Learn more about A/B testing for your marketing campaigns

 In today’s fast-paced digital landscape, fine-tuning your ad campaigns can make all the difference between success and missed opportunities. One of the most effective methods to optimise your digital marketing efforts is through A/B testing. This powerful tool allows you to test different variables within your ads to see which performs best, providing valuable insights that drive your campaign objectives.

What is A/B Testing?

A/B testing, also known as split testing, is a method where you compare two versions of an ad to see which one performs better. Each group sees ads that are identical except for one variable you want to test. This could be anything from delivery optimisation, placement, creative elements, or even the audience itself.

How A/B Testing Works

  • Test Groups: Split your audience into two groups. Test group 1 sees version A of your ad, while test group 2 sees version B.
  • Measure Performance: Track how each ad or ad set performs against your campaign objectives.
  • Identify the Winner: The ad or ad set that achieves the best results is considered the winner.

A/B tests can be applied to various ad objectives such as Awareness, Engagement, Traffic, App Promotion, Leads, or Sales. They are budget-friendly compared to lift tests and typically run for 3–14 days, making them ideal for quick and tactical optimisations.

A/B Test Setup Checklist

Before diving into an A/B test, ensure you’re fully prepared. Here’s a handy checklist to guide you through the process:

  1. Duration: Run the test for 1–2 conversion cycles or at least two weeks.
  2. Budget: Allocate equal budgets to both campaigns. The budget should be high enough to exit the learning phase. The minimum weekly ad set budget must be 50 times the one-day click cost per action (CPA), with a conservative minimum being 100 times the average CPA.
  3. Creative: Include a prominent call to action and consistent branding in each ad.
  4. Audience: Minimise audience overlap with other campaigns or ad accounts to reduce the possibility of inflating the baseline.
  5. Dark Period: Consider implementing a pre or post-study media dark period to minimise the likelihood of contamination.

Analysing A/B Test Results

After running your test, there are two potential outcomes:

  • Declared Winner: If your test declares a winner, proceed with the winning strategy and explore other variables to test.
  • No Winner: If there’s no clear winner, adjust your campaigns and rerun the test. Optimise the creative and refer to the setup checklist to enhance your campaign and measurement practices.

Key Points to Remember

  • Evaluation Timing: Wait until the end of the study to evaluate your results.
  • Reliability Threshold: Any result with a confidence level of 90% or higher is considered reliable.
  • Conversion Requirement: The combined A/B test groups need at least 100 conversions before the tool can show reliable results.

A/B testing is a strategic tool for marketers looking to make data-driven decisions. By carefully setting up and analysing your tests, you can continuously optimise your ad campaigns, ensuring you achieve your marketing objectives effectively. Implement A/B testing in your digital strategy today and unlock the potential for greater campaign success.
