Why Every Optometry Account Running DSA, ACA, or Broad Match Is on a Countdown Clock

The September 2026 migration is non-optional for accounts running the affected campaign types. Dynamic Search Ads, automatically created assets, and campaign-level broad match all auto-migrate into AI Max regardless of whether the practice has prepared. The deadline is not an upgrade choice; it is a platform-level transition Google has scheduled, and the only operator-controlled variable is whether the migration happens by deliberate plan or by default.

OD accounts often carry DSA campaigns built years ago for routine-exam volume that nobody has reviewed in months. The same accounts often run automatically created assets without explicit guidelines, and many run campaign-level broad match on insurance-network and convenience-modifier queries. Each of these is a migration trigger, and each will arrive in September with whatever Google’s auto-migration defaults configure if nothing changes between now and then.

The voluntary-migration window matters because the auto-migration removes two operational choices. First, the ability to capture a clean pre-migration performance baseline. Second, the ability to selectively decline individual AI Max features that introduce HIPAA or tracking risk for the OD account. The practice that migrates voluntarily retains both. The practice that defers loses both at the September deadline.

How AI Max Sits Between Traditional Search and Performance Max in Control

AI Max is not a new campaign type. It is a three-feature suite that sits inside existing Search campaigns. Search term matching expands query coverage beyond keyword text into broad and keywordless interpretation. Text customization lets Google generate ad headlines and descriptions adapted to specific queries. Final URL expansion (FUE) substitutes advertiser-provided URLs with dynamic landing pages selected from Google’s analysis of the site.

The structural position is between traditional Search and Performance Max in terms of control and automation. Traditional Search keeps keywords, ad copy, and landing-page routing under explicit advertiser control. PMax surrenders most of those decisions to Google’s optimization. AI Max keeps the campaign-level frame of Search but moves the three feature-specific decisions toward automation. The advertiser sets guardrails (brand restrictions, location controls, text guidelines, allowed-URL lists) and Google operates within them.

The control surface for AI Max is the guardrail configuration. An account that activates the three features without configuring the guardrails effectively runs PMax-level automation inside a Search campaign frame. An account that activates the features with tight guardrails configured retains meaningful control while capturing the lift Google reports for the feature suite.

The HIPAA dimension matters most for OD accounts because final URL expansion is the feature that introduces the highest compliance risk. Without URL controls, FUE can route searchers to condition-specific pages (dry eye, myopia, VT, pediatric) that the practice did not intend to serve through ad routing. The HIPAA-safe configuration is in setting up AI Max without sabotaging HIPAA compliance, which is required reading for any OD account preparing the migration.

Google’s Reported Lift Numbers and the Brainlabs 40 Percent Combined Activation

Google reports approximately 14 percent more conversions at similar CPA or ROAS for typical AI Max activation, with about 27 percent for accounts heavily weighted toward exact and phrase match keywords (Google Ads Help, internal data, 2025). The full-suite lift over search term matching alone is about 7 percent incremental (blog.google, April 2026). The numbers anchor the upper end of what well-configured AI Max activation should produce; OD accounts should expect to land toward the middle of the range rather than at the headline figure.

Brainlabs reported a 40 percent higher success rate when all three AI Max features are enabled together compared to baseline (PPC Live, April 2026). The combined-activation lift is meaningful but the success-rate framing is not directly comparable to conversion-volume metrics. The Brainlabs case is a directional signal that the features compound rather than cancel, not a guarantee that any specific account will see the same combined-feature effect.

For benchmark context on how the AI Max lift numbers compare against OD-specific CPA and CVR anchors, see optometry PPC benchmarks. The benchmark frame matters because the AI Max lift only outperforms when the post-migration performance meets the OD-specific target ranges rather than the broader healthcare averages that the platform’s lift numbers reference.

Five Red Flags That Your OD Account Has No Pre-Migration Plan

Five conditions that indicate the OD account is heading into the September 2026 deadline without preparation.

DSA campaigns still running with no migration plan. The legacy DSA campaigns will auto-migrate in September if nothing changes. Accounts without a documented migration plan inherit whatever default AI Max configuration Google applies, which removes the practice’s ability to opt out of specific features.

Final URL expansion enabled on condition-specific pages. The HIPAA-risk surface for OD accounts. With dry eye, myopia, vision therapy, and pediatric pages in the sitemap, FUE without URL controls can route searchers to condition-tagged pages, which creates the compliance exposure the practice almost certainly did not intend.

No brand restrictions configured. AI Max text customization can generate ad copy referencing competitor brands or off-strategy phrasing without explicit brand-restriction guardrails. The configuration step is small but the brand-control implications are meaningful.

No pre-migration performance baseline captured. The account has not snapshotted current campaign performance against which post-migration performance will be compared. Without the baseline, the migration’s actual impact cannot be measured cleanly, which gives the agency room to attribute either gains or losses to migration without empirical anchoring.

Tracking templates not validated against dynamic landing pages. Final URL expansion routes traffic to URLs other than the advertiser-specified destination. If the tracking templates assume the original URL structure, the post-migration tracking can break in ways that surface as conversion-volume gaps in the data the agency reports back. The structural pattern parallels the broader data-quality discipline in good Google Ads management for optometry.

How to Migrate Voluntarily Before September with Brand Restrictions and Tracking Validation

The pre-September preparation runs across five steps and takes about 8 to 16 hours of campaign and tracking work for a typical OD account.

Within the next 15 minutes, inventory the campaigns running DSA, ACA, or campaign-level broad match. Each is a migration trigger and each needs explicit pre-September preparation. The inventory is the starting point for the migration plan.

Migrate voluntarily to retain control of the feature mix. Voluntary migration lets the practice activate AI Max features one at a time rather than accepting whatever default the auto-migration applies. Search term matching is generally a reasonable first activation; text customization and final URL expansion warrant tighter pre-activation review for OD accounts.

Capture a 30-day baseline of current performance before the migration goes live. CPA, CVR, conversion volume, impression share, and per-campaign performance distribution all need pre-migration snapshots. The baseline is what defines whether post-migration performance is better, worse, or flat. Without it, the comparison is anecdotal rather than quantitative.

Configure brand restrictions, location controls, and text guidelines explicitly. The guardrail configuration determines how much control the practice retains over text customization output. Validate tracking templates against final URL expansion if FUE is being activated, and tighten the negative keyword list to prevent search term matching from expanding into queries the practice cannot serve. Pair the migration with the broader compliance setup in AI Max HIPAA compliance if condition-specific pages exist in the OD site.

Why the Migration Is Not Optional but the Feature Mix Still Is

Our view is direct. The September migration is not optional, but the specific AI Max feature mix is. Eye care practices should turn on search term matching, carefully test text customization, and default OFF on final URL expansion until HIPAA-safe landing-page governance is proven. The feature mix is the operator-controlled variable, and the configuration choices made before September determine how much control the practice retains afterward.

The accounts that prepare voluntarily capture the lift Google reports while controlling the compliance and tracking risks the auto-migration would otherwise introduce by default. The accounts that defer accept whatever defaults Google applies in September, which forecloses the operational choices that the voluntary window preserves.
