How to A/B Test in Google Ads Using Campaign Experiments

A successful way for you to improve your Google AdWords marketing is by means of A/B testing. By means of Campaign Experiments you may try out different versions of ad to find the most effective ones.

In this post, we will cover how to run A/B testing with Google AdWords Campaign Experiments. This will be an aid for you to improve your campaigns and to deliver better outcomes, particularly for the digital marketing in Houston market. There is very high competition, and the right strategy is essential.

Let’s get down to the business of maximizing your advertising impact!

Understanding A/B Testing

It is called A/B testing or split testing and is to create multiple copies of your ads and show them to different audiences. Through contrasting the level of performance of these versions, you can trace the factors that are the most effective in what you are looking for, for instance, clicks, conversions, or engagement.

Introducing Google Ads Campaign Experiments

Google Ads Campaign Experiments is a feature that helps advertisers to experiment with changes to their campaigns in a controlled environment, where A/B testing is possible without affecting the existing ad performance, thus enabling accurate data to be collected without any risks to the existing ad performance.

Steps to Conduct A/B Testing Using Campaign Experiments

Create a Draft

First of all, draft the campaign you are going to experiment with. It enables you to modify your ads, key phrases, bidding strategies, or the settings of your campaigns that are running without affecting the other campaigns.

Make Changes

It is now time for you to make the needed modifications to either the ads or the campaign settings of your ad campaign. For instance, you could produce different versions of your ad and analyze the results, try various bids and examine the outcomes, or modify your targeting options for better outcomes.

Set Experiment Parameters

Through Google Ads, you can define the parameters of the experiment such as the percentage of your budget that is allocated to the experiment, time frame and metrics for the performance you want to track.

Launch the Experiment

After the experiment aims and parameters have been set up, you can start the experiment and begin collecting data. Google Ads will systematically allocate the budget for the control (original) and experimental (variation) campaigns. This means that the campaigns will be compared in a fair manner.

Monitor Performance

Keep the control and experimental groups under close supervision during the entire experimentation period. Watch for those metric indicators like click through rate (CTR), conversion rate, cost per acquisition (CPA), or return on ad spend (ROAS).

Analyze Results

Analyze the data to determine which variation was more effective when your experiment has been completed. To identify the winning variations and insights that can inform future optimization, look for statistically significant differences in performance metrics.

Benefits of Using Campaign Experiments for A/B Testing

Running a true A/B test with campaign experiments has significant benefits for optimizing your digital marketing efforts. Read below:

  • Controlled Testing Environment: Tests campaigns in a controlled setting where they cannot affect operating campaigns, minimizing harmful impact.
  • Accurate Data Collection: Conducts separate experiments running in parallel with main campaigns, checking for data correctness.
  • Data-Driven Decision Making: For example, it will be able to determine what works and what doesn’t.
  • Cost-Efficient Optimization: It pinpoints areas for improvement that will enhance the efficiency and effectiveness of advertising, hence delivering the best ROI. Dropbox

Best Practices for A/B Testing with Campaign Experiments

  • Test One Variable at a Time: To identify the effect of individual modifications, try testing for one variable in each instance, including copy, keywords and bidding strategies.
  • Define Clear Objectives: Before an experiment is started, it is important to establish clear goals and KPIs for assessment of effectiveness. It will enable you to focus on the key metrics that drive your business goals to the maximum extent.
  • Be Patient and Methodical: An/B testing is a procedure that is not only slow but also requires careful study of the collected data. Provide enough time for your experiments to show up results and to collect useful data before to come up with the conclusions or alterations.
  • Iterate and Optimize: Use the gains from your A/B tests to keep on working on your campaigns and gradually improve them. Try out the new ideas and strategies all the time and then see if you can keep your advertising performance better each time.


Testing of A/B variants has become a very important tool for optimizing Google Ads campaigns and making advertising more efficient. It provides advertisers the opportunity to conduct controlled experiments for testing different versions of advertisements as well as for the campaign settings, thus enabling decision-making based on the data and the continuous optimization. By that, there will be a smooth process that will eventually unlock the full power of advertising.
