What to expect
A list of real autocomplete suggestions ranked by opportunity. The tool mines Amazon and Google autocomplete recursively, scoring each keyword. You'll typically find 50-200 keywords from a single seed, organized into thematic clusters (audience, product type, format, use case).
Common issues
No results returned Try a broader seed keyword. Very specific terms may not have autocomplete suggestions.
Scores seem low Scores are relative. In competitive niches (e.g., "coloring book"), most keywords score 30-50. Look for long-tail keywords (4+ words) with scores above 40.
