Google Retiring DSA in September 2026: Ecommerce Seller Migration Guide to AI Max
What DSA Retirement Actually Means
Dynamic Search Ads launched in 2010 as Google’s answer to a common problem: keyword-based campaigns inevitably miss long-tail queries. DSA solved this by crawling your website and automatically matching ads to relevant search queries you had not explicitly targeted. For ecommerce sellers with large catalogs, it became a reliable catch-all for traffic that manual keyword management would overlook.
AI Max for Search replaces DSA entirely. The shift is more fundamental than a name change. AI Max does not use keyword targeting at all. Instead, it analyzes your ad copy and landing page content to determine which search queries your ads should match against.
DSA still left you some control levers. You could specify which URLs to target, exclude pages from crawling, and filter by categories. AI Max strips most of these away. According to Google’s official blog post on the DSA to AI Max upgrade, the system automatically decides who sees your ads, which creative serves, and when to bid.
The migration is automatic. Eligible DSA campaigns will be converted to AI Max without any action required from advertisers. There is no opt-in prompt, no confirmation dialog. If your DSA campaign meets the migration criteria, it becomes an AI Max campaign on Google’s schedule.
For cross-border sellers, this means your account structure will change in material ways. Many sellers organize DSA campaigns by product category, by market, or by language. Auto-migration may flatten or merge these structures. Campaign strategies you spent months refining may no longer apply after the transition.
Why Google Is Making This Change
AI Max is not a standalone product tweak. It is part of Google’s broader push toward AI-driven advertising across all channels. Performance Max has already validated this approach over the past two years: advertisers provide creative assets and conversion goals, and Google’s algorithms handle targeting, bidding, and placement. The results in several ecommerce verticals have outperformed traditional manual campaigns.
Now Google is applying that same model to Search, its largest revenue stream and the channel where advertisers have historically maintained the most control. DSA was a stepping stone — it automated the matching process but kept the keyword framework intact. AI Max skips keywords entirely and infers user intent directly from ad copy and landing page signals.
Google’s stated rationale is that AI Max delivers better performance because it is not limited by the keywords advertisers choose. In practice, many sellers do maintain outdated keyword lists. Product lines change, categories expand, but keyword sets rarely get updated with the same frequency. AI Max removes that maintenance burden.
Competitive pressure also plays a role. Meta’s Advantage+ Shopping Campaigns have demonstrated strong results in ecommerce by automating audience selection and bidding. Google needs an equivalent AI-first solution for Search to prevent advertising budgets from continuing to shift toward Meta’s platform.
This change also reflects Google’s confidence in its own AI capabilities. From search ranking to shopping recommendations, Google’s models have accumulated enough signal data to support keyword-less advertising. For smaller sellers, this could be a net positive — you do not need a dedicated optimization specialist to get decent results. For larger sellers, the reduced control means less room for granular optimization.
Key Differences Between AI Max and DSA
| Dimension | DSA | AI Max for Search |
|---|---|---|
| Targeting method | Crawls website to match search queries | AI analyzes ad copy + landing page to match search intent |
| Keyword control | No manual keywords, but negative keywords available | No keyword concept at all, negative keyword capability significantly reduced |
| Ad copy control | Dynamic headlines generated from page content, custom descriptions allowed | Requires 10-15 headlines and 5-8 descriptions, AI composes combinations |
| URL targeting | Specify target URLs or exclude pages | AI selects URLs automatically, control granularity reduced |
| Reporting granularity | Full search term-level reports | Aggregated reporting, search term detail reduced |
| Learning period | No learning period, runs immediately | 1-2 weeks learning phase with unstable performance |
| Conversion data requirement | No minimum conversion volume required | Requires consistent conversion data; new or low-volume accounts perform poorly |
| Budget allocation | Per-campaign independent control | AI distributes budget across signals, spending flow less transparent |
The practical takeaway: DSA took away keyword selection but left you control over landing pages, negative keywords, and URL targeting. AI Max narrows those intervention points further and hands more decisions to the algorithm.
