IAB Quality Assurance Guidelines (QAG) Taxonomy

Contextual taxonomy was developed in consultation with taxonomy experts from academia, ad measurement companies, and members of the IAB Networks & Exchanges Committee. This taxonomy defines contextual content categories on at least three different tiers.

The first tier is a broad level category defined as a targeting depth of either: category/portal, site section, or page. Tier 2 categories and greater are additional categories nested under Tier 1 categories. Both tier 1 and tier 2 categories are formerly established for the QAG Program so content classification can be consistent across the industry.
