Google is retiring Dynamic Search Ads and migrating eligible campaigns to AI Max for Search starting in September 2026. Service businesses running DSA need to plan the migration now — here's what changes and how to prepare.

Google confirmed in April 2026 that it is retiring Dynamic Search Ads (DSA) and automatically migrating eligible campaigns to AI Max for Search starting in September 2026. The new AI Max text guidelines became universally available in April after months in beta.
For service businesses that rely on DSA — and many do, often without realizing it is a separate campaign type — this is a forced migration. Going through it intentionally now will produce better outcomes than going through it automatically in September. Here is what changes, what to prepare, and how to migrate.
Dynamic Search Ads automatically generated headlines and selected landing pages based on the content of your website. You provided the URL, Google figured out the queries to target and the headlines to write. For service businesses with deep service catalogs (long lists of services across many locations), DSA was often the workhorse that captured long-tail demand without requiring you to build out manual keyword lists.
The downsides of DSA were real: limited control over messaging, occasional irrelevant matches, harder reporting, and a tendency to consume budget on queries that did not convert well.
AI Max for Search is the spiritual successor to DSA, with significant capability upgrades:
1. Stronger query understanding. AI Max uses the latest Google AI models to interpret search intent, surfacing your ads on conversational queries that DSA would have missed.
2. AI-generated text customization. Headlines and descriptions adapt to the specific query in real time, within the brand and messaging guardrails you set.
3. Better landing page selection. Instead of just matching keyword to URL, AI Max routes users to the page most likely to convert based on intent signals.
4. Tighter integration with Google's other AI products. AI Max campaigns interact with Performance Max, AI-driven bidding, and the broader Google Ads optimization layer in ways DSA did not.
The trade-off is the same as it was with DSA: you give up a degree of control in exchange for AI-driven scale. The new layer of guardrails (brand tone, messaging requirements, exclusion lists) gives you back some of that control without requiring you to micromanage.
Three reasons:
1. Manual migration produces better results than automatic migration. When Google migrates your DSA campaigns automatically in September, it will use default settings. The defaults are reasonable but not optimal for your specific business. Migrating manually now lets you set the brand tone, messaging requirements, exclusion lists, and bid strategies that fit your business — before the system has months of suboptimal data baked in.
2. The learning period takes time. AI Max campaigns need 4-8 weeks of data to fully optimize. Migrating now means by September your campaigns are tuned and performing. Migrating in September means you are entering Q4 — your biggest revenue quarter for many service businesses — with campaigns that are still learning.
3. You can run AI Max alongside DSA during the migration. This lets you A/B compare performance, identify the messaging guardrails that work for your business, and migrate confidently rather than reactively.
For a service business with active DSA campaigns, here is the recommended sequence:
Pull a 90-day report on your DSA campaigns. Note:
This data is your migration map.
In Google Ads, create a new AI Max for Search campaign. Configure:
Allocate 25% of your DSA budget to the AI Max campaign. Let it run for 30 days alongside DSA.
After 30 days, compare conversion rate, cost per conversion, and lead quality between AI Max and DSA. Tune the AI Max campaign:
As AI Max performance stabilizes and meets or exceeds DSA, shift budget progressively. By August, you should be at 100% AI Max with DSA fully retired on your own schedule rather than Google's.
Three patterns that show up in service-business AI Max migrations:
1. Initial cost-per-conversion spike. AI Max often costs more per conversion in the first 2-3 weeks while it is learning. This is normal. Do not kill the campaign early.
2. Different conversion volume distribution. AI Max tends to win on long-tail conversational queries that DSA missed. Your conversion volume may go up while your top queries shift. The mix is usually healthier; the headline numbers may look different.
3. Increased need for landing page quality. AI Max routes users to the most relevant page. If your service pages are weak (thin content, no clear CTA, slow load), AI Max will drive lower conversion than DSA did. Audit your top landing pages before migrating to make sure they are converting at acceptable rates.
Three mistakes that cost service businesses money in early AI Max migrations:
1. Over-restricting messaging guardrails. Setting too many required phrases and tone constraints handcuffs the AI. Start with light guardrails and tighten as you see what generates off-brand outputs.
2. Migrating all campaigns at once. Migrate the lowest-stakes campaigns first. Build experience. Then migrate the high-stakes ones. Migrating everything in one week guarantees you will have at least one campaign performing badly without an obvious reason.
3. Not updating landing pages. AI Max routes users to the best-converting page based on intent. If you have not updated your landing pages in 12 months, the routing intelligence is wasted on weak destinations. Refresh your top 5-10 landing pages as part of the migration.
The DSA-to-AI Max migration is part of a larger shift across Google Ads in 2026. Performance Max, AI Max for Search, AI Max for Shopping, and AI-driven bidding are converging into a single AI-managed campaign architecture. Service businesses running ads in 2027 will manage portfolios of AI campaigns rather than managing individual ad groups and keywords.
The skill set for managing Google Ads is changing accordingly. Less time spent in the keyword editor. More time spent shaping the brand and messaging guardrails the AI operates within. More time spent ensuring your landing pages and conversion tracking are healthy enough for AI optimization to work on top of.
The DSA retirement is a forcing function for that transition. Services that get good at it now will outperform competitors who wait until the migration is forced on them.
Why migrate from Dynamic Search Ads to AI Max manually instead of waiting for Google's automatic September migration?
Manual migration lets you set messaging guardrails, brand tone, exclusion lists, and bid strategies that fit your business — before months of suboptimal default-setting data bake in. Manual migration also runs AI Max alongside DSA for comparison data and avoids entering Q4 (typically the biggest revenue quarter) with campaigns still in their learning period.
How long does AI Max take to fully optimize after launching?
4-8 weeks of consistent budget and conversion data. The first 2-3 weeks often show higher cost-per-conversion as the AI learns. This is normal — do not kill the campaign early. By week 6-8, performance typically stabilizes at or above what DSA was producing.
What's the most common mistake during DSA-to-AI Max migration?
Three mistakes show up repeatedly: over-restricting messaging guardrails (handcuffs the AI), migrating all campaigns at once (guarantees one will perform badly without obvious reason), and not updating landing pages (AI Max routes to best-converting page, which means weak pages waste the routing intelligence).
Will AI Max work better than DSA for my service business?
For most service businesses, yes — particularly on long-tail conversational queries that DSA missed. AI Max tends to win on volume of relevant conversions and lose slightly on cost predictability. The net is usually positive, but the right answer depends on your specific account. The 30-day pilot tells you.
