AI Overviews
AI Overviews are AI-generated summaries that Google shows on some search results pages, usually above the classic results. An overview answers the query in a few sentences or a list and links to the web pages it drew on. Google introduced the feature as Search Generative Experience in 2023 and renamed it AI Overviews in 2024.

Why it matters.
Google announced generative AI in Search as an experiment in May 2023[1] and began bringing AI Overviews to everyone in the United States in May 2024[2]. An overview takes the top of the page, so a query can be answered before the first classic result is seen. For informational queries, such as how to measure for a bed frame or what a good churn rate is, it may satisfy the searcher without a click.
Overviews do not appear on every query. Google shows one when its systems judge that it adds value beyond the classic results, and may run several related searches across subtopics, a technique it calls query fan-out, to build it[3]. The pages linked inside it are the ones that keep their visibility.
A page does not need to rank first to be linked in an overview, and ranking first does not guarantee a link. To be shown as a supporting link, a page has to be indexed and eligible to be shown with a snippet; Google lists no other technical requirement[3].
For a business, the question is not whether overviews are good or bad but which of its queries they appear on. A query that brings buyers and now shows an overview needs a passage that the overview can link; a query where the overview answers everything may no longer be worth a new page.
How it is measured.
Per tracked query: does an overview appear, is your page among its linked sources, and which competitors are. Search Console reports clicks, impressions, click-through rate and position by query and page[4]. Those figures say how a query performed, not what the results page looked like, so the page itself has to be observed to know when an overview appeared and whom it linked.
Read the two together. A query whose position holds while its click-through rate falls is the pattern to check first: an overview above the results is one common cause, and a changed title or the season are others.
Read the robots rules too. Google-Extended, the token Google points to for limiting AI training and grounding in some of its other systems[3], is blocked by name on 411 of the 6,294 top sites whose robots.txt could be read, 6.5%[5]. Each token governs a named product, so read its documentation before writing a rule.
Measured by
- Overview shown
- Linked as a source
- Competitors linked
A worked example.
Sample data: an invented site, to show the method.
A SaaS company tracks “what is a good churn rate for SaaS”. Google shows an overview with three linked sources, and the company’s benchmark guide is the second. In Search Console the query’s position held while its click-through rate changed: the pattern an overview produces.
The overview’s wording says that a good rate depends on the customer, the point the guide makes in its first paragraph, which is why that passage is the one linked.
What to do, step by step.
List the queries of your topic where an overview appears, and record on each tracked day whether it appears and which pages it links.
For each query where a competitor is linked and you are not, compare the two passages: which answers the query in its first sentences, and which states the facts more clearly?
Rewrite the passage of your page that should answer the query, answer first, and keep the page indexable and eligible for a snippet.
Watch click-through rate by query in Search Console beside the overview record, so a change in clicks is read against what the results page showed.
Judge the change over several weeks of observations, not one search: overviews vary with the wording of the query and over time.
Mistakes to avoid.
Reading a fall in clicks as a fall in rank. An overview can lower click-through while position holds. Look at the results page before rewriting a page that still ranks.
Chasing every overview. Many informational queries end on the results page whoever is linked. Put first the queries where a click leads to revenue.
Switching off snippets by accident. Google’s preview controls apply to its AI features as they do to classic results[3], so a nosnippet rule added for one reason also makes the page ineligible as a supporting link, which requires eligibility to be shown with a snippet.
Blocking a token you misread. Robots rules for AI crawlers are often copied from a template without checking what each token governs. Read the vendor’s documentation first.
How QueryRev treats it.
Google AI Overviews is one of the AI surfaces QueryRev tracks, next to assistants such as ChatGPT, Perplexity and Gemini. An overview that links a competitor for a query your page ranks for becomes an Earn Citation opportunity. See GEO and AEO in QueryRev.
Questions people ask.
Can I keep my pages out of AI Overviews?
Google’s preview controls, such as nosnippet and max-snippet, limit which text of a page can be shown in Search, its AI features included. They limit classic snippets as well, so they are used with care.
Do AI Overviews appear for every query?
No. Google shows an overview when its systems judge that it adds value beyond the classic results, so many queries have none, and the same query can show one on one day and not on another.
Do AI Overviews take clicks from websites?
They can, on queries the overview answers in full. Google says that links shown in overviews get more clicks than the same page would as a classic listing for that query, which is why being one of the linked sources matters more than the position below it.
