Yes. To create and manage a filter list of websites whose ads you'd like to
restrict from showing on your site or AdSense for search results pages, simply
log in to your account at https://www.google.com/adsense
and click the Competitive Ad Filter link below the AdSense
Setup tab.
You
can create separate filter lists for your content pages
and for your AdSense for search results pages. Ads for
the websites that you add to your competitive ad filter
list typically will not run on your pages, but remember
that filtering sites may decrease the number of ads that
can appear on your pages as well as decrease your
potential earnings.
For
more details on using your competitive ad filter, please
read the Filtering
Ads section of this FAQ Google AdSense.
Google
AdSense also combine an editorial team and filtering
technology to maximize the quality of the Google ads on
Google and publisher sites:
-
Review:
Across the Google network, ads are reviewed
using a combination of human and automated processes
before they are shown on publishers' sites. The
review process takes into account a variety of
factors, including the quality of the ad and whether
the ad is suitable for all audiences.
-
Sensitive
content filters: At times, certain ads may
not be appropriate to run on all pages. For example,
Google automatically filters out ads that would be
inappropriate on a news page about a catastrophic
event.
Please
note that Google does not commit that all ads for the
websites that you add to your competitive ad filter list
or ads containing objectionable content will be
prevented from display on your site.
