Types of Content to Test in WordPress

WordPress

WordPress lets you test different content elements. Here's what you can change and why it matters:

What to Test

You can test these parts of your WordPress site:

Element Test Ideas
Headlines Short vs. long, questions vs. statements
Main text Style, length, formatting
CTAs Button color, text, placement
Images Product vs. lifestyle, placement
Forms Number of fields, placement
Navigation Menu structure, item names

Why Test?

Testing content changes can:

  • Get more people to engage
  • Turn more visitors into customers
  • Make your site easier to use

For example:

Thrive Optimize lets you test landing pages. You could change a button color to see which gets more clicks.

Nelio A/B Testing helps you try different headlines. Make two versions and see which title gets more views.

"A/B testing helps WordPress site owners understand how users behave by comparing different designs, content, or features."

Just remember: Test ONE thing at a time. That way, you'll know exactly what caused any changes in your results.

Getting Ready for Content Tests

Before you start A/B testing on WordPress, you need to prep. Here's how:

Set Clear Goals

Don't just say "make the site better." Be specific:

"Boost email sign-ups by 20% this month."

Your goals should be measurable and tied to business objectives.

Pick the Right Metrics

Choose metrics that match your goals. Here are some common ones:

Metric What It Measures Use It When Testing
Conversion Rate Visitors who take action CTAs or forms
Bounce Rate One-page visitors Headlines or layouts
Time on Page Engagement duration Content length
Click-Through Rate Link clicks Navigation or internal links

What Content to Test

A/B testing in WordPress? Here's what you should focus on:

Headlines

Headlines are your first impression. Test these:

  • Short vs. long
  • Questions vs. statements
  • With numbers vs. without

For example:

"Boost Your SEO" vs. "5 Ways to Improve Search Rankings"

Main Text

Your content keeps visitors around. Try:

  • Short vs. long paragraphs
  • Bullet points vs. full sentences
  • Formal vs. casual tone

These drive action. Test:

  • Button text: "Buy Now" vs. "Get Started"
  • Button color: Blue vs. Green
  • Link placement: In-text vs. End of paragraph

Pictures and Videos

Visuals grab attention. Test:

  • Product photos: With models vs. standalone
  • Infographics vs. text-only content
  • Video length: 30 seconds vs. 2 minutes
Element Test Ideas Why It Matters
Headlines Length, style, tone First impression, click-through rates
Main Text Format, length, style Engagement, time on page
Buttons/Links Text, color, placement Conversion rates
Images/Videos Type, style, length Visual appeal, information retention

Understanding Test Results

A/B test data is crucial for improving your WordPress site. Here's how to make sense of it:

Reading Test Data

When you look at A/B test results, focus on these key metrics:

  • Conversion rate
  • Uplift
  • Confidence level
Metric Meaning Goal
Conversion Rate % of visitors who converted Higher
Uplift % difference vs. control Positive
Confidence Level Statistical significance 95%+

Don't jump to conclusions too quickly. Give your test about two weeks to gather enough data.

"A 95% confidence rating means there's a 1 in 20 chance you'd get different results if you ran the test again." - A/B Testing Expert

Using What You Learned

Got solid data? Time to act:

1. Implement winners

If a variation clearly wins, make it your new default.

2. Dig deeper

Even "losing" tests can teach you something. Look at how different groups responded.

3. Plan follow-up tests

Use what you've learned to form new ideas and keep improving.

4. Document everything

Keep a record of all your tests, results, and lessons.

A/B testing isn't a one-and-done deal. Each test builds on the last, helping you constantly improve your WordPress site.

Common Mistakes and How to Avoid Them

A/B testing can boost your WordPress site, but watch out for these pitfalls:

Changing Too Much at Once

Testing multiple elements? You're asking for trouble.

Problem Solution
Can't pinpoint what worked Test one thing at a time
Messy data Keep it simple
Wasted effort Plan your tests

Pro tip: Stick to one variable per page. It keeps things clear and actionable.

Not Enough Time

Short tests? Bad idea. Here's why:

  • Not enough data
  • Temporary factors mess things up
  • You miss the big picture

How long should you test? At least 1-2 weeks, but it depends on your traffic and conversions. Get enough data to draw solid conclusions.

Results That Actually Matter

Not all results are created equal. You need statistical significance.

Confidence Level What It Means
Under 95% Could be random
95% or more Probably legit

Remember: Look for a p-value below 0.05.

More Advanced Testing Methods

Want to level up your WordPress A/B testing? Let's dive into some advanced techniques.

Testing Multiple Changes

Sometimes, you need to test several changes at once. This is called multivariate testing.

Method Use Case Example
A/B Test One change Button color
Multivariate Multiple changes Header + CTA + Image

Watch out: Multivariate tests need LOTS of traffic. Make sure you've got enough visitors before jumping in.

Testing for Different Groups

Not all visitors are created equal. By segmenting your audience, you can tailor content to specific groups.

Segment by:

  • Location
  • Device type
  • New vs. returning visitors
  • Traffic source

Pro tip: Use WordPress plugins that support user segmentation. It'll make your life easier.

Changing Content for Each Visitor

Want to get personal? Show different content to each visitor based on their behavior or traits. This method, often called dynamic content, can seriously boost engagement.

Here's the gist:

  1. Collect visitor behavior data
  2. Use AI or rules to decide what to show
  3. Display personalized content in real-time

Real-world example: The Obama 2012 Campaign used this approach for online fundraising. They ran over 500 experiments in 20 months, helping them raise $690 million online.

Wrap-Up

A/B testing in WordPress can boost your site's performance. Here's what you need to know:

  • Test one thing at a time
  • Set clear goals
  • Use WordPress A/B testing plugins
  • Look at your data
  • Keep testing

Why keep testing? Your site can always get better. Users change. New features pop up.

"A/B testing in WordPress helps you make smart choices. It's all about using data to improve your site." - Acclaim Team

Even small tweaks can make a big difference. For example, adding customer reviews to a page might get more people to buy.

Test This It Might

Remember: A/B testing isn't a one-and-done deal. It's an ongoing process to keep your WordPress site at its best.
