At the I/O conference on May 19th, Google announced the biggest change to Search in over 25 years, and almost nobody outside the SEO industry noticed. The “Intelligent Search Box” pushes AI Overviews above every result page, encourages follow-up questions inside Google’s own AI Mode, and trains users to stop clicking on the actual web. The shift is real. The cost to every site that depends on Google for traffic is also real, and it is happening right now.
I run a handful of small sites that get a meaningful slice of their readers from organic search. Over the last 18 months I have watched the click-through rate (the percentage of people who see a search result and actually click it) on my own pages fall from a stable 6-8% down to 1.5-2.5% for the same keywords. The page that used to rank first now sits below an AI Overview that answers the question directly. The reader never scrolls. That is what Google just upgraded at I/O: the box that decides whether the open web gets a visitor at all.
What Google actually announced
Three changes matter, and they reinforce each other.
First, the AI Overview now sits above the regular blue links on more queries. The Overview is the answer. The links are the receipt. In practice the receipts get read a lot less than the answer.
Second, “AI Mode” (a separate search experience that runs entirely on Gemini, Google’s family of large language models) now has a follow-up question box built into the Overview. The design encourages you to ask your next question inside Google’s interface, not on the website you would have visited before.
Third, Search now supports what Google is calling “search agents,” which are persistent profiles that carry context across sessions. The longer you stay inside AI Mode, the more Google knows about what you are working on, and the harder it becomes for an outside site to win that click.
None of this is hidden. Google published the announcement on its own blog. The framing is “conversational.” The mechanics are “stay on Google.”
Why this is different from past search updates
Google has changed Search many times. Penguin (a 2012 update that demoted sites with spammy backlinks) hurt link farms. Panda (a 2011 update that demoted thin content) hurt scrapers. The Helpful Content Update of 2022-2023 rewarded sites that answered real questions. In each of those cases, the web got worse for some players and better for others, but the underlying deal held: Google sent traffic to outside pages, and those pages earned it by being a solid answer.
The Intelligent Search Box breaks that deal. The Overview is the answer, and the answer lives on Google. If the Overview is good enough, the reader has no reason to click. The “ten blue links” (the classic list of web results Google used to show) are still on the page, but they have been pushed below the fold (the part of the page you have to scroll to see), and the fold gets pushed further down every quarter.
For a publisher like me, the math is straightforward. If my click-through rate was 7% last year and it is 2% this year, I am getting about 30% of the readers I used to for the same ranking. The page that used to support a small subscription business now supports a hobby.
The monopoly question nobody wants to ask
Google’s search market share in the US is around 90%. In most of Europe it is over 90%. That is not “popular search engine” territory. That is “default search engine for the internet” territory. When the default flips from “send the user to a website” to “answer the user in the box,” the entire business model of the open web flips with it.
The Department of Justice (DOJ) antitrust case against Google, which ended in 2024 with a ruling that Google holds an illegal monopoly in search, did not stop this rollout. The remedies proposed in 2025 included potential divestiture of Chrome, the browser Google ships, and changes to default-search contracts with Apple and Android device makers. None of those remedies touch the AI Overview directly. The AI Overview is the search product itself, and the court has not told Google how to design its own product.
In the European Union, the Digital Markets Act (DMA, a 2022 law that forces the largest “gatekeeper” platforms to interoperate with smaller rivals) has more teeth on paper, but enforcement has been slow and the AI Overview is presented as a feature, not a gatekeeper action. Regulators are still arguing about whether to classify AI Overviews as “self-preferencing” (the legal term for a platform favoring its own products over competitors), and Google is rolling the feature out across all 27 member states while the lawyers debate.
So in practice, the change is happening with no serious counterweight. The companies that built their businesses on Google sending them traffic are watching that traffic drain out, and there is no procedural way to slow it down.
What I would tell past me
If I could send a message back to the version of me that wrote a post in 2023 and expected Google to send 10,000 readers over the next 24 months, I would say three things.
- Do not build a business on a single traffic source that you do not control. The deal between Google and publishers has changed twice in five years. The next change is already in the pipeline. Own at least one distribution channel that does not depend on Google’s ranking decisions: an email list, a direct RSS feed (a subscription format that pushes new posts to readers automatically), a community, a podcast.
- Invest in the question, not the keyword. The sites that are holding up under AI Overview are the ones that answer a question the AI cannot fully answer in two paragraphs. Niche expertise, primary reporting (content based on the publisher’s own original interviews or experiments), and lived experience still earn the click. Generic “what is X” posts do not.
- Track click-through rate by query, not just by page. A page that ranks first but gets 1% CTR is a different problem from a page that ranks fifth and gets 6%. The first page is being cannibalized by the Overview above it. Knowing which queries are now Overview-dominated tells you where to redirect your writing.
- Watch the “zero-click” queries first. A growing share of Google searches in 2025 ended without any click at all, with the Overview fully answering the question. Build a separate dashboard for those queries, because the day they shift from “informational” to “your topic” is the day your traffic halves.
Trade-offs
Pushing back on the AI Overview is not free. Search engines are still the largest source of discovery on the open web, and “rank in Google” is still the single most useful marketing activity most small publishers can do. The trade-off is between short-term traffic (which the Overview is killing) and the long-term cost of disappearing from a channel that still drives 40-60% of new-reader discovery for most content sites.
A direct pivot away from Google takes time. Building an email list of 10,000 readers who open your newsletter takes 1-2 years of consistent publishing. Building a community on a platform you own (a forum, a Discord, a paid Substack, a private RSS reader like Feedbin) takes similar effort. The cost is not just the time to build the channel, it is the content you stop writing while you are building it. The opportunity cost (the value of what you give up to do something else) is real.
There is also the chance that the Overview is genuinely better at answering the user’s question, and that fighting it is a losing move. Some publishers are leaning into the Overview, treating it as a feature that surfaces their content even when readers do not click. That is a defensible position if you are an authoritative source and Google chooses to cite you. It is not a defensible position if your business model depends on the click.
If you are a single-author site with one or two writers and your income is mostly ad-supported, the answer is clear: diversify off Google now, before the next I/O keynote makes the problem worse. If you are a large publisher with a brand readers seek out directly, the calculus is different. The Overview still drives discovery, and the readers who do click through are higher-intent than the old organic traffic. For most sites in the middle, the move is the same: stop treating Google as your landlord, and start treating it as one of several channels you rent space on.
Bottom line
Google’s Intelligent Search Box is the biggest change to Search in over 25 years, and the change is bad for every site that depends on organic traffic. The fix is not to publish more. The fix is to own a distribution channel that does not depend on Google’s ranking decisions, and to write the kind of content the AI Overview cannot fully answer in two paragraphs. If you only do one thing from this article, set up an email list today. The rest can wait.
