What are AI Overviews and how do they work?

With AI Overviews, search is becoming more AI-driven. Google now combines tra­di­tion­al search results with gen­er­at­ive AI answers, giving users more detailed in­form­a­tion right away.

What are AI Overviews?

Google AI Overviews (pre­vi­ously known as Google SGE) bring gen­er­at­ive AI directly into Google’s search results. Instead of just showing links and snippets, AI Overviews generate short summaries that pull together in­form­a­tion from multiple sources. To do this, they rely on large language models, capable of un­der­stand­ing natural language and gen­er­at­ing text on their own. This gives users quick answers to their questions without needing to visit multiple websites.

AI Overviews respond to a user’s search query and, together with Google AI Mode, offer in­ter­act­ive features such as exploring topics in more detail or tailoring results to user pref­er­ences. The goal is to better match search intent while also improving the overall user ex­per­i­ence. At the same time, AI Overviews change how companies need to approach content, since the AI decides what to summarise and highlight.

How do Google AI Overviews work?

Google AI Overviews rely on advanced AI models trained on large datasets to un­der­stand search queries. When you enter a question, the AI analyses it, iden­ti­fies related topics, and pulls together relevant in­form­a­tion from across the web. It then generates a response that sum­mar­ises the key points and includes links to sources. It may also suggest next steps or show related questions. Unlike tra­di­tion­al search, the AI doesn’t rely only on keywords. It focuses on meaning, relevance, and trust­wor­thi­ness, and displays the answer above the standard organic results.

AI Overviews can also show different per­spect­ives on a topic and let users refine their results. Thanks to LLMs, even complex questions can be answered in natural, easy-to-read language. Google may also use signals such as user pref­er­ences to per­son­al­ise responses. The AI improves over time based on how people use it, although Google doesn’t share the exact details of how it’s trained. All in all, search now blends tra­di­tion­al results with AI-generated answers.

How do Google AI Overviews affect SEO?

AI Overviews are changing how search works, and that has a direct impact on SEO:

• AI answers reduce clicks: When an AI Overview appears, fewer people click on tra­di­tion­al search results, es­pe­cially for in­form­a­tion­al searches.
• Structure and clarity matter more: Content that’s clear, well-struc­tured, and trust­worthy is more likely to be picked up and shown in AI Overviews, even if users don’t click through.
• Content needs to answer real questions: AI Overviews mainly show up for in­form­a­tion­al searches, so content should provide clear answers to user questions, es­pe­cially long-tail queries.
• Search results are getting more complex: AI elements add another layer to the results page. Tra­di­tion­al rankings still matter, but the overall layout is more dynamic.
• Not every industry is affected the same way: Purely in­form­a­tion­al content, for example, is more likely to be affected than trans­ac­tion­al or strongly brand-driven searches.

Even with these changes, the basics of on-page SEO still matter. Clear structure, mean­ing­ful headings and well-organised content help Google un­der­stand your pages and use them as sources. It’s also worth looking at GAIO (Gen­er­at­ive AI Op­tim­isa­tion) and GEO (Gen­er­at­ive Ex­per­i­ence Op­tim­isa­tion) if you want to prepare your content for AI-driven results.

What are the ad­vant­ages and dis­ad­vant­ages of AI Overviews?

Google AI Overviews bring both benefits and chal­lenges for users and busi­nesses.

Ad­vant­ages

AI Overviews make it easier to get quick, easy-to-un­der­stand answers even for more complex questions. Instead of visiting multiple websites, users often get what they need right on the results page. This makes the overall search ex­per­i­ence faster and more efficient. For busi­nesses, this also creates new op­por­tun­it­ies. Content that’s well struc­tured and clearly written has a better chance of being featured in AI-generated answers.

AI Overviews also save time by showing the most important in­form­a­tion upfront. In some cases, they combine different per­spect­ives and sources into a single answer, which can help users make decisions more easily.

Dis­ad­vant­ages

At the same time, Google AI Overviews can reduce website traffic. If users already find their answer within the search results, they’re less likely to click through to a page. There’s also a risk of in­ac­cur­ate or mis­lead­ing in­form­a­tion if the AI mis­in­ter­prets or over­sim­pli­fies sources.

For busi­nesses, this means more work. Content needs to be optimised not just for search engines, but also for how AI systems interpret and present it. Vis­ib­il­ity depends heavily on how Google’s AI selects content, and companies have limited control over how their content appears in AI-generated answers.

How can you optimise for Google AI Overviews?

To benefit from AI Overviews, companies need to adjust their content strategy. Content should be clear, well struc­tured, and easy for both users and AI to un­der­stand. It’s also important to keep track of how your content performs. Here are some best practices:

• Structure your content for AI: Your content should be clear and easy to follow. Use short headings and para­graphs, along with lists and summaries, to break up the text. Aim for precise wording so the AI un­der­stands what your content is about. FAQ sections and step-by-step guides can also increase the chances of being picked up in AI-generated answers.
• Add mul­ti­me­dia and sup­port­ing content: AI Overviews in­creas­ingly include videos, images and struc­tured data. Using mul­ti­me­dia content can strengthen your vis­ib­il­ity in search results, es­pe­cially if you include YouTube videos or visual tutorials.
• Use reliable sources and ref­er­ences: AI tends to favour content that is supported by reliable sources. Linking to reputable websites and using studies or official stat­ist­ics helps build cred­ib­il­ity and improves your chances of being featured.
• Focus on user intent: Look at what users are actually asking and how those questions are answered in AI results. Your content should directly answer those questions, rather than just targeting keywords.
• Track per­form­ance over time: Monitor which of your pages appear in AI Overviews and how users interact with them. Use these insights to regularly adjust and improve your strategy.
• Keep your messaging con­sist­ent: Make sure your content is con­sist­ent and re­cog­nis­able. This helps the AI associate your brand with the right topics and include it in its answers.
• Optimise for different types of questions: AI Overviews often present multiple per­spect­ives on a topic. Your content should cover broader questions while still providing clear, detailed answers.
• Don’t neglect technical SEO: Even with AI-generated answers, page speed, struc­tured data, and mobile op­tim­isa­tion still matter for making your content dis­cov­er­able.
