How to use targeting filters to customize contexts in the Manager

This article explains how to customize context definitions by adding targeting filters in the Manager.

Experiment-level audience filters determine which users are eligible to confirm into an experiment, see treatment renderings and potentially reach the defined KPI(s). Content-level filters do the same but at a more granular level. They also have the advantage of being added, modified or removed without forcing a restart of a running experiment.

You should always consider the impact that context changes could have on your project's performance. Consider starting a new project version if your audience or conversion rate could be impacted.

1. Open the Manager.
2. Select a Project from the Universal Nav or the Projects list:
   
3. Once in the Project's draft tab, switch to the Variants tab in the left navigation column and select the Context to which you'd like to add filters:
   
4. In the Context panel, under Targeting Criteria, note the default web.url target criteria. To add a new filter, click the + icon as shown in the screenshot below:
   
5. The filter choices are Default attributes, Custom attributes or previously defined audience filters as defined in the Audience section of the Manager.
   1. Default attributes are a collection of pre-defined filters such as device type, platform, geolocation and browser. See Creating Audiences in the Manager
   2. Custom attributes are freeform keys and values, set in the environment configuration and based on runtime variables available to the Asset Manager from the target website via the client device. See How to Build Custom Audiences.
6. Once you have finished building your audience filter in the Targeting Criteria section, click Save. Once you deploy your project, your audience filter will apply to the context you specified.

Note: unlike the experiment' Audience filter, you can modify your context and variable Targeting Criteria without triggering a restart.
