Props are custom variables that you can use however you’d like. They do not persist beyond the hit that they are set.
Adobe recommends using eVars in most cases. In previous versions of Adobe Analytics, props and eVars had advantages and disadvantages to each other. However, Adobe has improved eVars to where they fulfill almost all use cases for props.
If you have a solution design document, you can allocate these custom dimensions to values specific to your organization. The number of available props depends on your contract with Adobe. Up to 75 props are available if your contract with Adobe supports it.
Each prop collects data from the
c75 query string in image requests. For example, the
c1 query string parameter collects data for prop1, while the
c68 query string parameter collects data for prop68.
prop75. See prop in the Implement user guide for implementation guidelines.
Since props contain custom strings in your implementation, your organization determines what the dimension items are for each prop. Make sure that you record the purpose of each prop and typical dimension items in a solution design document.
Props, by default, are not case-sensitive. If you send the same value in different cases (for example,
"Dog"), Analysis Workspace groups them together into the same dimension item. The case of the first value seen at the beginning of the reporting month is used. Data Warehouse shows the first value encountered during the request period.
You can make any prop case-sensitive. You can also disable case-sensitivity for any prop once it is enabled. Contact Adobe Customer Care with the report suite ID and the desired variables(s) to toggle case sensitivity.
Toggling case sensitivity can cliff dimension items, causes unexpected results with segments, and causes issues with filters. Adobe strongly recommends toggling this setting between two major time periods, such as the beginning of a month or year.
Adobe recommends using eVars in most cases. Exceptions to this statement are as follows:
See eVar for more comparisons between props and eVars.
