Paid search is now a three-surface business, and the holiday season will be its first real test. Adthena released its Holiday AI Paid Search Report on November 4, 2026, tracking paid search across ChatGPT, Google AI Overviews and AI Mode, and traditional Google Search. The headline number is the scale of ChatGPT advertising: Adthena tracked 204,489 ChatGPT ad placements between June and September 2026, with the advertiser base growing nearly six times in two months. For SEOs and link builders, the message is that the answers themselves are now inventory, and the pages that get cited are sitting next to paid placements.
Adthena's report is the first systematic count of how paid search now splits across three distinct search environments. On ChatGPT, the 204,489 placements recorded from June to September show an ad business scaling fast from a standing start, since OpenAI only began selling advertising on the platform this year. The advertiser base growing nearly sixfold in two months suggests that early testing has turned into real budget commitments ahead of the peak shopping season, not a handful of experiments.
On Google's side, the growth is just as steep. AI Overview appearances grew 536 percent in Australia, 160 percent in the UK and EU, and 89 percent in the US year over year across the markets Adthena monitors. Paid ads now regularly appear inside Google's AI answers, with Adthena identifying 175,100 paid placements in the US, concentrated in apparel and consumer electronics. Those two categories are exactly where holiday spending concentrates, so the first AI-driven holiday season will be fought inside the answer box as much as below it.
For years the SEO brief was simple: rank, then convert the click. The Adthena numbers describe a results page where the click itself is contested. A shopper who gets an answer with products, prices, and paid placements inside it may never reach the organic listings at all. That does not make organic rankings irrelevant. It makes the citation the new first position, because the page that is cited inside an AI answer is the one the shopper sees before any list of ten blue links.
Link builders should read the report as a budgeting signal as much as a search signal. When advertisers pay to appear inside answers, the commercial value of being cited rises, and so does the competition for the underlying pages. Original product data, clear pricing, trustworthy reviews, and pages that answer buying questions in quotable language are the assets that both the AI and the advertiser want to sit next to. A page that earns a citation in an AI answer is now doing the job a top-three ranking used to do, in front of an audience that is already being monetised.
The number to watch is Adthena's own forecast, which the report frames as a vendor prediction: Google's AI box will carry more retail ad volume than the traditional results within 18 months. If that proves right, the organic listing becomes the second place shoppers look, not the first. SEOs should track three things through the holidays: whether their pages are cited inside AI answers for buying queries, whether paid placements appear alongside those citations, and whether referral traffic from AI surfaces grows or shrinks as the ads scale.
The practical work does not change much, but its urgency does. Keep product and category pages accurate, structured, and genuinely useful, because an AI answer will quote the clearest source it can find. Build the kind of original data and expert content that other writers cite, because citations are what put a brand inside the answer. And measure AI referral traffic separately from classic organic, or the most important shift of this holiday season will be invisible in the reports. The full Adthena report is available from the company's website, and it is worth reading in full before the peak season, because the category-level detail will tell a retailer exactly where the paid pressure is building in their own market.
