The ability to search for ads is being rolled out to the Ad Review Center, part of the new AdSense interface. Right now, only a small set of publishers have access, but Google says they're working on extending it to more as additional publishers are invited to test the new interface.
Publishers will be able to search for ads a variety of ways including:
- display URL
- destination URL
- placement targeted to their site
- AdSense for mobile
- AdSense for feeds
Publishers will then be able to filter their search by allowed, blocked and new ads.
This should definitely help publishers gain better control of AdSense ads on their site, and perhaps monetize their sites better as a result.
