The Best A/B Testing Tools to Use With Realize
Sohel
A/B testing has become indispensable for performance marketers looking to optimize their campaigns and maximize ROI. While Realize offers robust built-in testing capabilities, integrating complementary A/B testing tools can take your optimization efforts to the next level. This comprehensive guide explores the best A/B testing tools that work seamlessly with Realize to help you make data-driven decisions and boost conversions.
Before diving into third-party tools, it’s important to understand what Realize offers out of the box.
Realize enables multivariate testing by allowing you to upload multiple headline and image combinations. The platform distributes traffic evenly across variations in A/B Testing mode, letting the algorithm identify winners after sufficient data collection. Once testing concludes, campaigns automatically switch to Optimized delivery, prioritizing top-performing creative combinations.
Realize leverages Taboola’s predictive AI capabilities through features like:
While Realize excels at ad creative testing, it doesn’t provide deep on-site experimentation capabilities. This is where third-party A/B testing platforms become essential for optimizing the post-click experience.
These platforms offer seamless integration with Realize, creating a unified optimization workflow.

When running A/B tests that involve URL changes, ensure compliance with Google’s guidelines:
Define Your Hypothesis: Start with a specific, testable hypothesis about what will improve performance and why.
Test One Variable at a Time: Isolate variables to understand exactly what drives performance changes (unless running multivariate tests).
Use Adequate Sample Sizes: Ensure statistical significance by running tests long enough to gather sufficient data – typically several weeks.
Document Everything: Record what you tested, why, and the results to inform future optimization efforts.
Monitor metrics that align with your business goals:
Watch for negative impacts like increased page load time that could hurt user experience.

Run tests for a minimum of one to two full business cycles (typically 2-4 weeks) to account for weekly patterns. Continue until you reach statistical significance, usually requiring hundreds to thousands of conversions per variation.
Yes, but ensure tests don’t overlap or interfere with each other. Test different elements (like ad creative in Realize and landing page headline in your testing tool) rather than competing variations of the same element.
A/B testing compares two versions of a single element. Multivariate testing simultaneously tests multiple elements to understand both individual impact and interactions between changes.
Follow Google’s guidelines: use 302 redirects for URL-based tests, add canonical tags to variations, avoid cloaking, and run tests only as long as necessary to gather meaningful data.
Sample size depends on your baseline conversion rate, expected improvement, and desired confidence level. Use online calculators to determine requirements, but generally aim for at least 100-200 conversions per variation.
Both have value. Incremental tests help optimize existing approaches, while radical tests can reveal breakthrough opportunities. Balance quick wins with bold experiments in your testing roadmap.
Realize provides powerful native A/B testing capabilities for ad creatives and campaign optimization. However, maximizing performance requires a comprehensive approach that extends beyond the ad platform to landing pages, user journeys, and conversion funnels.
By strategically integrating tools like AnyTrack for accurate tracking, Leadpages for landing page testing, VWO for comprehensive optimization, and automation platforms like TheOptimizer, you create a complete testing ecosystem that drives continuous improvement.
The key is selecting tools that align with your team size, technical capabilities, budget, and specific optimization goals. Start with Realize’s native features, add integrated partners for seamless workflows, and expand to specialized platforms as your testing maturity grows.
Remember: successful A/B testing isn’t about having the most tools—it’s about using the right tools effectively to make data-driven decisions that improve user experiences and drive measurable business results.
