ANDREW BRAGGINS: Hey,
everybody, and welcome back to the Mobile Ads Garage. I’m Andrew Braggins,
and with the help of my partner, Gary
the graphics guy, today we’re going to talk
about AdMob mediation. We’ll cover how it works, what
the pros and cons are, and then have screencasts
of iOS and Android of sample implementations. All right, Gary, let’s
get straight into my app so we can talk. When you request an ad from
AdMob like this banner, a whole bunch of advertisers
compete in an auction to see who’s willing to pay you
the most to display their ad. When the auction is
done, the winning ad is sent down to the
device for display. This competition
between advertisers is one of the ways AdMob helps
you maximize your revenue. Now, mediation is a way
to have competition, not only between
different advertisers, but between entire ad networks. When you make a request
for a mediated ad unit, the server returns a mediation
configuration, or stack. It’s a list of which networks
to request an ad from, ordered by which one’s
likely to make you the most money at that moment. The SDK looks at
that list and starts trying networks one at a
time, and the first one to return an ad wins. This is where AdMob
adapters come in. The mobile ad’s SDK
uses them to rap other networks’ SDKs so they
all have a common interface. The beauty of it
is that all of this happens automatically
under the hood. As long as you make sure the
other SDKs and their adaptors are built into your
app, there’s usually no other mobile work required. So the plus side
is that you have more networks of
advertisers competing for your impressions, which can
mean better fill rates and more revenue. The downside, though, is that it
can take longer to load an ad, and because you need
those other networks’ SDKs and adapters built
in, your app size is bigger than it would
be with just AdMob. Also, because you’re now
dealing with multiple networks, you have to register with
them, create ad units in their network, and so on. How those pros and cons
weigh out is up to you. A lot of smaller publishers
prefer the simplicity of using AdMob alone, while,
for others, the chance to increase revenue makes
the extra work worthwhile. All right, time to
get our hands dirty. Let’s take a look
at how you can use the AdMob console
to configure an ad unit to use multiple networks. It’s the first step toward
getting that mediation money. Is that Peruvian money? Why did you go to Peru? All right, then. OK, so if you’ve created
an ad unit before, you’re probably familiar
with this screen. This is the page
that lists all the ad units associated with an app,
in this case, my test app. I want to draw your attention
to the mediation column here, though. You can see I only have one ad
source competing for this unit, and I’d like to add another one. So I’ll click this
link and I get a view of the ad networks
assigned to the unit. And I can click the
New Ad Network button and choose a mediated network
to add to my own unit, and you can see there’s a bunch. For this video, I’ve actually
created a fake ad network with an SDK and everything. It’s called the Sample network. It’s just for this
recording, so you’re not going to see it here when
you set up your own ad units, but you’re going to want
real ads from a real network anyway, because they
result in a real check. And you can see I put
in an ad unit here. Because AdMob uses the same
SDK that you would normally, you do need to have an ad unit
for each mediated network. Right, so now I’ve
got two ad sources competing for my
impressions, which is great. One thing I also want to
mention is how they get ordered. So I can come in here and set
a hard estimate on the CPM for what I think that
network is earning me, and AdMob will use
that when deciding which network gets first try. AdMob also features something
called automatic network optimization, which can
order the networks for you based on how much
money they’re making. The server knows how
much you’re getting for AdMob ads, of course,
and for many other networks, if you allow it access
to your account, it can actually
pull reporting data and then put it to
use in determining which source should go first. Just make sure you’re
using optimization anywhere you see it offered. All right. Once you’ve got an
ad unit configured, the next step is to get
the project building with the mediated
SDK and its adapter. Let’s take a look at
how that works with iOS. First I’ll import the
mediated SDK and its adapter into my project. Then I just need to
rebuild my app and profit. OK, that’s money
from a board game. You’re an odd person. OK, here are my steps,
and I’m actually going to do the
first two at once. Here’s my app, and
this is the project that I need to get that
SDK and adapter into. So I’ll turn to the AdMob
mediation networks page. There will be a link for
this at the end of the video so you can find it easily. It’s a great resource for
anybody using mediation. It lists all our
mediation partners plus links to their SDKs,
adapters, and instructions, so you can find out the
exact steps for each network. Some networks, for
example, may have CocoaPods that you can
just add to your pod file and import that way, just
like you see me doing here. But my simple network
just uses a static lib, so I’m going to grab the files
and drop them into a group. Again, every network has their
own particular instructions, so make sure you check them
to see if they require linker flags like the Objective-C
flag for categories or any other additional steps. All right, so that’s it,
that’s all for the importing. Time to rebuild my app. And there’s my mediated ad. Thank you, Gary, but that’s
actually kind of the point. You’ll notice I
didn’t have to change any of my actual mobile code. Referencing the GADBannerView,
loading the request, none of that changed,
and yet AdMob was able to fetch the
configuration from the server, then call into
the adapter, which called into the sample SDK,
and then came back with an ad. Pretty cool, and the
only step left is profit. All right, so that’s iOS. Now let’s try Android. As you can see,
it’s the same steps. Import, rebuild, profit. Gary, those are skeeball tokens. OK, so here are the
four steps again, and we’re going to start with
importing the mediated SDK. Here’s my project that I’ll
be importing that SDK into, and the first question is,
where do I get the SDK? A great resource, again, is
our mediation networks page. There will be a link at
the end of the video. This page lists all of
our mediation partners and has links to their SDKs,
adapters, and instructions. The instructions
part is important because different networks
distribute their SDKs and adapters in different ways. Some might host them on
JCenter, for example, and I could come right
into my build.gradle file and just add a dependency
for them and their adapters. Some networks also bundle
the adapter into the SDK. So there’d only be one
artifact to import here. The most common
setup, though, is just JAR files, which is how
my sample network does it. So I’m going to
cut these back out. So I’ll drag and drop
the JAR into my project here and get it done that way. There’s the SDK. All right, so that was
the JAR for the SDK. Now I just need the adapter,
which goes in the same way. There we go. All right, so now I’ve got the
mediated SDK and its adapter imported into the project. Time to rebuild my app. And there’s my mediated ad. The AdMob SDK gets the
configuration from the server, goes through the adapter
to the mediated SDK, and comes back with an ad. The only thing left is profit. So that’s AdMob mediation. It’s a little more work, but
it’s also more competition for your impressions, meaning
more potential profit. Again, we use banners here
just to keep things simple, but you can do other formats
like interstitials and rewarded video as well. To help you along
the way, here’s a link to our mediation
networks page, which has a list of
all our mediation partners plus links to
their SDKs, adapters, and instructions. We’ve also got implementation
guides for iOS and Android. So check those
out, and as always, you’re welcome to bring
your technical questions to our support forum. And if you’ve got a question
about this video or an idea for something we should
cover, leave a comment below, and Gary and I will
see you next time. [MUSIC PLAYING]

