Key takeaways
Why does Google show many invalid clicks but hardly any credit?
Because the two numbers count different clicks. The column shows what Google filtered before billing, so you were never charged for it. A credit concerns clicks that were charged and only found to be invalid after the invoice. Google says it is normal that these numbers are "not directly related".
The sentence comes from Google's help page on invalid traffic. It says you may find many filtered invalid clicks in your campaign reports but small credit amounts in your billing documents, and that this is normal. You did not pay for them, and that is good for you.
According to Google, a rising column is a sign that its filter is working, not a warning. It can also rise because more invalid traffic arrives. Google also states that there is no industry standard for a normal rate of invalid traffic, so a number in the column cannot be called high or low by itself. You add the column yourself: in Campaigns, click the Columns icon, search for "Invalid clicks" and apply.
Something can still be open, just not where you might expect it: a third group of clicks, described next.
Which three kinds of invalid clicks are there?
They differ in when Google detects them. Clicks found before the billing period ends are not charged. Clicks found after the invoice are charged first and may be credited later. Clicks never found are charged and stay uncredited. Only the first two show up in Google Ads.
| When detected | Do you pay? | Where you see it |
|---|---|---|
| Before the billing period ends | No. The cost goes back into your campaign budget. | Column "Invalid clicks" |
| After the invoice | First yes, then a credit where appropriate and possible. | "Invalid activity" under "Adjustments" |
| Never detected | Yes. A credit comes only if the click is later found to be invalid, for example by a review. | Nowhere in Google Ads |
Google itself allows for the third group. The review request exists for invalid traffic that was not filtered automatically. Whether that group is large in your account, nobody can tell from the outside. All of this rests on Google's own description, which cannot be checked from the outside either.
What does that mean in euros?
Take a made-up example, whose numbers say nothing about real accounts. You are charged for 10,000 clicks at €1 each, so the invoice is €10,000. Filtered clicks cost you €0. Later 30 of the charged clicks are credited on another invoice, which is €30, so in total you pay €9,970.
The column in this example shows 1,000 invalid clicks. They cost you €0 because they never appeared on the invoice. The credit of €30 concerns 30 clicks you had already been charged for. If you put 1,000 clicks next to €30, you compare two things that have nothing to do with each other.
Only one question stays open in this example: how many of the remaining 9,970 clicks were invalid and never detected? Neither number answers it. The rest is the third group, and only your own measurement can give you a hint about it.
Where do you find your credit in Google Ads?
In Billing, under "Summary", open the card for the month, expand "Adjustments" and look for the line "Invalid activity". For a breakdown by campaign there is a report. Campaign figures stay unchanged after a credit, so it can look as if nothing happened.
- Billing, "Summary": on the month's card, expand "Adjustments". The line "Invalid activity" names the original invoice, the month of service and the campaign, as Google's help on adjustments describes.
- Report: in the Campaigns menu, open the report editor, then the template gallery, and pick "Invalid Activity Credit Report: Search & PMax". It breaks credits down by campaign and network and shows credited clicks. You can add adjusted costs as a column. It covers Search and Performance Max campaigns only and also contains credits for placements that violated Google's AdSense policies, so it is not only late-detected traffic. Google describes the report here.
- Card "Invalid traffic": on the overview page, with estimated savings and credited costs. Google is rolling it out step by step, so it may be missing in your account. The "estimated savings" are Google's estimate for filtered clicks, not an amount that comes back to you.
- Campaign figures stay as they are: Google freezes them at the end of the month, and a credit does not change them retroactively. Adjusted values appear only in the report.
- Paying by monthly invoice: through a manager account, the details of these credits can be hidden on the invoice (Google's help on invoice display). If the detail line is missing on your monthly invoice, check this setting.
Why does a click protection tool show different numbers than Google?
Because it counts by its own criteria, and it often flags clicks that Google already filtered and never charged. Google says so itself. A gap between a tool and the column is therefore no proof that you paid for the difference. That holds for our numbers as well.
Google cannot judge outside reports and gives no click-by-click comparison. Even after a review request, Google does not say which single click counted as invalid. Google also names two patterns that often mean little: the same IP address, which many devices can share, and zero-second visits, which can come from how analytics tools measure. According to Google, a rise in clicks can have other causes too, such as the season, a competitor that paused, or a changed budget or keyword list.
One example of a vendor figure: Lunio, which sells click protection, reports 5.0% invalid clicks across all channels. The basis is 414 million clicks in 88 retail accounts in monitor-only mode, status August 14, 2026, from its retail report. This is an average across all channels, not a benchmark for your account. Lunio says its numbers show what gets past the platforms' defenses. Google says such tools often flag what it already filtered. Nobody can settle that from the outside, and your account may look better or worse. Lunio does not name the markets of these accounts. Google's position is that there is no industry standard for a normal share.
What can you do if you suspect undetected clicks?
Keep the three groups apart, rule out ordinary causes, and secure your own logs. Then decide whether a review request is worth it.
- Note three values separately each month. The column, the "Invalid activity" line and your own count stay three lines. Do not net them against each other, because your own count can include clicks Google already filtered.
- Check the change history before you suspect bots. A changed budget, bid strategy or keyword list can explain a jump in clicks.
- Check your logs for the GCLID. The GCLID is the click ID Google adds to your landing page URL with auto-tagging. Check whether your server or shop already logs visits with it for the last 60 days. If not, start today, because you will have little to show for the time before.
- Request a review for the last 60 days. It is meant for clicks that were not already filtered. How to prepare it is in our article on rising click prices, and the logs must exist before you ask.
- Expect an answer, not a verdict on single clicks. Google may tell you about a possible credit, but it does not confirm individual clicks. A credit is given where appropriate and possible.
How does seacashback help you with this?
seacashback checks the clicks on your landing pages, excludes detected bots at account level and documents invalid clicks, so that you can report them to Google. That gives you your own measurement next to Google's numbers. It is not exactly the third group, because some detected clicks may already be filtered by Google, and it does not prove that Google owes you anything. Google decides.
Click protection changes neither the auction nor your bids. To the extent detected clicks would have been billed, it dampens on paper what a real click costs you in the end. Clicks Google would have filtered anyway save you nothing. Read how it works under How it works. For data on invalid clicks in shops, see the Click Protection Report 2026. It measures German shops, so treat it as a reference for that market only.
Frequently asked questions
Do I get a credit for the clicks in the "Invalid clicks" column?
No. Google filtered those clicks before billing, so you were never charged for them. A credit applies to clicks you were charged for and that were found to be invalid later.
Where do I see whether Google credited me for anything?
In Billing, under "Summary", open the month's card, expand "Adjustments" and look for the line "Invalid activity". For a breakdown by campaign, use the "Invalid Activity Credit Report: Search & PMax" in the report editor, which covers Search and Performance Max only.
Is it bad if the number of invalid clicks rises?
Not by itself. According to Google, a rising column means the filter is working, and there is no industry standard for a normal rate. It says nothing about invalid clicks that were never detected.
Will seacashback get me a credit?
That is not a promise we can make. seacashback documents invalid clicks so that you can request a review from Google. Google decides, and a credit is given where appropriate and possible.
