Impressions and conversion tracking help measure PPC when clicks miss AI-driven influence

Key points

• Impressions show ad exposure, including in AI answers, but cannot be perfectly mapped to individual AI interactions.
• Microsoft Advertising impression-based remarketing can target users by whether they saw an ad, if eligible campaigns are set up.
• Platform conversion data should be checked against CRM, ecommerce, and sales records to catch duplicates and gaps.
• Consent and tagging audits explain incomplete visit data, but do not explain interactions that never produced a site visit.

Why it matters for marketers: Marketers should pair impression trends with branded search, direct traffic, and CRM outcomes rather than judging PPC on clicks alone.
