Frequently Asked Questions
Can I research keywords from a single topic or business goal?
Yes. `find_keywords` starts from a seed topic and can be biased with a business goal such as demos, leads, or signups. You can also pass a site URL to check existing coverage.
How do I turn keyword ideas into a content plan?
Use `cluster_keywords` to group raw ideas into page clusters, priorities, and URL slugs. It is useful when you want an information architecture instead of a flat keyword list.
Can I score which keywords are worth targeting first?
Yes. `score_opportunities` ranks keywords by modeled demand, difficulty, and opportunity so you can separate quick wins from longer-term bets.
What does a deep keyword analysis include?
`analyze_keyword` gives you intent, SERP shape, modeled demand, difficulty, and a content brief with title angles for the keyword you are evaluating.
