I'm a firm believing in On target ads. i turn off IAB and that would only show ad based on my content
I thought
viewing my site from a friends computer and i see totally non relevant ad showing "including Obama Mortgage Credit, Qbids $99.99 IPad, and other bs spam"
I alway view my site and make sure I'm in private browsing as not to be tracked by Google to view my ads to make sure they are on topic.
after a few test i noticed that ad are different from different.
EXCEPT I'm using the laptop "even in private browsing" i use the most to manage my adsense, google account.
Google could be showing you a totally different set of ads that it's showing your visitor?
Could your CTR could be dropping because the ad being shown to your visitors suck, but when your looking at them they look fine LMAO
REGARDLESS OF IAB BEING OFF!
Something you should def check.
get a friend computer on a different connection and browse you ads.
Anyone else noticing this?
