I changed all my ad targeting categories for all my sites at 3am EST, Friday March 24, but 12 hours later I still see the ads of my previous targeting caregories on ALL my sites. Anybody else had the same problem?
Lex, YPN has stated that for the site targetting feature to take full affect make take up to 4 days. As well, within the past two months they have increased their targetting which takes precedents, so playing with the ad targeting feature may not do much good.
If your ads are that far off, you could instead try blocking the ads completely instead of switching the ad category, or perhaps try both.
