Search a simple question on Google and you will likely see, before any traditional result, an AI-generated block that already answers it directly. For purely informational questions, that means a large share of people never even scroll down to the classic results: they already have their answer. This is what is known as "zero-click" search, and while it sounds alarming, it does not mean SEO has stopped working: it means you need to understand what role your site plays inside that summary, not just below it.
First: not every search triggers an AI Overview
Google reserves these summaries mostly for clear informational questions, not for transactional searches ("buy", "price", "near me") or for specific brands or businesses. If most of your traffic comes from purchase-intent searches, the direct impact is smaller than it first looks; if it comes from generic "how to..." questions, it is worth paying closer attention.
Being cited inside the summary still generates value
Even when the user does not click through, being one of the sources cited inside the AI Overview still builds the perception that your brand is an authority on that topic, which can translate into direct clicks later on when that same person searches for something more specific. The goal stops being just "get the click now" and starts including "get recognised as a trustworthy source."
What content format is most likely to get cited
AI Overviews prefer concrete, well-bounded fragments: a clear definition in two sentences, a numbered list, a comparison table, a fact with its source. A long paragraph with no structure, however good the underlying content, is much harder to extract cleanly than a short, direct answer placed right after the heading that raises the question.
What you cannot control (and need to accept)
You cannot decide whether Google triggers an AI Overview for a given search, or exactly which sources it cites: that is decided by the system itself, based on its own criteria, which change frequently. The only thing within your control is writing in a way that, if Google decides to extract something, what gets extracted is clear, correct, and easy to isolate from the rest of the text.
Frequently asked questions
Will AI Overviews eventually replace normal results entirely?
For now they coexist, appearing only for certain informational searches. No one can guarantee how this will evolve, but real traffic to classic results still exists today, even on searches where a summary appears above them.
How do I know if my site is being cited in these summaries?
Right now it is hard to measure systematically because not every search engine reports it clearly in its analytics tools; it is worth doing periodic manual searches of your key terms and checking by eye.
Should I stop writing long content because of this?
No: long content is still necessary to demonstrate authority and cover the topic in depth. What is worth adding is a short, clear answer at the start of each section, without removing the deeper explanation that follows.
