Stop Arguing Over Keywords! As Google Ads Enters the “Multi-Signal Era,” How Can Cross-Border E-Commerce Protect Conversion Rates?

Over the past year, a classic debate has been raging in the Google Ads media buying community:

But this question misses the mark entirely. It is not a matter of whether keywords are “dead”—it is that the role of keywords within an ad account has fundamentally shifted. They haven’t vanished; rather, they have been demoted from the absolute “protagonist” to just one of many signals within an AI-driven intent system.

💡 Advertiser Survival Tip: Moving into 2026, Google’s underlying AI risk control and auditing mechanisms have become increasingly stringent. Many independent station (DTC) sellers find that even when their ad logic is sound, their accounts frequently face traffic throttling or risk-control bans. Stable traffic acquisition relies not just on mindset upgrades, but on a healthy foundational setup. If you need Google overseas agency accounts, high-weight Google invoice accounts, a more stable ad environment, or ad-delivery support for high-risk industries, you can contact DOA MEDIA for professional account protection and optimization advice.


I. Google’s Fundamental Shift: From “Keyword Matching” to “Intent Understanding”

Google’s intensive product updates over the past two years signal an accelerated transformation from traditional “keyword matching” to “intent matching” and AI-driven systems. The following three underlying shifts will impact your media buying the most:

Shift 1: AI Overviews & AI Mode Hijack User Demand

Shift 2: Broad Match Becomes the “Intent Prediction Gateway”

The June 2024 Query Matching Update allowed Broad Match to integrate user search history, geographical location, and contextual nuance.

Shift 3: Moving Toward “Multi-Signal Intent Matching” (AI Max for Search)

Google Ads is moving from looking at “what keywords you bought” to a full-dimensional match of “Keywords + Landing Page + Feed + Creatives + User Behavior.”

Take AI Max enhanced momentum as an example: If you buy the keyword “travel stroller,” AI Max will automatically crawl your landing page. If your page states “one-hand fold” or “cabin approved,” the system might automatically expand your ads to terms you never bought, such as “one hand fold stroller” or “airplane carry on stroller.”


II. Your Product Category Determines Keyword Weight

Google’s shift toward AI does not impact every account equally. What truly dictates your level of vulnerability is where your product sits on the consumer decision journey:

                  /   \     1. Problem-Driven (Category C): Intent Signals > Keywords
                 /     \
                /-------\
               /         \  2. Scenario-Driven (Category B): Keywords = Intent Signals
              /-----------\
             /             \ 3. Direct Purchase (Category A): Keyword-Dominated
            /_______________\

Category A: Direct Purchase (Keyword-Dominated)

Category B: Scenario-Driven (Keywords = Intent Signals — The Core Battlefield)

Category C: Problem-Driven (Intent Signals > Keywords)


III. Cross-Border DTC Account Scaling: A 4-Stage Roadmap

For cross-border DTC brands with a monthly budget between $3,000 and $15,000, do not blindly jump straight into full Broad Match or PMax. We recommend a steady, step-by-step approach:

Stage 1: Lock in Certainty First (Do Not Rush to Scale)

Stage 2: Reconstruct Account Architecture Around “Intent”

Stage 3: Let the System Find “Unseen Traffic”

Stage 4: Sync Top-of-Funnel Awareness with Bottom-of-Funnel Conversion


IV. Summary

Keywords are not dead, but the era of relying solely on shifting keywords and adjusting bids in the ad backend is over. Google Ads has evolved into a holistic ecosystem that requires the synergy of “Keywords + Landing Page + Feed + Creatives + Strong Account History.”
