Click fraud in Google Ads — what gets filtered and what you get back
The worry is common and reasonable: a competitor, a bot or an accidental double click burns budget meant for real prospects. What Google actually does about it — and what it does not — is in its own documentation.
What counts as invalid traffic
The definition is broader than fraud: "Invalid traffic refers to clicks and impressions on ads that aren't a result of genuine user interest, including intentionally fraudulent traffic and accidental or duplicate clicks." (Google Ads Help)
So it covers deliberate manipulation, but also accidental and duplicate clicks — the cases nobody pictures when they say click fraud, and in practice the larger share.
You are not charged for it
The sentence that matters for budgeting: "You won't be charged for invalid clicks or impressions as they provide little or no value." (Google Ads Help)
Filtering is automatic, not something you apply for. The Invalid clicks column in your reports shows what has already been removed — it is a record of what the filter caught, not an outstanding bill.
A credit is not a refund
This is where most expectations go wrong, and Google is explicit: "You won't receive refunds for invalid traffic" — and then: "Clicks determined to be invalid will result in adjustments or credits, not a refund." (Google Ads Help)
| When it is detected | What happens |
|---|---|
| Before the invoice is issued | The cost is never charged in the first place |
| After the invoice is issued | A credit, set against future costs |
In practice: money does not come back to your account, it reduces the next bill. Budgeting for a repayment is budgeting wrong.
What this means for your expectations
Three honest points that click-protection vendors tend not to lead with:
- A layer of protection is already built in and costs you nothing.
- What the filter catches is visible to you in the invalid clicks column — it is checkable, not a matter of trust.
- Suspicious patterns (one location, one time of day, high click rates with zero conversions) are still worth looking at yourself — the filter is not the only tool, and targeting exclusions take effect immediately.
That said, when clicks arrive but never turn into anything, click fraud is rarely the explanation. Search term selection or the landing page usually is — see the guide to clicks and ad quality and the cost guide.
