Google Ads Invalid Click Credits: How Refunds Really Work

If you've paid for clicks that look fake, you can get money back from Google Ads, but not as a refund. Google issues invalid activity credits. Most invalid clicks are filtered out before you're ever billed, and the rest show up later as a credit on a future invoice. Knowing how that works tells you when a request is worth filing and why some requests go nowhere.

Google defines invalid clicks as clicks that don't come from genuine user interest. That includes manual clicks meant to drive up your costs, clicks from bots and automated clicking tools, and accidental clicks with no value to you, like the second click in a double-click.

There are three layers:

1. Real-time filtering: Google's systems remove most invalid clicks before they're billed. You aren't charged for them, and they're filtered out of your reports.
2. Later detection and credits: If invalid traffic is caught after your invoice closes, Google issues a credit. It appears as a negative amount on a future invoice and in your transaction history.
3. Your investigation request: If you believe you're still paying for suspicious clicks, you can ask Google to investigate through the click quality form.

One hard limit applies to all of it: both Google's automatic analysis and manual investigations only cover the last 60 days of traffic.

Start by looking at what Google has already caught. It saves you a request that would come back empty.

1. The Invalid clicks column. In your campaigns table, open Columns and add "Invalid clicks." This is the number of clicks Google filtered out automatically. You were never charged for them, so this number is not the amount you're owed.

2. Billing adjustments. Go to Billing › Summary and open the card for the month in question. If you see "Invalid activity" under Adjustments, Google has already credited you for that period.

3. The Invalid Activity Credit Report. Go to Campaigns › Report editor › Template gallery and open "Invalid Activity Credit Report: Search & PMax." It covers Search and Performance Max campaigns only and shows credited clicks, credited interactions and credited amount by campaign, plus adjusted cost, clicks, interactions, CTR, average CPC, conversion rate and cost per conversion after credits. Clicks right before a billing cycle closes may be credited the following month, and small rounding differences can appear. Neither is an error.

4. Change history. Did anyone change bids, budgets, targeting or keywords during the suspicious period? A sudden cost spike sometimes has a settings change behind it. Rule that out first, or mention it in your request.

5. The 60-day rule. Check the dates of the suspicious clicks. Activity older than 60 days can't be investigated.

Google asks for the following in an investigation request:

1. Your 10-digit Google Ads customer ID

2. The exact date range of the suspicious activity

3. The campaign and ad group names involved

4. Keywords that seem to be driving abnormal traffic

5. Web server logs: IP addresses with repeated clicks or no conversions, user agents (browser and device info), and the GCLIDs (Google click IDs) tied to the suspicious clicks

6. A short explanation of why the traffic looks suspicious, such as a sudden jump in clicks with no matching rise in conversions, or clicks from outside your targeted area

If the problem is low-quality form submissions, include the GCLIDs of the suspicious leads as well.

Pulling these logs by hand can take hours. The next section shows how to get them in a few minutes.

ClickSambo already records the data Google asks for, so the report takes four steps:

1. In your ClickSambo dashboard, open Report Sending.

2. Select the Google Ads Refund Report card.

3. Set a start and end date within the last 60 days and click Send Report.

4. You'll see a confirmation, and the report arrives in your inbox as an Excel file within a few minutes. The same page links to Google's refund form and to this guide.

The Excel file has four sheets, each covering something Google asks for:

The strongest evidence usually sits on the last sheet. In one real report from a local service business, a single device used 95 different IP addresses and clicked the ads 315 times in four weeks. That's hard to explain as real user behavior. For a full case, see how one business grew leads 8x and secured a Google refund.

ClickSambo is on Google's official list of certified click trackers , so the data in your report comes from a certified tracking system that works within Google Ads.

You file the request through the click quality form. It covers invalid clicks, low-quality form submissions, clicks from outside your targeted locations and sudden short-term cost spikes. Attach your Refund Report Excel file.

For the field where you describe the problem, adapt this template with your own numbers:

Customer ID: [XXX-XXX-XXXX]
Date range: [MM/DD/YYYY – MM/DD/YYYY]
Campaign / ad group: [Campaign name] / [Ad group name]
Suspicious keywords: [keyword 1], [keyword 2]

During this period, clicks on [campaign name] rose by [increase vs. prior average] without a matching rise in conversions. Our logs show [X] IP addresses clicking [Y] times each, and [Z] devices clicking repeatedly from different IP addresses. Logs with IP addresses, user agents and GCLIDs are attached. We'd appreciate a review of this activity.

Keep it short and specific. Give numbers, keep commentary to a minimum.

Common outcomes and how to respond

Google doesn't publish its response templates. These are the situations where requests most often stall:

"These clicks were already filtered or credited." Check the credit report and your billing adjustments. If you still believe you paid for clicks that weren't credited, list those clicks with their GCLIDs and file again.

Your data isn't taken into account. Present your evidence under Google's own headings: IP, user agent and GCLID. The GCLID is the most direct way to match a click to Google's records.

"The request is outside the 60-day window." This limit doesn't bend. File the same week you notice a suspicious spike.

No credit at all. Google doesn't share detailed reasons. You can file again for a new period with clearer evidence, especially devices clicking from many IPs.

After a credit comes through

Investigations usually take a few business days, and you'll get the result by email. A credit appears under Adjustments as "Invalid activity" on the month's card in Billing › Summary, and as a negative amount on a future invoice. For campaign-level detail, use the credit report.

One quirk: in rare cases a click is removed as invalid but its conversion isn't. That's why conversions can occasionally exceed clicks.

Credits work backwards. The money is spent first, and some of it may come back. The window is 60 days and Google makes the call. The more efficient approach is to stop the same sources from draining your budget again and again.

ClickSambo analyzes ad clicks in real time. It flags suspicious clicks as invalid and automatically excludes their sources in your Google Ads account, so the same source stops seeing your ads. On the Enterprise plan, it sends only clean conversions back to Google as offline conversions, so your bidding learns from real customers, not fake traffic.

If an attack hits suddenly, Circuit Breaker pauses only the keyword, device or location under attack for 15 minutes, then restores it automatically.

And when you do need to file for a credit, the evidence is ready: the Refund Report lands in your inbox in minutes.

One more thing: Google can't block fake form submissions on your site for you. For forms, it recommends server-side validation and double opt-in.
