[DigitalToday reporter Hyunwoo Choo] Pluszero, a GEO data consulting firm, unveiled an integrated “VoC×GEO” strategy it said would help overcome a search marketing crisis in the AI era. Jung Sung-jin (정성진), CEO of Pluszero, appeared as the first speaker on June 10 at the marketing conference “The End of Experiments, the Beginning of Results” and presented key algorithms and execution strategies for generative AI search engine optimisation (GEO).

Jung said the spread of generative artificial intelligence (AI) such as ChatGPT and Gemini has ushered in a full-fledged “zero-click era,” in which users finish searches using only AI answers without clicking links in search results. Portal search link click-through rates have recently plunged 60 percent, he said.

He also stressed that “it is difficult to expect meaningful results with only existing search engine optimisation (SEO) methods.” He said the shift should be to an integrated strategy that combines SEO with GEO and answer engine optimisation (AEO) so AI search engines cite brands first.

Pluszero laid out a four-step GEO build strategy. It starts with identifying “real questions” in voice-of-customer (VoC) data that contribute to actual purchase conversion. It then designs structured answers that are easy for AI to cite, optimises AI readability through script engineering, and meets a volume threshold by distributing at least 30 to 50 pages of high-quality content. Pluszero also introduced its solutions “Gewriter” and “VoC Intelligence” that it said can internalise the process.

“Accurately getting our brand cited in AI answers is now an essential survival strategy for marketing,” Jung said.
