It's a common point of confusion, but Google Ads does not provide a report that explicitly shows "clicks prevented by your manual IP exclusion list." This is not an error; it's simply how Google's reporting is designed.
Here’s a breakdown of what’s happening:
It shows you the clicks that were delivered to your site after Google's own internal filters removed what it considers "Invalid Clicks."
It does not report on events that were prevented from happening. Your manual IP exclusion list acts like a bouncer at the door—it turns people away before they can enter. Google Ads reports on who got inside, not on who was turned away.
Since you won't see this data in a standard report, the only way to verify that your manual blocks are active is to check the source directly within your Google Ads account.
Navigate to the settings of the relevant campaign.
Find the "IP exclusions" list.
If the IPs you intended to block are on this list, you can be confident that the block is active and working as intended.
The platform identifies fraudulent or low-quality clicks and shows you the ones that have been blocked.
This is precisely how your "Total Estimated Savings" are calculated. ClickSambo highlights the money you didn't spend on wasteful clicks, providing a clear measure of the effectiveness of your blocking strategy.
In summary: Use your Google Ads settings to confirm a block is in place. Use your ClickSambo dashboard to measure the financial impact and effectiveness of that block.
