Amazon sells ChatGPT ads, Meta buys for you, and bots ate your retargeting list
Four things happened in one week that change how digital marketing budgets get spent and measured. None of them are incremental.
Amazon is now selling ads inside ChatGPT
On 10 September, Amazon Ads and OpenAI launched a US pilot letting select advertisers extend campaigns already running in Amazon DSP into ChatGPT. Delta Vacations is the first named tester. Amazon’s ad business passed $70bn on a trailing twelve-month basis. ChatGPT’s ad business crossed a $1bn annualised run rate in early September, and eMarketer’s Nate Elliott described OpenAI as “still trying to build out even many of the basics of a functional ad sales operation.” Amazon supplies the sales infrastructure OpenAI hasn’t built yet.
Neither party has disclosed how a conversational impression is measured, deduplicated against other DSP placements, or connected to a purchase. If you already buy through Amazon DSP, ask your rep what ChatGPT placements will report back before you extend a campaign. Retail conversion data is why your Amazon spend gets approved internally, and nobody has confirmed whether these impressions carry any of it.
Meta’s Muse agent completes purchases. Your checkout can’t tell it apart from a bot.
Meta released Muse on 8 September. It’s a personal AI agent running on its own cloud machine with a browser, file system, and terminal, reachable through WhatsApp and dedicated apps. US only for now, free for most use with paid tiers above that. It completes purchases using a one-time card generated through Stripe Link, with a separate program called Sentinel approving anything that leaves the machine.
Code analysis published three hours after launch found three checkout modes: browser mode (types card details into any open web form), Shopify mode (runs over APIs and most likely the Universal Commerce Protocol), and Stripe Link mode for already-integrated sites. Only 26 public websites out of three million scanned carried UCP files as of May. Merchants have no way to distinguish a delegated buying agent from a scraper. As one analyst noted, an agent typing card details into a checkout form “looks like the spam bots they have been fighting for years.” Meta says Muse conversations stay out of its ad systems, which walls off its richest purchase-intent signal from a business that made $59.36bn in ad revenue last quarter.
Check what your bot protection does to an automated visitor that fills a checkout form correctly. Google, Microsoft, and now Meta are all routing buying agents at merchant sites. Blocking them means blocking the sale.
More than half of web requests are bots. Your retargeting budget doesn’t know that.
Digiday research published 8 September cites Cloudflare data putting bots and AI agents past 50% of all web requests. GoFish reports clients seeing bot traffic up 80% year on year, and the retargeting adjustments made in response pushed CPMs up an average of 20%. One client saw CPA spike through Q4 and into this year.
The problem isn’t advertisers versus platforms. It’s advertisers versus advertisers. Mattress brand Mellow Sleep reports AI assistants send traffic that converts several times better than site average. John Lewis has watched agentic searches grow from 0.3% to 2.5% of visits in a year. The mechanism is the retargeting pool: when a growing share of visitors aren’t people, audience lists stop describing potential buyers and start describing requests. Budgets are already shifting toward social and retail media where a login establishes who the visitor actually is. Lunio found only 5.3% of marketers use invalid traffic tools while 75.6% say they lose budget to bots. Pull the last quarter of retargeting pool growth against actual conversions from that pool. If the audience is growing faster than the revenue it produces, you’re probably paying rising CPMs to reach crawlers.
Publishers spent $113m in July buying back search traffic Google removed
Similarweb data reported by Adweek on 9 September shows the hundred largest media publishers spent an estimated $113m on paid search in July 2026, up 41% year on year and 274% over three years. The traffic it bought, 23.7m visits, grew 148% over the same three years, meaning spend is rising faster than what it buys. Forbes alone accounted for $72.2m, roughly two thirds of the total, while its organic search traffic fell 26.7% year on year. CNN fell 28.9%, USA Today 24.1%. The New York Times spent $11.3m, more than double a year earlier. The money flows back into the auction run by the company whose result page changes removed the organic traffic in the first place.
The same day, two independent datasets found People Also Ask, one of the last organic units still routing clicks to third-party sites, has been almost entirely absorbed by AI Overviews: 86% in August, 97% by early September, against about 12% fourteen months ago. USA Today is building a 23 to 30 person audience team. The New York Times has created a role overseeing AI and off-platform discovery. If your content strategy still counts on People Also Ask or informational organic traffic, the largest publishers in the world have already priced in that it’s gone and are paying to replace it.
