Microsoft Advertising Rolls Out AI Max Globally for Search Campaigns

Microsoft Advertising has begun the global rollout of AI Max, a new suite of AI-powered capabilities for Search campaigns. The update covers three key areas of optimization: expanded search term matching, automated ad text generation, and dynamic selection of landing pages.

AI Max is designed to help advertisers increase the reach of their Search campaigns, automatically adapt advertising messages to user intent, and direct traffic to the website pages that are most relevant to each search.

At the same time, Microsoft is maintaining advertiser control: AI Max is an optional feature for both new and existing campaigns.

What Is AI Max in Microsoft Advertising?

AI Max is a set of automated capabilities for Microsoft Advertising Search campaigns. It combines algorithmic reach expansion, ad message generation, and automated landing page selection.

According to Microsoft Advertising Product Liaison Navah Hopkins, the new functionality combines broader search term matching, automated ad text generation, and dynamic final URL selection.

Microsoft recommends using all three AI Max components together. However, advertisers can manage the automation through brand controls, URL rules, exclusions, and ad group-level settings.

AI Max has now begun rolling out globally across Microsoft Advertising accounts.

What Features Are Included in AI Max?

At the time of the global rollout, AI Max includes three core capabilities:

• Search term matching — expanded matching for relevant search queries;
• Text customization — automated adaptation and generation of ad copy;
• Final URL expansion — automated selection of the most relevant landing page.

Each of these features addresses a different stage of the user’s interaction with Search advertising: from identifying a relevant search query to generating an ad and selecting the page where the user will ultimately land.

Search Term Matching: Expanding Search Query Reach

The Search term matching feature allows Microsoft Advertising to go beyond the keywords that advertisers have explicitly added to their campaigns.

The algorithm can use multiple signals to determine whether a search query is relevant, including:

• keywords;
• advertisements;
• landing pages;
• user intent;
• search context;
• other available signals.

This means the system does not rely solely on a formal keyword-to-query match. Instead, it evaluates the broader context of the search.

This can be particularly relevant for complex and more conversational search queries. Microsoft also connects this functionality with the development of AI-powered search experiences, including Bing and Copilot.

For marketers, this means potentially expanding reach through queries that are more difficult to predict when building a keyword list manually.

At the same time, broader reach makes search traffic quality even more important to monitor. The more freedom the algorithm has to determine which queries are relevant, the more important search term analysis, exclusions, and conversion quality become.

Text Customization: Automated Ad Copy Adaptation

The second component of AI Max is Text customization.

Microsoft can use existing advertising assets and website content to generate additional variations of ad messaging.

The algorithm can combine available elements and determine which version of an ad is potentially the best fit for a particular search query.

Instead of requiring advertisers to manually create every possible variation of ad copy for different types of searches, AI Max takes over part of this process.

Microsoft positions the feature as a way to make advertising messages more relevant to individual users and their search intent.

This can become particularly important as AI-powered search develops and users increasingly formulate longer, more contextual queries using natural language.

For example, instead of entering a short commercial query, a user may describe their specific need in detail. AI Max is designed to adapt the advertising message to that context.

At the same time, Microsoft provides brand controls. Advertisers can use term exclusions for text asset generation, helping to prevent the system from using certain terms or phrases.

This can be important for companies with strict brand guidelines, legal requirements, or specific terminology that must not appear in advertising.

Final URL Expansion: Automated Landing Page Selection

The third component of AI Max is Final URL expansion.

Traditionally, advertisers specify the exact landing page that users reach after clicking an ad. With AI Max, Microsoft can automatically select a page from the advertiser’s website that it determines is more closely aligned with the user’s intent.

This means that the same advertising assets can potentially direct users to different pages depending on their search query.

Microsoft describes this functionality as a way to create greater consistency between three key elements:

search query → ad message → landing page.

For example, if a user searches for a specific product category, the algorithm may determine that the relevant category page is more appropriate than a general product page or the website’s homepage.

For large websites with many product categories, services, and informational pages, this can simplify landing page management.

However, marketers should still control which URLs can be used by the system. An irrelevant landing page can negatively affect not only conversion rates but also the overall user experience.

Microsoft Is Maintaining Advertiser Control

Despite the increased use of artificial intelligence, Microsoft emphasizes that AI Max does not mean advertisers are giving up full control over their campaigns.

Advertisers have access to several control mechanisms, including:

• brand controls;
• term exclusions for text asset generation;
• reporting;
• URL rules;
• ad group-level settings;
• optimization experiments.

The latter is particularly important for testing.

Marketers can test the entire AI Max suite or individual components before applying the changes more broadly.

This makes it possible to compare automated optimization with existing campaign settings and make decisions based on actual performance data.

What Will Change in Existing Campaigns?

Microsoft is also addressing advertisers who are already using automated capabilities.

If Search campaigns already use automatically generated text assets or Predictive matching, the corresponding capabilities will be moved under the AI Max framework.

The relevant AI Max settings will be enabled in affected campaigns.

However, Microsoft states that the other AI Max features will not be activated automatically.

In other words, the presence of AI Max within a campaign does not mean that all three automation capabilities will automatically be enabled at the same time.

For both new and existing campaigns, AI Max remains an opt-in feature that advertisers can activate based on their own requirements.

What Happens to Campaigns Imported From Google Ads?

AI Max also takes into account the scenario of importing campaigns from Google Ads into Microsoft Advertising.

If an eligible Search campaign is imported from Google Ads, its AI Max settings can be carried over to Microsoft Advertising.

If the original campaign already has relevant AI Max features enabled, Microsoft will preserve those corresponding settings during the import process.

For advertisers working with both Google Ads and Microsoft Advertising, this could reduce the amount of manual work required when duplicating campaigns across platforms.

