In our last article ‘Search is Dead, Long Live Discovery’, we explored how the traditional familiar blue-link Google search results are already being suppressed by AI Overviews, ruining your organic traffic and answering questions before users ever see your brand.
The next chapter is bigger, and more unsettling.
Google has begun rolling out Personal Intelligence — an opt-in system that connects your Gmail, your purchase receipts, your Photos library and your Maps history to deliver responses that are, in Google's own words, uniquely relevant to you. For now, it's voluntary and US-only. But the direction of travel is unmistakable. Every major BigTech platform is converging on the same end game: absorb as much of your personal data as possible and become the one interface you need for everything.
If organic listings are already being suppressed by AI Overviews — what happens to paid ads? Do they get pushed down too? Or do they get pulled into the chat window itself, woven into AI-generated answers backed up by your emails and purchase history?
The answer is uncomfortable. Yet it will define the economics of digital advertising for the next decade.
And the early signals are already visible.
Not so long ago, the path to purchase was predictable.
A customer would run 5, 6, maybe 8 searches across a few days — comparing options, reading reviews, clicking a handful of paid ads along the way. Each of those searches was an opportunity. Each click was a touchpoint.
The entire architecture of Google Ads was built on the assumption that people browse, deliberate and eventually convert. That assumption is now being dismantled in real time.
A user looking for an e-commerce consultant, a new boiler, or the best accounting software can now open ChatGPT, Perplexity, or Google’s own AI Mode and — in a single conversational prompt — receive shortlisted providers, price comparisons, pros and cons, and a recommendation.
One query has collapsed what used to be a multi-session research journey.
For all website owners - and particularly PPC advertisers - that compression has direct and measurable consequences:
Fewer high-intent searches reaching the SERP at all
Reduced top- and mid-funnel keyword volume as early-stage research migrates to AI tools
Collapse of long-tail keyword breadth, as those exploratory queries never reach Google
Shorter, more transactional queries from users who have already done their research inside an AI
This shift is already visible in the data.
According to research from Arc Intermedia, roughly 36% of generative AI users now say they have replaced traditional search with an AI assistant for at least some queries.
These are not distant trends. They are happening now, and they are accelerating.
Even for the searches that do still arrive at Google, the landscape that greets them looks nothing like it did in 2022.
AI Overviews — the large, AI-generated summaries that now appear at the top of many results pages — have fundamentally altered how the SERP is structured, and they have done so at the direct expense of organic listings and paid placements.
The numbers are stark.
Research by Seer Interactive, which analysed over 3,100 informational queries across 42 organisations and tracked more than 25 million impressions between mid-2024 and September 2025, found that paid click-through rates on queries featuring an AI Overview fell by 68% — from 19.7% down to just 6.34%. Organic CTR dropped 61% over the same period. A further December 2025 study from Ahrefs found that when an AI Overview appears, the click-through rate for the top-ranking organic result falls by around 58%.
You cannot simply bid your way back from that.
When an AI Overview occupies the top of the page, ads get pushed below the fold, your impression share reduces, and the users who do click are already filtered through a layer of AI-generated research. That’s not entirely bad — those clicks carry stronger intent — but the visibility loss is real and your economics have to shift significantly.
There is a survival path, but it requires a different kind of investment.
Brands that are cited inside AI Overviews earn 35% more organic clicks and 91% more paid clicks compared to those that are not cited at all, according to the same Seer Interactive research. In other words, being mentioned in the AI answer effectively is the new signal of trust - but you cannot claim it purely through ad spend.
Google is not sitting still while search volumes erode. It cannot afford to. In 2025, Google reported its first full year above $400 billion in annual revenue, with search ad revenue growing 17% year-on-year.
That performance, impressive as it is, was maintained in part through a deliberate strategy of expanding where ads can appear and simultaneously reducing the visibility advertisers have into where their conversions are actually coming from.
Google screwed us all over in favour of their own revenues.
The cloaked Performance Max and AI Max campaigns now serve ads across a sprawling network that extends well beyond search:
Traditional Search results
YouTube pre-roll and in-feed placements
Display network and Gmail
Google Maps and Waze’s promoted navigation pins
Discover feed and AI-powered placements
AI Mode in Search — where Google is actively testing ad placements within AI-generated responses
This expansion artificially maintains click and conversion volume even as pure search demand shrinks.
But it comes with a significant catch: advertisers are increasingly unable to see which specific placements are driving results, which queries triggered their ads, and how much of their attributed conversion data is brand vs non-brand. The reporting gets more opaque as the inventory expands. Some advertisers report that campaign “volume” feels stable — but what they’re often looking at is a blended signal across multiple channels, rather than evidence that high-intent search traffic is holding up.
Google is eroding your control in favour of the ‘trust me, bro’ trademark.
The cost side of the equation has moved too. WordStream’s Sept 2025 benchmark data showed average Google Ads CPCs rising to £5.26 — up nearly 13% year-on-year — with 87% of industries seeing increases.
Meanwhile, paid CTRs continue to fall. You are paying more for fewer clicks. That’s not a sustainable trajectory for advertisers who don’t adjust their strategy.
Here is where the story takes its most significant turn — and where our previous article on the death of blue-link search connects directly to the future of paid advertising.
In March 2026, Google officially confirmed the expansion of what it calls Personal Intelligence — a system that securely connects your Google apps (Gmail, Google Photos, Maps history, purchase receipts and more) to deliver responses that are, in Google’s own words, “uniquely relevant to you.” This is now live for free-tier US users across AI Mode in Search, the Gemini app and Gemini in Chrome.
What does this mean in practice? Google’s AI no longer just knows what you searched for today.
It knows what you bought last month, where you flew last summer, what’s in your inbox and what your previous Google Photos show about your lifestyle and interests. When it serves a recommendation — whether organic or paid — it can do so with a depth of contextual understanding that no keyword-matched ad has ever been able to match.
For advertisers, the implications are profound.
The intent signals embedded inside a Personal Intelligence-driven conversation are far richer than a single keyword typed into a search box. When someone asks Gemini to help them find running shoes that work with flat feet, the AI already knows their shoe size from a previous order, their usual brands and their price bracket.
The positive for brands is that a sponsored placement in that context is worth exponentially more than a generic PPC click. Industry sources quoted in coverage of Google’s advertising roadmap put it plainly: advertising within AI is going to open a new way of targeting.
Google has been explicit that Personal Intelligence data from Gmail, Photos and YouTube is not sold or shared with third-party advertisers, and that users maintain full opt-in control. But the system still creates a rich behavioural signal that feeds Google’s own ad models — and those models are only going to get smarter as more users connect more apps.
Paid search was built on owning the top of the funnel.
You could spread awareness of your brand name through top-, middle- and longer-tail keyword bids, thus establishing a feeling that you are the right choice.
But now, the user’s early-stage research has migrated to AI tools. Product discovery increasingly happens inside LLM reasoning, on TikTok or through AI-curated recommendation surfaces. Evaluation — the comparison stage where purchase intent crystallises — now often takes place inside a single AI conversation rather than across multiple searches and ad clicks. By the time a user arrives at a Google search, they are often already near the bottom of the funnel, looking for the transaction rather than the research.
For brands willing to accept a smaller click pool with better CTR, this could represent an opportunity. For those still chasing volume with broad match keywords and informational-query bids, it is an accelerating drain on budget.
Google Ads is not dead. But the version of Google Ads that worked reliably in 2021 — broad keywords, high click volumes, multiple funnel touchpoints — is being retired by the AI transformation happening around it.
The advertisers who will win in this environment are those who understand that paid search is now one part of a much larger AI-visibility puzzle. Getting cited in AI Overviews matters. Brand authority matters. First-party data matters. Landing page efficiency matters more than ever when you’re paying more per click for users who arrive further down the funnel. And understanding exactly what Google’s increasingly opaque campaign types are and are not delivering matters enormously.
The search landscape is not slowing down its evolution to wait for anyone to catch up. The brands that treat this moment as a strategic inflection point — rather than a passing disruption to be waited out — are the ones that will emerge from it with competitive advantage intact.
