Zero-click search: why high rankings do not turn into AI citations
A TBWA Korea column writes that a brand can keep its search rankings and still be missing from answers given by ChatGPT, Perplexity and Google AI Overviews, because answer engines judge question fit, trust and brand association rather than rank.
