Key Takeaways & Executive Summary
Over 38% of consumers who view a paid social ad consult an AI assistant before completing their purchase.
Last-click attribution models fail because they attribute the conversion either solely to direct navigation or to the final query.
AntraAI smart vanity URLs with persistent UTM cookies capture the complete journey from initial ad impression to conversion.

1. The Non-Linear Customer Journey in 2026

The modern buyer's journey is no longer linear. A shopper sees a video ad for your product on Instagram or TikTok while commuting.

Instead of clicking immediately, they open ChatGPT or Perplexity later that evening and ask: 'Is [Brand Name] worth the money? What are the common complaints?'

The AI answers, citing third-party reviews and your official product documentation. The customer clicks the cited link, completes the checkout, and your traditional ad dashboard reports zero return on ad spend (ROAS).

“If you only measure direct ad clicks, you are drastically undercounting your best-performing creative campaigns.”

2. Setting Up AntraAI Unified Attribution

With AntraAI, you deploy branded smart links across all ad campaigns. When users engage, AntraAI fingerprints the session and tags the visitor with deterministic campaign parameters.

When the customer subsequently searches or enters via an AI citation, AntraAI connects the edge telemetry, linking the ad spend directly to the downstream conversion.