The upside is less hands-on management. You stop mining for new keywords, tweaking match types, and maintaining negative keyword lists. The downside is that your effort must shift elsewhere — ad copy quality, landing page content, and conversion data accuracy become the new optimization levers.
One more thing worth noting: DSA reporting is at the search term level, so you can see exactly which queries drove clicks and conversions. AI Max reporting is more aggregated, meaning you lose the ability to do fine-grained “this term works, that term does not” analysis. Your optimization mindset needs to shift from tuning keywords to tuning creative assets.
Migration Checklist for Cross-Border Sellers
Start by auditing your existing DSA campaigns. Count how many you have, note the daily budget for each, and record the ROAS and conversion volume over the past 90 days. This data is your baseline for comparing AI Max performance after migration. Without it, you have no way to measure whether the migration helped or hurt.
Audit every landing page that your DSA campaigns point to. AI Max reads page content to determine matching, so thin pages with sparse product descriptions or machine-translated copy will produce poor matches. Cross-border sellers face a specific risk here: if you target English-speaking markets but your landing pages are written in broken English or rely on auto-translation, AI Max will not match your ads effectively.
Prepare your ad creative. AI Max requires a minimum of 10-15 headlines and 5-8 descriptions, which the system combines automatically. Create separate sets for each target language — do not rely on Google’s automatic translation. Headlines should cover core product benefits, price advantages, and trust signals. Descriptions should be specific to features and use cases.
Verify your conversion tracking is accurate. AI Max depends heavily on conversion data for optimization. If your tracking is missing orders, double-counting, or not installed at all, the model will learn from corrupted data. Cross-check your Google Ads conversion actions against Google Analytics 4 or your Shopify backend to ensure numbers align.
Check your product feed data quality. If your DSA campaigns interact with Shopping campaigns, the feed data — titles, descriptions, images, pricing, availability — must be current and accurate. AI Max incorporates feed signals into its matching logic, so stale or incomplete feed data will degrade performance. Feed quality matters not just for Shopping ads but for how AI Max understands your products.
Monitor closely for the first two weeks after migration. Watch the search terms report to see if queries are relevant to your products, check whether conversion rates have dropped significantly, and look for abnormal CPC increases. If data remains poor after two weeks, consider creating a new AI Max campaign to take manual control rather than relying on the auto-migrated version.
Prepare a backup plan. Auto-migration does not guarantee optimal migration. Sellers with complex DSA structures — multiple ad groups organized by category, for example — may find the auto-migrated version flattened into a single AI Max campaign, losing the structural advantages they had built. Know in advance whether you will rebuild manually or reallocate budget if auto-migration underperforms.
A Reality Check
Auto-migration means losing control overnight. Your daily optimization work shifts from managing keywords to managing creative assets and landing pages. The nature of the work changes, not the workload.
For cross-border sellers, the most critical vulnerability is landing page content quality. Many independent sites have English product pages that are machine-translated, with awkward phrasing and unclear value propositions. Under DSA, Google’s crawler primarily focused on page structure and keyword density, so poor translation could sometimes be offset by technical optimization. AI Max actually reads your page content semantically — pages with broken language will be flagged as low-quality matches and receive fewer impressions.
This is now a content quality game, not a keyword optimization game. Sellers with well-written pages, rich creative assets, and clean conversion data will perform well in AI Max. Sellers with thin pages, sparse assets, and messy data will be deprioritized by the algorithm. The keyword playbook no longer applies.
On budget: do not panic-spend during the learning period. AI Max is inherently unstable in the first few days, and poor early data is normal. Give it at least two weeks before making a judgment. Conversely, if performance improves quickly, do not immediately increase budget significantly — AI Max’s learning model needs to recalibrate when budget changes sharply. Keeping budget stable during the learning phase is the optimal strategy.
There is another often-overlooked point: if you advertise in multiple language markets, each market’s AI Max model learns independently. Strong performance in English does not guarantee the same results in German or Japanese. Each market requires separate creative preparation and quality monitoring — one creative set does not work across all markets.
