Content 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 “IAB Tech Lab Content Taxonomy” was previously called the “Quality Assurance Guidelines (QAG) Taxonomy.”

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 IQG Program (formerly QAG Program) so that content classification can be consistent across the industry.
