Been running 750+ accounts simultaneously so warm-up is something we've tested extensively. Here's what actually moved the needle for us vs what didn't.The Gmail warm-up before connecting Ads is the step most people skip entirely. 3-7 days of normal browser activity — Google Search, YouTube, some Gmail sends and receives — before the account ever touches Google Ads. The account needs behavioral history first. We use OmniLogin's auto-care feature to automate inbox activity at scale, but even manual is fine if you're doing a handful.After the Gmail is warmed, connect the Ads account and then wait another 48 hours before launching any campaign. Accounts that go live within hours of creation get flagged automatically. This single step dropped our early ban rate noticeably.On budget: start at $5-10/day, let the first billing charge process cleanly without touching anything. Don't add keywords, don't adjust bids, don't pause campaigns in that window. The first clean charge puts the account in a genuinely different trust state — after that you have more room to move.One thing nobody mentions: the proxy and browser environment matter as much as the account behavior itself. VPN is useless because Google checks canvas fingerprint, WebGL, fonts, screen resolution — changing IP alone leaves everything else identical to whatever flagged you before. Dedicated proxy per profile, anti-detect browser, one device per account.
Our ban rate is 15% monthly across the operation. Treating it as a workflow rather than a crisis is the only way to run at this scale — replacement pipeline always has warmed accounts ready to swap in.
