# Admob for Unity: clarification on use needed

I'm following this documentation by Google on how to integrate Admob ads into my game and I'm confused because of the following:

This documentation says I build by game and then I mess around with ads. (Section Unity plugin API tells me how to add ads and that's after the build instruction). Shouldn't it be vice versa? That I place those ads and build last?

Or, if I really do build first, where do I add those ads?

It's actually a mess.

Unity Ads and Google Ads are two different systems and it's still recommended (from my and other users experience) to use Google Admob, because it simply gives you more money.

In order to have working ads, you have to:

1. Add them through the code
2. Add the app to Google Play without testing the ads (app may be in alpha-beta phase, don't worry, it won't be public)
3. Add the app to the AdMob console (https://apps.admob.com/v2/home)
4. Create ads in the AdMob console (video, static, banners) and get their keys.
5. Put ads keys into the code (see below)

When you have ad ID's, you put them here:

using GoogleMobileAds.Api;
…
private void RequestBanner()
{
#if UNITY_EDITOR
#elif UNITY_ANDROID
#elif UNITY_IPHONE

Then, you can test your app, even by building in Unity and uploading directly to the phone/tablet. Remember to put ad's ID's to the code. You'll have your ads working.
• In order to publish apps on Google Play, you have to pay 25$. To run ads, you pay nothing. When you want to get the money you earned - you provide your card/paypal or something and they give you the money. I don't know how taxes work through Play, I don't pay taxes, and that's why I'll go to jail soon. I'm not sure if Google does that automatically. – Jacob Aug 20 '17 at 16:33 • Well I live in the European Union where it is automatic, so I don't have to worry :D As for you, I highly recommend getting it sorted out if you don't live around here. So the money just accumulates and when I want to, I get that money? Does this "buffer" have a limit there? Or not, because it's just numbers? – agiro Aug 20 '17 at 16:36 • Yeah, I live in EU aswell. I think it does it automatically. When I got my first item-purchase for 3$ they gave me 1.30$of total income ;O It's because of taxes and probably - Google's fee. I think that there's a limit you have to pass before getting the money. I'm sure it's 100$ on Unity Ads, not sure about Google. It gets calculated once a month. – Jacob Aug 20 '17 at 16:39
