What makes this a useful free keyword research tool?

It combines seed keyword metrics with related keywords and People Also Search For data so you can go from one idea to a prioritized list quickly. That makes it useful for finding adjacent opportunities, not just checking one keyword in isolation.

How should I interpret the opportunity score?

The opportunity score is a simplified blend of search demand, CPC, and estimated difficulty. It is meant to help you compare ideas quickly, not replace a full SERP review. Use it to narrow the list, then inspect intent and ranking pages before committing.

Does this tool replace full content strategy research?

No. It is best for quick expansion and prioritization around a seed term. For a real strategy, you still need clustering, intent review, business fit, and a page-program decision.

What is the difference between related keywords and PASF keywords?

Related keywords are semantically adjacent queries around the seed. PASF keywords come from the People Also Search For layer and often reveal neighboring intent, modifiers, or alternate phrasings worth building around.
