Did you know you can increase sales without increasing traffic?

Now, I know that you’re thinking. It seems a little dubious.

But it’s true. 

A/B testing is a fantastic way of improving your website’s conversion rate with a strategy based on facts and data.

In its simplest form, an A/B test runs two versions of the same page to a random audience selection. 

The aim of this is to find out how an audience reacts to these new changes and if it helps you reach your business goals.

You can use A/B testing on everything, from websites to landing pages, advertising to social media messages. It’s an important marketing tool which helps you gain the best bang for your buck.

Let’s explore what A/B testing is and how it can improve your conversion rate.

What is Conversion Rate?

A/B testing usually revolves around conversion rate.

A conversion rate is a percentage of people who land on a page and complete a goal.

So, for example, a e-commerce store gets 100,000 visitors every month. The website’s goal is to sell products. Of those 100,000 people who land on the website, 4,000 people buy something.

So the conversion rate equation would look like this:

4,000/100,000*100= 4%

Conversion rate isn’t just about sales. A conversion rate could look at:

Your conversion goals can be anything you need to hit your business goals.

What is A/B Testing?

A/B testing looks into how to improve the conversion rate of a specific goal based on improving your marketing material.

So how do you do that?

A/B testing runs two different versions of a piece of marketing collateral to audiences. This could include a webpage, an email, an ad or more.

These tests usually include the original (control) and one changed version (variation). These are then shown to your audience without them knowing it’s a test. Traffic to these variations is divided between a predetermined audience split, such as 50/50, 75/25, etc.

A/B testing software will then track the conversion rates of these pages. Whichever page gains the highest conversion rates or biggest sales will be crowned champion. You can then decide to implement those changes permanently or try further tests.

It’s important that you only run one test at a time, especially if you are just starting out. Running multiple tests can muddy results, and if you are new to A/B testing, it can be very difficult to see the overall effect of each changed element. Stick to just one test at a time for the best results.


The A/B Testing Process

There is a method to A/B Testing that you should follow for every cycle of testing you do.

1. Collect Data

You need to collect data on your current audience before you do anything. You’ll want to start with a customer persona. Look at how they interact with your brand online:

You may need to run surveys, polls and customer research to find out more about your audience. However, most questions can be answered by playing with your Google Analytics accounts.

Once you have an idea of where your audience currently is, you can work out how to improve.


Now have a look at your pages in your analytics software around these assumptions:

2. Defining your goals

Your second step is to define your goals. More importantly, “What does success mean to you”.

Most businesses will have predefined business goals, but how do these tie in to your A/B testing?

Your goals need to be SMART goals:

A goal of “make more money” isn’t a good goal. It doesn’t explain how much is more. It doesn’t have any end date. Goals that are too vague are less likely to be achieved. This would be a better goal:

“Increase annual turnover by 15% by December 2020.”

Write down one, two or three goals that you want to achieve with your split testing. Ome example goals are:

3. Define Hypothesis.

Now you have your audience and your goals, it’s time to work out your hypothesis.

Your hypothesis is made up of two things:

Let’s say you have spotted a mass exodus on all category pages, but your product pages are converting well. Your category pages might not be clear for customers and that is affecting those customers from clicking through to the products they need.

You should run a user research to try to determine why someone wouldn’t click through to the product. If that isn’t an option, brainstorm ideas with your team, family, friends, and others to gather a list of  ideas of how to improve.

You work out from this data what steps you can take. 

In this example, tests proved that the products needed to look more clickable. So, the marketing team might want to set up your split test with a CTA button.

4. Create Variations

You will need to grab some A/B testing software unless you have a super-duper developer who can create the system themselves. Software varies from free to very expensive, but the more you spend, the more options or support you get. It’s best to have a look around to see your options.

You could run three pages for your button test:

Your metric for success is:

Once you have all these up and running, it’s time to get going.

5. Run Your Test

Once you are ready to, you can start running your tests.

Your variation will be sent to random users, and the software will start to collect data.

You will need to run your test for a long enough time that you get enough data to make a decision. Ideally, you should have at least 1000 people go through your test.

6. Analyse the results

Gather all the results from your tests. More expensive software will help you determine the winner. You’ll need to check the statistical significance of the results.

For example, let’s say we got the following results

Although Variation 2 showed definite increase in conversion, in reality, that’s only an increase of 6 people. This could just be an anomaly, those 6 people may have had the intention to buy then and there regardless of which test they saw. However, let’s say we had 100,000 people going through that test, you now have a difference of 600 people, which is much less of a coincidence.

If we had these results instead:

The difference between the control and variation 2 is a far more significant jump, in both percentage and the number of people converting.

What Is A/B testing in Digital Marketing?

Digital Marketing is all about results. 

Your boss wants to see an improvement in campaign results year on year. This could mean more sales, more followers on social media or more visitors to a website. 

With A/B Testing you can run variations of different social media statuses, email subject lines or landing pages in order to see which ones perform the best.
