How to Prepare for Google’s DSA Sunset and Move to AI Max

How to Prepare for Google’s DSA Sunset and Move to AI Max

Google is retiring Dynamic Search Ads (DSA) and migrating advertisers to AI Max — a shift that changes how search campaigns are targeted, written, and routed. This article explains what’s changing, why it matters, and a practical checklist agencies and advertisers can use to move confidently before automatic migration begins in February 2027.

What AI Max changes (and why it matters)

AI Max is not just a rebrand of DSA. It combines existing signals — keywords, ad copy, budgets — with real-time intent and AI-powered text customization and final URL expansion. That makes campaigns more adaptive but also increases the need for strategic inputs, data hygiene, and active monitoring.

As Sarah Vlietstra observed in Search Engine Land: “If you’re running DSA campaigns, you have some time before you have to migrate. However, I recommend migrating before the deadline so you have control over the migration and post-migration period.” (Source: Search Engine Land)

How AI Max differs from DSA

• Targeting signals: DSA relied primarily on website crawl data. AI Max adds broader signals including keywords, ad assets, budget, and user intent.
• Creative generation: DSA constructed headlines from page copy; AI Max uses text customization to pull from multiple assets and context to write headlines and descriptions.
• Traffic routing: DSA limited routing to dynamic ad targets; AI Max’s final URL expansion can route users to any relevant page on the domain, making URL exclusions and controls critical.
• Controls: AI Max introduces Text Guidelines, brand inclusion/exclusion lists, and geographic intent controls that let advertisers steer AI behavior more precisely.

What to do now: prioritized actions

Google has extended the migration timeline after advertiser feedback. As Brandon Ervin of Google wrote: “We heard your feedback: you need more time to complete the transition from Dynamic Search Ads (DSA) to AI Max. To protect your business results and the performance of your campaigns, we are extending the timeline for Dynamic Search Ads sunset and auto-upgrade, which will begin in February 2027.” (Source: Google)

Key actions to prioritize

1. Audit and document existing DSA campaigns
   • Collect baselines (impressions, clicks, conversions, CPA/ROAS, top search terms).
   • Export dynamic ad targets and URL exclusion lists so controls are preserved.
2. Clean up conversion tracking
   • Ensure events are implemented and deduplicated; consider enhanced or server-side conversions.
3. Review and strengthen landing pages
   • Ensure pages are conversion-ready; add clear CTAs and schema where relevant.
4. Define brand and messaging guardrails
   • Use AI Max’s Text Guidelines and pre-define search term exclusions and messaging restrictions.
5. Run controlled experiments
   • Migrate a subset of campaigns and use experiments to measure lift against DSA baselines.
6. Train teams and document SOPs
   • Update processes to review AI-generated assets and monitor search term streams.

Migration checklist (practical 5-step plan)

1. Export DSA settings and performance baselines (impressions, clicks, conversions, CPA/ROAS, search terms).
2. Confirm conversion tracking quality and implement enhanced/server-side conversions where feasible.
3. Define and upload brand controls and exclusions into account Text Guidelines.
4. Migrate 10–20% of DSA spend to AI Max in a controlled experiment; monitor search terms and landing pages daily.
5. Scale in waves only after stabilizing performance and updating exclusions and asset guidelines.

Monitoring and governance

Post-migration, monitor the “Added By” column in Ads > Assets to identify AI-generated creatives. Regularly review search term reports and implement pruning routines for negatives and exclusions. Set automated alerts for sudden drops in CTR, spikes in CPA, or unexpected destination URLs and have remediation steps ready.

Conclusion

The DSA-to-AI Max migration is a strategic opportunity: with the extended runway to February 2027, advertisers can audit, experiment, and build the controls that keep AI-driven automation aligned with business goals. Early, measured migration—paired with strong measurement and clear brand guardrails—will reduce risk and unlock the potential gains AI Max promises.
