who this is for: Google Ads managers and e-commerce operators running Search or DSA campaigns who need to understand how keyword strategy has fundamentally changed — and what to do before September 2026.
why this matters now: three forces are converging simultaneously in 2026: match types have drifted to semantic rather than literal matching, AI Max for Search has exited beta, and DSA is being force-migrated starting September 2026. advertisers who don't act proactively will lose 2–4 weeks of performance stability.
the mental model shift: keywords are no longer a complete map of your eligible queries. they are directional intent signals that steer an AI system with a much wider matching radius than any match type implies.
critical deadline: September 2026 — forced DSA migration begins. new DSA creation disabled.
what this is: before touching a single campaign, you need to update your understanding of match types. the definitions you learned in 2018–2022 no longer reflect how these match types behave. Google now uses LLMs to assess semantic similarity between your keyword and a search query — intent-driven, not literal token matching.
💡 note: this is not a small change. an exact match keyword
[key lockers]now triggers for "digital key lockers" and "lockers with audit trail" — queries that share intent but not exact phrasing. if you're optimising based on old match type assumptions, you're optimising for a system that no longer exists.
the semantic drift — old vs. new behaviour:
| match type | what it used to mean | what it actually means in 2026 |
|---|---|---|
exact [keyword] |
verbatim query only | close variations, implied intent, reorderings — closer to old phrase match |
| phrase "keyword" | keyword in order, extra words allowed | meaning of your phrase in different contexts — closer to old broad match modifier |
| broad keyword | synonyms and related terms | LLM-powered intent clusters — reads landing page context and user history |
the practical implication:
