Google Is Killing Dynamic Search Ads. Here's What You Actually Need to Know.
If you run Google Ads and you haven't heard about this yet, pay attention. Google just announced the retirement of Dynamic Search Ads (DSA), and starting September 2026, every remaining DSA campaign in your account will be automatically upgraded to something called AI Max. Whether you're ready or not (Google Ads Blog).
This isn't a minor tweak. It's a platform-level shift in how Search campaigns work, how your budget gets spent, and how much control you actually have. And the way Google is framing it versus what's actually happening in real accounts are two very different things. Let me break it down properly.
What's Actually Happening
Dynamic Search Ads have been around for years. The idea was simple: instead of manually building keyword lists, DSA would crawl your website, read your page content, and automatically generate ads to match what people were searching for. It was a blunt instrument, but a useful one, especially for large eCommerce catalogues or advertisers who couldn't maintain granular keyword structures (Search Engine Land).
AI Max is the replacement, and it goes much further. Where DSA read your landing pages and matched ads from there, AI Max layers in your existing ad copy, your keywords, and real-time intent signals to generate headlines, choose landing pages, and decide which searches to show your ad for, all on the fly (Google Ads Blog).
Google's headline number is that AI Max delivers 7% more conversions at a similar cost when using the full feature suite compared to search term matching alone (Google Ads Blog). That sounds reasonable until you start digging into what "full feature suite" means in practice.
Why This Is a Bigger Deal Than It Looks
Three things get auto-upgraded in September:
DSA campaigns — converted to AI Max with all features switched on by default
Automatically created assets (ACA) — AI-generated ad copy becomes more systematic
Campaign-level broad match — AI Max handles the matching logic entirely
The critical detail most advertisers will miss: all three AI Max features are on by default after migration (NiCreated).
That includes final URL expansion, which means Google can send traffic to any page on your site, not just the landing page you specified. It includes text customisation, meaning Google can write headlines you've never seen and never approved. And it includes expanded search term matching, meaning your ads can appear for searches you'd never have chosen yourself. Unless you actively configure the guardrails, you're running wide open.
What the Independent Data Says
Google's 7% uplift claim looks good on paper. Real-world data tells a more complicated story. One independent analysis tracked over 30,000 search terms activated by AI Max features. Of those, 99% generated zero conversions. A separate study across more than 250 retail campaigns found AI Max delivered conversions at roughly 35% lower ROAS than traditional match types. Another advertiser documented a cost per conversion of $100.37 under AI Max versus $43.97 under phrase match over a four-month period (NiCreated).
That's not an argument against AI Max categorically. For high-volume eCommerce accounts with strong tracking, clean creative assets, and well-structured campaigns, there are genuine performance gains available. But for service businesses, lead gen accounts, and anyone operating on tighter margins, the picture is far less clear.
The gap between Google's number and real-world performance isn't new. We saw the same thing with Smart Shopping becoming Performance Max (Search Engine Journal). The pattern is consistent: fewer campaign types, more automation, less manual control, and default settings configured for platform-level volume rather than advertiser-level efficiency.
What People Are Overestimating (and Getting Wrong)
There are two failure modes I'm already seeing in the commentary around this.
The first is panic. AI Max isn't going to destroy every account. The technology is genuinely capable. If you have clean conversion tracking, strong landing pages, and well-structured campaigns feeding the system, AI Max can find incremental volume you weren't capturing before. The issue isn't automation. The issue is handing over control without configuring it intelligently.
The second is blind trust. Accepting Google's default upgrade and calling it a win is just as dangerous. The defaults are not built for your account. They're built for the average account at scale. URL expansion is one of the most misunderstood risks here. Traffic landing on the wrong page because Google "chose" it for you is a real problem that shows up quietly in your cost data, not loudly in a platform alert.
The smarter framing: AI Max is a tool. Like every Google tool released in the last five years, it performs significantly better when it's configured properly, fed with quality inputs, and monitored against actual business outcomes rather than platform-reported metrics.
Good tracking is no longer optional. If AI Max is making creative decisions, targeting decisions, and landing page decisions simultaneously, and you can't see what it's doing at the query level, you're flying without instruments. Conversion data is the only signal that keeps the system honest.
The Migration Is Automatic. The Results Are Not.
The DSA retirement is the clearest signal yet that Google is moving toward a world with fewer manual levers and more AI-driven automation. That's not inherently bad. But it does mean the job of running Google Ads well has changed: it's now about knowing which defaults to override, which automation features to trust, and where to keep a human hand on the wheel. The September auto-upgrade isn't optional. The quality of your migration is.
Dadek Digital helps businesses navigate exactly these kinds of platform shifts, from auditing existing campaign structures to configuring AI Max properly so automation works for your account, not against it. If your DSA campaigns are live and you haven't reviewed them yet, now is the right time.
