Marketing thrives on making quick, data-driven decisions. Yet, for many marketers, web A/B testing has been a source of frustration with flickering pages, broken elements, and the endless headaches of visual editors. What if you could achieve a seamless experience of engineering-level precision without actually needing engineering?

Now, you can do it with the Eppo-Contentful integration. Teams can now craft and manage content directly within their CMS, rather than relying on clumsy tools to build A/B test changes. Want to run an experiment? Simply flip a switch to turn your new changes into a test variation with no engineering roadblocks and zero stress.

Here’s how it works. The Eppo-Contentful integration requires a small one-time engineering setup. After that, teams use the entry ID of any piece of content in Contentful to define experimental variations, creating a powerful, scalable workflow. By combining two best-in-class tools, this integration unleashes no-code experimentation, empowering marketers to test and iterate without limits.

The Challenges Marketers Face

Experimentation is every great marketer's superpower. Testing new ideas and understanding what works can amplify impact, but common hurdles make it harder to capitalize on this potential:

  • Engineering Dependencies: Traditional A/B testing demands engineering support to set up feature flags, modify codebases, and manage backend workflows. Waiting on these resources slows progress.
  • Tool Overload: Managing experiments across multiple platforms creates unnecessary complexity and increases the risk of errors.
  • Performance Hits: Client-side scripts often cause flickering or slowdowns, disrupting user experience and compromising data accuracy.

These roadblocks can leave marketers feeling stuck, unable to iterate quickly or confidently prove results. That's where the Eppo-Contentful integration comes in.

Why Eppo + Contentful Is a Game-Changer

This integration transforms the way you run experiments. Bringing Eppo's powerful experimentation capabilities directly within Contentful's headless CMS eliminates the need for constant engineering support and keeps everything streamlined in one platform. With everything served from the server, you can test hero images, copy, or even entire layouts seamlessly, all without sacrificing performance or user experience.

What Sets It Apart?

Unlike other solutions, the Eppo-Contentful integration avoids the challenges of performance-hurting client-side scripts. Instead, it relies on a headless CMS with feature flagging to keep your site fast and reliable.

Its benefits include:

  • Zero Reliance on Engineering Teams: Set up and run experiments entirely from Contentful's interface without waiting on backend work or sprints.
  • Top-Notch Performance: Forget page flickers. Your experiments are embedded directly into your site without slowing it down.
  • Effortless Setup: Installing Eppo's Contentful app is as easy as a few clicks, and its intuitive design makes experimentation accessible for marketers of all tech skill levels.

Here's How It Works

Getting started is easy and designed with marketers in mind:

  1. Install the app from the Contentful Marketplace and input your Eppo API key.
  2. Configure content types you want to test: blog posts, hero images, or banners.
  3. Create content variations, such as alternate CTAs, colors, or headlines.
  4. Publish and automate via Contentful, where Eppo automatically generates the necessary feature flags in its system.
  5. Enable and Go Live with a single click in Eppo, bringing your experiments to life.
  6. Track results using Eppo's analytics to find the winning variation backed by complex data.

This happens in a single workflow, without switching between tools or tedious handoffs.

Real-World Use Cases

Picture these scenarios where the Eppo-Contentful integration solves real marketing challenges:

1. Optimize Landing Page Conversions

You're launching a major product campaign and want to test different hero images. With the integration, you can create variations directly in Contentful, publish experiments, and identify the winning design while keeping load times blazing fast. There is no need to involve engineering at any point.

2. Maximize Blog Engagement

Are you struggling with bounce rates? Experiment with blog post headlines or introductory text to see what keeps readers engaged longer. Using this integration, changes can be easily made and tracked across thousands of posts, saving countless hours of manual updates.

3. Test Different Offers for Targeted Audiences

Want to test a new discount but don’t want users randomly seeing different prices as they go from mobile to desktop? Eppo supports regionally-randomized experiments, called Clustered Experiments. You can implement them via Contentful and analyze them natively. With this method, every user in the test regions will see the same price, but when it comes time to analyze the results, you can compare results user-to-user, accounting for regional variations. Use the integration to tailor messages like banners or CTAs for specific locations. Testing multiple designs or texts doesn't require new code, just a few configurations in Contentful. 

4. Refine Call-to-Actions

Eppo makes it easy to experiment with CTAs like "Get Started" vs. "Learn More" or even entire boxes with varying designs and copy. Consistent across pages but customizable where needed, you can improve clicks and conversions with actionable insights.

Smarter Marketing Starts Here

Great marketing isn't just about big ideas; it's about testing, learning, and iterating. The Eppo-Contentful integration allows you to experiment boldly without compromising speed or site performance, no more waiting or bottlenecks.
