Google Is Killing Dynamic Search Ads in September 2026
June 2, 2026 · The Valley Marketing Group
If you're running Google Ads for your service business and nobody's touched your campaign settings lately, September 2026 is going to be a rude awakening.
Google is retiring Dynamic Search Ads (DSA) in September 2026 and replacing them with a format called AI Max. The transition is automatic. If you don't migrate on your own terms before September, Google will do it for you—which means less control over your budget and targeting. For HVAC companies, plumbers, electricians, and contractors who built their lead generation on DSA campaigns, this deadline matters now.
What Dynamic Search Ads Were—and Why Google Is Done with Them
Dynamic Search Ads let Google crawl your website and automatically generate ad headlines based on what it found. For service businesses with multiple service pages—water heater repair, AC installation, drain cleaning, emergency plumbing—DSA was a low-maintenance way to get coverage across all those searches without writing hundreds of individual ad variations.
Google is replacing DSA with AI Max, which does everything DSA did but adds real-time intent signals, Gemini-powered creative generation, and more granular controls. AI Max for Search campaigns exited beta on April 15, 2026, after adoption by hundreds of thousands of advertisers globally, according to Marketing Dive.
What AI Max Does Differently
AI Max combines three functions into one campaign structure:
- Search term matching — finds relevant queries beyond your keyword list using live intent signals
- Text customization — uses Gemini to dynamically generate contextually relevant headlines and descriptions for each search
- Final URL expansion — sends users to the most relevant page on your site, not just the URL you specified
The core difference from DSA: DSA was backward-looking (here's what your site says, here's an ad). AI Max is forward-looking (here's what this specific searcher needs right now). For a plumber, that means the system might match "water heater making noise at 2am" to your emergency repair page—not because you keyword-mapped it, but because the AI read the intent. Detailed in Google's official announcement.
The September 2026 Deadline: What Happens If You Do Nothing
Starting in September 2026, Google blocks creation of new DSA campaigns. Campaigns currently using DSA, automatically-created assets (ACA), or campaign-level broad match will be automatically upgraded to AI Max, according to Search Engine Land. What you might lose in a forced migration:
- Negative keyword lists — if your DSA was groomed over two years, Google's auto-migration may not preserve every exclusion
- Budget pacing control — Google changed how campaigns pace spend on March 1, 2026
- Campaign history continuity — migrating yourself lets you port historical conversion data; forced migration may not
What Else Changed Earlier in 2026
Call Ads deprecated (February 2026): Google removed the ability to create new call-only ads. Existing call ads stop receiving impressions in February 2027. For phone-first businesses like HVAC and plumbing, call ads were often the highest-converting format. The replacement is a responsive search ad with a call asset—it can still ring your phone, but your landing page now matters a lot more, per Choice OMG's analysis of 2026 Google Ads platform changes.
Budget pacing update (March 1, 2026): Campaigns with ad scheduling now pace toward the full 30.4x monthly cap across only the hours your schedule runs. If your campaign only ran weekdays 7am–7pm, it's now pacing to spend that full monthly budget in fewer hours than before—which can spike daily spend unexpectedly, per the same Choice OMG report.
Migrate Now, Not in September
The window to migrate on your own terms closes in September. Proactive migration lets you:
- Port historical conversion data, which AI Max uses to learn faster what a good lead looks like
- Set URL expansion exclusions so poorly-converting pages don't receive AI-generated traffic
- Test performance before the cutover instead of learning in real-time during peak season
According to Google's own data, AI Max campaigns using the full feature suite see an average of 7% more conversions or conversion value at a similar CPA or ROAS compared to standard campaigns, per Google Accelerate. Worth testing before it's forced on you.
The Real Risk: Feeding the AI Bad Signals
AI Max is only as good as the conversion signals you give it. If your only tracked conversion is a form fill or a clicked phone number—not a booked appointment—the AI optimizes for the cheap thing, not the thing that pays you.
Before migrating, connect your CRM. Tag which calls became booked jobs. Feed actual revenue signals back to Google. Our CRM automation agent syncs booking outcomes back to Google Ads so the campaign learns from real closed jobs, not just clicks.
Pre-Migration Checklist
- Audit your DSA campaigns for negative keywords worth preserving
- Review your ad schedule settings and recheck budget pacing since the March 1 change
- Set URL expansion exclusions for pages you don't want AI-generated traffic landing on
- Connect revenue signals from your CRM to Google Ads conversion tracking
- Create at least one test AI Max campaign to compare performance against DSA before forced migration
Use This as an Excuse to Audit Your Whole Account
Format changes are a useful forcing function. Campaigns that limped along in DSA will get worse in AI Max because the AI amplifies whatever signals you're already sending—good or bad. Our Google Ads agent runs a complete account review and flags the specific settings that'll hurt you in an AI Max environment before the September transition hits.
Running into September without a migration plan means handing Google control over your budget and targeting. Book a free 24-hour audit and we'll review your campaigns, flag your DSA dependencies, and build a migration plan before the deadline.
