Over the past few months, Google, Microsoft and Meta have each pulled another manual control off the dashboard. None of these changes is dramatic on its own. Taken together, they show where ad platform automation is heading: the platform decides more, and the advertiser sees less of how it decided. That is fine as long as someone is still checking the platform’s work. Too often, nobody is.
What the platforms took away this fall
Google. Google said in April that Search campaigns using automatically created assets or campaign-level broad match would be upgraded to AI Max for Search automatically starting in September, with Dynamic Search Ads following in February 2027. AI Max can match queries beyond your keyword list, write its own headlines and descriptions, and send a click to a different page on your site than the one you picked.
Microsoft. Since October 1, new campaigns using standalone Maximize Conversions, Maximize Conversion Value or Maximize Clicks can no longer set a Max CPC. Microsoft later told advertisers the restriction also covers Target CPA and Target ROAS, with a January 12 cutoff for API users and third-party tools. The company’s stated reason was to simplify bidding.
Meta. In late August, advertisers began seeing notices that excluding placements, platforms, devices and operating systems would no longer be available in their ad sets. By mid-October, Sales, Leads, Engagement and App promotion campaigns no longer allowed manual placement choices at the ad set level.
Three platforms, one direction: fewer manual bid controls. The bid cap, the placement list and the keyword boundary were how a buyer told the machine “no.” Each of those is now weaker or gone.
Ad platform automation works. For whom?
We use automated bidding every day, and in a lot of accounts it beats what a person could do by hand. Google says advertisers using the full AI Max feature set see an average of 7% more conversions or conversion value at a similar CPA or ROAS. We don’t dismiss that. But read the comparison closely: it’s full AI Max against AI Max with fewer features turned on, measured on Google’s internal data. It is not AI Max against a well-run campaign with tight controls.
Now look at the seller’s side. Meta’s third-quarter results showed advertising revenue of $63.1 billion, up 26% year over year, with ad impressions up 10% and the average price per ad up 14%. That isn’t evidence of anything improper. It is a reminder that the system optimizing your campaign belongs to the company selling you the inventory.
A platform’s algorithm is graded on what the platform can see: conversions it can attribute and budget it can deliver. It isn’t graded on your client’s margin, their brand-safety tolerance, or whether the lead it counted ever picked up the phone.
Our view: automation needs a second set of eyes
Our position is simple. Every time a platform removes a control, the advertiser needs to add a review step to replace it. When the platform holds the wheel, someone outside the platform has to watch the instruments.
This isn’t nostalgia for manual bidding. It’s separation of duties, the same principle any finance team applies to spending. The party spending the money shouldn’t be the only party grading how well it was spent. Platform dashboards report the platform’s version of success. An independent reviewer, whether that’s your in-house team or an outside partner, asks whether that version matches the client’s.
Our traders average 19 years in the business, and the pattern hasn’t changed in that time. The costly mistakes rarely come from a bad strategy. They come from a setting that changed quietly and nobody noticed for three weeks.
A pre-Black Friday automation audit
Budgets jump over Cyber Week, which is exactly when a loosened control costs the most. Here is what we’d check this week.
- Find the Google campaigns that were upgraded. Look for AI Max on any campaign that used automatically created assets or broad match. Pull the search terms report, and check final URL expansion. Turn it off where specific landing pages matter.
- Don’t strip Max CPC from existing Microsoft campaigns. Campaigns created before October 1 keep it, and removing it now can’t be undone. For new campaigns, set explicit CPA or ROAS targets, or use a portfolio strategy, which still accepts a Max CPC.
- Move Meta brand-safety exclusions to the account level. Placement value rules lower bids but don’t block delivery. Anything that must never run belongs in account-level placement controls.
- Write the guardrails down. For each client, record the CPA ceiling, the placements that are off-limits and the landing pages that can’t be swapped. If it isn’t written, nobody can check against it.
- Give change history an owner. Every major platform keeps a log of what changed and when. Put one named person on reading it weekly, and daily during Cyber Week.
Questions to ask whoever runs your media
If an outside partner runs your clients’ media, ask them three things. Which automated features are switched on in each account, and who approved them? How often does someone review search terms, placements and change history? And when a platform recommendation conflicts with the client’s goal, who makes the call?
Clear, specific answers mean someone is watching. Vague ones mean the platform is grading its own work.
More ad platform automation is coming, with Microsoft’s January cutoff and Google’s Dynamic Search Ads upgrade both on the calendar. If you’d like a second set of eyes on your accounts before the holiday rush, talk to our team.
