The base library is the first magical step to begin basic CHEQ data collection. Installing it via Adobe Launch simply requires a single rule that loads our JavaScript tag at the top of every page (if possible). You may already have an existing rule you want to add our library to. For the purposes of this guide, we assume you do not.
First, open your Adobe Launch property, navigate to Rules, and click Add Rule.
In the rule creation interface, click the + Add button below Events and add an Event to load on Library Loaded (Page Top).
| Field | Description | Example |
| Extension | Core Extension in Launch. | Core |
| Event Type (Recommended) | Tells Launch when/where the tag should be triggered. | Library Loaded (Page Top) |
| Name (Recommended) | Some name that makes sense. This doesn't impact functionality. | Page Top |
Click Keep Changes in the top-right.
While we recommend loading our tag as the highest priority and Page Top (Library Loaded), we also understand that there could be reasons that this isn't possible. This recommendation mitigates certain race conditions, but is not always required.
Next, click on the + Add button below Actions and add HTML.
| Field | Description | Example |
| Extension | Core Extension in Launch. | Core |
| Event Type | Sets the type of action that will be executed. | Custom Code |
| Name (Recommended) | Some name that makes sense. This doesn't impact functionality. Use all caps if you're really excited. | CHEQ Tag |
Next, click Open Editor and copy/paste the <script> tag.
Click Save, then click Keep Changes in the top-right. Finally, Save the rule. That's it!
What about the <noscript> tag?
Adobe Launch is exclusively a JavaScript-based tag and, as such, does not support <noscript>tags (the tag that detects users with JavaScript disabled). If your business use case requires capturing these users, consider deploying the <noscript> tag immediately after the opening of the <body> tag.
Next Steps
Now that you have the base CHEQ tag in place, it's time to start thinking about how you can enrich every step of your decision-making by setting your first-party IDs or sending our data directly to your analytics tool(s).
