ask the same questions every time, so you can compare answers and see a pattern.
- Test the first screen, not the whole site. That's where most visitors decide.
On StayOrBounce, real people rate your homepage on the four questions within days, and the site doesn't have to be public yet: a hidden address that isn't linked anywhere works. Change what scores low, retake the screenshots and test again to see whether it helped.
