A/B Testing

A/B Testing

A/B testing is a methodology that reveals the user experience. This test measures users’ interactions over two variables. It measures two different variables with systematic and theoretical analysis, leaving other factors the same. These statistical values are useful in measuring ad performance. A performance agency often tests different variables. This way, it tries to evaluate the most accurate user experience or budget cost. A Google ads agency has important metrics for the A/B test. This means that the A/B tests contain multiple metrics. The measurements that A/B test reports by analyzing potential customers’ experiences are as follows:

  • Correct ad text
  • Appropriate budget
  • Right ad design

Putting variables to the test for a successful marketing campaign always helps to find the more effective one. A/B test allows you to see which of the two different content ads, e-mail, or webpages perform better. The only difference between those tested is one element. This element may be the title, CTA image, or content. A/B testing requires control results. That’s why the A/B test has an expansion. A contains the control results of the current situation. B is the variation where you will compare A with the results.

Why Should I Make A/B Testing?

You may have Front-End and Back-End projects and may decide to make innovations and improvements on your website. You should test whether these improvements make a meaningful difference according to some criteria. A/B test results will help you make the right improvement for your web page. A/B testing variations allow you to test your website towards various elements. There are also testing tools that can make your testing experience easier. With these tools, you can test multiple variables at the same time. There are a few important points to be aware of when applying this test. Missing or misunderstanding statistical tests can lead to fatal errors. Such situations will cause errors in the study and results with low reliability. A/B testing has three main uses. These are as follows:

  • Optimizing customer journey steps. In other words, to increase conversion rates on online commerce sites.
  • The second is innovation or improvement in the front-end section. These might be an ad space change, menu change, color change, button color change.
  • Last of all is a revenue-driven performance of a machine learning project in life.

Apart from these areas of use, there are also many various usage areas. However, tests generally take place around these situations for a website. Let’s explain how you can measure these innovations and improvements. We will also explain how to use these statistical tests.

How Should You Do the Tests?

When applying the test, there are some things you need to determine correctly.

Collecting the Right Data

  • Determine the area where you will apply the test.
  • Identify the correct volume and the causative situation.
  • Determine the target audience to test.

As an example, you will test for a situation on different sites of a brand. For this, you have to calculate all these variables differently. This should be different from the variables you would test on a single web page of the same brand. Or, it may be different products of the same brand on a commercial web page. Here, you need to design different tests for each product description on this web page. Let’s examine an example now.

You will change the color of a button on your web page. For this, you need to decide which color the button should be. In this case, you must create test and control groups. In this case, three main situations that we mentioned earlier will arise. These three main issues arise from three questions.

  • How to choose test and control groups?
  • How to collect data for these groups, and what sources to use?
  • What will be the volumes of data you collect?

You have to give theoretical answers to these questions. Because the tests you applied may have theoretical assumptions.

Choose the Right Measurement Tool

The problem here is the conversion rate problem. Because at this stage, you need to measure a few data by number. These data are as follows:

  • How many:
    • people have seen your product?
    • people bought your product?
    • clicks did your product get?

All of these questions are about the number of people on your web pages. The equivalent of these measurements in statistics is the p ratio test. You may consider examining the differences between direct conversion rate values or cumulative total for such a situation. But, this will be a wrong decision. The problem could have been related to the revenues of a live ML project. In this case, the test method would not be a p ratio test. In this case, the test type would be independent or dependent t-test. Let’s move on to step three.

You need to establish correct statistical hypotheses. Then you have to test these hypotheses correctly. When establishing these hypotheses, there are two terms whose meaning you need to know. These terms are H0 and H1.

  • H0 means there is no difference between the conversion rates of the old and new system, statistically.
  • H1 means there is a difference between the conversion rates of the old and new system, statistically.

Let’s assume you have the correct test method and the correct hypothesis test set up. Now you may move on to the next step.

determine the measurement time

Determine the Measurement Time

This question is the key point of these studies. There is no single valid approach to this topic. When deciding this, you should take into account all three factors. These factors are business knowledge, the law of large numbers, and the sampling theory. Here, you should act with the assumption that the results of the experiments occurring in each period are an observation. So, here two questions arise. Are you going to make the rate test for the observations you make today? Or, will you do a ratio test based on the observations that occur within a week?

Provide the Business Units with the Interpretation of the Hypotheses

Suppose you have followed the steps outlined in the steps we mentioned above. At this point, we have the data we have obtained for 30 days of two groups. As a result of these tests, button renewal gave successful results with the p ratio test we operated. So, let’s move on to the evaluation of this step now. Here, you have to pay attention to how to interpret the H0 hypothesis. Academic staff will review the results of this hypothesis test. If you don’t put the letters in a word correctly, no meaningful words will emerge from those letters. The same is true while evaluating statistical data. You must make all the processes that are intertwined in all tests and interpretations correct and complete. Otherwise, you’ll get results that don’t make sense.

Let’s assume your H0 hypothesis test has resulted. If the result is H0 rejected, it means changing the button color makes a difference. At this stage, you should give the necessary notifications to your business units regarding these test results. Let’s assume now the H0 hypothesis came to an irrefutable result. In that case, you could tell your business units that there is no point in making changes. Besides, you should also create hypotheses for testing machine learning project outcomes. R application will take place for these.

The Importance of A/B Testing

For A/B testing, you must first decide what value you want to test. The algorithm of the test basically works by comparing the two values. Thus, it helps you find which of these values is more successful. It starts to show users the same settings and variables to find out which one is more successful. As a result of this process, it produces results that will help you. The data it collects with the featured variation helps for your website arrangements and the next advertising work.

Let’s assume you have a variation on your website. One of them might be ahead in the A/B test result. That means you have found the correct values to base on in your future revisions. A/B test results also help you in another area. You may use these results to use measured values in the optimization of your advertising images. This way, you will have the chance to progress on real results instead of predictions. So, instead of estimated values, you will switch to known values.

Each brand and ad’s target audience, interaction, and budget are different. Therefore, it is not possible to have only one truth for everyone. An improvement could work for the x brand. However, the same improvement might not work for the w brand. A/B test helps you make the right decision on variables. Since it makes these decisions with the test method, it almost guarantees these results.

With A/B testing, you may also perform product development tests that appeal to the user experience. It is also possible to do graphical tests. A/B test results start to come through two different products that you show your target audience. Thus, step by step, you will approach the correct product development method for your brand. A/B test shows both which is more effective and which is more ineffective. So, with this test, you will find both your positive and negative values.
