Using A/B Tests to Improve Help Center Conversion Rates

Improving help center conversion rates isn’t about publishing more articles. It’s about learning what actually works for your users. That’s where A/B testing helps. Small changes—like a new headline, layout, or CTA—can impact how users search, read, and solve issues. For teams using Zendesk Guide, especially with optimized themes from Diziana, A/B tests make it easier to build a help center that people actually use.

What A/B Testing Means in a Help Center

A/B testing compares two versions of a page or element to see which performs better.

Version A is your current design.

Version B is a variation you want to test.

The goal is to improve:

  • Article engagement
  • Search success
  • Ticket deflection
  • User satisfaction

A good help center not only answers questions—it prevents confusion before it becomes a support ticket.

Why A/B Testing Matters for Support Teams

Help centers grow fast. Without testing, it’s hard to know what actually helps users. A/B tests reveal:

  • What users click first
  • What they ignore
  • What makes them bounce
  • What encourages self-service

According to Gartner, 70% of customers prefer self-service before contacting support. If your help center isn’t optimized, those users will jump straight to creating a ticket.

Diziana’s Zendesk themes make it easier to run meaningful tests because layouts are designed for clarity, structure, and conversion.

What to A/B Test in Your Help Center

1. Homepage Layout

Users decide within seconds if they can find what they need.

Test:

  • Prominent search bar vs. smaller search bar
  • Top articles vs. trending searches
  • Icon-based categories vs. text-only lists

Measure:

  • Bounce rate
  • Search usage
  • Ticket deflection

2. Search Bar Placement

Search is one of the most-used help center features.

Test:

  • Different placeholder text
  • Search suggestions on vs. off
  • Larger search bar vs. compact design

3. Article Titles

Clear titles get more clicks.

Example tests:

  • “Reset your password” vs. “How to reset your password”
  • Short titles vs. descriptive ones

4. Article Structure

Even great content performs poorly if it’s not easy to scan.

Test:

  • Step-by-step lists vs. paragraphs
  • Screenshots vs. no visuals
  • Short vs. long formats

Measure engagement, scroll depth, and “Was this helpful?” responses.

5. CTAs (Calls-to-Action)

CTAs guide users toward a next step.

Test:

  • “Contact Support” vs. “Still need help?”
  • Button vs. link
  • Placing recommendations above or below the article

6. Category Structure

Users often browse before they search.

Test:

  • Fewer categories
  • Renamed categories
  • Collapsible menus

How to Run A/B Tests the Right Way

1. Start With a Hypothesis

Example: “A larger search bar will increase search usage.”

2. Change Only One Thing

Too many changes = unclear results.

3. Split Traffic Evenly

Half of users see version A.

Half see version B.

4. Run the Test Long Enough

Most tests need at least 7–14 days.

5. Measure What Matters

Focus on:

  • Successful searches
  • Lower ticket volume
  • Higher article views
  • Better user feedback

6. Apply the Winning Variation

Update your help center based on real data, not assumptions.
