Adobe AD0-E213 - Adobe Analytics Developer Professional Exam

A random number data element is often used for sampling data in the Adobe Experience Platform. This data element generates a random number between 0 and 1, which is then used to select a given sample size. This is referenced in the Adobe Analytics Developer Professional study guide section on the Tag Management System.

Rules in Adobe Experience Cloud enable developers to control the what, when, where and how of all the analytics tags on the website. Rules allow you to easily create and manage analytics tags using point-and-click interfaces. Rules also allow you to create conditions so that certain tags will only fire when certain criteria are met, giving you more control over the data that is collected. Rules are a powerful tool for developers, allowing them to customize the analytics tags for a website quickly and accurately.

Authors can use nested launches to avoid repetitive work in various places of their websites. A nested launch is a launch that is created inside of another launch, and can be used to share common settings between multiple launches. For example, if an author needs to use the same set of rules in multiple places of their website, they can create a single launch with those rules, and then nest it inside of other launches that need to use those rules. This is an efficient way of avoiding having to repeat the same work in multiple places.

The first step for data to get from the developer's page into the reports in Adobe Analytics is for the analytics code to be served via the data layer and Adobe Launch. This allows the page to collect andsend data to the Adobe servers, which then processes the data and saves it into the designated report suite. This data is then used to generate reports that are available to view in the Adobe Analytics interface.

According to the Adobe Analytics Developer Professional study guide, query string parameters are used in the Adobe Experience Platform to identify search terms on a retail website. Query string parameters are the portion of a URL that follows the question mark (?) and contains key-value pairs that provide additional information about the request. For example, a URL containing a query string parameter might look like this:www.example.com/search?term=shoes. In this example, the query string parameter is "term=shoes", which indicates that the search term being used is "shoes".
