What Is AI Overview on Google?

Google AI Overviews is a new feature that provides users with AI-generated summaries and relevant links at the top of select search results pages. When a user enters a query, Google’s advanced algorithms analyze the search terms and, if deemed appropriate, generate a concise overview that aims to directly answer the question or provide key information on the topic.

Under the hood, Google AI overview is powered by the Gemini language model, a sophisticated Google AI system. This LLM has been customized specifically for Google AI Search, integrating with the platform’s existing search systems and vast index of web content.

By leveraging techniques like retrieval augmented generation (RAG), the Gemini model can effectively draw from relevant online sources to inform its outputs.


Here’s a simplified breakdown of how Google Search AI Overviews work:

  1. A user enters a search query, such as: “What are the benefits of meditation?”
  2. Google’s search systems process the query and determine if an AI Overview would be helpful.
  3. If selected, the Gemini model analyzes the query and retrieves relevant information from web sources.
  4. The model then generates a succinct summary, aiming to provide a direct answer and key points related to the query.
  5. The AI-generated summary, along with links to relevant web pages, is displayed at the top of the search results as a Google AI Overview.

While the exact details of Google’s Gemini model remain proprietary, it likely employs techniques like RAG to enhance its outputs. RAG allows language models to reference external sources rather than relying solely on training data, enabling more accurate and up-to-date information in the resulting AI Overviews.

As Google generative AI continues to advance and evolve, AI Overviews are poised to become an increasingly prominent feature of the new Google Search experience.

However, this transformative technology is not without its share of challenges and limitations.

How AI Overviews Can Go Wrong

While Google AI Overview represents a significant leap forward in search technology, the feature has also faced criticism for producing notably inaccurate, inappropriate, and even nonsensical outputs. Despite the benefits of Google Search AI Overviews, these failures highlight the current limitations and challenges of Google generative AI models.

One of the most infamous examples of a Google AI Overview gone wrong occurred when a user searched for “How many rocks should I eat?” Shockingly, the AI-generated summary responded by suggesting that eating one small rock per day was acceptable.

In another bizarre instance, an AI Overview for the query “How to keep cheese from sliding off pizza” recommended using glue as a solution.

These glaring errors underscore the potential for Google Search AI Overviews to provide not just misleading but potentially harmful information. Other examples of search generative experience missing the mark include:

  • Suggesting that former U.S. President Andrew Johnson earned degrees in the late 20th century despite dying in 1875
  • Misinterpreting a satirical article and presenting it as factual information
  • Generating nonsensical or irrelevant summaries for ambiguous or poorly phrased queries

So, what causes Google generative AI to produce such blatantly inaccurate outputs? There are several factors at play:

Outdated or Limited Information

While Google AI systems like the Gemini model can draw from vast amounts of web data, they may sometimes rely on outdated, incomplete, or unreliable sources. This can lead to AI Overviews presenting information that is no longer accurate or relevant.

Misinterpreted Context

Language models can struggle to grasp the nuances of human communication, such as sarcasm, satire, or ambiguity.

When a Google AI Overview fails to properly interpret the context of a query or source material, it may generate outputs that are wildly off the mark.

Data Biases & Gaps

Google generative AI models are only as unbiased as the data they are trained on. If certain perspectives, facts, or areas of knowledge are underrepresented or absent from the training data, the resulting AI Overviews may reflect those biases and limitations.


In some cases, language models can generate plausible-sounding but entirely fabricated information, a phenomenon known as “hallucination.” This can lead to Google Search AI Overviews presenting convincing yet completely false statements as fact.

As Google continues to refine and improve its Google AI Overview feature, addressing these challenges will be crucial. From fine-tuning the Gemini model’s ability to interpret context and intent to ensuring the quality and diversity of its training data, ongoing advancements will be key to mitigating the risk of inaccurate or inappropriate outputs.

However, even with these improvements, the rise of AI Overviews poses important questions about the broader implications for online search and the businesses that rely on it.

The Pros & Cons of AI Overviews in 2024

Ultimately, the rise of AI Overviews represents a significant shift in how we navigate online information. This shift could have far-reaching implications for the businesses and ecosystems that have been built around traditional search models.

