What Is Google Replacing Dynamic Search Ads With?
Dynamic Search Ads have been a staple in Google Ads accounts for years, especially for DTC brands with large catalogs. DSA works by crawling your website or feed and automatically generating headlines and matching queries based on page content — useful for capturing long-tail demand without building out exhaustive keyword lists.
AI Max for Search is Google's replacement. Like DSA, it uses your landing page content to match ads to relevant queries. But the mechanism is different: AI Max applies large language model understanding to determine intent matches, rather than relying on crawl-based keyword extraction. It also rewrites headlines dynamically based on the specific search query — not just your existing ad copy.
The migration timeline: Google will begin automatically migrating DSA campaigns to AI Max in September 2026. Advertisers who migrate proactively before then keep more control over the transition.
Why This Matters More Than a Typical Deprecation
Most Google Ads deprecations are minor — a bid strategy renamed, a report removed. This one has real structural implications for DTC Search accounts.
A lot of brands run DSA campaigns specifically to harvest long-tail queries that their keyword campaigns miss. The strategy works: DSA finds queries you'd never think to bid on, your Search Term report fills up with useful data, and you promote the winners into exact or phrase match. That research loop breaks if AI Max doesn't surface the same query diversity.
There's also the headline rewriting question. DSA generates headlines from your page content but leaves your descriptions alone. AI Max can rewrite both headline and description components dynamically. For brands with tightly controlled messaging — think premium DTC with specific positioning language — that's a meaningful loss of control unless you configure the guardrails properly.
The key timing risk: accounts that wait for Google's automatic September migration get whatever default settings Google applies. Brands that migrate manually now can set URL exclusions, asset pinning, and query theme controls before the switch — giving AI Max better guardrails from day one.
What DTC Brands Running DSA Should Do Right Now
Before migrating, audit what your DSA campaigns are actually doing. Pull a Search Terms report from the past 90 days and identify what share of your DSA volume comes from long-tail queries you're not already capturing in your keyword campaigns. If DSA is mostly overlapping with existing keywords, the migration is low risk. If it's genuinely finding incremental traffic, you need to plan more carefully.
- Set up URL exclusions: Just like with DSA, you can exclude pages from AI Max's crawl. Make sure your checkout pages, login pages, and any thin-content pages are excluded before you migrate.
- Pin critical assets: If your brand has specific headlines or descriptions that need to appear exactly as written, pin them. AI Max will respect pinned assets and rewrite only the unpinned slots.
- Keep a keyword control campaign running alongside: Don't migrate and pause DSA without confirming AI Max is capturing the same queries. Run both in parallel for 2–3 weeks post-migration and compare search term coverage.
- Review your landing page quality: AI Max reads your landing pages the same way DSA did, but more deeply. If your product pages are thin — image-heavy with sparse copy — AI Max will have less to work with. A quick copy audit before migration can meaningfully improve match quality.
The Bigger Picture: Google Is Consolidating Around AI Max
DSA's deprecation fits a clear pattern. Google has been steadily replacing rule-based ad features with AI-driven equivalents: broad match replacing BMM, RSAs replacing ETAs, and now AI Max replacing DSA. The direction is consistent — less manual control, more algorithmic autonomy.
For DTC brands, the practical response is to invest more in the inputs Google can't touch: landing page quality, conversion tracking accuracy, and first-party audience data. Those three factors influence AI Max performance more than any campaign-level setting. Brands that get those right will extract more value from AI Max than they were from DSA. Brands that haven't will see the migration as another handover of control to Google's black box — because for them, it essentially is.
Bottom Line
The DSA sunset isn't a crisis, but it's not a non-event either. If you're running DSA as a meaningful part of your Search strategy, migrate proactively in the next 30–60 days rather than waiting for Google to do it for you in September. The brands that set up AI Max properly before the deadline will be in a much better position than those that get auto-migrated with default settings.
