01The Direct Answer
Why am I paying for clicks from sites and apps unrelated to my product?
Direct Answer
Because your search campaign is, by default, also running on partner sites and possibly on the Display Network, and neither is the same audience as someone typing your keyword directly into Google.
According to Google Ads Help, the Search Network includes Google's own properties plus third-party search partner sites, and the option to include those partners is on by default when a campaign is created. The Display Network is separate and requires its own selection, but once turned on, it shows placements and lets you exclude them one by one, which the Search Network with partners does not.
02The Two Networks You Never Chose
Visible waste and invisible waste
Display Network
You can see where the click landed
According to Google Ads Help, placements in the Display Network show which sites and apps the ad ran on, and each one can be excluded individually.
Search partners
You cannot see the site, only the checkbox
According to Google Ads Help, the specific partner site is disclosed only inside Performance Max reporting, so an ordinary search campaign gives you an on/off switch and no visibility into which sites are included.
That difference in visibility is why partner clicks are the one most industrial accounts never audit: there is nothing to look at, only a setting to reconsider.
03What You Can Actually Control
Two settings, checked twice a year
The Review
1. Open campaign settings
Check whether "include Google search partners" is marked.
→
2. Open the placements report
For any campaign with Display enabled, sort by cost and review the worst performers.
→
3. Compare performance with and without partners
Pause search partners for one cycle and compare cost per opportunity before deciding.
A broader checklist for negative keywords that reduces waste across every network at once is in the blog post on segmenting Google Ads for B2B.
04When Leaving It On Makes Sense
This is not always a mistake to fix
Search partners and Display can still be worth keeping on for an account with enough volume to test them properly and separate reporting to isolate their performance. The mistake is not the setting itself; it is never checking whether it is paying off, because it was never visible enough to prompt the question.
For an account still learning where its budget goes, the safer default is turning both off, measuring the core search campaign on its own for one full cycle, and only reintroducing partners as a deliberate test with its own tracked cost per opportunity.
05FAQ
FAQ
Why am I paying for clicks from sites and apps unrelated to my product? +
Because a search campaign includes search partner sites by default and, when Display is selected, apps and websites in that network too. According to Google Ads Help, the search partner option is enabled at campaign creation and can be turned off; Display placements can be reviewed and individually excluded.
Can I see which partner site my ad appeared on? +
Not in an ordinary search campaign. According to Google Ads Help, the specific search partner site is disclosed only in Performance Max reporting. Outside of it, you get an on/off setting with no list of sites.
Should I turn off search partners for good? +
Turning it off is the safer default while you cannot see where the clicks land. If you have enough volume to test it properly, with separate reporting isolating that traffic, it can be worth reintroducing as a deliberate experiment instead of a default you never look at again.
Is Display the same thing as search partners? +
No. According to Google Ads Help, search partners are third-party search sites bundled into the Search Network, while the Display Network is a separate group of apps and websites that requires its own selection. Display shows individual placements you can exclude; search partners do not.
How often should I review these network settings? +
At least twice a year, and every time a new campaign is created, because the default settings apply again unless someone changes them. It takes minutes to check and it is one of the easiest leaks in this hub to close.
Does Performance Max have the same problem? +
Performance Max spends across several networks at once and, unlike a plain search campaign, at least discloses a channel breakdown. The specific budget-allocation question for that campaign type is treated on its own page in this hub, since the controls available are different.
Will turning off search partners reduce my traffic a lot? +
It usually reduces the volume of clicks you cannot audit, which is the point. Whether that changes your total opportunities depends on how much of that traffic was ever converting, which you can only know by comparing a cycle with it on against a cycle with it off.
Where do I start if I have never checked this before? +
Open the settings of your main search campaign and check the search partners box. Then open the placements report for any campaign with Display enabled and sort by cost. Those two screens usually take less than ten minutes and often expose the largest single leak in a first audit.
