Google now shows invalid-click credits your CPA still counts

Google Ads now tells you how much invalid traffic it kept off your bill. It does not take that money out of the numbers you optimise on. The new card adds a third invalid-traffic figure to the two Google already had, and your cost per conversion still counts spend that Google later gave back.

What changed

On 12 November 2026 Google announced the Invalid Traffic Overview Card. Google says that “for the first time” advertisers can see “both the amount saved and the credits” for invalid activity. The help page puts the card on the Overview page with two metrics:

• Estimated savings: what Google’s automated protections saved, as an estimate.
• Credited cost: what Google credited back for invalid activity found after the billing period ended.

“View details” opens daily graphs, a campaign breakdown and links to the invoices that carry the credits. The card is rolling out gradually, so your account may not have it yet. Google also says it cut advertiser exposure to invalid leads by an average of 30% in 2026. It gives no baseline for that figure.

The read: three numbers, and your CPA uses none of them

Google now reports invalid traffic in three places, and each counts something different:

Where	What it counts	Is it in your campaign Cost?
Invalid clicks column	Clicks filtered before billing	No, already removed
Estimated savings (card)	An estimate of the cost of that filtered traffic	No, never charged
Credited cost (card, invoice)	Spend found invalid after the invoice	Yes, and it stays there

Google says the first and third numbers “are not directly related”. The third is the one that matters. Google freezes campaign metrics at the end of the month so they match the invoice. A credit found later shows up on the next invoice, but it “won’t retroactively adjust your campaign data”. So the Cost, Avg. CPC and Cost / conv. you read in the campaigns table still include the credited clicks. A click found invalid just after month end even lands in a different month from its credit.

The only place the credit comes off is the Invalid Activity Credit Report in Report Editor. It adds adjusted cost, adjusted clicks and adjusted cost per conversion. It covers Search and Performance Max only. Demand Gen, Display and YouTube credits reach the invoice and the new card, but no report nets them out of campaign performance.

An illustration, with numbers chosen for the arithmetic: a Search campaign spends $10,000 in October for 100 conversions. In November, Google credits $800 of October clicks. The campaigns table still says $100 per conversion for October. The credit report says $92. Judged on the first number, the campaign looks $8 a conversion dearer than it was.

The other gap: the clicks still reach your site

Filtering happens on Google’s side, after the ad serves. Google says plainly that invalid traffic “can still reach your website and lead forms”. Each filtered click can still load your landing page with a click ID in the URL, start a session in your analytics and submit a form. Google removes the click from its reports. Your analytics and your CRM keep it.

So more sessions with a gclid in your analytics than clicks in Google Ads is expected, and the gap grows with the Invalid clicks column. You cannot remove those sessions click by click: Google says an investigation “won’t be able to confirm if specific clicks were marked as valid or invalid”, and it only looks back 60 days.

The opposite happens too. Google’s definition of invalid clicks says a report can show more conversions than clicks: Google removes the invalid click, but the conversion stays if it is valid.

What to do

• Read CPA from the credit report for Search and Performance Max once a month closes, and set targets from adjusted cost per conversion, not the campaigns table.
• Do not reconcile Google Ads clicks with analytics sessions one to one. Compare the gap with the Invalid clicks column for the same dates. A gap that grows faster than that column is the case to investigate, inside 60 days, with server logs and GCLIDs.
• Qualify leads in your CRM before you send them back as conversions. Google’s filters keep bot clicks off your bill, not out of your forms.

Clicks and cost freeze when the month closes. Conversions do not: they keep arriving on past days for as long as the conversion window is open. So how far back can last month’s numbers still move, and on which platform?
