Fill in the blanks: ______ is a broad term with high traffic and lots of competition. ______ is a phrase with the lowest amount of traffic and moderate competition. ______ is the most focused term with lowest traffic and competition.

The correct answer is Fat head, chunky middle, long tail. "Fat head" keywords are broad, high-volume terms with significant competition. "Chunky middle" keywords are more specific than fat head terms, having moderate traffic and competition. "Long tail" keywords are highly specific phrases with the lowest search volume and competition, often representing niche queries. The other options incorrectly assign these definitions to the different keyword types.
