About this model
Related Keywords mines a deep keyword graph to uncover terms that are semantically related to a single seed keyword, rather than just lexical variations of it. A configurable depth parameter (1-4) controls how many hops the search tree expands, so shallow requests return close synonyms while deeper requests surface adjacent topics a searcher might explore next. Each result includes search volume and keyword difficulty, which makes this endpoint useful for building topic clusters and finding long-tail content angles competitors haven't covered yet.