Impact on Businesses & Web Publishers

The introduction of Google AI Overviews has raised concerns among businesses and web publishers who rely heavily on search engine traffic for their livelihood. As Google AI Overviews become more prevalent and sophisticated, there is a growing fear that these AI-generated summaries could significantly decrease click-through rates (CTR) from Google’s search results to external websites.

The primary concern is that if users can quickly find the information they need directly within the Overview, they may be less likely to click through to the original source. This could lead to a substantial reduction in organic search traffic for websites, particularly those that rely on informational content to attract visitors.

Reduced CTR could have a cascading effect on these websites’ revenue streams, as fewer visitors typically translate to lower ad impressions, clicks, and conversions. For businesses that heavily depend on search referrals to generate leads, sales, or ad revenue, a significant drop in traffic from the new Google Search could be devastating.

Moreover, if Google AI Overview becomes the default way users consume information online, it could lead to a fundamental shift in how websites create and optimize content. As Google’s models become better at extracting and summarizing information, web publishers may feel pressured to adapt their content strategies to prioritize appearing in AI Overviews rather than attracting organic clicks.

Businesses and web publishers will need to closely monitor the impact of Google Search AI Overviews on their traffic and revenue. They may need to adapt their content strategies, SEO tactics, and monetization models to remain competitive in search, increasingly dominated by Google generative AI.

Potential Strategies for Businesses to Mitigate the Impact of AI Overviews

  1. Focusing on creating unique, high-quality content that goes beyond surface-level information and offers valuable insights, opinions, or experiences.
  2. Diversifying traffic sources and reducing reliance on organic search by investing in other channels like email marketing, social media, or paid advertising.
  3. Optimizing content for featured snippets and other SERP features to increase visibility and CTR, even if a Google AI Overview is present.
  4. Exploring alternative monetization models, such as sponsored content, affiliate marketing, or subscription-based services, to reduce dependence on ad revenue.

Google is actively working on improving its features to address concerns around accuracy, reliability, and the impact on web publishers. However, the full implications of this technology for businesses and the search ecosystem as a whole are yet to be seen.

Google’s Plans & Improvements

One notable development in recent months has been the reduction in the frequency of AI Overviews appearing in search results.

According to data analyzed by BrightEdge, the prevalence of Google Search AI Overviews has decreased from a peak of around 40-50% of search results to approximately 15% as of June 2024. This suggests that Google is becoming more selective in determining when and where to display AI-generated summaries, possibly in response to user feedback and quality concerns.

To improve the accuracy and relevance of AI searches, Google has been fine-tuning its query interpretation and context understanding capabilities. By better grasping the intent behind users’ searches, the Gemini model can generate more precise and helpful summaries.

Additionally, Google has implemented filters to identify and exclude content from sources like satire websites or humorous forums, which have been responsible for some of the more bizarre and inaccurate AI Overviews.

Google has also been refining its feedback mechanisms to gather input from users and web publishers on the quality and utility of the results. This includes options for users to rate the helpfulness of AI Overviews and report inappropriate or inaccurate content.

Looking ahead, Google’s long-term vision for generative AI in search extends beyond simply providing summary overviews. The company has hinted at plans to integrate AI-powered features like multi-step query resolution, personalized recommendations, and interactive dialogue interfaces to create a more intuitive and efficient search experience.

The Bottom Line

Google AI Overviews represent a significant milestone in the evolution of search. They offer users quick access to relevant information while also raising important questions about the future of online content discovery. As Google generative AI continues to advance, striking the right balance between convenience and accuracy, as well as between user experience and publisher interests, will be critical.

While Google AI Overview is still in its early stages, with challenges related to reliability and context understanding, Google’s ongoing efforts to refine and improve the technology suggest a future where AI and human-curated content can coexist and enhance each other.

The path forward may not be without obstacles, but the potential benefits of Google Search AI Overviews – from more efficient knowledge acquisition to new opportunities for content creators – make them a transformative force in AI-powered search experiences.
