Expand any seed keyword into hundreds of real YouTube search suggestions and score each one by competition - result count, top-10 views, freshness and opportunity score.
A YouTube keyword research connector that expands one or more seed keywords into large sets of real YouTube search queries using YouTube's autocomplete service and multiple expansion methods (direct suggestions, alphabetic expansion, question/modifier expansion). For each suggested query the connector optionally measures competition by scraping the current top results and computing demand and competition metrics: estimated number of competing videos, aggregated top-10 view statistics (average, median, min, max), count of recent top results (freshness), count of distinct channels in top positions, proportion of Shorts in the top results, and metadata for the top video and the top-results list. These signals are combined into a single 0–100 opportunity score that balances demand, competition and freshness. The connector supports market targeting by country and language and can run as suggestions-only or include full competition measurement.

| Field | Type | Required | Description |
