Every form submission, in the person's own words, with where they came from. Label each one so tests are judged on good leads, not just more leads.
“Do you have the adjustable base in a king in stock? Want to try it in store Saturday.”
“Is financing available on the hybrid mattress? Looking at about $1,800.”
The AI labels every lead. “Needs review” means it was unsure, so a person decides; anyone can change any label. The AI reads the answers only, never names, emails or phone numbers.
