Abstract: The Digital Marketing Revolution from SEO to GEO

With the explosive growth of Artificial Intelligence (AI) and Large Language Models (LLMs), the global digital marketing ecosystem is at an unprecedented turning point. Traditional Search Engine Optimization (SEO), the core paradigm that has dominated internet information distribution for nearly two decades, is facing fundamental challenges and reconstruction. Taking its place is Generative Engine Optimization (GEO), a new visibility logic based on probabilistic models, knowledge graphs, and semantic reasoning.

This article provides a detailed review and extended analysis based on the insights shared by Riven Gao, Head of DTC Brand Technology at EasyClick (Yidian Tianxia), during the GEO Roundtable Conference and related strategic documents. The report adopts a structure of "In-depth Background Analysis + Roundtable Recap + Core Theory Extension." It not only recreates the brilliant Q&A session of the roundtable but also builds a complete GEO theoretical framework and practical guide. Specifically, it breaks down the "New KPI Indicator System" proposed during the meeting, analyzing the evaluation chain from "visibility" to "business value."

This article aims to provide a detailed action blueprint for global brands, digital marketing practitioners, and corporate decision-makers. By understanding and applying GEO strategies, they can seize the cognitive high ground in the upcoming era of "Agentic Commerce" and achieve a strategic leap from "being searched" to "being recommended."

Chapter 1: Conference Background & Macro Industry Context

1.1 Digital Marketing's "Oppenheimer Moment"

We are living in an era that is being redefined. The release of ChatGPT by OpenAI, the launch of AI Overviews (formerly SGE) by Google, and the rise of answer engines like Perplexity are not just tool iterations; they represent the collapse and reconstruction of the underlying logic of information retrieval.

At the EasyClick GEO Roundtable, industry experts gathered to discuss the profound impact of this change on global brands. The conference background was built on a core consensus: The search box is no longer an entrance to a list of web pages, but an interface for instant knowledge synthesis. Users are no longer satisfied with filtering through "ten blue links" themselves; they expect AI to directly provide the "best answer."

For brands, this triggers deep anxiety:

• If users no longer click on links, where will the traffic to the brand's official website go?
• If AI controls the power of recommendation, how can brands ensure they are "seen" and "preferred" by AI?
