Questions about keyword research

Where does the keyword data come from?

From DataForSEO. When you press Analyze, Rext AI asks it for the search results for your keyword in the country you picked, with the monthly volume, the difficulty from 0 to 100, the backlinks and referring domains, and the domains that rank. The questions people also ask and the related searches come from the same results page.

Does researching a keyword cost credits?

Yes: analyzing a keyword costs one credit, and confirming it as the article's keyword costs one more. Picking a different keyword at that step runs the analysis again and costs another credit. Starting an article from a keyword under Keywords within a week reuses its research, so the search isn't charged again; after a week, the search results are read again for one credit.

Can I change the search intent?

Yes. Rext AI preselects the intent the search results point to, and you can choose informational, commercial, transactional or navigational instead. Your choice overrides the results, and the content types offered at the next step are the ones that fit it, such as a blog post or a how-to guide for an informational keyword.
