How to Avoid Association Risks in Multi-Account Campaigns?

Anyone running multiple Google Ads accounts has likely witnessed the "collective punishment" scenario—when the main account gets suspended for accidental policy violations, the backup account suddenly loses traffic; a new account just gains momentum, only to receive a "associated with disabled account" warning, with no appeal possible but to start over. Last year, our team had 6 Google Ads accounts, 4 of which were banned within 3 months. Just re-growing the accounts delayed us for half a year. After switching to Submatrix Cloud Phone, 8 accounts have run stably for 10 months without a single association warning. Here are 3 practical tips to avoid pitfalls: 1. IPs Must "Look Like Real People Online at Home"—Data Center IPs Will Only Hurt You Initially, to save costs, all 6 accounts used data center IPs. As a result, the new account’s CTR (Click-Through Rate) was suppressed below 1% right after approval. Later, we learned that Google Ads’ system has a "blacklist" for data center IPs, defaulting to labeling them as "bulk marketing accounts" Submatrix’s global residential IP pool was a lifesaver: the US site uses home WiFi in Los Angeles, the German site is tied to a residential network in Berlin, and each account’s IP is an independent real residential line. The most obvious changes:

Last month, the US site ran Black Friday promotions, with a single account’s daily spend hitting $5,000. Because the IP was "authentic enough," the system even provided additional traffic support, with ROI (Return on Investment) 30% higher than when using data center IPs. 2. Device Fingerprints Must "Be Unique"—Don’t Let Google See "Twins" This is the easiest pitfall. Many think changing IPs is enough, but Google uses "invisible features" like browser fingerprints and device parameters to lock associated accounts. Previously, we logged into 3 accounts using different browsers on the same computer, and the system directly marked the "device matching rate" of these 3 accounts as 98%. Submatrix’s "hardware-level isolation" solved this: each cloud phone corresponding to an account has a unique device fingerprint—from CPU model, graphics card parameters to browser font rendering, even the acceleration of mouse movement is different. When detected by Google, it will be judged as "8 completely different devices" operating. Now we run 8 accounts simultaneously: adjusting ad groups on the US site and testing materials on the UK site. Even with overlapping operation times, we’ve never received a "abnormal operation pattern" warning. Once, we deliberately had two accounts promote the same product (with different landing pages). The traffic and conversions were completely independent, and Google’s association detection system couldn’t "find any clues." 3. Operations Must "Resemble Real Human Trial and Error"—Don’t Let the System Think You’re "Botting" Google hates "mechanical 投放 (campaigns)"—for example, 8 accounts adding keywords or changing budgets at the same time is easily judged as "scripted bulk operations." Submatrix’s "simulated operation" feature helped us avoid this risk: Set different "active periods" for each account: the US account is mainly adjusted from 9-18 local time, while European accounts are concentrated from 14-22. The system records this pattern, reducing suspicious judgments; When uploading materials in batches, the system automatically adds "human trial and error" traces—some accounts deliberately rotate images when uploading, others rename files before uploading, avoiding recognition as "uniform template-generated content." Last month, when optimizing negative keywords for the German site, 8 accounts each added 50 words within 2 hours. Because the operation traces were "random enough," Google not only gave no warnings but also increased the quality score for two of the accounts. Solving Keywords:
