Targeting Visitor Groups

We can target a campaign for specific users of the app.
To do this, under Advanced Options of the Finalize step of campaign creation, select Enable campaign for a specific user group.

1352

You can target the app according to the following options:

  • iPhone Users
  • iPad Users
  • New Users
  • Returning Users
  • App Version
  • iOS Version
  • Day of Week
  • Hour of the Day
  • Country
  • Screen Width
  • Screen Height

Please note that all the above targeting options do not require any code changes.

If you want to do custom targeting such as running a campaign only for paid users of your app, then select Custom Variable.

Custom Variable

The Custom Variable field is useful when you want to target the campaign on the variables and conditions set by your code.
To use a custom variable, define a variable name and a corresponding value in the dashboard.
In your app code, set customVariables in VWOConfig before launching.

VWOConfig *config = [VWOConfig new];
config.customVariables = @{@"user" : @"paid"};

[VWO launchForAPIKey:@"<your-api-key>" config:config completion:^{
  //Code executed after launch is complete
} failure:^(NSString * _Nonnull error) {
	// Failure handling
}];

let config = VWOConfig()
config.customVariables = ["user" : "paid"]

VWO.launch(apiKey: "<your-api-key>", config: config
  completion: {
	   //Code executed after launch is complete     
	}, failure: { error in
      print(error)
})

When to set custom variables

  • If you have specified certain custom variables in the campaign, those values must be set in the code before calling the objectForKey:defaultValue: method.

  • If you have selected Make user part of the campaign on app launch in the VWO dashboard, then custom variables should be set before launching the SDK. This is required, because the SDK will try to make the user a part of the campaign on the app launch.
