On April 15, 2026, Google confirmed what many PPC managers had been expecting: Dynamic Search Ads are going away. Starting in September 2026, all DSA campaigns will be automatically upgraded to AI Max for Search. There is no opt out.
If DSA campaigns represent a meaningful portion of your search budget, this is not something you can ignore until September and hope for the best. The auto upgrade will happen whether you are ready or not. The difference is whether you control the transition or let Google handle it for you.
In our experience managing campaigns for multiple clients, forced platform migrations almost always cause short term performance dips when advertisers are unprepared. This guide walks you through exactly what is changing, what the risks are, and how to migrate your DSA campaigns to Google Ads AI Max on your own timeline.
What is happening to Dynamic Search Ads
Google officially announced that AI Max for Search has exited beta and is now generally available. Alongside that announcement, Google confirmed that Dynamic Search Ads will be retired as a standalone campaign format. All DSA campaigns will be automatically upgraded to AI Max starting in September 2026.
Voluntary migration tools started rolling out in mid April 2026. This means you have roughly five months to migrate on your own terms before the forced upgrade kicks in.
This follows a pattern we have seen before with Google. The Smart Shopping to Performance Max migration in 2022 gave advertisers about nine months of runway. This time, the window is shorter: roughly five and a half months from announcement to auto upgrade. If you manage high volume accounts where DSA drives a significant share of traffic, that timeline is tight.
Why this matters for your team
Agencies and in house teams managing more than ten accounts should start planning now. The September 2026 auto upgrade date will not move. Accounts where DSA represents more than 50% of the search mix, particularly lead generation and non ecommerce accounts, face the highest operational risk during migration.
DSA vs AI Max for Search: the key differences
Before you migrate, it helps to understand what is actually changing under the hood. AI Max for Search is not just a rebrand of DSA. It is a fundamentally different system with more automation and less granular control.
| Dimension | Dynamic Search Ads | AI Max for Search |
|---|---|---|
| Ad generation | Headlines auto generated from your site content | Full ad copy (headlines + descriptions) generated and customized by AI |
| Targeting | Based on your website content and page feeds | Broader matching using AI signals, keyword expansion beyond your site |
| URL control | Target specific pages or categories with page feeds | AI selects landing pages dynamically, less direct URL control |
| Keyword matching | Tied to your website content | Applies broad match intelligence, can match queries beyond site content |
| Reporting | Standard search term reports | AI generated text guidelines visible, placement reports now segmentable by network |
| Control level | Moderate: you set targets, Google generates ads | Lower: AI handles more decisions, text guidelines let you set guardrails |
The core tradeoff is clear. AI Max offers broader reach and potentially better performance through Google's machine learning. But you give up the URL level control and targeting precision that many DSA users relied on. For lead generation accounts and multi brand portfolios, this shift demands careful planning.
The migration timeline: what happens when
April 15, 2026: AI Max exits beta
AI Max for Search is generally available. All advertisers running Search campaigns can now use AI generated text guidelines. Voluntary DSA migration tools begin rolling out the same week.
April to August 2026: voluntary migration window
You can use Google's migration tools to upgrade DSA campaigns to AI Max on your own schedule. This is the recommended approach. It gives you time to test, compare performance, and adjust before the deadline.
September 2026: auto upgrade begins
All remaining DSA campaigns will be automatically upgraded to AI Max for Search. Google has not specified an exact date within September, so plan to have your migration complete by the end of August at the latest.
Your 5 step DSA to AI Max migration checklist
Whether you manage one account or fifty, these five steps will help you migrate cleanly. The goal is to preserve performance while gaining the benefits of AI Max. Do not rush this. A methodical approach beats a last minute scramble every time.
Audit your current DSA campaigns
Start with a full inventory. Document every DSA campaign and ad group: which page feeds are in use, what targeting settings are active, how much budget each campaign gets, and what the last 90 days of performance look like. Export search term reports, conversion data, and cost per acquisition numbers. This becomes your baseline for measuring AI Max performance later. If you are using page feeds with specific URL rules, pay extra attention. That level of URL control is one of the things that changes most in AI Max.
Clean up your negative keyword lists
AI Max uses broader matching logic than DSA. This means it will likely show your ads for a wider range of search queries, including some you do not want. Before you migrate, review and update your negative keyword lists. Add any brand terms, competitor names, or irrelevant categories that should be excluded. Think of this as tightening the guardrails before giving the AI more room to operate.
