A/B testing is key to improving results in any marketing campaign. We examine the issues involved in its 3 main components: message variants, user group selection, and choosing the winning version.

The primary aim of any marketing campaign is to effectively engage with the target audience and encourage them to perform the desired set of actions.

To deliver an effective marketing campaign, a marketer requires 3 key things:

1. A target audience
2. An effective message
3. A means to evaluate the campaign’s result

Generally, a lot of time and effort is spent on identifying the audience. A relatively less effort is spent on creating an effective message and even lesser effort is focused on evaluating the results. An ideal target audience and a poor messaging will mostly likely result in poor results. Hence, the importance of an effective message cannot be understated. But, creating an effective message is highly subjective in relation to the other two points. Therefore, it is imperative to use a technique that helps the marketer to quantify the impact of available choices. The choices may range from content, aesthetics, emojis, subject lines, etc. Generally, the choices are distinguishable but sometimes even subtle changes might result in a dramatic shift in outcomes.

For example: We have observed that for similar campaigns, by using the word ‘cashback’ instead of ‘offers’, the CTRs increased by almost 15% to 20%.

Given couple of messaging choices, marketers often resort to A/B testing to select the best choice.

What is A/B Testing?

Consider A/B testing as an experiment where two variants of a message are shown to 2 different groups of users. These groups of users comprise of a small proportion/sample of the entire target audience.
After running the experiment, the marketer selects the best message based on CTRs, conversion rates or other actions performed.

Put simply, the A/B testing can be broken down into 3 parts, viz., message variants, selection of user groups and choosing the winning variant. Let’s delve into each part in greater detail with the help of an example:

Suppose you are in charge of creating a push notification campaign for a product with a discount offer. You have at your disposal the target audience of 100,000 and the design templates of the push notifications.

Top 10 Machine Learning Videos

Learn data science through hands on problems

Introduction

As part of DataFest 2017, we launched a new initiative – DataHack Hour. DataHack Hour was inspired by numerous queries we get related to learning Data Science. Questions like “How to learn analytics?” or “How to become a data scientist?” are asked to us multiple time every day.

While we had written several articles on this subject on Analytics Vidhya – we needed something more definitive to answer these queries. In order to answer these queries, we decided to create an experience to show people how to learn Data Science. This version of DataHack Hour is our answer to the above questions or many more questions which come to us.

A Complete Tutorial on Tree Based Modeling from Scratch (in R & Python) from analytics vidya

Introduction

Tree based learning algorithms are considered to be one of the best and mostly used supervised learning methods. Tree based methods empower predictive models with high accuracy, stability and ease of interpretation. Unlike linear models, they map non-linear relationships quite well. They are adaptable at solving any kind of problem at hand (classification or regression).
