Google's AI now runs your ads. Who audits the AI?
Ads Advisor, auto-applied recommendations, AI Max query expansion — Google's automation changes your account every night, and Google's own advisors will never recommend spending less with Google. LeakStop is the incentive-clean auditor: a continuous change-log of everything the AI did, wasted-spend detection, and a verifiable "money you saved" ledger. Read-only by design.
Upload a search-terms export, get the leak report in minutes. No Google account access, no install, files deleted after 24 hours.
Automation by default
Google may now "format, select and generate" ads on every account — no re-acceptance asked. Whatever the automation does, the invoice and the liability are yours.
AI Max takes over
DSA campaigns start auto-upgrading to AI Max: broader-than-broad matching, auto-rewritten ads, URL expansion — query expansion at Google's discretion.
10–30%
of unmanaged spend is recoverable waste in agency audits (Lunio's 2.7B-click study puts the invalid-traffic floor alone at 8.5% — $63B globally).
How it works
The audit trail Google's UI will never show you
Start with a CSV export, or connect your account read-only through the official Google Ads API. Either way LeakStop never touches your budgets or campaigns — v1 issues no write calls at all. Exactly what we read, and what we never do →
AI-activity watchdog
A continuous, plain-English change-log of everything Google's automation did to your account: auto-applied recommendations, advisor-applied changes, auto-created assets, AI Max expansion.
"Google's AI changed match types on 14 keywords overnight — here's what it cost."
Leak detection
Six detection rules on your search terms and spend: broad-match and AI Max query bleed, n-gram waste, budget creep, spend anomalies — flagged with the evidence attached.
Guided fixes deep-link into the exact Google Ads screen. You stay in control of every change.
The savings ledger
Every verified fix is metered against a 28-day baseline into a conservative, evidence-linked "money you saved" report — weekly, white-label, client-ready.
The receipt that renews retainers: under-claims by design, so every dollar on it defends itself.
Start with a file — zero access
Download the search-terms report from your own Google Ads account and upload it. The same six detection rules run against it, and you get the leak report in minutes. No Google login, no permissions granted, no install — the file is deleted after 24 hours.
Or connect read-only via the Google Ads API
A paid plan connects your account through Google's own OAuth consent screen and syncs it nightly through the official Google Ads API. We read five reports — search terms, campaign metrics, change history, and account settings — and write nothing back. There is no mutate call anywhere in the product.
Why LeakStop
Google's advisor works for Google. LeakStop works for you.
