Zero-waste solid oral care. Personal care. United States. 90 days.
How a zero-waste oral care brand won AI answers for enamel-rebuilding toothpaste tablets
Eco D2C and Amazon US. Engines monitored:
The challenge
Shoppers asking "best non-toxic toothpaste tablets for sensitive teeth that rebuild enamel" were shown old fluoride-free pastes with poor remineralization credentials. The client's nano-hydroxyapatite formulation was routinely overlooked.
What the audit found
Every engagement starts with a baseline across a fixed set of buyer prompts.
- Hydroxyapatite particle concentration (percentage and synthetic purity) was missing from crawlable text.
- Amazon listing attributes for active ingredients remained blank.
What we did, stage by stage
Using the EASY framework: Entity, Answers, Sources, Yield.
Entity
Populated all personal care chemical profiles across Amazon backend tables; linked active ingredient schema to peer-reviewed dental literature.
Answers
Built a clinical Nano-Hydroxyapatite vs Fluoride Enamel Remineralization Primer highlighting clinical safety, RDA abrasivity scores and sensitivity mechanics.
Sources
Sourced expert reviews from progressive biologic dentists; engaged in eco-friendly dental discussions.
Yield
Tracked 30 prompts targeting tooth sensitivity and zero-waste oral health; correlated engine pickup with rising Amazon conversion metrics.
Results after 90 days
Baseline measured before any changes, against the same prompt set, engines and locations.
| Metric | Baseline | After 90 days |
|---|---|---|
| Eco personal care share of voice | 3% | 23% |
| Remineralizing toothpaste tablet prompts captured | 1 of 30 | 11 of 30 |
| Monthly attributed D2C and Amazon revenue | $2,100 | $18,400 |
| Active ingredient (nano-HAp) fact accuracy | 54% | 93% |
What worked, and what did not
Emphasizing plastic-free packaging alone failed to win AI answers. Explaining the clinical enamel-rebuilding mechanism with exact compound data drove algorithm picks.
