To carry out A/B Testing, 7 steps need to be put in place:

‍Identify the objective to implement your strategy: Before taking action, clearly define the objective of your A/B Test. This may include, for example, increasing the e-commerce conversion rate, reducing the Abandon cart, generate qualified leads, reduce the bounce rate, or even optimize or implement cross-selling and upselling.

‍Define the variations of your A/B test: Then decide Variations you want to test. For example, you can change the color or font of a CTA (i.e. a button), create a new version of your home page, or even modify certain visuals according to the visitor's intent.

‍Select sample: In A/B testing, choosing the target sample is absolutely essential, and should be in line with your objective. For example, you can choose to launch your A/B Tests only on mobile visitors to your e-Commerce site, or rather on 100% of your traffic in order to obtain large-scale results. Be careful all the same to don't stray too far from customer journeys that you usually offer. Excellent A/B testing is also a test whose results can be interpreted in a clear and unbiased manner.

‍Design your A/B Test: Then create Variations in content that you want to test, then divide them into test and control groups randomly in order to get the best results and draw the most accurate conclusions from your A/B Testing.

‍Run the A/B Test: To successfully carry out your A/B Testing project, launch your test by setting up a tracking of the results of each test and control group over a determined period of time.

‍Analyze the results: Collect the data of your A/B Testing campaigns, then proceed to the analysis of the results to determine if the tested version has a significant impact on the initial objective of your A/B Test, and if it confirms the hypotheses put in place beforehand.

Applying the findings: Once the A/B Test is over, you can use your results and conclusions to implement the most optimized version of the item you analyzed, whether it's a web page, an e-mailing campaign or even an advertising insert.

To interpret the results of an A/B Test, you can rely on these 6 elements:

‍Statistical significance: Before analyzing them, you need check if your tests are relevant. Indeed, the differences observed between the two variants must be the result of the change in the variable tested. To check this, you can use statistical tests such as the Student test (t-test) or the chi-square test.

‍Sample size: The larger the sample size of your A/B Test, the higher the probability of getting meaningful results. Remember to check that the sample size is sufficient to obtain the most reliable results possible.

‍Key performance indicators (KPIs): KPIs are the metrics you have chosen to measure the impact of the tested variable on your performance. So you need select relevant indicators, then analyze the results according to these KPIs to determine which variant generated the best performance.

‍Consistency with the hypotheses: It is appropriate to check if your results are consistent with the initial assumptions. If these don't match the assumptions, try re-examining the data or revising your assumptions to understand why the results were different.

‍Duration of the test: Ensure that the test is conducted during a sufficiently long period to obtain relevant and significant results: in fact, if the test was too short, the results might not be reliable. So, you will have to continue with your A/B Test.

‍Market knowledge: Finally, take into account the fact that your results may be influenced by external factors : market trends, competitive actions, seasonality,... These aspects must also be taken into account when interpreting the results.
