Google Search is changing faster than many businesses expected.
AI Overviews are already appearing in search results across countless industries, while AI Mode is pushing Google further towards a conversational search experience. For businesses that rely on organic traffic, understanding the difference between the two is now essential.
A recent discussion featuring Google’s Nikola Todorovic, Director of Software Engineering at Google Search, gave the SEO industry a clearer look at how these systems actually work behind the scenes.
The key takeaway is simple: AI Overviews and AI Mode are connected to Google Search, but they are not the same product.
That distinction matters for SEO.
What are Google AI overviews?
AI Overviews are the AI-generated summaries that appear directly within standard Google search results.
Google uses traditional search systems alongside AI to generate a quick answer for the user. The system pulls information from multiple sources, processes additional “fan-out” queries behind the scenes, and then creates a summary above the organic listings.
In simple terms, AI Overviews still sit on top of traditional Google Search.
The normal ranking systems still matter.
Websites still compete for visibility through relevance, authority, technical SEO, and content quality. The difference is that Google now uses AI to summarise information before users reach the standard search results.
For publishers and businesses, this creates a major shift in click behaviour. Users can often get a quick answer without clicking through to a website.
What is Google AI mode?
AI Mode is a different experience entirely.
Instead of adding an AI summary to normal search results, AI Mode creates a more conversational environment where users can ask follow-up questions, refine searches, and explore topics in depth.
Google has explained that AI Mode uses its own infrastructure while still relying on Search systems underneath.
That means AI Mode is not simply “Google Search with extra text”.
It is closer to an AI assistant powered by Google’s search data.
Users can stay inside one conversation for much longer, which changes how websites earn visibility and traffic.
Why Google built these systems separately
According to Google, AI systems are difficult to debug and control when everything runs through one large model.
Earlier AI systems such as SafeSearch were isolated because engineers could more easily identify problems and improve performance. The same principle now applies to newer AI technologies powering Search.
AI Overviews work as an additional layer on top of traditional ranking systems.
AI Mode operates more independently because it handles longer conversations and more advanced reasoning.
This explains why businesses may see different visibility patterns between AI Overviews and AI Mode in the future.
What this means for SEO
Many businesses are asking the same question:
“Does traditional SEO still matter?”
The answer is yes, but SEO is evolving.
Google has repeatedly stated that helpful, valuable content remains central to visibility across AI-driven search experiences.
However, AI search changes how content is discovered and displayed.
SEO is moving beyond rankings
Ranking first is no longer the only goal.
Businesses now need content that can:
Answer questions clearly
Demonstrate expertise
Provide trustworthy information
Offer original insight
Support conversational search journeys
AI systems are designed to extract and summarise information quickly. Thin content, repetitive articles, and heavily optimised pages with little real value are becoming easier for Google to ignore.
Authority matters more than ever
AI-generated answers rely heavily on trusted sources.
Strong brand signals, expert-led content, high-quality backlinks, and topical authority all become more important when Google decides which sources to reference inside AI-generated experiences.
Businesses that publish genuine expertise will have a stronger chance of appearing within AI summaries and citations.
Search intent is becoming more complex
Traditional SEO often focused on individual keywords.
AI Mode changes this because users can ask layered questions within one conversation.
For example, instead of searching:
“best CRM software”
Users may ask:
“What is the best CRM for a growing estate agency with under 20 staff that needs email automation and low onboarding costs?”
That creates a much deeper level of search intent.
Businesses need content that answers real-world problems rather than targeting isolated keywords.
Will AI mode reduce website traffic?
In some industries, yes.
AI Overviews have already contributed to more zero-click searches because users can get answers directly from Google without visiting a website.
AI Mode could push this even further for informational searches.
However, this does not mean SEO is disappearing.
Traffic quality may become more important than traffic volume.
Users who do click through from AI-generated experiences are often further into the research process and may have stronger intent.
For businesses, the focus should shift towards:
Building brand visibility
Becoming a trusted source
Creating genuinely useful content
Improving conversion quality
Strengthening topical authority
What businesses should do next
Businesses that adapt early will be in a stronger position over the next few years.
The priority should not be chasing AI shortcuts or mass-producing content with automation.
Instead, focus on:
Create content written by experts
AI-generated summaries favour trustworthy information. Expertise matters more than ever.
Build topical authority
Cover subjects thoroughly instead of publishing disconnected articles targeting random keywords.
Improve content quality
Original research, real experience, case studies, and practical insight help content stand out.
Optimise for user value
Google continues to repeat one consistent message: content should help users first.
Strengthen brand recognition
Brands users recognise are more likely to earn trust, clicks, and citations across AI-driven search experiences.
The future of search is already here
Google AI Overviews and AI Mode are not experiments sitting on the sidelines anymore.
They are shaping how users search, how information is discovered, and how businesses earn visibility online.
Traditional SEO principles still matter, but the way Google delivers information is changing rapidly.
The businesses that succeed will be the ones that focus less on manipulating rankings and more on becoming genuinely useful sources of information.
