Review platforms have long been considered a customer experience tool. In the GEO context they gain an additional dimension: they are a source of training data for AI models and an off-site authority signal.
How do AI systems use review data?
AI models are trained on extensive text corpora, including publicly accessible review platforms. What users write about your brand on Trustpilot or Google Reviews contributes to the picture AI models have of your brand — not only quantitatively but also qualitatively.
Implications for GEO strategy
Reputation management as GEO factor
A neglected Trustpilot page with outdated, negative reviews is not only bad for your conversion rate — it is also a negative signal for AI systems.
Terms and entities in reviews
Reviews containing product-specific terms reinforce the association of your brand with those terms in AI training data.
External platforms as authority amplifier
Presence on multiple trusted external platforms strengthens the off-site authority signal.
Which platforms to prioritise?
- Trustpilot: broadly recognised, high trust, publicly accessible
- Google Reviews: direct integration with Google ecosystem and Gemini
- Sector-specific platforms and comparison sites
- LinkedIn: professional reputation, relevant for enterprise AI usage
