Keyword Generator — FAQ

Are the volume and difficulty estimates accurate?

They're model estimates (Low/Medium/High). For precise numbers, verify winners in Google Keyword Planner or a paid tool.

What is search intent?

Why someone searches: informational (learn), commercial (compare), transactional (buy) or navigational. The tool groups keywords by intent so you match content to the searcher.

How many keywords should I target per page?

One primary keyword plus 3-5 related long-tail variants. The clusters help you pick a primary and its supporting terms.

Can I generate keywords in other languages?

Yes — enter your topic in any language and the clusters adapt to that language's search behavior.
