How AI Is Changing Search Results and Powering Google’s AI Mode

5 Minute Read

This post describes how AI is influencing the structure and way data is retrieved, how search results are displayed, and how it affects people’s internet search experiences. We also explain how this relates to Google's AI Mode feature, which we examine in closer detail.

Understanding AIO, AI Search & AI Overviews

AIO (Artificial Intelligence Optimization) is the process of building your website content to be read or crawled by artificial intelligence—namely AI-driven search. Information within your site being displayed as part of a Google AI Overview is a familiar example of this mechanism. This process is fundamentally similar to SEO, since both emphasize improving website domain authority and creating content that is trustworthy and reliable; i.e., a trusted “go-to” source for a specific subject matter or industry.

AI Search refers to the evolving algorithmic process that combines natural language processing (NLP, which helped initiate the evolution of search) and large language models (LLMs) like Gemini, Grok, ChatGPT, etc. (which is where search is now heading) to understand a person’s search intent. Then, it aims to serve up precise content, specific facts, and insightful information that satisfies the user’s needs by answering a question, solving a problem, or finding a specific product or service. AI search behaves very much like enterprise statistical data mining software because of its magnitude of information retrieval. This big data approach to database querying, once a private endeavor, has now been made public through a free or subscription-based consumer model in AI search.

AI Overviews represent the summarized search results that Google and other engines display above top-ranking websites and advertisements. This AI summary is sourced and pulled from a variety of online sources, including discussion boards such as Reddit and public websites that publish content related to a user’s specific search parameters.

Think of AI overviews as a time-saving mechanism. Traditionally, searchers often visited multiple websites, read through various webpages, and synthesized all of that information to develop a takeaway. Now, these overviews help to streamline the information gathering process. While not exhaustive, AI overviews can serve as a convenience feature for conducting quick, at-a-glance, high-level online research.

How Google’s AI Mode in Search May Impact the Future of SEO

On May 19th, Google unveiled their biggest change ever to what they do best, internet search. With AI models like ChatGPT, Claude, Grok, and Perplexity competing with each other, and with Google, for their own shares of the search market, the search engine announced a revolutionary new way for users to search for and discover information. Google is calling this process “AI Mode Search.”

AI Mode Search is a unique hybrid model that blends classic search with artificial intelligence. Google users can still make basic queries just like they did before, such as searching for “Auto repair near me," which will yield a list of local car repair shops. However, the artificial intelligence component seamlessly ingests long-form detailed questions and conversational inputs. For example, asking Google "How can I prevent my rose bushes from drying out in the Summer?” will yield an AI summary of advice pulled from a variety of online sources, with the ability for users to ask follow-up questions. Beneath the “Ask Anything” box is a list of YouTube videos for visual guidance, and below that a list of familiar blue links to websites about gardening. From this same results page, at the very top, you can switch to AI Mode which is fundamentally a pure-play AI interface (reminiscent of Gemini) where users can engage Google’s artificial intelligence without any traditional search results. These UI functions have been available for some time. So, what is the really big news from Google?

This new evolution of global AI Mode Search didn’t arrive without a cosmetic change. After 25 years of keeping its UI and iconic search bar relatively unchanged, Google rolled out a fresh new interface along with a search bar with built-in AI functionality. Behind this new search bar, Gemini 3.5 Flash is ready to ingest queries, run a deep internet search, process the results through artificial intelligence reasoning, and produce a detailed summary in a natural language format.

On the desktop version of Google, the left side of its search bar now features a plus sign (+) that when clicked, will provide a drop-down menu. This menu begins with suggested search prompts that are informed by recently viewed and open tabs in Chrome. The next option under the (+) provides the ability to upload images or PDF files as supporting documentation for its AI processing. The third option is a section called “Tools,” which has the capability to either create an AI image or use Canvas, each one with example prompts to get you started. Google Canvas is a new service that generates a visual itinerary based on restaurant or travel prompts, for example, and includes agentic booking capabilities.

On this same desktop version of Google, next to the voice-to-text search function, the right side of the search bar features Google Lens, which initiates an internet search by uploading a photo or pasting an image URL. Next to this feature is a button, represented by an icon of a magnifying glass, called “AI Mode.” Clicking on AI Mode drops down the search bar for users to enter a more detailed question like “How can I make tiramisu?” which then takes you to a new AI-powered environment with a list of ingredients and steps to prepare the dessert, with web sourcing displayed on the right, like old-school ad banners.

For those of us who have been using Gemini from the start, this integration will feel natural, as it brings together the power and usability of the tool, combining standard internet search with some minor adaptations to toggle between standard browsing and AI Mode Search within the same UI.

One of the coolest features is you now have the ability to set up Google AI Search Agents to keep you informed of specific topics. They will continuously scour the web on your behalf, based on the parameters they've been given, and send push notifications on any updates that fit the original prompts. These AI Search Agents, in a sense, will work like Google News Alerts, whereby breaking information is immediately delivered to you.

So, what do all these changes from Google mean for internet search and SEO? As we’ve seen in the previous example of “Auto repair near me,” local business searches and listings are largely unaffected. Ultimately, what this means is that keywords are still very much in play for standard querying, although the real estate at the top of page one will appear differently based on the keywords (or long-form prompts) the search bar receives.

For AI search and summaries, there is a nuance arising from longer, more thoughtful search intent, with dependencies stemming from website content that is structured to be included within AI results. Since NOBLE SEO has been studying Google’s algorithm, using its tools, and closely watching its AI evolution in real time, we have previously published posts in our Knowledge Base section, covering topics to help you prepare for this migration. Refer to our Knowledge Base entry “GEO Explained: How to Prepare Your Website for AI Search” to help guide your website planning and design for AI readiness.

In short: subject matter authority, website trust, and useful structured content coupled with your website’s technical performance and agility still matter. In fact, they are now more important than ever for webpage indexing and extraction into AI summaries and organic search results.
