Basics of A/B Testing in Visual Design

A/B testing in visual design is like a showdown between two webpage versions. You pit them against each other to see which one wins over your visitors.

Here's the gist:

Make two versions of a page
Show each to different visitor groups
See which one performs better

Why bother? It takes the guesswork out of design. Instead of relying on hunches, you get cold, hard data.

Take Yuppiechef, for example. They removed the menu from their landing page. The result? Their conversions DOUBLED from 3% to 6%. Small change, big impact.

What to Test

You can test pretty much anything visual. Here's a quick rundown:

Element	What to Try
Layout	One column or two?
Colors	Blue button or green?
Images	Product shots or lifestyle pics?
Typography	Serif or sans-serif?
Navigation	Horizontal or vertical menu?

Real-world wins:

An e-commerce site changed "add to bag" to "add to cart". Purchases jumped 81.4%.
Arenaturist tested vertical vs. horizontal search bars. Vertical won with 0.32% conversions vs. 0.23%.
Workzone tried colored logos in testimonials. Conversions up 34%.

Jeff Bezos, Amazon's founder, is all about testing:

"If you double the number of experiments you do per year, you're going to double your inventiveness."

No wonder Amazon runs thousands of A/B tests yearly. Every change is backed by data.

How to Do A/B Testing for Visual Design

A/B testing for visual design helps you make smart choices about your website's look. Here's how:

Set Clear Goals

Define what you want to achieve. Make it specific and measurable:

Goal	Metric
More conversions	Conversion rate
Better engagement	Time on page
Higher click-throughs	Click-through rate

Create Test Ideas

Think about changes that might boost performance:

"Red CTA button will get more clicks than green"
"Sign-up form above the fold will increase conversions"

Make Test Versions

Create two designs:

1. Control (A): Your current design

2. Variant (B): New design with ONE change

Only change one thing at a time. This way, you'll know exactly what worked.

Run the Tests

Use A/B testing software to show different versions to different groups. Tips:

Test for at least 2 weeks
Aim for statistical significance
Don't mess with the test while it's running

Check Results

After the test, dig into your data. Focus on your main goal metric to see which version won.

"A/B testing always tells you something." - Rebeka Costa, In-house SEO manager

Even "losing" tests teach you something for next time.

What to A/B Test in Visual Design

A/B testing can boost your e-commerce site's performance. Here's what to focus on:

Home Page Layouts

Your home page is crucial. Test these elements:

Hero images vs. carousels
Featured product placement
CTA button location

Fun fact: Only 1% of users click on carousel images. That's why Allbirds sticks to a single hero image on their homepage.

Product Page Designs

Product pages can make or break sales. Test these:

Element	Test Ideas
Images	Size, quantity, angles
Descriptions	Length, style, format
Reviews	Placement, layout
Related items	Number, arrangement

Swiss Gear's streamlined product page design? It boosted conversions by 52% overall and 137% during holidays.

Buy Buttons

Small tweaks, big impact:

Color: Red outperformed green by 21% in one test
Size: Bigger is better for mobile
Text: "Add to Cart" vs. "Buy Now"

WriteWork's CTA button tests led to a 144% jump in clickthroughs and 50% more sales.

Good navigation is key. Test:

Dropdown vs. mega menus
Sticky vs. standard nav
Category groupings

Yeppiechef doubled conversions by simplifying their menu.

Colors and Fonts

These shape your site's vibe:

Color schemes
Font sizes and styles
Line heights

Sonos nailed it with a minimal design, clean type, and lots of white space.

Advanced A/B Testing for Visual Design

A/B testing isn't just about comparing two versions. Let's dive into more complex methods to fine-tune your visual design testing.

Testing Multiple Changes

Multivariate testing lets you test several elements at once. Instead of just comparing button colors, you can test color, size, and text all together.

