Can I do keyword research for free?

Yes, keyword research can genuinely be done for free. Google's own autocomplete suggestions, the People Also Ask boxes, and the related searches at the bottom of a results page all reveal real phrasing people actually search for.

Google Search Console adds another completely free layer on top, showing exactly which queries your existing pages already get impressions for, often revealing near-miss opportunities you are not quite fully targeting yet.

The real tradeoff is precision. Free methods reveal what people search for reasonably well, but they rarely show exact volume or difficulty numbers, which paid tools tend to estimate more reliably from much larger data sets.

Research pulled from that kind of live search data is the starting point for every page automatic SEO software writes.
