A/B testing (also known as split testing or bucket testing) is a method of comparing two versions of a webpage or app against each other to determine which one performs better.
A/B testing is the practice of showing 2 variants of the same web page to different segments of visitors at the same time and comparing which variant drives more conversions. Typically, the one that gives higher conversions is the winning variant, applying which can help you optimize your site for better results.
A/B testing is a way to compare two versions of a single variable, typically by testing a subject’s response to variant A against variant B, and determining which of the two variants is more effective.As the name implies, two versions (A and B) are compared, which are identical except for one variation that might affect a user’s behavior. Version A might be the currently used version (control), while version B is modified in some respect (treatment).
A structured A/B testing program can make marketing efforts more profitable by pinpointing the most crucial problem areas that need optimization. A/B testing is now moving away from being a standalone activity which is conducted once in a blue moon to a more structured and continuous activity which should always be done through a well-defined CRO process. Broadly, it includes the following steps:Collect Data:
Your analytics will often provide insight into where you can begin optimizing. It helps to begin with high traffic areas of your site or app, as that will allow you to gather data faster. Look for pages with low conversion rates or high drop-off rates that can be improved.Identify Goals:
Your conversion goals are the metrics that you are using to determine whether or not the variation is more successful than the original version. Goals can be anything from clicking a button or link to product purchases and e-mail signups.Generate Hypothesis:
Once you’ve identified a goal you can begin generating A/B testing ideas and hypotheses for why you think they will be better than the current version. Once you have a list of ideas, prioritize them in terms of expected impact and difficulty of implementation.Create Variations:
Using your A/B testing software (like Optimizely), make the desired changes to an element of your website or mobile app experience. This might be changing the color of a button, swapping the order of elements on the page, hiding navigation elements, or something entirely custom. Many leading A/B testing tools have a visual editor that will make these changes easy. Make sure to QA your experiment to make sure it works as expected.Run Experiment:
Kick off your experiment and wait for visitors to participate! At this point, visitors to your site or app will be randomly assigned to either the control or variation of your experience. Their interaction with each experience is measured, counted, and compared to determine how each performs.Analyze Results:
Once your experiment is complete, it’s time to analyze the results. Your A/B testing software will present the data from the experiment and show you the difference between how the two versions of your page performed, and whether there is a statistically significant difference.
A/B testing has a multitude of benefits to a marketing team, depending on what it is you decide to test. Above all, though, these tests are valuable to a business because they’re low in cost but high in reward.Increased Website Traffic:
Testing different blog post or web page titles can change the number of people who click on that hyperlinked title to get to your website. This can increase website traffic as a result.Higher Conversion Rate:
Testing different locations, colors, or even anchor text on your CTAs can change the number of people who click these CTAs to get to a landing page. This can increase the number of people who fill out forms on your website, submit their contact info to you, and “convert” into a lead.Lower Bounce Rate:
If your website visitors leave (or “bounce”) quickly after visiting your website, testing different blog post introductions, fonts, or feature images can reduce this bounce rate and retain more visitors.Lower Cart Abandonment:
Ecommerce businesses see 40% – 75% of customers leave their website with items in their shopping cart, according to MightyCall. This is known as “shopping cart abandonment.” Testing different product photos, check-out page designs, and even where shipping costs are displayed can lower this abandonment rate.

Google Analytics ‘Experiments’ makes it a complete A/B testing platform which utilizes Googles multi-armed bandit approach. The tool allows you to split-test up to 10 full versions of a single page, each delivered to users from a separate URL. You can compare different web pages’ performance using a random sample of users, with the ability to define what percentage of your users are included in the experiment. Using the Content Experiments API you can run tests sever side and implement different recommendations or search algorithms. There’s also no redirects, as the API allows testing changes to content without redirects, and is simple to implement.Convert Experiment:
