# Microsoft Advertising makes AI Max the default starting point for new Search campaigns

Microsoft Advertising’s AI Max is now available across Search campaigns and enabled by default in the new-campaign flow, combining broader search-term matching, generated text and final-URL expansion while retaining brand controls, exclusions and reporting.

Microsoft’s Search automation has moved from a limited test into a default campaign-creation path. Advertisers can still switch AI Max off, but new Search campaigns now begin with a suite that can expand queries, creative and landing-page routing beyond the manually supplied keyword-and-ad structure.

## What changed

On August 27, 2026, Microsoft Advertising announced that AI Max is available to all advertisers in standard Search campaigns. The optional suite combines Search term matching, Text customization and Final URL expansion. Microsoft says the new Search campaign creation flow enables AI Max by default, although advertisers can turn it off or selectively disable individual capabilities. The platform also exposes AI-optimized labels, asset reporting and landing-page reporting, while existing negatives, budgets, targeting and brand controls continue to apply.

## Why it matters

This changes the default operating assumption for new Microsoft Search campaigns. A campaign can now move beyond the advertiser’s explicit keyword list, generate additional ad messaging from existing assets and website content, and route users to a different eligible landing page without the advertiser configuring each expansion manually. The controls remain reversible, but agencies and SaaS teams need to audit query matching, generated copy and destination behavior as first-class campaign outputs rather than assuming a new Search campaign is purely manual unless automation is explicitly added.

## AI Max expands three parts of the Search campaign at once

Search term matching uses keywords, ads, landing pages and contextual signals to find relevant searches beyond the supplied keyword list, including conversational and AI-driven queries. Text customization generates additional messaging variations from existing assets and website content. Final URL expansion can select a more relevant landing page from the advertiser’s site when Microsoft predicts it better matches the user’s intent.

## The important rollout change is the default

Microsoft describes AI Max as optional, but the new Search campaign creation flow starts with it enabled. Advertisers can turn the suite off or disable individual features, so this is not a mandatory conversion of every account. It does mean campaign-review checklists should verify the setting explicitly rather than relying on historical assumptions about what a newly created Search campaign will do.

## Microsoft is adding visibility around the automation

AI Max includes reporting intended to show where automation is contributing, including labels for AI-optimized traffic, asset-level reporting and landing-page reporting. Negative keywords, brand controls, budgets and other campaign settings continue to constrain delivery. The useful governance pattern is therefore not blanket rejection or acceptance of automation, but measuring the incremental query, creative and destination behavior it introduces.

## Vendor tests show upside, but not a universal result

Microsoft says 44 advertiser experiments produced a spend-weighted conversion uplift of about 13.6%, with ten tests reaching statistically significant positive results. Those are vendor-reported tests rather than an independent benchmark, and individual outcomes will depend on conversion quality, site structure, brand constraints and how much incremental search demand exists.

## Google Import can carry the automation across platforms

Microsoft says Google Import can bring corresponding AI Max settings into Microsoft Advertising and scheduled imports can continue inheriting them. Teams that operate both Google and Microsoft Search should therefore review import mappings and not assume an automation setting remains isolated to the platform where it was first configured.

## Key details

- Microsoft announced broad AI Max availability for Search campaigns on August 27, 2026.
- AI Max combines Search term matching, Text customization and Final URL expansion.
- The new Search campaign creation flow enables AI Max by default, but advertisers can turn it off or disable individual capabilities.
- Search term matching can reach relevant searches beyond the explicit keyword list.
- Text customization can generate additional ad messaging from existing assets and website content.
- Final URL expansion can route traffic to an eligible landing page Microsoft considers more relevant.
- Negative keywords, brand controls, budgets and existing targeting settings remain available.
- Microsoft provides AI-optimized labels, asset reporting and landing-page reporting.
- Microsoft’s reported experiment results are vendor-produced and should be validated at account level.

## Builder takeaways

- Add AI Max state to every new Microsoft Search campaign QA checklist; default-on is different from mandatory, but it is easy to overlook.
- Review search-term reports for incremental queries and exclude irrelevant themes rather than judging the feature only from aggregate conversions.
- Audit generated text and final landing-page destinations for brand, compliance and funnel consistency before scaling spend.
- Keep clean conversion tracking and value signals in place because broader matching is only useful when the bidding and measurement system can distinguish valuable outcomes.
- If you use Google Import, document which automation settings are expected to transfer so a cross-platform import does not silently broaden matching or creative behavior.
- Run a controlled comparison against your existing Search setup and evaluate conversion quality, CPA/ROAS, query mix and landing-page distribution rather than relying on Microsoft’s aggregate uplift claim.

## What to watch

- Whether Microsoft changes the default-on behavior after broad adoption data accumulates.
- Independent advertiser evidence on conversion quality and query expansion, not just conversion volume.
- API and Editor controls for creating, auditing and disabling the individual AI Max components.
- How closely Microsoft’s AI Max import mappings track Google Ads as either platform changes its Search automation model.
- Whether AI Max becomes the migration target for older Microsoft Search campaign features in the same way Google is consolidating controls into its own AI Max.

## Uncertainties

- Microsoft’s 13.6% spend-weighted conversion uplift is based on its own advertiser experiments and does not establish a typical account result.
- The Help documentation and rollout announcement can lag each other during broad deployment, so some account surfaces may appear at slightly different times.
- Expanded matching and destination selection can improve scale while also changing traffic quality; the net effect depends on each advertiser’s data and site structure.
