How to: A/B Testing

Your campaign’s success can be influenced by any element – a trigger, an image, text, or even an offer. Your goal should be to discover the most profitable pairing: a clickable landing page and an offer that drives conversions. That’s where A/B testing comes along.

A/B testing, or split testing, compares two or more versions of a webpage or other user experience to determine which performs better. 

By utilizing Keitaro, you can incorporate an unlimited number of landing pages, set their display frequency (percentage), and monitor the effectiveness of each. This allows you to gauge the number of transitions to the offer from each landing page and pinpoint the most engaging one.

Moreover, Keitaro allows the selection of the placement ID from which the transition to the landing page is made, an attribute that can prove particularly beneficial when tailoring your campaign to various traffic sources.

Tools like Keitaro can significantly streamline the A/B testing process and assist in uncovering the most profitable pairings for your digital marketing initiatives. You can read more about how to set up A/B testing in Keitaro here.

Guidelines for A/B Testing

Just starting with A/B testing? While no one-size-fits-all advice exists, the following widely accepted tips can enhance your testing procedures and potentially lead to superior outcomes.

Ensure a Sufficient Testing Duration

Making sure your A/B testing runs for an adequate duration is paramount. It’s recommended that you run your test for at least 4-5 days. 

This is because shorter durations might not provide a representative sample of your user base and their behaviors. You have to be able to collect data across different times and days of the week, accounting for possible variations in user activity. This will ensure the data you collect is comprehensive, giving you a more accurate picture of user response to your tested elements. 

Furthermore, this duration helps ensure the statistical validity of your results, as larger sample sizes reduce the margin of error and increase the reliability of the data. Remember, haste in drawing conclusions from shorter tests might lead to decisions based on aberrations rather than genuine user behavior trends.

Set Aside a Budget for Testing

A portion of your overall campaign budget should be allocated specifically for testing. It’s generally suggested that you allocate around 25-30% of your total budget for this purpose. 

This testing budget is essential because it allows you to conduct multiple tests without worrying about draining the resources required for the full-scale campaign. It’s important to understand that A/B testing is an iterative process – you might need to run multiple tests, tweaking different elements each time, before arriving at the optimal solution.

Having a dedicated budget for testing can prevent oversights and unplanned spending, which can be especially important in more extensive campaigns where expenses can quickly escalate. In addition, this practice ensures that the testing phase, despite being resource-intensive, is a planned, organized part of your overall campaign strategy.

Measure Success 

Establishing a metric, or set of metrics, for defining success beforehand gives you a benchmark to compare your test results to. This definition of success should be influenced by factors such as your budget size, projected conversion rates, and the specific objectives of your campaign.

Go from General to Specific 

It’s the approach where you commence by testing broader elements and gradually refining to more specific details. 

Initially, consider conducting broad-scope testing. This could include comparing vastly different designs, content structures, user paths, or Geos.

Once you’ve identified successful elements on a broad level, you start narrowing your focus to refine specific details. For example, if your broad test revealed that users prefer design A over design B, you would then conduct more particular tests on design A. This might involve changing the color of a button, the wording of a call-to-action, or the placement of an image. These smaller, more granular tests help you optimize specific aspects of the user experience to improve your results further.

The main advantage of this approach is that it avoids getting lost in details before understanding the big picture. It helps prevent the scenario where you’re optimizing tiny details that don’t matter because you’re missing a larger issue that’s impacting your results.

Identify the Testing Variable

Choose an element or feature of your webpage, email, or advertisement that you plan to alter for the test while keeping all other elements constant. This approach isolates the effects of that single change and accurately measures its impact on user behavior or conversion rates.

Changing multiple elements simultaneously could muddle the results, making it unclear which change resulted in the observed differences.

Adopt Continuous Testing

Adopting continuous testing as part of your routine is essential to ensure ongoing optimization and improvement of your campaigns. While A/B testing is a valuable technique, it’s vital to understand that there is always room for improvement, even when you identify what appears to be the best-performing option. Here are some ways to enhance your continuous testing approach:

  • Continuously test different variations of creatives, such as images, videos, ad copy, and headlines. Experiment with varying messaging styles, calls to action, and visual elements to identify the most compelling combination that resonates with your target audience.
  • Test how your ads perform on laptops, smartphones, and tablets. Optimize your creatives and landing pages to ensure a seamless and engaging experience across various screen sizes and device types.
  • Test new keywords and variations to expand your reach and capture more relevant traffic. Monitor CR and CTR to identify high-performing keywords and eliminate underperforming ones.
  • Experiment with different timings to understand when your conversion rates are highest, and lead costs are lowest. Test running your ads at various times of the day, on different days of the week, and even during specific seasons or events. This data can help you allocate your budget more effectively and maximize your ROI.
  • Regularly analyze the results of your tests and use data-driven insights to inform your decision-making process. Monitor key metrics such as click-through rates, conversion rates, cost per acquisition, and return on ad spend. Identify trends, patterns, and correlations in the data to make informed adjustments and optimizations.

Prepare Ahead

Staying prepared and having backup creatives ready is essential to agile campaign management. 

  • Develop a pool of alternative creatives that align with your campaign objectives and messaging. These could include different variations of images, videos, ad copy, headlines, and calls to action. By having a range of options available, you can quickly swap out underperforming creatives or adapt to changes in the competitive landscape.
  • Look for warning signs that indicate your campaign is losing steam or becoming less effective. These signs can include a decrease in click-through rates, a rise in cost per acquisition, a drop in engagement, or a decline in overall campaign performance. By proactively monitoring these indicators, you can be prepared to take action when necessary.
  • Anticipate potential scenarios where your campaign may need adjustments. For example, if a competitor adopts a similar pairing or creative strategy, have alternative creatives ready that can differentiate your campaign. Likewise, if your current creative approach starts losing steam, be prepared to implement backup creatives that can reinvigorate your campaign.
  • Embrace an agile mindset in your marketing strategy. Continuously monitor the market, competitive landscape, and consumer trends. This allows you to adapt quickly and proactively to changes, ensuring your campaigns remain practical and relevant.

A/B testing is an invaluable tool for digital marketers. It’s a methodical process that requires a balance of creative experimentation, robust data analysis, and a steady budget dedicated to testing. Tools like Keitaro simplify this process, making it an integral part of your ongoing campaign strategy.

Always remember to start broad and refine, identify your testing variable, and measure success with well-defined metrics. Continuously test and analyze to stay ahead of the curve and remain agile in your marketing strategy.

Successful A/B testing is a blend of disciplined experimentation, continuous learning, and strategic adaptation. It’s a powerful technique that can significantly enhance your campaign’s effectiveness and overall business performance.
