    Automated IAB Content Taxonomy Classification for Contextual Targeting

    For DSPs processing 50M+ bid requests per day. Automate IAB 3.0 taxonomy classification for video and display ads with 94% accuracy and sub-second latency.

    Who It's For

    DSPs and SSPs processing 50M+ daily bid requests requiring IAB Content Taxonomy classification for contextual targeting

    Problem Solved

    Manual content categorization cannot scale to bid stream volumes, third-party cookies are disappearing, and generic categories provide insufficient targeting precision

    Why Mixpeek

    94% classification accuracy across all tier levels, sub-second API latency for real-time bidding, and continuous model updates as IAB taxonomy evolves

    Overview

    The deprecation of third-party cookies has made contextual targeting the primary alternative for privacy-compliant advertising. IAB Content Taxonomy 3.0 provides a standardized framework with 700+ categories, but manual classification is impossible at programmatic scale. This use case shows how Mixpeek enables automated, accurate IAB taxonomy classification for millions of ad placements daily.

    Challenges This Solves

    Third-Party Cookie Deprecation

    Chrome and Safari cookie restrictions eliminate traditional behavioral targeting methods

    Impact: 60-70% reduction in targetable inventory using legacy methods, forcing shift to contextual

    Manual Classification Impossible

    DSPs process 50M+ bid requests daily, each requiring content classification

    Impact: Manual tagging would require thousands of humans and introduce multi-day delays

    Multi-Tier Taxonomy Complexity

    IAB 3.0 has 3 tiers and 700+ categories requiring nuanced understanding

    Impact: Simple keyword matching achieves only 40-60% accuracy, missing contextual nuance

    Video Content Complexity

    Video ads require analyzing visual scenes, spoken audio, on-screen text, and brand context

    Impact: Point solutions analyzing only one modality miss critical classification signals

    Implementation Steps

    Mixpeek automatically classifies video and display content into 700+ IAB 3.0 categories using multimodal analysis of visual scenes, audio, text, and context

    1

    Configure IAB Taxonomy Extractors

    Enable Mixpeek IAB Content Taxonomy classification models

    // Configure IAB classification
    const iabConfig = {
      extractors: ['iab-taxonomy-tier1', 'iab-taxonomy-tier2', 'iab-taxonomy-tier3'],
      return_top_n: 5, // Return top 5 categories per tier
      min_confidence: 0.70
    };
    2

    Process Video Ad Creative

    Submit video creatives for multimodal IAB classification

    async function classifyCreative(videoUrl: string) {
      const result = await client.extract({
        url: videoUrl,
        extractors: iabConfig.extractors,
        metadata: {
          creative_id: 'ad_12345',
          advertiser: 'Brand X'
        }
      });
    

      return {
        tier1: result.extractors['iab-taxonomy-tier1'].slice(0, 5),
        tier2: result.extractors['iab-taxonomy-tier2'].slice(0, 5),
        tier3: result.extractors['iab-taxonomy-tier3'].slice(0, 5)
      };
    }
    3

    Integrate with Bid Stream

    Pass IAB categories to bidding logic for contextual targeting

    // Use IAB categories in bid decisions
    async function evaluateBid(bidRequest) {
      const placement = bidRequest.placement;
      const creative = bidRequest.creative;
    

      // Get placement content categories
      const placementCategories = await getPlacementCategories(placement.url);
    

      // Get creative categories
      const creativeCategories = await classifyCreative(creative.url);
    

      // Match Tier 2 categories for contextual relevance
      const categoryMatch = matchCategories(
        placementCategories.tier2,
        creativeCategories.tier2
      );
    

      if (categoryMatch.score > 0.8) {
        return { bid: true, bid_amount: calculateBid(categoryMatch.score) };
      }
    

      return { bid: false };
    }

    Cache Classifications

    Store IAB classifications for reuse across campaigns

    // Cache creative classifications
    await client.metadata.update({
      collection_id: 'video-ads',
      object_id: creativeId,
      metadata: {
        iab_tier1: result.tier1,
        iab_tier2: result.tier2,
        iab_tier3: result.tier3,
        classified_at: new Date().toISOString()
      }
    });