However, automatic transfer of settings does not mean that campaigns can be left without further review.

Algorithm behavior, available controls, and performance can differ between the two platforms. Therefore, after importing a campaign, marketers should review its structure, search terms, ad assets, URLs, and actual performance.

An Exception for Campaigns Based on Dynamic Search Ads

Microsoft has highlighted a specific scenario involving AI Max Search campaigns that originated from upgraded Dynamic Search Ads.

When imported, these campaigns will be converted back into DSA campaigns in Microsoft Advertising.

The company says this is because it is continuing to develop additional functionality for this scenario.

For marketers who use automated campaign imports between advertising platforms, this means campaign types should be checked after migration rather than assuming that the imported structure will be identical to the original campaign.

Why Is the AI Max Launch Important for Marketers?

The launch of AI Max demonstrates the broader direction of Microsoft Advertising: Search campaigns are gradually moving away from manual management of individual elements toward comprehensive algorithmic optimization.

Previously, advertisers typically managed keywords, ad copy, and landing pages as separate components.

Now, the algorithm can participate in all three stages:

1. determining which search queries may be relevant;
2. adapting the advertising message to the query;
3. determining which website page is most appropriate for the user.

As a result, AI Max moves optimization from individual campaign elements toward the entire user journey, from the search query to the landing page.

This reflects the broader trend in performance marketing, where advertising platforms are increasingly using machine learning to determine audiences, generate advertising content, and optimize toward conversions.

What Does This Mean for Search Campaign Structure?

The expansion of AI Max may also influence how marketers structure Search campaigns.

If the algorithm has greater freedom to identify relevant search queries, advertisers may become less dependent on extremely granular manual segmentation of keywords.

However, this does not mean that campaign structure, keywords, or negative keywords are no longer important.

On the contrary, as automation increases, the quality of the inputs provided to the algorithm becomes even more important.

For AI Max to perform effectively, marketers should pay attention to:

• high-quality ad copy;
• relevant landing page content;
• a well-structured website;
• properly configured analytics;
• reliable conversion data;
• clear brand restrictions;
• regular search term analysis;
• correctly configured URL rules.

In other words, the role of the marketer is gradually shifting from manually configuring every campaign element toward controlling data quality, defining boundaries, testing automation, and evaluating business outcomes.

AI Max and the Evolution of AI-Powered Search

Another important aspect of the launch is Microsoft’s connection between AI Max and the development of AI-powered search.

Users are increasingly interacting with search engines not only through short, traditional queries but also through longer and more complex natural-language requests.

Bing and Copilot are part of this shift toward a search experience where algorithms are expected to understand not just keywords but also context and user intent.

This is why expanded search term matching and automated ad customization may become increasingly important.

For marketers, this means that successful Search advertising will increasingly depend not only on the keyword set but also on a deeper understanding of user needs, product semantics, and website content.

What Should Marketers Consider When Testing AI Max?

Before scaling AI Max, advertisers should evaluate not only overall traffic volume but also the quality of the resulting performance.

Several areas deserve particular attention.

Search queries.
Does expanded matching actually bring relevant users? Is the share of irrelevant traffic increasing?

Conversions.
An increase in clicks alone does not indicate that a campaign has improved. Target actions and their business value should remain the primary indicators.

Cost per conversion.
CPA should be compared before and after AI Max activation while also accounting for changes in traffic volume.

Ad copy.
If the system generates additional messaging variations, marketers should review whether the copy remains consistent with the brand, offer, and legal requirements.

Landing pages.
Advertisers should analyze which pages users are actually reaching and whether those pages correspond to the users’ search intent.

Data quality.
Automation cannot compensate for inaccurate conversion tracking. If an advertising platform receives incorrect or incomplete signals, the algorithm may also make suboptimal decisions.

Should You Enable AI Max Immediately?

The global rollout does not mean that AI Max should be activated across every campaign without testing.

Because Microsoft is keeping AI Max optional, advertisers can take a controlled approach: test the functionality on selected campaigns or through optimization experiments, and then compare the results.

It may be particularly appropriate to start with campaigns that already have sufficient data and clearly defined KPIs.

To evaluate the impact, marketers should establish baseline performance before activation and compare it with the results after AI Max is introduced.

Key metrics may include:

• conversions;
• CPA;
• ROAS;
• CTR;
• conversion rate;
• Search traffic volume;
• share of new search queries;
• landing page quality;
• share of irrelevant traffic.

This approach makes it possible to assess the actual impact of AI Max on business performance rather than focusing solely on technical advertising metrics.

Conclusion

Microsoft Advertising has begun the global rollout of AI Max for Search campaigns, bringing together expanded search term matching, automated ad text customization, and dynamic landing page selection within a single framework.

A key characteristic of the launch is that Microsoft is keeping AI Max optional while providing advertisers with tools to manage and control the automation.

For marketers, this is another indication that the approach to Search advertising is changing. Advertising platforms are gradually taking over more operational tasks, while the marketer’s role is shifting toward strategy, data quality management, testing, setting boundaries, and evaluating business outcomes.

AI Max also demonstrates how Search advertising is adapting to the development of AI-powered search. Rather than relying exclusively on traditional keyword matching, advertising systems are increasingly focusing on user intent, search context, and the relationship between the query, advertising message, and landing page content.

For advertisers already working with Google Ads and importing campaigns into Microsoft Advertising, the new functionality may also simplify the synchronization of certain settings. However, imported campaigns will still require review and ongoing monitoring.

The most practical approach to AI Max is not to treat it as a fully autonomous replacement for a marketer, but as an automation tool whose effectiveness should be tested, monitored, and evaluated against real business objectives.
