Clarisights has two broad classes of data sources -
Primary Data - these are all of the standard and custom advertising channels, Google Search Console, and flat data sources (POD-AJ).
Secondary Data - these are typically the analytics sources like GA, Adjust, Appsflyer etc.
You might wonder if Adjust is a secondary data source, then what is POD-AJ (which is a primary data source)? To explain that, let's first look at the distinction between Primary Data and Secondary Data.
When Clarisights imports the data from a primary data source, we import all of the metrics and dimensions and store those in the database. Considering an example, here's some sample ad channel data of a hypothetical e-commerce store -
In this case, since this is a primary data source, the imported data on Clarisights would contain all of the above dimensions along with the metrics.
In the case of secondary data sources, when Clarisights imports the data, we do not store the dimensions from these sources, but instead use them as joining keys to join the data to the respective primary data source.
For example, in the case of Adjust, we have tracker based joining with the advertising channels. That means, once Adjust data is imported, the above dataset would look like this -
As you would notice, the AJ dimensions like are not available on Clarisights. Only the metrics from AJ are available that are joined with the dimensions from respective ad channels like Adwords, Facebook, Twitter, etc.
This is also the reason why "Adjust" is not a separate data source when you're creating reports; its metrics are automatically included when an ad channel with which it is joined is added to the report.
Also note that the logics for joining AJ metrics to the ad channels are built into Clarisights; and we add to these logics whenever a new ad channel connector is made available. The way this logic works is currently not customizable per customer.
Okay, now we know what is Adjust on Clarisights. Then what is POD-AJ?
There are lots of scenarios when you might actually need Adjust dimensions on Clarisights. You might want to look at organic traffic, affiliates traffic etc. which are not joined to any specific advertising channel (and are thus not available in the 'AJ' metrics). You might want to track data of an affiliate who sends clicks to your website through specific network tracker. These are all use cases when you need to independently look at dimensions like network, country, OS etc.
For this purpose, in Clarisights we have "Adjust" as an option under the sources from which a POD can be created.
In conclusion, Adjust is data that's joined to primary data sources, and thus only contains metrics and no dimensions of its own. On the other hand, POD-AJ is data that is a primary data source; is customizable and has its own dimensions and metrics.
