Surfais measures how AI answer engines describe a brand. The product works in three stages.
| See | A defined prompt panel runs against five engines per country on a schedule. Every response is retained, and the brands and sources named in it are extracted. |
|---|---|
| Score | The AIS Score, a single figure out of 100, with published weights and a version number. |
| Fix | A prioritised audit across content, sources and schema, including ready-to-paste JSON-LD. |
All five are included on every paid plan. There is no per-engine add-on and no engine gating by tier.
| Headline metric | AIS Score, 0-100 |
|---|---|
| Current version | v2, adopted 10 June 2026 |
| Weights | Visibility 60%, Position 15%, Sentiment 10%, Share of voice 15% |
| Previous version | v1 weights were 45/25/15/15. v2 lowered scores shown to paying customers. |
| Mention detection | Entity resolution with a three-state verdict, adopted 18 August 2026, replacing a word-boundary string matcher |
| Published at | surfais.com/methodology |
The weights are published rather than proprietary, the score is reproducible from them, and every version change is dated and explained. The IAB's August 2026 framework describes measurement as decision-grade when it is reproducible, disclosed and versioned.
