Why do I need A/B test? 10 reasons why you must do split testing

Whenever you have to make a decision, you want to compare cases and choose the better one. You may do it by tossing a coin, intuition, common sense, or other unreliable way but it’s better to use your data.

10 reasons why A/B split testing is necessary:

1. You cannot believe in your intuition

Many studies showed that common sense or intuition may be misleading. Human brain is just not good enough at making the perfect decision. It’s good at making fast decisions.

2. You have to confirm your opinion

Many times you are asked whether you think case A or case B will be better. You may say that “just because I think so”, or “I guess I’m competent enough”, or “Not sure”, but these expressions sounds silly. The best is when you can support your opinion by numbers.

3. You want to eliminate the effect of randomness

Sometimes it’s obvious that case A or B is better. But what if the result happened only by coincidence? Maybe it’s just random noise… How could you be sure about the result? This is what A/B split testing is good for.

4. Money matters

If you have a website where you sell a product or a service, you want to maximize your profit. And not just once. You want to get more money in every month. You want to achieve continuous growth. The only way of doing this is to constantly experiment.

5. Time matters

You don’t want to argue, debate, search for arguments, or just thinking for hours. It’s just much simpler if you use your data and run an A/B split test.

6. Choosing the wrong case might be painful

Sometime it’s doesn’t matter whether you choose A or B. But in most of the cases, it’s very painful if you take the wrong decision. Solution: A/B split test.

7. You want to know the exact difference between case A and B

If you look at the conversion rates, sometimes it’s obvious if A or B is the right choice. But A/B split testing can show you the minimum and maximum difference between the cases.
So, for example, it tells you: It’s sure that A is better by at least 6%, but not better than 9%.

8. You want to automate decision making

Continuous decision making costs a lot of money, time and effort. If you automate your processes you can concentrate on your business. Unlike human decisions, A/B split testing can be automated so your life will be better.

9. Knowledge is power

Data is the new raw material, and information is power. You have so much information in your data, so you cannot allow yourself not to know everything.

10. A/B testing is fun

If you start to A/B test everything, you will get interesting, useful and sometimes funny results.
