What is a Test/Variant Group
In Optibase, a test helps you figure out what works best on your website by comparing different versions of your content — called variants — and tracking which version leads to more conversions.
There are three main types of tests in Optibase:
A/B Tests (Variant Groups)
URL Split Tests
Multivariate Tests
Why it matters
Running tests lets you make data-informed decisions about your site design and content. Instead of guessing what works, you can test it — and improve conversions without blindly redesigning pages.
Test Types in Optibase
1. A/B Test (Variant Group)
An A/B Test, also called a Variant Group, is where you test one specific change.
You start with a base version (your control), then create one or more variants with a small change:
A different button color
New headline text
Swapped image or icon
Tweaked form layout
When visitors land on your site, each one is randomly shown one of the variants. Optibase tracks how each performs based on the conversion goal you set.
Example: You test a green “Buy Now” button vs. a blue one to see which drives more purchases.
2. URL Split Test
A URL Split Test lets you compare entirely different pages.
Each variant is a separate Webflow page (with its own URL), and you direct traffic between them to compare performance.
This is useful when:
Testing different layouts or flows
Comparing two landing pages
Validating a full-page redesign
Example: You test a long-form sales page vs. a short, punchy version to see which one converts better.
3. Multivariate Test
A Multivariate Test allows you to test multiple elements on the same page at once — for example, testing a headline, an image, and a button together.
Each element you want to test is placed in its own Variant Group, which works like a mini A/B Test.
Optibase then creates combinations of all possible variants and measures:
How each Variant Group performs on its own
How combinations of changes perform together
Example: Headline A + Button B + Image C vs. Headline B + Button A + Image C, etc.
This helps you understand not just individual changes, but how they interact.
Additional Testing Options
Optibase lets you control exactly who sees your tests by setting audience restrictions. You can limit exposure based on:
Location (Geo-Restriction)
Target visitors from specific countries or regions. Ideal for localized content or region-specific offers.
Screen Size
Restrict tests to certain viewport widths — for example, only users on mobile screens or large desktops. Helpful for responsive design changes.
Operating System
Show tests only to users on a specific OS like macOS, Windows, iOS, or Android. Great for testing platform-specific behavior or styling.
Browser
Limit tests to users on specific browsers such as Chrome, Safari, Firefox, or Edge. Useful when debugging or optimizing for browser quirks.
Example: Want to test a new layout for desktop users on macOS using Safari? You can target that exact audience.
These filters help you run more precise and relevant experiments — especially when testing features that behave differently across environments.
Tips for Success
Use A/B Tests for small, focused changes.
Use Split Tests when comparing entire layouts or flows.
Use Multivariate Tests when testing multiple elements at once — but keep combinations manageable.
Set clear conversion goals before starting a test.
Avoid testing too many things at once unless you have high traffic volume.
