Site owners will see lower bidding advertisers because your behavior on the site is unattractive to advertisers. Few ads competing for someone visiting multiple times a day etc.
Shady ad networks used to hide these from site owners. We don’t because it’s bad for auction history.
I wouldn’t worry too much unless it’s counter to your site (sober living site seeing alcohol ad or something) because what you see won’t ever reflect how a visitor might be targeted
