I'm missing the point of mediation, how can I mediate admob ?

[Romain Bitard]

Hey everyone, I'm missing something.

When you load an ad

you provide an adUnitId.

How can I handle 3 adUnitIds (with 3 != ecpm floors for example).

because I don't understand how then admob map each admob adUnitIds to other ad providers since we provide here only one adUnitId.

Do we have to Load all the adUnitIds ourselves ?

If I have 3 adUnitIds I have to handle them all in code myself? That's the point of mediation to me.

Thanks in advance for your help

Cordially,

Romain

I think I understood but not sure.

You create an adunit (adUnitA) that you'll use in your code (LoadAd(adUnitA))
Then you create as many ad units as you need (adUnitB, C, D)

You create a waterfall and map them to other ad providers.
Admob will use adUnitA in his bidding process get back with a ecpm value then will check each waterfalls in order using the other adunits

Am I correct ?

I think I understood, for the waterfall do like this capture. Am I correct ?

Hi Romain,

Thank you for reaching out to us.

With regard to your concern, kindly check this article (https://support.google.com/admob/answer/13420272?hl=en&sjid=3602029863028250290-AP) for a guide to AdMob mediation (bidding & waterfall). In the steps provided on it, it was mentioned that you need to first create your ad unit id and set your ad resources, then you can now map it in your mediation network that you want to use. Kindly make sure that you followed the documentation guide (https://developers.google.com/admob/android/choose-networks) for mediation before implementing it in your application to avoid any errors.

Thanks for the reply. I checked but I don't understand how I can do a waterfall with admob.

I can only create one adunit with admob and map all the other ad sources to this ad unit (all the waterfalls and bidding), am I correct ?

I can't create 3 ad units in admob and use them all in the mediation too.

Thanks for any help you can provide

Hi Romain,

Thank you for your response.

Kindly check this article (https://support.google.com/admob/answer/3245073?hl=en&sjid=15857224518674500810-AP) for the list of mediation network where Waterfall ad sources available. Then, as per this article (https://support.google.com/admob/answer/13420272?hl=en&sjid=3602029863028250290-AP), you're correct that you can create an ad unit id and map your third-party ad source to fill your ad request. You can still create multiple ad unit ids, but you can only map the ad sources on each ad unit id that you want to use.

Thanks a lot for the reply, I checked thoroughly the links.

You can't do what I did with Ironsource levelplay for example :

Having 3 admob ad units in a waterfall (with different floor tiers) + 1 admob adunit in bidding ?

What you can only do is having an ad unit for admob and map all the other ad sources to this unique admob ad unit ?

Like the capture below the first circle marked "BAD" was when I tried to do an admob waterfall but those adunits where never used in the code to load an ad

the second circle is the correct way and only way to use mediation if I understood correctly.

Am I correct ?

Hi Romain,

You can create multiple Ad Units and add a mediation into it. Would you able to share to us your goal, so we could provide precise guidance to your use case?

[Romain Bitard]

Thank you, I will do that.

I want to create 3 adunits for admob 5/10/15$ ecpm floors for waterfall only

And I want to use 1 admob adunit for bidding.

That's the setting I currently use for Ironsource Levelplay.

Can I do that with admob ? How ? I searched the documentation but all I could find was creating one admob adunit and mapping other ad sources to it (unity, meta, etc.)

[Romain Bitard]

I want to do this basically using "X" for bidding, then "a" "b" "c" as waterfall because I have set them to specific floors.

Is that possible ?

In the code I just use "X" when I load adunits and admob take care of the mediation or I do have to load them all myself  and decide to display "x", "a", "b", "c", if the adunits successfully loaded ?

Hello Romain,

To setup a waterfall ad source, you can refer to this document: https://support.google.com/admob/answer/13404328?hl=en. Feel free to reach back to us if you have any further concerns or inquiries.

Hello,

Thanks for the reply.

I already read and did that. What I don't understand is how to do a waterfall using admob adunits.

Please check my corresponding image.

In the code I use "interstitial_opti" adunit. Are the other 3 (admob5, admob10, admob15) picked up automatically by admob because I set them up here or are they dismissed and not used because nothing link to them ?

Hi Romain,

Thank you for your response

Can you confirm if you already checked this article (https://support.google.com/admob/answer/7374110?hl=en&ref_topic=13397014&sjid=4636927324620638521-AP) with regard to Optimize waterfall ad sources in mediation? In addition to that, as per our article (https://support.google.com/admob/answer/13420272?hl=en&ref_topic=13397014&sjid=4636927324620638521-AP), you can create multiple ad unit ids, but you can only use it to map with your third-party ad source to fill your ad request.
