In marketing optimization, A/B testing is crucial. Marketing professionals can now test and compare their campaign variations to identify the most successful campaign strategy with the help of this technique.
In this article, the art of A/B testing is examined, and it is demonstrated how marketers can get the most out of their work through data-driven experiments, resulting in improved engagement, increased conversion rates, and overall superior performance.
What is A/B Testing?
A/B testing compares two or more marketing element versions to determine which works best. For instance, if you carry out SEO services in Lichfield, you can conduct an A/B test on a landing page. You can make minor changes to a collection of pages and track their optimisation impact. Another example is testing a variety of fonts on a button to determine if you can boost button clicks.
Generally, a call to action, headline, layout, or other elements could represent any of the two versions (A and B) the marketers create and test.
Once the versions are shown to the target audience, measurements and analysis are done on their reactions and interactions.
In simple terms, two versions: A and B are laid side by side and presented to users to see which they prefer.
How to Conduct A/B Testing
Before you begin an A/B test, there are a lot of boxes that need to be checked to ensure the real process goes on smoothly and produces a tangible result. So, let’s start with ‘before the process’ shall we?
- Take it one variable at a time
You should test one variable at a time while optimizing your emails and web pages.
This would help in assessing the performance of the single independent variable whenever it is measured.
Should this not be the case, it would not be possible to know which variable caused performance variations.
2. Establish your goal
You will have to measure multiple metrics at once, so it would be wise to choose a primary metric to focus on before running the test.
Do this before you set up the second version to be tested, as that will be your dependent variable.
Any alternatives that occur in the dependent variable will depend on your ability to control the independent variable.
Considering the result you would like this dependent variable to have after the A/B test, this would enable you to make a proper hypothesis and evaluating your results in that light would be feasible.
If this is not done beforehand, it might affect how your users respond to the changes you’re proposing and the overall configuration of the test.
3. Set up a ‘Control’ and ‘Contender’ Group
Once you have gotten your independent and dependent variable, as well as the objective for your experiment, it is time to divide the two variant into a control and contender group based on the information you’ve gathered.
The control group is the unfiltered, neutral group while the contender group is the group that has received modifications.
For example, if you a conducting the A/B testing on a landing page, the ‘control group’ would be the initial landing page design that your company/brand has been using while the ‘contender group’ would be the new landing page design with the new features and modifications that have been incorporated into it.
4. Divide Your Sample Groups Evenly and Without a Conscious Choice
This is necessary for situations where you have better sway over your audience, e.g. email. You will need your audience to be evenly and randomly distributed numerically in order to have an unbiased and undeniable result.
5. Decide the Level of Significance You Want Your Results to have
Most marketers get confused when it comes to the statistical significance of the A/B testing process.
But in a real sense, it is all about how confident they want to be about their results.
The greater the percentage of your confidence level, the more certain you’d be of your results. Most of the time, especially if the experiment took a long time, you’ll want a confidence level that is nothing short of 95%.
The Main Process Begins
- Make Use of an A/B Test Tool
To effectively conduct an A/B test, you’ll need to use an A/B test tool and Google Analytics is one of such tools. It allows you the liberty to test numerous versions of a web page and helps you with analysing the performance metrics of your test.
2. Conduct Your A and B Version Tests at the Same Time
Because timing is important in marketing campaigns, it is imperative that you conduct your A/B test on the two versions of your experiment at the same time.
If this is done oppositely, you are at risk of not being sure of your results. For instance, you might not know if your audience’s positive/negative response is towards version A or B when they’re timed at two-month interval.
3. Allocate Ample Time for Your A/B Test to Produce Results
Now that you are running the test on your A and B versions simultaneously, feel free to allocate enough time so that you would have tangible results to work with.
Also, you’d want to allocate time based on how large your sample size (audience) is.
This way you should be able to get statistically significant findings for your experiment.
4. Request the Opinion of Real Users
Using the example of the web page A/B testing, you can add a departing survey or poll to your web page so that whenever visitors want to leave your page, you can find out why they did or did not fill out a form, click on a CTA, or make payment for an item they added to cart (in the case of commercial webpages).
This is an effective way to get users undiluted opinion on your experiment and it will serve as a useful insight to improve how your audience responds to your product or service.
Conclusion
At the end of an A/B testing, a marketer should be able to make better and informed decisions concerning marketing campaign thereby making improvements and enhancing their user experience.