  1. Andrew, when i press the warning icon on mediation of rewarded interstitial, what will do next? Please snd me detailed guide, or snd me video link

  2. Hi Andrew, thanks for the excellent videos!
    I currently have a couple of apps in the Play Store that exclusively use the AdMob network for ads. If I add another ad network (on the AdMob mediation screen), such as AdColony, include their SDK in my project, and rebuild, then publish this new version of my app… what happens to the older app, when it receives an AdColony ad, but is without the AdColony SDK because the user hasn't upgraded to the latest version of my app ?

  3. dear Andrew
    as far as i know , adview contain a link when I load ads to my apps! can I have this URL . Because I wanna share this ads when i see it's interestig!
    And i just wanna have few ads on my app, so can i list some ads and repost it on my app, do we have any solution for my issue
    thanks

  4. Very nice video i like it but i am developing a game in game maker studio and trying to use mediation, as it require to implement other networks sdks but game maker studio states that it doesn't require sdk and adapter implementation for mediation….bit confused….need help!

  5. I've been following all the tutorials on how to implement the ads into my application, I am just curious I have just the basics setup with two addsources one in which is Facebook. I am curious though, I have the adapter and sdk but where am I supposed to place these so the app runs both the generic adMob network plus facebook in the same adview that I have place in my layout.. Thank you

  6. In my Account the Button NEW AD NETWORK is not available.
    can some one tell me why is happens differently in my App?

  7. If I am using admob mediation , will the admob sdk take care of refresh rate for the adds shown by the other add networks ?
    Also if it is recommended to use Automatic refresh rate set to Google optimised in case if I am using admob mediation ?
    Thanks Andrew for the wonderful video , very useful.

  8. hey Sir
    i need one help

    i have an android app and admob has blocked ads for that app
    so can i make new admob account and integrate admob ads to my app again please reply ?

  9. If you want to implement ads from any network into your project in a matter of minutes, check out how Enhance can help you!
    Implement & update multiple SDKs in a few simple steps with Enhance : https://goo.gl/vv56Qm

  10. Your documentation should have a clear way to tell us how to use multiple networks when each of them require that AddMediationExtra when requesting an Ad, for example Vungle and Nend, how can i use them both ??

  11. you raised many questions than answering them for me x), anyway Thank you I'll stick with the normal ads until i grasp how it works and what is the best config and best networks

  12. Some people are saying that if we use eCPM floor then our Adsense account may be disabled; is this true ?? How much eCPM floor value is safe to use ?
