A good landing page has one goal and one audience. We build it with AI in hours, check every sentence and pit variants against each other. The page only goes live once you approve it.
Example test: same ad, two pages, one metric.
A landing page is where someone arrives after clicking an ad. It has exactly one goal, usually an inquiry or a purchase. If the ad just goes to the home page, visitors have to hunt around on their own and often leave.
Every new page used to take weeks, so testing was rare. With AI, a draft and variants take hours. That changes the work, because you can now try several ideas instead of betting on one.
The same goes for entire websites. We built this site that way and run it ourselves.
Someone clicks on a specific offer and lands on a generic home page. The interest you paid for fizzles out.
Brief, agency, rounds of revisions. By the time the page is done, the campaign is over and nothing has been tested.
On desktop, everything looks good. On the go, the page loads slowly and the form is a chore.
One offer, one audience, one next step. Copy, design and form are created as one.
A different headline, a different opening, a different form. The variants run against each other and the results decide.
Complete company websites with a clear structure, a fast build and content that also works in search.
We look at where visitors drop off. Then we change exactly what is holding them back.
We check every page on mobile first. Load time and usability are part of sign-off.
Every page reports inquiries back to analytics and ad accounts. So testing starts the moment the page goes live.
Hours instead of weeks works because the AI handles the grunt work and nobody has to wait for the next meeting. In the end, speed also depends on how quickly you approve.

The page goes live and competes against the next variant
What do you sell, to whom, and what should people do on the page?
The AI delivers copy and variants in your brand voice. We trim and correct them, then build the page.
You see the finished page at a preview URL. It only goes live once you say yes.
The test can start the same day. The better variant stays and competes against the next one.

We work with your colors, fonts and wording. If you have a design system in place, we build on it. If you don’t have one yet, we develop a lean foundation with you.
That depends on scope, content and test plan. Working with AI makes the build itself much shorter than it used to be. Once we know your offer and your audience, you get a fixed quote up front.
With a clear brief and existing images, it can be done in hours, plus the time for your approval. Legally sensitive topics or many stakeholders take longer.
Unchecked, yes. That’s why decisions on copy and design stay with us and you. The AI takes the grunt work off our hands and gives us more variants to choose from.
That depends on your needs. We often build individual landing pages as fast static pages, but can also use your existing system on request. Either way, you keep access.
We add the required pages and set up the form properly on the technical side. You or your legal advisor provide the text.
Conversion optimization means improving a page so more visitors take the desired step, such as sending an inquiry. We rely on measurement and tests, not guesswork.
