Google AI Overviews: what they are, how they work and how to appear in them

Google is rolling AI Overviews out across more markets and more query types. How often they appear depends on the country, the language, the device and the intent, so a single global percentage should never be used to forecast traffic for a specific domain.

What are Google AI Overviews?

Google AI Overviews, previously Search Generative Experience, is a Google feature that generates a direct written answer to a user's query and displays it at the very top of the results page, above every organic link and advertisement. The answer is produced by an AI model built on Gemini, drawing on content from pages Google indexes.

An AI Overview does not appear for every query. Google triggers them mainly on informational, how-to and comparison questions. Transactional queries ("buy Nike trainers") and navigational ones ("facebook.com") still show conventional results. But estimates suggest AI Overviews appear on around half of all queries - an enormous share of traffic.

How AI Overviews affect organic traffic

This is the question that keeps anyone managing SEO traffic awake. The data is ambiguous and depends heavily on the category. In some categories appearing in an AI Overview raises CTR, because the source link is more prominent than a normal organic result. In others the AI Overview answers the question without a click, which reduces traffic to sites.

For B2B companies the consequences are usually less dramatic than for publishers and e-commerce. B2B decision-makers click through to sources to verify information and get to know a company before deciding to make contact. But sites not cited in AI Overviews for key category queries lose some of that traffic to competitors who are.

How Google selects sources for AI Overviews

An AI Overview is not the output of a separate algorithm - Google uses its existing ranking as the base. A page has to be in the top ten for a given query to be considered as an AI Overview source at all. Conventional SEO therefore remains a necessary condition.

But being in the top ten does not guarantee citation. Google selects from those pages the ones whose content is most citable - specific, directly answering the question and well structured. A page ranking eighth with an excellently written paragraph that answers the query head-on can be cited more often than a page ranking second with generic content.

Which query types generate AI Overviews

What to do to appear in Google AI Overviews

1. 1Get the SEO fundamentals right - without a top-ten position for your target queries there is no AI Overview. That is the entry condition and it cannot be bypassed. If you do not rank, start with SEO.
2. 2Optimise content for citation - write paragraphs that can be lifted without context and stand as a self-contained answer. The first sentence of a section should carry the main proposition. The optimal cited block is 134 to 167 words.
3. 3Use headings as questions - question-form headings map directly onto user queries. "How do I choose ERP software?" as an H2 is a direct answer to the query.
4. 4Add comparison tables and lists - Google AI Overviews readily cite comparisons, step lists and tables. These formats answer "what are the..." and "how do I, step by step" questions well.
5. 5Show dates and an author - content with a visible update date and a named author reads as more current and more credible.

AI Overviews and AI Visibility - what is the difference?

AI Overviews are exclusively a Google feature. AI Visibility, or GEO, is the broader category covering visibility across every AI system: ChatGPT, Perplexity, Gemini, Claude and others. Optimising for AI Overviews is a subset of a wider AI Visibility strategy.

The key practical difference: AI Overviews require good conventional SEO as their foundation. ChatGPT and Perplexity can ignore your Google position entirely - what counts for them is whether your brand is discussed online in the right context. A complete AI Visibility strategy has to address both paths.

How to check whether your company appears in AI Overviews

Go to Google and enter the queries you think your buyers ask. If an AI Overview appears, check whether your page is among the cited sources - they show as cards to the side or as links within the text. Test at least ten different queries from your category. Note who is cited instead of you; that is your competition in AI.

How to monitor visibility in Google AI Overviews

Monitoring AI Overviews is harder than tracking conventional SEO positions, because Google provides no dedicated data in Search Console. Several methods do allow systematic tracking, though. Below is the short version - the full treatment, including a Looker Studio dashboard, is in a separate guide: how to track visibility in Google AI Overviews.

1. 1Google Search Console - check the CTR metric for key phrases. A sudden CTR drop while impressions stay stable or rise can indicate that an AI Overview has taken the traffic. It is an indirect but important signal.
2. 2Manual checking - build a list of 20 to 30 key queries for your category and check weekly which of them trigger an AI Overview and whether your page is cited. Record the results in a spreadsheet.
3. 3ZipTie.dev - a specialist tool for monitoring Google AI Overviews. It tracks automatically whether your page is cited for selected key phrases.
4. 4Semrush AI Visibility Tracker - a Semrush module showing visibility in AI Overviews for tracked keywords.
5. 5Nightwatch - an SEO tool with AI Overviews tracking, integrating conventional position monitoring with AI visibility in one dashboard.

AI Overviews and Google AI Mode - what is the difference?

Google launched AI Mode, a separate tab in the search engine offering a fully conversational AI experience. Unlike AI Overviews, which appear above the organic results, AI Mode is a separate interface with no conventional organic links. That means the only route to visibility in AI Mode is being cited by the AI - there are no links a user could click independently of the answer.
