How to launch new experiments on Fibr AI?

Fibr automatically generates top hypotheses for any live URL by analyzing page performance, visitor behavior, and page context. These hypotheses are converted into experiments and tested at scale.

Steps to create experimentation campaign on Fibr AI?

Ready to launch your first experiment? You'll go from URL to live test in just a few minutes. Here's how to generate hypotheses and set up your campaign.

Step 1: Start Your Hypothesis

Option 1: If you're a first-time user: Navigate to 'Experimentation' in your left sidebar, then click 'Get Started'

Option 2: If you've created hypotheses before: Navigate to 'Experimentation' in your left sidebar, then click 'Add New Page'

Step 2: Enter Your Page URL

Paste your website URL into the Hypothesis module. Fibr will automatically fetch your page structure, content, and visual elements to understand exactly what your visitors see.

Fibr AI generates hypotheses for the specific URL you enter, so make sure you're using the exact page you want to test.

Step 3: Choose Your Starting Point

After entering your URL, you'll see two options for creating hypotheses:

Type	When to Use	What Fibr Does
Generate Hypothesis (Recommended)	You want Fibr's AI to analyze your page and surface optimization opportunities automatically	Fibr scans your layout, copy, and metrics, then generates data-backed hypotheses tailored to your business goals
I Already Have My Hypothesis	You've already identified what you want to test from previous analysis or insights	Fibr skips generation and takes you directly to variant setup and tracking configuration

If you already know what you want to test, Option 2 gets you to experiment setup faster.

Step 4: Fill the campaign details

Give your hypothesis a clear, descriptive name and choose the goal you want to optimize (like Lead Submitted, Add to Cart, or Start Free Trial).

We Recommend Connecting Google Analytics (GA4)

Toggle on "Connect Google Analytics" to unlock more accurate, data-driven hypotheses. When connected, Fibr will:

• Analyze real user behavior (scroll depth, time on page, bounce rate, and more)

• Leverage audience insights to make recommendations that match your actual traffic patterns

Integrate Google Analytics (GA4)

Step 5: Add Page Context

Before generating hypotheses, Fibr needs a bit of context about your page and audience to make its suggestions spot-on.

• Review Key Benefits: Fibr automatically detects and pre-fills your main value propositions. Check that they're accurate.

• Define Your Target Audience: Select the audience segment this page is designed for.

• Add Common Customer Objections: Help Fibr optimize your content by sharing what concerns or hesitations your customers typically have.

Once you've reviewed or adjusted these inputs, click Generate Hypothesis.

Step 6: Review Your Hypotheses

Fibr will analyze your page, highlight what's working and what's not, and present you with the top data-backed hypotheses.

Each hypothesis includes:

• What element to change (text, visuals, or layout)

• Why it matters for your conversion goals

• The expected impact on performance

You're ready to convert any of these directly into an experiment.

Step 7: Select Hypotheses to Test

Click Test Hypothesis to choose which hypotheses you want to run. Fibr lets you select your top picks based on potential impact and your testing priorities.

Once you've confirmed your selections, click Create Experiment.

Step 8: Review and Publish Your Campaign

Fibr automatically creates an experiment with each hypothesis as a separate variant. Traffic is split uniformly across all variants by default, but you can adjust the allocation based on your needs.

Important: Make sure your total traffic allocation always adds up to 100%.

Next, add your Primary Metric to track. This is how you'll measure which variant wins (e.g., conversion rate, click-through rate, or form submissions).

Review everything one last time, then click Publish to make your campaign live.

Congratulations! Your experiment is now running. Fibr will track performance and let you know when you have statistically significant results.
