AI Overviews is anartificial intelligence (AI) feature integrated intoGoogle Search that producesAI-generated summaries of search results. The feature has been criticized for its accuracy and for reducing traffic to content websites.
AI Overviews were first introduced as part of Google'sSearch Generative Experience (SGE), which was unveiled at theGoogle I/O conference in May 2023.[1] In May 2024 at Google I/O 2024, the feature was rebranded as AI Overviews and launched in the United States.[2] The introduction of AI Overviews was seen as a strategic move to compete with other generative AI advancements, includingOpenAI'sChatGPT.[2]
By August 2024, AI Overviews was rolled out to several other countries, including the United Kingdom, India, Japan, Brazil, Mexico, and Indonesia, with support for multiple languages.[3] In October 2024, Google expanded the feature globally, making it available in over 100 countries.[4]
In December 2024, Botify x Demandsphere released findings stating that when AI Overviews and Featured Snippets appear in the SERP together, they take up approximately 67.1% of the screen on desktop and 75.7% of the screen on mobile. Even if content is ranking in the #1 position, it may not be visible to consumers depending on the other visual elements on the results page.[5]
In March 2025, Google started testing an "AI Mode", where the search results page is AI-generated.[6] The company was also considering adding advertisements to the AI Mode, as they already exist in AI Overviews.[7]
As of May 2025, AI Overviews are now available in over 200 countries and territories, and more than 40 languages.
The AI Overviews feature useslarge language models to generate summaries based onweb content.[2] The overviews are designed to be concise, providing a snapshot of relevant information on the queried topic. Google allows users to adjust the complexity of the language in the summaries, offering both simplified and detailed options.[8][2]
The overviews also include links to sources.[3] According to a June 2025 study bySemrush, the most cited source isQuora, followed byReddit.[9]
Early iterations of the feature faced criticism for inaccuracies, including instances where erroneous ornonsensical content was generated.[10] Depending on what is searched for, the overview may also consist ofhallucinated content, such as when searching for idioms that do not exist.[11] In May 2024, Google temporarily restricted the AI tool after it provided nonsensical and harmful suggestions, such as telling users to eat rocks or apply glue on pizza.[12]
Concerns were also raised by content publishers, who feared a decline inweb traffic as users relied on the summaries instead of visiting source websites.[14]
Furthermore, there is apprehension about theethical implications of AI-driven content aggregation, including its impact onintellectual property rights and the visibility of smaller content providers.[14]
In response, Google has stated its commitment to improve content validation and refine thealgorithms used to filter unreliable information.[10] Google implemented measures to prioritize link placement within AI Overviews, aiming to balance user convenience with the needs ofcontent creators.[3] In January 2026, Google restricted AI Overviews on certain health-related searches following an investigation byThe Guardian.[15][16]
On February 24, 2025,Chegg suedAlphabet over the AI Overviews feature, claiming that it was leading to students preferring "low-quality, unverified AI summaries", thus violatingantitrust law.[17] Chegg also said it was considering either a sale or a take-private transaction.[17]
In September 2025,Penske Media Corporation, the publisher ofRolling Stone andThe Hollywood Reporter, sued Google, claiming that AI Overviews illegally regurgitate content from their websites and drive off potential site visitors by always appearing on top of the search results while leaving little incentive to see the linked sources.[18][19] The company stated that "the future of digital media and [...] its integrity [...] is threatened by Google's current actions", alleging that 20% of searches that link to Penske-owned websites show AI Overviews and that the figure is expected to rise. Googlespokesperson José Castañeda called the claims "meritless" and stated that "AI Overviews send traffic to a greater diversity of sites."[20][21][22]
