| Figure | Where it comes from |
|---|---|
| Opportunity score | AltFTool editorial judgement on a 0-100 scale. It is not measured, not audited and not a prediction of commercial success. |
| Monthly search | A directional third-party estimate where one is recorded. Where none is, the figure reads "Researching" rather than showing a made-up number. |
| Competition and momentum | Editorial labels, not metrics from an SEO platform. |
| Relative search interest | The only live figure on this page. It is fetched from Google Trends when you load the page and is a 0-100 relative index, not absolute volume. |
