A/B Testing

A/B Testing allows you to manually split your traffic between different variants of your landing page. This gives you full control over traffic distribution to test which page design or content performs better against your conversions.

How Does A/B Testing Work?

A/B testing involves selecting a single element to test, creating a control version and a modified variation, randomly assigning visitors to each version, and collecting data on their interactions.

Statistical analysis of the collected data reveals which version is more effective in meeting the chosen goal.

A/B testing provides valuable insights into user behavior and allows for informed decision-making to enhance content performance and achieve desired outcomes.

Steps to Activate A/B Testing

  1. Navigate to the Landing Page: From your dashboard, click on the specific landing page you want to configure for A/B testing (00:03–00:04).
  2. Locate the Variant Mode Selector: On the page’s Overview tab, find the Standard Mode dropdown under the Variants section (00:07–00:08).
  3. Select A/B Test: Click the dropdown and select A/B Test (00:08–00:09).
  4. Confirm the Switch: A confirmation pop-up titled “Switch to A/B Test Mode” will appear, explaining manual traffic control between variants (00:10).
  5. Finalize Activation: Click “Switch to A/B Test Mode” to complete activation (00:11).

After publishing, LanderLab will send equal traffic to all active variants and display results under analytics. Ensure conversion tracking is enabled for meaningful test results.

Creating Landing Page Variants for A/B Testing

Once A/B Testing Mode is active, you’ll need at least one additional variant to test against your original page. You can do this by either duplicating an existing variant or importing another landing page.

Method 1: Duplicate an Existing Variant

  1. Access the Variants: On the landing page Overview screen, find the list of existing variants.
  2. Click Add Variant: Click + Add Variant above the variant list.
  3. Select Duplication Type: Choose “Duplicate an existing variant.”
  4. Name the New Variant: Enter a Variant Name (e.g., “Variant B”).
  5. Choose the Source Variant: Use the dropdown to select the variant to copy (e.g., “Variant A”).
  6. Finalize Creation: Click Add Variant to finish.

Method 2: Duplicate Another Landing Page Variant

  1. Access the Variants: On the landing page Overview screen, locate the variant section.
  2. Click Add Variant: Click + Add Variant above the variants list.
  3. Select Duplication Type: Choose “Duplicate another landing page.”
  4. Select Landing Page to Copy: A window will display all available pages in your workspace.
  5. Choose and Apply: Select the desired source page and click Apply.
  6. Name the New Variant: Enter a name for the new page (e.g., “Variant C”).
  7. Finalize Creation: Click Add Variant to complete.

Managing Traffic Weights for A/B Testing

  1. Access Variant Weights: On the landing page Overview screen, find your list of active variants.
  2. Click Manage Weights: Opens the Variant Weights configuration window.
  3. Manually Adjust Weights: Enter the desired Weight (traffic percentage) for each variant.
    • 50/50 Split: Set both variants to equal values (e.g., 100 / 100).
    • Even Split (3 Variants): Set all to 100 for 33.3% each.
    • Custom Ratio: Example: A = 300, B = 100, C = 100 (60/20/20).
  4. Spread Equally: Click this option to automatically distribute traffic evenly.
  5. Save Changes: Click Update Weights to apply changes.

How to Change A/B Test Master Variant

  1. Navigate to the Landing Page: From your dashboard, click on the page being tested.
  2. Locate Variants: On the Overview tab, view your active variants. The current main variant is labeled MAIN.
  3. Open Options Menu: Find the new winning variant (e.g., Variant C) and click the three-dot menu (•••).
  4. Set as Main: Select “Set as Main.”
  5. Traffic Confirmation: Once confirmed, traffic will fully shift to the new main variant in Standard Mode.

Important Notes

Standard Mode: After testing, switch back to Standard Mode so that the chosen Main Variant receives 100% of the traffic.

Traffic Allocation: Assigning a new Main Variant ensures the highest-performing design or message continues receiving all incoming traffic.
