Microsoft brings AI Max to Search globally, pushing paid search beyond the keyword

Microsoft Advertising has begun rolling out AI Max for Search campaigns globally, bringing a new layer of AI-powered automation to paid search. The update allows Microsoft Ads to go beyond an advertiser’s existing keyword list, dynamically tailor ad messaging and direct users towards landing pages that better match their intent.

 At the heart of AI Max are three capabilities: search term matching, text customisation and final URL expansion. Search term matching uses signals from keywords, ads, landing pages and user intent to identify relevant searches that advertisers may not already be targeting including more complex, conversational searches taking place across Bing and Copilot.

Text customisation can generate additional messaging using existing advertising assets and website content, while final URL expansion allows Microsoft to select the landing page it believes is most relevant to an individual search.

 Importantly for advertisers, Microsoft is pairing this increased automation with controls including brand inclusions and exclusions, text-generation term exclusions and URL rules. AI Max can also be tested through optimisation experiments, allowing advertisers to assess its incremental impact rather than immediately applying the full suite across campaigns.

The development follows a wider direction across paid search, with both Microsoft and Google increasingly encouraging advertisers to give their platforms greater freedom to understand intent beyond traditional keyword targeting.

 What this means for us:

 For agencies and brands, AI Max is another indication that paid search is moving from keyword management towards intent and signal management.

 The immediate opportunity is increased reach. AI Max could help brands capture relevant demand that conventional keyword structures may miss, particularly as consumers increasingly use longer, more conversational queries and AI-powered experiences such as Copilot.

 However, greater automation makes measurement and governance more important, not less. Agencies should avoid treating AI Max as an automatic upgrade and instead establish structured tests against existing campaign approaches, assessing whether the additional reach translates into incremental conversions and commercially valuable customers.

 Landing pages and website content also become increasingly important inputs into campaign performance. If Microsoft is using these assets to understand a brand, generate messaging and determine where users should land, strong site structure, accurate content and clear product propositions increasingly become part of media optimisation itself.

 For clients already investing in Microsoft Advertising, the next step should be to identify suitable campaigns for controlled AI Max testing, establish clear performance benchmarks and review the quality of the additional search terms, creative messaging and traffic generated.

 For agencies, the bigger shift is clear: the future of search management will increasingly be about giving AI the right signals, content and guardrails, proving that the additional automation delivers genuine incremental value.
