What should an agency check before a Google Ads AI agent touches client accounts?

By Tom Claydon, Co-founder, Nudge · Updated 21 Oct 2026

A Google Ads AI agent reads your accounts and, with some tools, changes them for you. Before one touches a client account, check six things: who approves each change, whether it is re-checked against the live account, whether budget rises are capped, whether any change can be undone in one step, whether every change is logged with a reason, and which accounts it can see.

Disclosure: Nudge publishes this guide and makes Nudge, a Google Ads agent for Claude. Facts about Google's tools come from Google's own pages, read on 21 October 2026.

What is a Google Ads AI agent?

Software that uses an AI model to work on your Google Ads account from plain-English instructions. It can answer questions ("why did cost per lead jump?"), suggest fixes, and with some tools make the changes.

There are three kinds today:

Kind	Example	Changes accounts?	Manager (MCC) accounts
Built into Google Ads	Google's Ask Advisor (beta)	Can set up campaigns from a prompt; Google says you keep "full editorial control" over AI-generated assets	Google says it is not available in manager accounts
A connector for Claude or another AI assistant	Google's Google Ads MCP server; hosted servers such as Nudge	Google's server: no, "strictly read-only". Hosted servers: varies	Varies by server
A standalone PPC platform with AI features	Optmyzr, Opteo, TrueClicks, Adalysis (see our Optmyzr alternatives)	Varies	Varies

Why do agencies need different checks from a single advertiser?

Because a mistake is multiplied. An agency runs many accounts for many clients, each with its own goals, budgets and rules. One bad change can cost a client money and the agency the client. An agent built for one advertiser may have no way to know that one client said "never touch brand" and another caps spend at month end.

The six checks

1. Does anything change without a named person approving it?

The safest agents propose and wait. Ask the vendor whether any setting lets changes run without approval, and who can switch it on.

2. Is each change re-checked against the live account just before it runs?

Accounts change between a suggestion and a click. A change built on yesterday's data can be wrong today. Ask whether the agent validates the change against the live account at the moment it applies it.

3. Are budget increases capped?

Ask for the cap in numbers, per campaign and per account, and whether going over it needs a recorded reason.

4. Can any change be undone in one step?

Google keeps change history for the past two years, but reversing a batch of edits by hand is slow. Ask whether the agent stores the state before each change and can restore it in one step.

5. Is every change logged with the reason?

You will need to explain changes to clients. Ask whether each change is recorded with who approved it and why.

6. Which accounts can it see, and how do you remove access?

Use a login with only the access the agent needs. Read-only is enough to try it. Check how to disconnect, and whether keys need rotating too.

If a vendor cannot answer all six in writing, keep the agent read-only until they can.

What about Google's own auto-apply recommendations?

Google Ads can apply some recommendations automatically. You manage this on the Recommendations page, under Auto-apply, where a History tab shows what was applied. For client accounts, check this page before connecting any agent, so you know which changes came from where.

How does Nudge answer the six checks?

Every change is a proposal. Nothing runs until you approve it.
Each change is validated against the live account just before it is applied.
Budget increases are capped at 20% per campaign and 25% per account per day; going over needs a recorded reason.
The state before each change is stored, so any change can be undone in one step.
Every change is logged with the reason.
It sees only the client accounts connected to it during onboarding.

Each client account also keeps its own plan and standing rules.

Watch out for: Nudge covers Google Ads only, works inside Claude only, and is in private access, starting with a free read-only audit of one account.
