Quick answer: If you manage Google Search campaigns, September 2026 deserves a deliberate account review. Google says campaigns using the campaign-level broad match setting or text customization (previously called automatically created assets) will begin upgrading automatically to AI Max for Search campaigns this month.
The short answer: don't treat this as a routine label change. Before it lands in your account, confirm your conversion goals, eligible landing pages, generated text, brand and location controls, negatives, and reporting baseline. AI Max can expand matching, customize ad text, and send users to different pages on your domain — weak tracking or an untidy website can hand it poor instructions.
This isn't a reason to panic or switch everything off. It's a reason to know exactly what's enabled and what success should look like.
Key Dates to Know
- September 2026: Search campaigns using campaign-level broad match or text customization begin auto-upgrading to AI Max.
- February 2027: Dynamic Search Ads follow a separate, later timetable for their automatic AI Max upgrade.
- Account Variability: Eligibility and exact timing vary by account — check the notification inside your own Google Ads account rather than assuming a fixed date.
What's Actually Changing?
AI Max isn't a new campaign type — it's an optimization layer inside your existing Search campaigns, built from three capabilities:
- Search term matching: Broadens the queries that can trigger your ads, learning from your keywords, creative assets, and landing pages.
- Text customization: Can generate additional headlines and descriptions from your website, existing ads, and keywords.
- Final URL expansion: Can send users to a different, relevant page on your domain instead of the one you chose.
For setup and dependency details, see Google's AI Max setup documentation, broad match setting guidance, and text customization guidance.
AI Max vs. Search vs. Performance Max
| Campaign Type | Inventory | What It Is |
|---|---|---|
| Search (no AI Max) | Search only | Conventional campaign, advertiser keywords, manual inputs |
| Search + AI Max | Search only | Automation layer adding expanded matching, site signals, optional asset optimization |
| Performance Max | Search, YouTube, Display, Discover, Gmail, Maps, etc. | Separate, goal-led campaign type across channels |
AI Max doesn't make Performance Max redundant, and Performance Max isn't just "a stronger AI Max." Campaign choice should follow the business objective, creative supply, tracking quality, and how much channel-level control you need, not the newest label.
The 10-Point AI Max Upgrade Checklist
-
Step 1: Confirm Which Campaigns Are Affected
Open each active Search campaign → Settings → AI Max. Record whether search term matching, text customization, and Final URL expansion are enabled; don't assume every campaign migrates on the same day. Log the objective, bid strategy, budget, AI Max status, and migration date for later reference.
-
Step 2: Clean Up Conversion Tracking Before Reach Expands
Automation optimizes toward whatever you've labeled a conversion. If newsletter sign-ups, page views, and qualified leads all count as equally important, AI Max may chase the easiest action rather than the most valuable customer. Review primary vs. secondary actions, duplicate tags, lead quality, and values; connect qualified-lead stages where consent and systems allow. Don't judge the migration on clicks alone.
-
Step 3: Export a Clean Pre-Upgrade Baseline
Save at least four weeks of data (longer for low-volume or seasonal accounts): spend, conversion rate, conversion value, cost per qualified conversion, and search-term mix. Annotate promotions, outages, and landing-page edits — a week-over-week comparison is misleading if one period contains a sale.
-
Step 4: Decide Which Pages May Receive Paid Traffic
Final URL expansion is only as good as your domain. Audit for pages that should never be an ad destination: careers, policies, login screens, expired offers, thin posts, sold-out products, unserved locations. Add URL exclusions accordingly. Final URL expansion is on by default with AI Max and depends on text customization; review how it works before changing either setting.
-
Step 5: Make the Remaining Landing Pages Automation-Ready
AI Max reads your website as an input, so a vague page weakens both targeting and generated messaging. Each eligible page should state the offer, audience, availability, differentiator, and next action — with accurate prices, stock, and dates. Check mobile usability, speed, and form completion. Automation doesn't repair a poor landing experience.
-
Step 6: Review Generated Text for Accuracy and Brand Safety
Text customization can assemble headlines and descriptions from your domain and existing campaigns. Check asset reports for items marked "Google AI" and remove anything inaccurate, off-brand, or legally sensitive. Note: pinned responsive-search-ad assets may not serve when a different Final URL is selected — where pinning matters for compliance, that control may outweigh the benefit of expansion.
-
Step 7: Set Brand and Geographic Guardrails
Use the brand inclusion/exclusion and location-of-interest controls at the campaign or ad-group level. A local provider should distinguish physical presence from interest in a location, per its operating model. Recheck brand lists, language, radius, and excluded locations after migration.
-
Step 8: Watch Search Terms, Not Just Headline Totals
More traffic isn't automatically better traffic. Review the actual query, the headline shown, and the landing page selected together. Watch for research queries, job seekers, support requests, or off-topic matches eating budget. Add negatives for clearly irrelevant patterns, but give it at least two weeks of learning before broad optimization changes — intervene sooner only for a real brand, compliance, or budget risk.
-
Step 9: Protect the Test From Budget and Bidding Noise
Don't flip on AI Max, change bid strategy, double budget, and swap every ad in the same afternoon — you won't know which change drove the result. Keep the real business target visible (cost per qualified lead, profitable ROAS, booked revenue), and extend the observation window if volume is limited.
-
Step 10: Use a Scheduled Review Rhythm
Review more often in month one, without editing impulsively:
- Day 0: Save settings and baseline; log the migration date.
- Days 1–3: Check tracking, policy status, spend pace, obviously unsuitable URLs.
- End of Week 1: Inspect early search themes, assets, landing pages.
- After Week 2: Make evidence-based negatives, exclusions, or creative changes.
- End of Week 4: Compare qualified outcomes to baseline and seasonality.
Where available, a controlled experiment beats a blanket rollout. Google's own launch data reported positive average results — but an average isn't a forecast for your account. Your tracking and unit economics decide whether it's working.
Already Been Upgraded? You Haven't Missed the Review
Open the campaign's AI Max settings and check each component individually, not just the master toggle:
- Search terms and the pages users reached
- Google-created assets and their claims
- URL inclusions and exclusions
- Brand and geographic settings
- Conversion actions, values, and lead quality
- Spend pace vs. your pre-upgrade baseline
Google allows individual AI Max features to be modified or disabled. The right response is neither "leave everything on" nor "turn everything off" — keep what's surfacing relevant demand and add guardrails wherever automation is making poor choices.
The Practical Decision Rule
AI Max tends to help when conversion data is trustworthy, landing pages are well organized, ad groups reflect genuine intent, and someone actually reviews the reports. It gets riskier when the account optimizes toward weak actions, the website has outdated pages, or no one checks generated claims and destinations.
The technology changes the manager's job — it doesn't remove it. Less time goes into exhaustive keyword lists; more time goes into measurement design, landing-page quality, exclusions, creative accuracy, and commercial judgment.
Turn the Upgrade Into a Controlled Test
September's migration is a useful trigger to audit more than one toggle. The real question: is Google receiving reliable conversion signals and accurate website content, are the boundaries clear, and can you measure the quality of the customers it attracts?

Frequently Asked Questions
A: No. AI Max is an optimization layer inside Search campaigns. Performance Max is a separate, goal-based campaign type that can serve across multiple Google inventories.
A: Not simply by enabling AI Max — but campaigns migrating from the campaign-level broad match setting have specific keyword-prioritization considerations. Save your current structure and read Google's broad-match migration guidance first.
A: Google allows individual features to be adjusted, but Final URL expansion depends on text customization — review that relationship before disabling either one.
A: Budget size alone doesn't decide it. Smaller accounts need especially clean tracking, focused geography, disciplined exclusions, and enough time to gather real evidence — don't expand targeting just because the interface recommends it.
A: The search terms report, the "Search terms and landing pages from AI Max" view, keyword report, asset reports, and landing-pages report. Google-created text assets are labeled in reporting so you can review and remove unsuitable ones.
