For ads on search (not display)
Been beating my head against a wall trying to figure out why we have some keywords with an average CPC higher than the set max CPC.
Checked all the bid adjustments, nothing. Checked the rules timing, maybe some clicks before rules changed the bid, nothing.
No enhanced CPC enabled.
Paying for clicks, not conversions.
And then, digging into it more I found this little tidbit regarding search partners network:
Google search partners are sites in the Search Network that partner with Google to show ads on their search results. To help you get a similar cost per conversion as you get on the Search network, some clicks on the Search partner network may cost more or less than your Google Search Max. CPC bid. Search partner performance won't impact your Search Quality Score.
Come on google...
