GA4 is a free web analytics tool focused on traffic analysis: pageviews, sessions, user behavior. TrustData is an independent marketing measurement platform focused on attribution, AI visibility, and budget optimization. Many brands run both: GA4 for web analytics, TrustData for marketing measurement.

TrustData uses first-party server-side tracking loaded from your own domain, which bypasses all three of these blockers.",{"question":404,"answer":405},"Does GA4 have AI visibility monitoring?","No. GA4 does not monitor how your brand appears in AI-generated answers from ChatGPT, Gemini, Perplexity, Claude, or other AI search engines.

When Google Ads and Meta Ads both claim credit for the same conversion, TrustData cross-references them against your Shopify orders or CRM data and assigns one deduplicated credit.
