What's Changing on the Google Search Page?
The other day, I searched for an industry question on Google. Instead of the familiar blue links, I first saw a neatly compiled AI-generated answer. It summarized the question, offered different perspectives, and kept the sources for further reading.
In the past, users typed in a keyword and then clicked through web pages one by one. Now, AI Overviews or Google AI Mode can help users form an initial understanding first, before they decide whether to click through or ask follow-up questions. The blue links haven't disappeared; the change happens before the links.
Traditional search hasn't gone away; it's simply gained a new layer of understanding. Beyond optimizing rankings, businesses now need to consider whether their information can be included in the knowledge base used to generate AI answers.
Does AI Search Change Rankings, or the Way We Evaluate?
I started doing SEO at a Hong Kong digital marketing agency in 2005, and I've navigated the shifts from Yahoo to Google to today's generative search.
Each change looks like a new entry point: directories became search boxes, and keyword queries evolved into continuous conversations. But the deeper change is in how systems understand and evaluate information.
Changes in search entry points are, at their core, changes in how information is evaluated.
The challenge isn't just about where a page ranks, but whether a brand's perspective and evidence form a stable body of information.
How Have Three Generations of Search Moved Competition from Keywords to AI Trust?
The Yahoo Era: Getting Listed in the Right Directory
Early search relied heavily on human categorization and keyword matching. The first priority for businesses was "where to appear." Pages, keywords, and directory placement were the key assets.
The Google Era: Making Pages Worthy of Rankings
PageRank made link relationships a crucial signal for evaluating a web page's value. Businesses began long-term efforts in website content, technical structure, and external links, and SEO gradually evolved into a comprehensive discipline.
The AI Search Era: Making Brand Information Synthesizable
AI doesn't just return pages. It needs to understand the question, compare information, and organize an answer. Brands can't just leave behind scattered web pages; they need their product definitions, expert opinions, and third-party verifications to be consistent.
A head of marketing overseas once asked me: "Our Google rankings are good, so why doesn't ChatGPT mention us when it recommends solutions?" He then turned his laptop toward me, pointing at a competitor's brand in the answer.
I paused and said, "Ranking well and being understood by AI are two different things." He looked puzzled for a moment and asked, "So is SEO useless?"
Of course not. SEO makes information discoverable; GEO goes further to ensure information is understandable. The two are additive, not a replacement.
Why Isn't GEO Just Another Set of Ranking Tricks?
When businesses first encounter GEO, they often ask: Is publishing a few pieces of content enough? Will building more backlinks increase AI citations? Can optimizing a few pages solve the problem?
This concern is understandable. It's natural to use past search experience to make sense of new changes and to look for a direct action.
But an AI answer isn't a fixed results page. Rephrase the question, and the answer might change. Content, technical foundation, and external mentions still matter, but they shouldn't be reduced to a "publishing volume formula."
What AI search needs isn't just web pages, but brand knowledge that can be understood.
GEO deals with information relationships: how a company defines itself, what problems its products solve, which content provides evidence, and which third-party sources offer validation. It can't promise citations, but it can make brand information clearer and easier for machines to recognize.
What Exactly Constitutes a 'Search Asset' in the AI Era?
In the past, discussions about search assets focused on websites, rankings, and backlinks. Today, it includes at least five categories:
- Consistent public information: Do different channels use the same brand and business definitions?
- Specific product descriptions: Are features, use cases, and boundaries clear?
- Ongoing industry perspectives: Can the business explain the issues customers truly care about?
- Third-party validation: Are brand claims supported by independent sources?
- Clear website structure: Are page hierarchies and semantic relationships easy to understand?
Competition isn't just about having content; it's about whether that content forms a stable information system.
When my team and I proposed AIPO, we broke the work down into five rings: Platform to observe how platforms understand the brand; Content to plan content; Optimization to adjust website expression; Monitoring for continuous re-testing; and Analytics to analyze changes.
These five rings remind businesses to audit first, build second, and observe continuously. Search assets are a knowledge system that requires ongoing maintenance.
How Do the Focus Points of SEO and GEO Differ?
| Search Phase | Key Business Question | Core Assets |
|---|---|---|
| Yahoo Era | How to get listed in directories and be found | Pages and keywords |
| Google Era | How to achieve better rankings | Website quality and link ecosystem |
| AI Search Era | How to become a trusted source of answers | Brand knowledge system |
These three phases aren't strictly separate. Businesses still need to focus on pages, keywords, website quality, and their link ecosystem, while also adding observations on brand mentions, answer context, and citation sources.
SEO addresses whether web pages can be found, while GEO focuses on whether brands can be correctly understood by AI. Each can reveal gaps in the other.
How Should Businesses Adjust Their Search Strategy Next?
If you're a CMO, I suggest re-evaluating your search goals. Keep tracking rankings and organic traffic, but also document which questions your brand appears in, in what capacity, and which sources the answers are based on.
If you're a head of marketing, I suggest reviewing your website, product materials, and industry perspectives together. Start by resolving definitional conflicts, outdated materials, and key questions that remain unanswered.
If you're responsible for SEO, I suggest maintaining your technical, content, and link-building capabilities, while also adding testing with real user questions to observe how users continue their queries when comparing solutions or screening vendors.
Getting baseline data before deciding where to invest is a more reliable approach than adjusting based on intuition.
What New Stage Has the Search Industry Reached?
Looking back across the three generations of search, Yahoo taught businesses to understand entry points, Google taught them to understand rankings, and AI search is now demanding they understand trust. These aren't simple replacements; each adds new conditions for how information is evaluated and adopted.
SEO hasn't disappeared; it's entering a new phase of moving from vying for position to building trust.
The question businesses need to answer isn't just "Can users find me?" but also "Can AI accurately understand me?" Search assets will also evolve from ranking positions to brand knowledge that can be consistently verified.

Will Google AI Overviews affect business website traffic?
It changes the path users take to access information and click on pages, but the impact varies by industry and question type. Businesses should continuously monitor traffic, clicks, and AI appearances together.
What is the main difference between GEO and SEO?
SEO focuses on the discoverability and performance of web pages; GEO focuses more on whether brand information can be correctly understood by generative systems.
Do businesses need to discard their original SEO strategies?
No. Technology, content, experience, and external validation remain important. Businesses should add brand information management and re-testing on this foundation.
Why does AI cite certain brand content?
Systems organize answers based on the question and available sources, and results vary by platform and context. Stable and corroborated information is more easily recognized, but this doesn't guarantee citation.
How should a business start with GEO?
Start by checking your brand's presence, context, and sources against real business questions, then analyze content gaps, website structure, and information consistency.
If you're a CMO, start by understanding your brand's AI search performance; if you lead marketing or SEO, use the same set of real questions to establish a re-testing baseline. Get the data first, then make decisions.
