Step 3: Set Targeting (optional)

Hackle provides the ability to limit and customize users who participate in A/B testing. For example, the A/B test targeting rules can be set so that only Android users among mobile operating systems are allowed to participate. However, users who are manually allocated to a certain test group cannot be subjected to targeting. For more information on manual allocation, please check out Step 7: Register Test Devices for Manual Allocation(optional)

(Note) Users participating in an A/B test are subject to traffic allocation. For more information, see the Traffic Distribution document.

Conditions for using the targeting function

Check your SDK conditions

  • Supported languages for targeting: Android, iOS, JavaScript, React, React Native, Java/Kotlin, Python, Node.js
  • Supported versions for targeting: iOS and React Native are 2.0.0 or higher, others are 2.1.0 or higher
  • For more information about SDK versions and their functions, refer to the What is a SDK? document.

Check your plan

  • Targeting is only available for paid plans (Pro plan and above).

Policies to follow

  1. When to set

When the experiment is in Draft mode. Targeting rules cannot be edited once the experiment starts.

  1. Default

If you do not set a target, all users will participate in the A/B test.

  1. Environment

Can only be set in Production Environment.

  1. Target Rule

If you want to limit your audience to specific users, you need to start with at least 1 target rule.

You can have up to 10 target groups for an A/B Test. All target rules are subjected to an OR operator so that the user becomes the targetted user only if one of the target rules is satisfied.

For example, if we want to target users who observe at least one quarantine measure in a situation where they receive a questionnaire about compliance with quarantine rules, "users who use a new mask every day", "users who use hand sanitizer frequently", "users who frequently use soap and wash their hands", you only need to satisfy one of the rules.

  1. Conditions

A target group will have at least 1 condition from the point that it is created, and you can have up to 10 conditions within each target rule.

Each condition will have the AND operator applied and the targeting will only occur for a user that has all of the conditions satisfied.

For example, if you target Android users among mobile operating systems and users in their 30s, both the conditions "users with Android mobile operating systems" and "users in their 30s" must be satisfied.

Hence depending on your needs, you will either add a target rule or a target rule condition within a target rule.

  1. Property

Target Groups rules and conditions act on the pre-determined properties. Therefore, you should first integrate with the Hackle SDK and be able to collect the property keys and values to use.

For more information about properties, see the Properties document.

Composition of target rules and conditions

πŸ“˜

Important!

Both the target rules and conditions consist of a combination of property name + operator + property value.

For example, if you want to target Android users among mobile operating systems in a situation where users' operating systems are being collected via the property key osName, you can create the following combination.

  • Property Key: osName
  • Operator: One of the following
  • Property Value: Android, android

The first combination created becomes the first (target) rule. Depending on whether you add another combination as an AND or an OR to these rules, you can create a target for a completely different user.

Let's take a closer look at the operators and AND/OR below.

Operator

Operators are used when setting conditions and serve to describe the relationship between property names and property values.
Hackle provides a total of 22 operators, you must select an appropriate operator according to the type of property value of the selected property name.

Please refer to the table below for more details.

Example

If you want to target users who live in a metropolitan city, as long as the user is living in one of the six metropolitan cities, you can define the following rule like this:

πŸ‘

Creating a rule for [users residing in a metropolitan city]

  • Property key: Region (The property value of the region is String type)
  • operator: one of the following
  • Property values for 'next' spoken by the operator: "Dallas Metropolitan City", "New York Metropolitan City", "Los Angeles Metropolitan City", "Chicago Metropolitan City", "Houston Metropolitan City", "Washington Metropolitan City"

AND and OR

The two AND and OR operands have the following meanings:

  1. AND
    Both operands must be satisfied to be included in the targetted users.
    For example, if 'Android users among mobile operating systems AND users with addresses in Seoul', only users with addresses in Seoul ** among users using mobile devices with Android operating systems are targeted.

  2. OR
    If only one of the operands is satisfied, it is included in the targetted users.
    For example, if 'Android users OR address in Seoul among mobile operating systems', users who use mobile devices with Android operating system or users whose address is in Seoul are targeted.

πŸ“˜

AND and OR operands in Hackle's targeting

  • The AND operator is used when adding conditions to a rule. Since multiple conditions must be satisfied to be included in the target, the more AND operator is used, the narrower the target's scope.
  • The OR operator is used when adding a rule. The more you use the OR operator, the wider the target, because if only one of the rules is satisfied, it is included in the target.

Setting up targeting rules on the dashboard

When creating A/B tests

You can set a target when creating a new A/B test.

🚧

You don't necessarily have to set it up during the step you create your A/B test!

You can set the rules after creation or change what you set up from the initial stage.

On the Create A/B Test screen below, you will find Audience Targeting at the very bottom.
The default is set as All users.

16361636

By pressing the + Add Target Rule button, you can set the first condition of the first rule as shown in the screenshot below.

12921292

The values to input or select and the description of each button are as follows.

  1. Property key
  2. Operator

  3. Property value
  4. Delete rule
  5. Add an AND condition
  6. Add new rule

If you click the + Add an AND condition button in 5, a condition is added to rule 1 as shown in the screenshot below,

12741274

Then click the + Add New Rule button 6 to add Rule 2.

12821282

As mentioned earlier, a single target rule can have up to 10 conditions, and your actual targeting can have up to 10 rules.
Don't forget that it's the AND operator when adding conditions, and the OR operator when adding rules.

After entering the necessary information to create the test and setting the targeting settings, click the Save button to complete the setup.

View settings in dashboard

You can view A/B Test targeting setup information in the upper common area of ​​the A/B Test Details.
However, target setting and setting changes are possible only in the ready state, so there is a slight difference in the contents displayed depending on whether the A/B test is in preparation or otherwise.

No target rules set (0 rules)

If you don't set a target, i.e. if the rule is 0, you don't restrict users to participate in A/B testing, so you're targeting all users.

when the A/B test status is in Draft mode

β‘  shows that the targeting is applied to all users.
You can set the target through the Target setting button in β‘‘.
You can see an example rule in β‘’. This is not a real rule and is just an example of what it would look like when you set up a rule.

If the A/B test status is running

19581958

β‘  shows that the experiment is for all users.
However, there is no additional information to show because target setting is not possible.

Set target (1 or more rules)

If the target is set, it has at least one rule because it limits the users who will participate in the A/B test.

when the A/B test status is in Draft mode