Here's the process:

1. Pick elements: Choose 2-4 page elements to test.

2. Create variations: Make different versions of each element.

3. Mix and match: Combine variations to create multiple page versions.

4. Run the test: Show different versions to user groups.

5. Analyze results: Find the winning combination.

Booking.com used this method to boost their search results page. They tested:

Search box position
Filter options layout
Sort order display

The result? A 2.8% conversion increase in just two weeks.

"Multivariate testing showed us how different elements work together. We found combinations we'd never have tried with simple A/B tests." - Stuart Frisby, Principal Designer at Booking.com

Smart Testing Methods

Bandit algorithms take A/B testing up a notch. They adjust traffic in real-time based on performance.

Here's how they're different:

Standard A/B Test	Bandit Algorithm
Fixed traffic split	Dynamic allocation
Set time period	Adapts as data comes in
May waste traffic	Shifts to winners
End-of-test results	Ongoing optimization

Intuit tested 24 TurboTax homepage versions using a bandit algorithm. They quickly spotted top performers and focused on the best designs. The result? A 6% bump in conversions.

To use smart testing:

Pick a bandit algorithm (e.g., epsilon-greedy, Thompson sampling)
Set up your platform to use the algorithm
Define success metrics
Launch and monitor
Let the algorithm do its thing

Understanding and Using A/B Test Results

Reading Test Data

A/B tests compare two design versions. Here's how to interpret the results:

Statistical significance: Look for 95% confidence or higher. This means your results likely aren't random.
Key metrics: Focus on conversion rate, CTR, time on page, and bounce rate.
Sample size: Make sure you have enough data. Too little can give unreliable results.
Secondary metrics: Don't ignore these. They can offer valuable insights into user behavior.

"A/B testing is about letting real data guide your decisions, not gut feelings." - Ryan Topps, Captchify founder

Making Design Choices from Data

After analyzing results, it's time to act:

Use winning variations: If B clearly beats A, consider using it site-wide.
Segment your results: Break down data by device, traffic source, and user demographics. You might find surprises, like a design working better on mobile than desktop.
Plan next tests: Use what you've learned to inform future experiments.
Consider practical impact: A statistically significant result might not always be worth the effort to implement.

Result	What to Do
Clear winner	Make the change
Not sure	Test longer or adjust
Surprise	Investigate why

Real example: Hotel site arenaturist.com tested vertical vs. horizontal forms. The vertical form got 52% more submissions, so they rolled it out everywhere.

Real A/B Test Examples in E-commerce Design

Let's dive into some e-commerce A/B tests that actually moved the needle:

Grene's Mini Cart Makeover

Grene tweaked their mini cart page:

Added a CTA button up top
Included 'remove' buttons for each item
Made the "Go To Cart" button bigger

The result? Conversions jumped from 1.83% to 1.96% in just over a month. Plus, they DOUBLED their total purchased quantity.

WorkZone's Black and White Move

WorkZone made ONE tiny change:

They switched their testimonial logos from color to black and white.

Sounds small, right? Well, it led to a 34% boost in demo requests in just 22 days.

Zalora's Free Returns Focus

Zalora decided to shout about their free returns policy on product pages.

The outcome? A 12.3% increase in checkout rates.

Ubisoft's 'Buy Now' Simplification

Ubisoft stripped down their 'For Honor' brand's 'Buy Now' page.

The result was impressive: conversions shot up from 38% to 50% over three months.

PayU's Field Removal

PayU took a "less is more" approach:

They removed the email address field from their checkout page.

This tiny tweak boosted conversions by 5.8%.

What Can We Learn?

Small changes can pack a punch (just look at WorkZone's logo color switch).
User experience matters (Grene's mini cart redesign proves this).
Simplicity wins (PayU and Ubisoft nailed this).
Test everything (product pages, checkout processes - it's all fair game).
Patience pays off (Ubisoft's three-month test shows good things come to those who wait).
Look beyond conversion rates (Grene's total purchase quantity tells a bigger story).

Remember: in e-commerce A/B testing, there's no such thing as a change too small to test. Every tweak could be the one that boosts your bottom line.
