# Click Fraud Protection for Agencies Managing Many Google Ads Accounts

Click fraud protection for agencies is less about any single account and more about running the same checks, the same way, across every client, with one named person responsible for each decision. Three accounts can survive on memory and good intentions. Twenty cannot. What follows is the operating model: baselines, cross-account patterns, a setup sequence, an exclusion policy and reporting your clients will actually read.

## Click fraud protection for agencies starts with a shared baseline

Before you exclude anything in a new client account, record what normal looks like. Use the same fields for every client so you can compare them later: clicks, cost, conversions, conversion rate, cost per conversion, Invalid clicks, and how traffic splits by device, location and hour. Keep it in one shared place, not in each account manager's head.

A Google Ads manager account helps here. It gives you one sign-in for every linked client account and lets you compare performance and run reports across several accounts at once. That makes the baseline a single report you refresh, not a dozen exports.

The baseline is what turns "it feels like there is more junk lately" into a statement you can defend to a client. It also protects you when a client blames fraud for a drop that was really a pricing change or a broken form.

## Look for patterns across client accounts

An agency sees something a single advertiser never does: the same source turning up in more than one account. If you manage several clients in the same vertical and metro, say personal injury firms in one city or HVAC companies in one region, a competitor or a click farm targeting that market will often hit more than one of them.

When a source is confirmed in one account, check the others in the same vertical and area for it. Remember that IP exclusions live inside each Google Ads account, at campaign or account level, so a source you block for one client is not blocked for another until you add it there. Do it deliberately, with a note, not as a blanket copy of every list into every account. Clients in different markets rarely share bad sources, and copying lists wholesale is how real customers get blocked. Our page on [click fraud for law firms](/click-fraud-law-firms/) shows how concentrated one vertical can get.

## A repeatable per-account setup sequence

Every new client should go through the same steps, in the same order, so nothing depends on who onboarded them:

1. Confirm access through the manager account and check that 2-Step Verification is on. Google strongly encourages it for every advertiser.
2. Remove old users and former agencies that still have access.
3. Add the Invalid clicks column and record the baseline.
4. Review location options. Presence or interest is the default. Presence alone is narrower and usually reduces impressions, which suits clients serving a fixed area.
5. Check which campaign types are running. Campaign-level IP exclusions are not available for Performance Max, video, hotel, app and Smart Display campaigns. Account-level IP exclusions apply to all campaigns, including Performance Max.
6. Note existing IP exclusions and how close each campaign is to the 500-address limit. See [the IP exclusion limit](/google-ads-ip-exclusion-limit/) for how to manage it.
7. Open the change log for the client and write the first entry.

## Write an exclusion policy before you need one

### Auto-exclude confirmed fraud, review the rest

Split decisions into two tiers. Confirmed fraud (clear repeated paid clicks with no conversions, bot traffic, known bad networks) gets excluded without debate. Suspect traffic (one odd visit, a pattern that might be a real customer researching) goes to a human for review. Writing this down stops two failure modes: account managers who block everything out of caution, and ones who block nothing because they are not sure.

### A named reviewer and a fixed cadence

"The team" does not review suspect lists. A person does. Assign one reviewer per client, or per group of clients, and a day of the week when the suspect list gets cleared. If the reviewer is out, someone else is named in advance.

### A change log for every account

Log every exclusion and every removal: date, source, campaign, reason, who made the call. When a client asks why traffic dropped in one region, you can answer in a minute. When you need to file a Click Quality Form request with Google, which covers only the past 60 days, the log plus server logs gives you the dates, campaigns, IP addresses and GCLIDs Google asks for. See [Google invalid click refunds](/google-invalid-click-refunds/) for the rest of that process.

## What breaks between 3 and 20 accounts

- **Checks drift.** Each manager develops their own habits and the clients stop getting the same level of care. A written sequence fixes this.

- **Lists go stale.** Exclusions added a year ago are never reviewed and quietly fill the 500-address limit.

- **Nobody owns the gray area.** Suspect traffic piles up because no one is responsible for deciding.

- **Reporting becomes copy and paste.** Clients get the same paragraph every month and stop reading it.

- **Logins multiply.** Separate tools and dashboards per client make the weekly pass slow enough that it gets skipped. Block Click Fraud's [Agency plan](/agencies/) was built for this: up to 20 client sites, one login and a per-client view.

## False positives cost more than they look

Blocking a fraudulent source saves you the next click. Blocking a real customer costs you every future lead from that person, and it never shows up in a report. You just see slightly fewer conversions and no explanation. On high-value accounts, one wrongly blocked office network or shared mobile range can cost more than the fraud you were trying to stop.

That is why the suspect tier exists, why removals belong in the log next to additions, and why asterisk range exclusions deserve extra care. Never block Googlebot or AdsBot; [good bots you should never block](/good-bots-never-block/) lists them.

## Report in client language

Clients do not want IP addresses. They want to know whether their money is being protected and what you did about it. A monthly note should cover what changed against the baseline, roughly how much suspect traffic was found and acted on, any credits that appeared under Billing, then Summary, as "Invalid activity", and what you plan to watch next. Our guide to [reporting click fraud to clients](/report-click-fraud-to-clients/) has a template.

To compare plans, [see Block Click Fraud pricing](/pricing/).

## Frequently Asked Questions

### Can I add one IP exclusion list to every client account at once?

IP exclusions are set inside each Google Ads account, at campaign or account level, so you add them account by account. That is no bad thing. Sharing a list across clients in different markets is a common way to block real customers.

### Who at the agency should review suspect clicks?

One named person per client or client group, on a fixed day each week. Name a backup in advance. Without a named owner, suspect lists grow and nobody decides.

### How should agencies report click fraud to clients?

In plain language, monthly, against the baseline. Say what changed, what you blocked and why, and any credits Google applied. Skip raw IP lists unless the client asks.

### Does click fraud protection work on Performance Max campaigns?

Campaign-level IP exclusions are not available in Performance Max, but account-level IP exclusions apply to all campaigns in the account, including Performance Max. Block Click Fraud writes fraud sources to the account-level list as well, so Performance Max campaigns are covered.

### Can an agency get click fraud refunds for clients?

You can request an investigation through Google's Click Quality Form for the past 60 days, with the customer ID, dates, campaigns and server logs. Google decides whether to credit anything and will not confirm which clicks it judged invalid.
