Identify your Data Sources

A centralized business intelligence tool that collects and pulls automated reports from all data sources within the ad serving cycle is highly recommended. If you prefer to utilize your own inhouse setup to review performance here are some sources to identify for your KPIs.


Sample Metrics

Internal B.I. Tool
Supply Partners
Unique Visitors, Page Views
Delivery and performance of ads delivered via adserver
Delivery and performance of ads delivered via your webserver
Delivery and performance of ads delivered via Ad Exchanges
Number of campaigns and booked impressions

Automate Data Collection (Reports)

Creating automated reports has the purposes of saving time and producing consistent data while avoiding discrepancies as much as possible.
When juggling with multiple data sources, creating manual reports can lead to pulling different criteria from the same metric every time and therefore obtain inaccurate data. Here are some things to consider while creating automated reports:

  • Reports on metrics are always pulled from the same data source.

  • Always use the same criteria while creating/updating reports.

  • Ad Inventory needs to be properly labeled and segmented into placements that mirror your products and
    different audiences.

  • Compare results of metrics that could be obtained from more than 1 source to double-check their accuracy.

Interpret Data to Take Action

  • Wrong assumptions can lead to wrong decisions. For example - decreases in delivery will not necessarily result in a decrease in revenue and vice-versa.

  • Avoid weak assumptions by linking your Macro-data (metrics typically reported on High-level KPIs) to your Micro-data (metrics typically reported on the bottom line KPIs) to identify meaningful correlations between your data points.


  • Keeping two different sets of KPIs might allow you to keep a clearer perspective.