Test AI Max on a small subset first
Do not migrate everything at once. Pick two or three DSA campaigns that represent different use cases: one high volume campaign, one niche campaign, and one that uses page feeds heavily. Use Google's voluntary migration tool to upgrade these first. Let them run for two to four weeks before comparing results against your DSA baseline. Pay attention to cost per conversion, search term quality, and which landing pages AI Max selects. If the results are stable or improving, proceed with the next batch.
Set up AI text guidelines and guardrails
AI Max lets you define text guidelines that influence how Google generates your ad copy. Use these. Specify your brand voice, required messaging points, and any phrases that should never appear in your ads. This is not the same as writing your own ad copy, but it gives you more control than leaving everything to the AI. Also review your bidding strategies. AI Max works best with Smart Bidding, so make sure your conversion tracking is accurate before the migration.
Migrate remaining campaigns in batches
Once your test campaigns have run for at least two weeks and performance is acceptable, migrate the rest in batches of five to ten campaigns per week. This gives you time to spot problems early without putting your entire account at risk. Keep a close eye on search term reports during the first week after each batch migrates. New match types often surface unexpected queries that need to be added to your negative keyword lists.
What you lose and what you gain
Let's be honest about the tradeoffs. Platform migrations are never purely positive, and pretending otherwise does not help you plan.
What you lose
- infoGranular URL targeting. DSA page feeds let you target specific URLs and categories with precision. AI Max takes a broader approach, using its own judgment about which landing pages to serve. For multi brand portfolios or accounts with distinct product lines, this is a real loss of control.
- infoPredictable ad copy. DSA generated headlines from your site content, which kept messaging somewhat predictable. AI Max generates both headlines and descriptions using AI, so the copy may drift from your brand voice without proper text guidelines in place.
- infoHistorical reporting continuity. Google has not confirmed how long DSA historical data will be retained post migration. Export everything you need before September.
What you gain
- checkBroader reach. AI Max can match your ads to search queries that go beyond your website content. For accounts that have been limited by their site structure, this could unlock new traffic.
- checkSmarter ad customization. AI Max generates ads tailored to each individual search query, potentially improving relevance and click through rates compared to the more generic DSA approach.
- checkBetter placement reporting. As of April 2026, placement reports can now be segmented by network, giving you more visibility into where your ads are actually showing.
- checkFirst party customer list exclusions. You can now exclude specific first party customer lists from AI Max campaigns, a feature that was missing from Performance Max and that many advertisers had been requesting.
Common pitfalls to avoid during the migration
Having managed several platform migrations over the years (Smart Shopping to PMax, Enhanced CPC deprecation, broad match defaults), here are the mistakes I see most often.
Migrating everything on the last day
The September auto upgrade does not wait for you to be ready. If you migrate all your DSA campaigns in the final week, you will have no baseline to compare against and no time to fix problems. Start now.
Forgetting to export DSA data
Once the migration happens, you may lose access to historical DSA specific reporting. Download search term reports, campaign performance data, and conversion metrics for the last 6 to 12 months before you migrate.
Skipping text guidelines
AI Max will generate your ad copy. Without text guidelines, it has no guardrails. Take the time to define what your ads should and should not say. This is especially important for regulated industries and brands with strict messaging rules.
Ignoring search term quality
AI Max's broader matching means your ads will appear for queries DSA never would have triggered. Monitor search term reports weekly for the first month after migration. Add negatives aggressively. Check your optimization checklist regularly.
Monitoring performance after migration
The migration itself is only half the work. The other half is making sure performance holds up in the weeks that follow.
For the first 30 days after migrating each batch of campaigns, track these metrics daily: cost per conversion, conversion volume, search term relevance, and landing page selection accuracy. Compare everything against your pre migration baseline. Some fluctuation in the first week is normal as Google's AI learns. But if cost per conversion increases by more than 20% and stays elevated after two weeks, something needs attention.
Also watch for landing page mismatches. AI Max may send traffic to pages that are technically relevant but not optimized for conversion. If you see high traffic to pages with poor conversion rates, consider adding URL restrictions or improving those landing pages.
Tools that centralize your Google Ads monitoring can make this process significantly easier. Instead of checking each account manually every morning, a platform like aubado can flag performance changes automatically, so you know exactly which migrated campaigns need your attention. Check once a day. Stay in control. Then close the tab and do your real work.
