What is AI search and how is it different from traditional search?

Traditional search returns a list of links and you pick one. AI search answers the question directly: Google AI Overviews and AI Mode, ChatGPT, Perplexity, and Claude read across sources and write a synthesized answer, often citing a few of them. The shift matters because the click is no longer guaranteed. Your brand can be read and even summarized without a visit, so the goal moves from ranking a page to being the source the answer cites. That is what generative engine optimization, structuring your site so AI cites it, is built for.

Do AI Overviews reduce website clicks?

Often yes, and our own data shows it. When an AI Overview answers the question above the blue links, many searchers never click through, so a page can gain impressions while losing clicks. We have seen exactly this on our own site: impressions up sharply while clicks fell over the same window. The response is not to fight the Overview but to be cited inside it, because a cited brand still earns the visit, the trust, and sometimes the click that a buried blue link no longer gets.

How often does AI search change?

Faster than traditional SEO did. In 2026 alone, Google AI Mode became the default experience, AI Overviews expanded to roughly half of all queries, ChatGPT introduced ads, and a Google core update reshaped rankings, all within months. The practical takeaway is that AI search is not a set-and-forget channel. We refresh this roundup every quarter because the surfaces, the engines, and the rules move on a quarterly rhythm, not a yearly one.

How do I keep my site visible as AI search evolves?

Cover the inputs that every AI engine reads, then measure citation across more than one of them. Ship an llms.txt summary, add complete schema markup, write short quotable answer passages, and keep your brand entity consistent across the web. Then track whether ChatGPT, Perplexity, Gemini, and Google AI Overviews actually cite you, not just where you rank in Google. The brands that stay visible treat AI search as a measured, ongoing practice, not a one-time setup.

AI Search Updates: What Changed in Q2 2026 and What It Means for You

AI Overviews now hit roughly half of searches and ChatGPT added ads. Here is what changed in AI search this quarter, and the three moves that keep your brand visible and cited.

TL;DR

AI search changed faster than traditional search ever did. As of Q2 2026, Google AI Mode is the default experience and AI Overviews appear on roughly half of all queries, ChatGPT has introduced ads, and the engine mix has widened: ChatGPT is still the largest source of AI referrals but its share is falling as Claude, Gemini, and Perplexity grow. For your business the headline is the same across all of them: searches that once produced a click now produce an AI answer, and the only durable way to stay visible is to be the source that answer cites. GEO means generative engine optimization, structuring your site so AI cites it, and AEO means answer engine optimization, winning the direct answer. This roundup tracks what shifted this quarter and the three concrete moves that keep your brand cited. We refresh it every quarter, because AI search moves on a quarterly rhythm.

The state of AI search right now

As of Q2 2026, AI search is no longer a side feature of Google. AI Mode is the default experience for a large share of searches, and AI Overviews, the AI-written answer box above the links, now appear on roughly half of all queries, up from under a third a year earlier.

The picture is no longer ChatGPT alone, either. ChatGPT is still the largest single source of AI referral traffic, but its share is falling as Claude, Gemini, and Perplexity each take a bigger slice. Optimizing for one engine now means leaving most of the surface uncovered.

The current AI-search landscape, in one paragraph. AI search in mid-2026 spans four major surfaces: Google AI Overviews and AI Mode, ChatGPT, Perplexity, and Claude. Google AI Mode has become a default experience and AI Overviews reach roughly half of all queries, so a large and growing share of searches end in a synthesized answer rather than a list of links. The engine mix has widened: ChatGPT still leads AI referrals but its share is declining as Claude rises to a clear second and Perplexity grows fastest of all. Advertising has entered the answer surface on Google and ChatGPT, while Perplexity has kept its answers ad-free. The unifying shift for any business is the same: visibility now means being the cited source inside an AI answer across several engines, not ranking a single page in one of them.

What changed in Q2 2026

Four shifts defined the quarter. Each one comes with a "so what" for your visibility.

Google AI Mode went mainstream. AI Mode is now a default search experience at very large scale. What it means: the synthesized answer is the first thing many users see, so being cited there outranks holding position 3 in the blue links.
AI Overviews expanded to about half of queries. Coverage jumped from under a third a year ago to roughly half. What it means: more of your impressions now sit under an Overview that may answer the question without a click, the exact dynamic dragging clicks on many sites.
ChatGPT introduced ads. OpenAI began running ads inside ChatGPT, and ads now appear alongside a meaningful share of Google AI Overviews too. What it means: the answer surface is becoming a paid surface, so an earned citation is more valuable now than it will be once ad inventory matures.
A Google core update reshaped rankings. A 2026 core update moved positions across many sites. What it means: if your traffic shifted this quarter, separate the core-update effect from the AI-Overview effect before you react, because the fixes differ.

What it means for your GEO and AEO strategy

The through-line is that impressions and clicks have decoupled. You can be more visible and get fewer clicks at the same time, so clicks alone no longer tell you whether AI search is working for you.

Two strategic consequences follow. First, measure citation, not just rank, because the answer box is where the decision now happens. Second, cover more than one engine, because no single assistant holds the audience the way Google once held search.

How AI Overviews change the click economics of search. An AI Overview answers the question at the top of the page, so the searcher often gets what they need without clicking any result. The visible effect in Search Console is counterintuitive: impressions rise because your page is shown under more Overviews, while clicks fall because fewer of those impressions convert to visits. We have watched this happen on our own site, with impressions up sharply over a window where clicks declined. The wrong reaction is to chase the lost click with a punchier title. The right one is to become the source the Overview cites, because a cited brand still earns trust, brand recall, and the higher-intent click, while an uncited page just inflates an impression count that never becomes a visit.

What to do this quarter

Three moves, in order, that match where AI search is now.

Make your pages quotable. Add short, self-contained answer passages an assistant can lift verbatim, plus complete schema markup and an llms.txt summary (a plain-text file AI crawlers read). These are the inputs every engine reads.
Measure citation across engines. Check whether ChatGPT, Perplexity, Gemini, and Google AI Overviews cite you, not just your Google rank. One engine is a quarter of the picture.
Separate the signals. If your numbers moved this quarter, split the core-update effect from the AI-Overview effect before acting, because one is a ranking problem and the other is a click-economics problem.

How we track this

We run generative engine optimization as a measured practice and refresh this roundup every quarter so it reflects the current state, not last year's.
