Search is entering its most transformative era to date. As AI reshapes how people discover, evaluate, and choose brands, the foundations of traditional paid search; static keyword lists, rigid structures, and manual controls, are no longer fit for purpose. At Assembly, we believe AI Max is not just another campaign type; it represents the future of Search Ads.
Over the past year, we have tested, mastered, and scaled AI Max across global clients and verticals. In doing so, we have not simply adopted a new product – we have redefined how it works best, working in close partnership with Google teams to shape best practice and inform the roadmap. Today, we are operating from a position few advertisers have reached: Search accounts built deliberately on Exact Match and AI Max only, without reliance on Broad Match as a safety net.
This matters because AI Max signals a fundamental shift: from keyword management to signal orchestration; from static coverage to adaptive demand capture; from reactive optimisation to system design. This mirrors the system‑level thinking that underpins how we design and scale Search+ across AI‑driven Search experiences.
Most advertisers are still approaching AI Max tactically or cautiously. We take a fundamentally different view: AI Max works when it is demand-led, structurally simplified and effectively governed as part of a wider Search system.
In this paper we unpack:
- How we've redefined the playbook through our industry-leading strategy.
- Why most advertisers are under‑utilising AI Max.
- How AI Max acts as an execution layer for Paid Ads within Search+.
- Why mastering AI Max is essential to future‑proofing Search in an AI‑first world.
AI Max is not a shortcut. When designed correctly, it unlocks scale, relevance and future-readiness in Search that legacy structures can’t match.
