The same shape on every platform. A field a platform does not have is null, and meta.unavailable says why. Use fields= to keep only what you need.

| Field | Type | Description |
|---|---|---|
| `keyword` | string | The related keyword. |
| `related_to` | string | The keyword asked about. |
| `relation` | string \| null | How it relates: searched together (query), appears together in content (posts), searched before (prior) or after (after), or suggested as you type (suggestion). |
| `rank` | integer \| null | Position among the keywords of the same relation, from 1. |
| `relevance` | number \| null | How closely it is related, 0 to 1. |
| `search_index` | integer \| null | Its search index (the platform's measure, not a count); null where the platform gives none. |
| `composite_index` | integer \| null | Its composite index (the platform's measure of attention, not a count). |
| `ext` | object | Platform-specific extras. Only returned with view=full. |
