Google Ads Invalid Clicks: What Google Filters, What It Credits and What You Can Do

Last checked 3 October 2026 against Google's documentation. By Muhammed Abdul Kalam. Wasted spend

Quick fix

Google Ads invalid clicks, such as bots, accidental clicks or competitors clicking, are filtered automatically and not billed when Google catches them before your invoice. Later detections are credited as Invalid activity on a following invoice. Add the Invalid clicks column to see what was filtered before assuming you paid for it.

Add the Invalid clicks column to your campaigns table.
Look for Invalid activity adjustments on your invoices.
Open the Invalid Activity Credit Report in Report Editor.

What this error means

Invalid clicks are clicks that don't reflect genuine interest: bots, accidental taps, fraudulent placements or people clicking to waste your budget. Google filters most of them automatically, removes them from your metrics and bill, and credits ones it finds later.

Google's traffic quality team uses automated filters, machine learning and manual reviews to detect and filter invalid traffic.

Why it happens

1Bots and automated software

Automated software generates clicks and impressions that mimic people.

How to tell if this is you: Clicks spike with no matching sessions or engagement on your site.

2Accidental clicks and fraudulent placements

Ads placed too close to navigation buttons, clickjacking and ad stacking.

How to tell if this is you: Display or app placements send clicks that leave immediately.

3People clicking without interest

Competitors clicking to raise your spend, or publishers paying people to click.

How to tell if this is you: Repeated clicks with no enquiries, often at the same times.

How to fix it

Open your campaigns, click the Columns icon and search for Invalid clicks.
Look for Invalid activity adjustments on your invoices.
Open the Invalid Activity Credit Report in Report Editor for credited metrics.
Remember that billed cost already reflects adjustments for invalid activity.

How long it takes

Invalid traffic Google catches before the billing cycle ends is never billed. Traffic detected after the cycle ends is credited automatically in the next billing cycle, when appropriate and possible.

How to stop it happening again

Watch the Invalid clicks column alongside clicks.
Review where display ads appear, since poor placements cause accidental clicks.
Read a rise in invalid clicks as filtering at work, not necessarily a loss.

From my desk

Click fraud is not my first assumption. I look at placements, search partners and campaign types for weak traffic, and at the Invalid clicks column to see what Google filtered and credited. Poor targeting or a weak page often explains results better than fraud.

When to get help

Clicks rise sharply with no matching visits or enquiries and nothing appears as invalid.
You need to separate genuine low-quality traffic from invalid clicks across many placements.

Where can I see invalid clicks?

Add the Invalid clicks column to your campaigns table, and check the Invalid Activity Credit Report in Report Editor.

Why did my invalid clicks go up?

Google says an increase means its defences are actively protecting your budget.
