Microsoft's opt-in AI suite for Search campaigns — expanded query matching, AI-written ad text, and smarter landing-page routing — aimed at conversational searches on Bing and Copilot. Rolling out globally from August 2026.

Microsoft Advertising AI Max for Search is an opt-in set of AI features that layer onto your existing Microsoft Search campaigns — not a new campaign type. Microsoft announced it on April 21, 2026, opened an open pilot in May, and began rolling it out to advertisers worldwide in August 2026. It is Microsoft's counterpart to Google's AI Max for Search, and importing a Google Search campaign that already has AI Max enabled turns on the matching Microsoft settings.
AI Max bundles three things. Expanded query matching (search term matching) reaches relevant searches beyond your keyword list, using signals from your keywords, ads, landing pages, and searcher intent — Microsoft's pitch is that this catches the longer, more conversational questions people ask on Bing and on AI surfaces like Copilot Search and Copilot Answers. Text customization writes additional ad copy from your existing assets and website content. Final URL expansion can send a click to a more relevant landing page than the one on the ad.
You keep guardrails: brand inclusions and exclusions, term exclusions for text generation, URL rules that limit where final URL expansion can point, ad-group-level settings, and search-term plus asset reporting from the start. Microsoft is also folding its earlier Predictive matching and autogenerated text assets features under AI Max — campaigns already using either have the corresponding setting switched on automatically.
The important thing to be clear about: AI Max is an ad-buying optimizer, not a content generator. It remixes and matches the assets, copy, and landing pages you already have; it does not build a brand's video, carousels, blog, or the pages it reads. Microsoft has cited pilot gains — early recaps mention roughly a 5% lift in click-through rate from AI-optimized text and about 8% incremental conversions — as pilot averages, not guarantees; confirm current specifics in the platform.
AI Max only ever works with material you already own. Its text customization remixes your headlines and descriptions, and it reads your landing pages and website to write ads and choose a destination — so its output is capped by the quality and breadth of the content you feed it. It cannot manufacture an on-brand content library, and it cannot write the pages it personalizes from. That is the exact job [Kompozy](/) does, which makes the two fit together cleanly: Kompozy produces the raw material, AI Max distributes and optimizes the paid slice of it.
Concretely, use Kompozy to generate the assets AI Max feeds on. From one source, Kompozy writes governed blog articles and long-form posts that become the landing-page and website content AI Max reads to craft better ad text and pick better final URLs — all held to your [Persona Brief](/glossary/persona-brief) so the automated ad copy inherits a consistent voice. In parallel, Kompozy answers those same conversational Bing-and-Copilot questions organically: captioned [Persona Shorts](/glossary/persona-shorts), brand-exact [Carousels](/glossary/hyperframes), quote graphics, text posts, and newsletters, auto-reframed and published across the eight social platforms plus blog and email, or on [Autopilot](/glossary/autopilot). AI Max rents attention per click; Kompozy builds the owned content and audience that make each click cheaper and warmer.
No. AI Max is an ad-buying optimizer for Microsoft Search campaigns. It matches queries, writes ad-text variations from your existing assets, and routes clicks to better landing pages — but it does not generate a brand's video, carousels, blog, or the pages it reads. Producing that content is a separate job handled by a content engine like Kompozy.
It adds three opt-in behaviors: expanded query matching that reaches relevant searches beyond your keyword list, AI text customization that writes extra ad copy from your assets and website, and final URL expansion that can pick a more relevant landing page. You keep brand and term controls, URL rules, and search-term plus asset reporting.
Microsoft announced AI Max on April 21, 2026, opened an open pilot in May, and began a global rollout to advertisers in August 2026 as it moved into general availability. Rollout timing can vary by market, so check your own Microsoft Advertising account.
AI Max is built to reach the longer, more conversational questions people ask on Bing and on AI surfaces like Copilot Search and Copilot Answers. Its expanded query matching uses signals from your keywords, ads, landing pages, and intent to appear for those searches, rather than only exact keyword matches.
Yes, and they complement each other. Kompozy generates the branded blog, landing content, and social posts; AI Max reads those pages and assets to write better ads and capture paid demand on Bing and Copilot. Kompozy builds the owned organic reach; AI Max rents the high-intent paid slice.
