Questions about Keyword Research.

Keyword Research returns monthly search volume, cost per click, paid competition and, if you ask, related keyword ideas for a keyword. You can type a plain-English request like "keywords for AI citation tracking" and Cite42 picks out the keyword first.
Yes. The batch option checks 2 to 50 keywords in one call for one country, returning volume, cost per click and competition for each. A batch costs $0.03-$0.09, depending on whether any keyword has search volume.
Keyword Research covers 13 countries: United States, United Kingdom, Canada, Australia, India, Germany, France, Spain, Italy, Netherlands, Brazil, Mexico and Japan. The language follows the country; the US, Canada and India also accept a second language. Any other country is refused before a lookup, so you are never charged for another market's numbers.
Long, specific phrases often have too few searches to be measured. Those lookups cost $0.03 instead of $0.09, and Keyword Research offers broader variants that do have volume.
Cite42 is not free, but there is no subscription: you pay per call from a prepaid balance that never expires. The $1 signup credit covers 11 batch lookups of up to 50 keywords each.
No. Keyword Research measures search demand. Keyword Rankings checks where your site ranks in Google's top 100 for each keyword, which page ranks, and whether the AI Overview cites you.
Those servers bring one SEO provider's data into your AI assistant. Cite42 puts keyword data next to AI visibility, citations, Google Trends, Reddit and YouTube in one MCP server, billed per call with no subscription. Choose a dedicated SEO suite when you need backlinks or site audits, which Cite42 does not offer.
It depends on the result: $0.03 for a keyword with no search data, $0.09 for one with data, and $0.12 when you ask for related ideas. Batches of up to 50 keywords cost $0.03-$0.09.
