With PBX, building a b tests has become so easy that knowing what to test has become your real advantage. Because no matter the size of your company, your traffic is still a limited resource and you can't test everything. That's why we're so excited to partner with Conversion by Gain, the leading experimentation agency to introduce test ideation as part of PBX. So let's take a look at how it works. So to start, you'll just provide your page's URL to have it scanned. After a few minutes, your hypotheses will be ready for your review. You'll see a summary of the hypothesis as well as its corresponding test idea. Our AI agent has scored each test idea and flags the one that's most likely to drive measurable impact. You can read more about the insights backing each hypothesis. Test ideation is using learnings from over twenty zero experiments to find the ideas that are most likely to win. In fact, our test ideas are up to three times more likely to produce a positive result than the industry benchmark. Now down here, you'll see the recommended test idea, and it further breaks down into the variations that you can create to validate or invalidate this hypothesis. Choose the one that you'd like to move forward with, and you can just pick the high priority ideas and build them instantly with PBX. You don't even need to write a prompt. It's already done for you. All you need to do is hit submit. It's that easy to go from idea to launching a test in just a few clicks. Test ideation is the first set of AI agents that mimics a CRO expert by scanning your pages and recommending tests based on a rigorous framework and deep contextual insights, resulting in a b tests that are three times more likely to succeed. If you wanna be among the first to try it, join our wait list today.

Driving upsell with goal proximity gamification for Adidas

UX optimisation
Gamification

by

Baveux Alexandre

This initiative leverages gamification by applying the Goal Proximity effect through an upsell mechanic designed to help users reach the next tier of the loyalty program. By clearly displaying the simulated progress toward the next loyalty level directly within the cart, the experience aimed to motivate completion, increase perceived value, and encourage users to add more items to reach the next milestone.

Reducing scroll to improve checkout progression for Puy du Fou

UX optimisation

by

Mathieu Azzopardi

This change aimed to reduce exits by minimizing scrolling on the order summary page. Key information was grouped into a single visible block, while cart details were moved into an optional accordion. By improving clarity and focus at this step, the experience encouraged smoother progression to the next stage of the checkout flow.

Compare mode for outdoor clothing in the The North Face shop

Product Visualisation

by

Samuel Sailer

Everyone knows product comparison by now. However, it is quite underutilized in fashion, especially in branches where products also have a functional purpose—like outdoor products, for example. As a user, I want a quick and easy way to compare jackets with regard to attributes such as waterproofing, insulation, wind resistance, etc.

Bringing social proof to the top of the page for Promovacances

UX optimisation

by

Pierre M

User reviews play a key role in the decision-making process and, when positive, significantly strengthen product credibility. Previously placed at the bottom of the page, they required extensive scrolling, limiting their visibility and impact. By moving user reviews to the top of the page, the objective was to surface social proof earlier in the journey and increase add-to-cart intent through the “Book” buttons located further down the page.

FAQ

Entscheidet Prompt-Based Experimentation, was getestet wird?

Du kannst PBX nach Optimierungsideen fragen und dann selbst entscheiden, welche du umsetzen möchtest – oder dir einfach neue Vorschläge geben lassen. Je konkreter du dein Ziel formulierst, desto besser werden die Ideen, die PBX für dich entwickelt.

Is PBX vibe experimentation?

Just like vibe coding lets you create web prototypes instantly by chatting with AI, PBX lets you create new and optimized web product on your existing websites.  You get to test what you've created on real users on your actual website. The act of building variants and testing them by chatting with AI is called vibe experimentation.

Was ist ein „Credit“ – und wann wird er verbraucht?

Jedes Mal, wenn du einen Prompt verwendest, wird ein Credit verbraucht. Deine kostenlose Testphase enthält genügend Credits, um alle wichtigen Funktionen auszuprobieren. Wenn du einen Promo-Code für zusätzliche Credits hast, kannst du ihn auf der Seite „Organization“ in deinem Account eingeben. Im Durchschnitt benötigen unsere User etwa drei Credits, um ein Experiment zu erstellen. Bei Fragen kannst du dich jederzeit an contact@kameleoon.com wenden.

Was genau ist Prompt-Based Experimentation (PBX) – und wie funktioniert das Ganze?

Prompt-Based Experimentation (PBX) ist Kameleoons Ansatz für Vibe Experimentation – ein neuer Weg, um Experimente zu entwickeln, zu konfigurieren und zu starten. Mit PBX beschreibst du einfach in natürlicher Sprache, welche Änderungen du auf deiner Website testen möchtest. Die KI erstellt daraufhin automatisch eine Variante und startet das Experiment – ganz ohne Code oder WYSIWYG-Editor.
