Welcome to our lesson on allowing and blocking ads.
Because your site and your users are unique, Adsense provides controls
that let you block certain ads and advertisers from appearing on your site.
In this lesson, we'll cover how to implement these different blocking options,
and how these changes may impact your revenue. Let's say your site is dedicated
to reviews of children's books.
knowing that you are catering to parents, educators, and children,
you want to make sure that only age-appropriate ads appear on your site
you also want to ensure that the ads for competing book review sites don't appear.
Like this example there are several reasons you may need blocking.
You or your users are sensitive to the content of a particular ad
and would prefer it not to show up on your site - for example politics,
sexuality, or religion. You want to block ads from a particular advertiser
because you're working with them directly or you want to block ads from
one of your competitors.
We want to provide the controls that you need to be comfortable with your ads,
but you should be careful not to use them excessively.
Allowing all ads, creates the most competition in the auction for units,
which produces the most revenue for your ads.
Keep in mind that the ads you see on your screen
are not necessarily the same ones the your users will see,
as ads are served up on our user by user basis. There are many different ways that
you can use Adsense blocking tools to meet your needs.
These options have a range have implications
for your ad serving and revenue. The first blocking method
is by general categories. Here you can block ads from categories such as
apparel, internet, real estate, and vehicles.
You can also click into each broad category and block a more specific subcategory.
If you can avoid blocking a whole category, and instead
only block a few sub-categories, it will have a less negative impact on your revenue.
Similarly, you can also block ads by sensitive categories.
Here you can block ads from categories the latest sensitive topics
such as religion, politics, and references to sex and sexuality.
Again, we recommend blocking as few of these as possible,
while still considering the needs of your side and your users.
For both general and sensitive categories, you can see what percentage
of your ad impressions
and your earnings from the last 30 days each category or subcategory represents.
These percentages can help you predict the impressions and revenue impact
the blocking a particular category may have. The percentage that
each category represents may add up to more or less than 100 percent
because ads may be classified in multiple categories
or not classified in any category at all. Your next blocking option
is by advertiser URL. This is where you can go to enter specific competitor URLs
with ads you do not want to appear on your site. Make sure to enter the top-level
domain without the WWW to show that all advertisers subdomains
are also blocked. In specific cases, you may want to block ads by ad network.
Ads from Google Certified Ad Networks are allowed to appear on your pages by default.
On this page, you can allow and block specific third-party ad networks.
Lastly, you can block individual creatives in the AdSense Ad Review Center.
Here, you can see all of the ads shown in your site
and block text or display ads by individual ad. You can search for ads
by keyword, ad type, time period, ad network,
or you can upload an image and search for similar creatives.
Learn more about the settings available in the Ad Review Center
in additional resources section. Check out the ad serving tab
to view additional blocking settings such as interest based ads
and expandable ads. There's one more important blocking tool available that exists
outside of the AdSense interface. In addition to blocking ads in your AdSense account,
you can install the Google Publisher Toolbar to block
ads while viewing your pages in a Chrome browser. The Publisher Toolbar
is a Chrome extension that lets you view up-to-date information
about your AdSense account, offers an overview of your earnings and performance,
and provides ad overlays with in-page reporting.
All in the settings and tools are available to you so that you can make
sure your ads are appropriate for your content and your users.
Please use them wisely.
