|---|---|---|
| Decision validation | “Is [product] worth the price?” | Buyer’s remorse trigger |

| Troubleshooting | “Why isn’t [feature] working?” | Support deflection |
| Comparison regret | “[Product] vs [competitor] review” | Loyalty threat |
Why this matters:
43% of purchase decisions are influenced by AI recommendations.
That influence doesn’t stop at purchase. Customers continue consulting AI about their decisions.

If we don’t actively manage this:
AI might tell our customers:
Post-purchase content strategy:
| Content Type | Purpose | Example |
|---|---|---|
