Marketing: ad tools now draft the changes and wait for a yes

Marketing's ad tools are turning into agents that draft the work and wait for an owner's yes. Between mid-September and mid-October 2026, Meta gave the assistant inside its ad-buying tool a memory of your past campaigns and began testing a version that moves budgets itself, and OpenAI turned a click on a ChatGPT ad into a chat with the brand's own AI agent. Google moved older search campaigns into its AI-run format automatically. For a small business, the skill that matters now is deciding what the agent may do alone.

Six weeks after Marketing: agency prices fall as the platforms take the routine work, the platforms have gone from writing the account report to proposing the changes. Two other things need attention before the end of October: Meta's new terms for business accounts, and what the largest agency groups say AI is for.

The ad account learns to act

At Advertising Week in New York on 6 October 2026, Meta said the AI assistant inside Ads Manager, the tool businesses use to buy Facebook and Instagram ads, remembers past conversations and reads your campaign history (Social Media Today and other trade outlets, 6 to 8 October). Uploading brand and strategy documents is in testing, as is the bigger step: the assistant setting up campaigns and moving budget and targeting on its own. Meta gave no country list.

A week earlier, on 29 September, Meta launched Muse for Small Business, an agent that connects to about 15 business apps, from online-store and payment software to bookkeeping, and can pull them into one monthly review (Reuters and TechCrunch, 29 September). It is free for most uses, must get the owner's approval before it publishes, sends or spends anything, and is open only in the US and Canada.

OpenAI took the same idea into the ad itself. On 16 September it began a small test of Sponsored Agents: click a ChatGPT ad and a labeled chat opens with the advertiser's own AI agent, kept apart from ChatGPT's answers, with the advertiser seeing totals and no transcripts (OpenAI, 16 September). Retailers such as Lowe's and Best Buy are in the test; it is US-only and has no published price. If the format spreads, the brand answers for what its agent says, the way it answers for its ad copy today.

The tools already live keep a person's approval at the point where money moves or something goes public; the versions that act alone are in testing. That approval is becoming the real job.

Google moved your campaigns for you

Through September 2026, Google switched Search campaigns that used campaign-wide broad match (a setting that lets an ad show for searches only loosely related to its keywords) or automatically written ad text into AI Max, its setting where Google's AI picks the searches and writes the ads (Google's announcement of 12 August, reported by Search Engine Land and others). There was no opt-out from the move. Turning AI Max off afterward restores your settings, but keywords changed in the meantime must be restored by hand. Dynamic Search Ads, the campaigns that build headlines from your website's pages, follow from 1 February 2027.

On 23 September Google also extended AI Brief, its tool for setting up a campaign from a written description, to Spanish, Portuguese, German, French, Italian, Dutch and Japanese, in closed testing (exchange4media, 23 September). Advertisers working in Spanish or Portuguese can now ask to join.

Meta's terms change on 30 October

Meta's new Commercial Terms for business accounts take effect on 30 October 2026. After legal experts told Nieman Lab the draft could override robots.txt, the file that tells automated crawlers what they may read on your site, Meta removed the wording that let it train AI on content crawled from the websites linked to business accounts, and limited that content to "advertising and business products" (Quartz and ContentGrip, 17 to 19 October). The right to crawl the linked site stays, with no opt-out. A 19 October check by Pebblous, a Korean AI blog, found the change only in the US English edition, with the UK edition still carrying the old wording.

The agencies' new pitch

On 13 October Publicis, the French group that is one of the world's largest advertising companies, told investors it will use AI agents to handle about a quarter of manual, repetitive tasks, set no headcount target alongside that goal, and said it is still hiring (mi-3, an Australian marketing trade outlet, 14 October). In effect, the pitch is more output for the same fee.

What it means for you

The platforms draft the changes and wait for a yes. Whoever gives that yes, you or the agency you pay, needs written limits: which changes the agent may make, up to what spend, and who checks the result. The UK's ad regulator already judges AI work as if a person made it. In September the Advertising Standards Authority ruled against a gambling ad because its AI-generated character looked under 25, the same age rule that applies to a real actor; the regulator's own AI monitoring caught it (the law firm CMS, summarizing a ruling of 16 September).

When your agency renews, expect the Publicis pitch. Ask which tasks the agents do and what the people on your account spend their hours on instead.

What to do about it

First, before 30 October, read Meta's Commercial Terms in the edition for your country, and decide whether your website should stay linked to your business account on those terms.

Second, open your Google Ads account and check which Search campaigns moved to AI Max in September. Compare their cost per sale with August and add the search terms and pages you want excluded. If you run Dynamic Search Ads, upgrade one campaign yourself before February so you learn the settings while they are your choice.

For Meta's action-taking assistant and Sponsored Agents: watch, don't act yet. Hand the assistant budget control only once the feature leaves testing in your own account.
