Can't click Ads with AdMob

I have recently finished an android game and I am struggling to enable my ads. They show just fine whenever I want them to, but I can't seem to click them at all. I think the issue may be within my manifest file, but through all my googling I found no solutions that seemed to work for me.

Here is my AndroidManifest.xml:

 <manifest
     xmlns:android="http://schemas.android.com/apk/res/android"
     package="com.unity3d.player"
     android:installLocation="preferExternal"
     android:versionCode="1"
     android:versionName="1.0">
     <supports-screens
         android:smallScreens="true"
         android:normalScreens="true"
         android:largeScreens="true"
         android:xlargeScreens="true"
         android:anyDensity="true"/>

     <application
         android:icon="@drawable/app_icon"
         android:label="@string/app_name"
         android:debuggable="true">
         <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="true" />
         <activity android:name="com.unity3d.player.UnityPlayerProxyActivity"
                   android:label="@string/app_name"
                   android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
             <intent-filter>
                 <action android:name="android.intent.action.MAIN" />
                 <category android:name="android.intent.category.LAUNCHER" />
             </intent-filter>
         </activity>
         <activity android:name="com.unity3d.player.UnityPlayerActivity"
                   android:label="@string/app_name"
                   android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
         </activity>
         <activity android:name="com.unity3d.player.UnityPlayerNativeActivity"
                   android:label="@string/app_name"
                   android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
             <meta-data android:name="android.app.lib_name" android:value="unity" />
             <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="true" />
         </activity>
         <activity android:name="com.unity3d.player.VideoPlayer"
                   android:label="@string/app_name"
                   android:configChanges="fontScale|keyboard|keyboardHidden|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen">
         </activity>
         <activity android:name="com.google.ads.AdActivity"
                   android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"/>
     </application>
     <uses-permission android:name="android.permission.INTERNET"/>
     <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
 </manifest>

This is located within Assets > Plugins > Android, the files I have located within here are as such:

• AndroidManifest.xml

• com.microeyes.admob.jar

• GoogleAdMobAdsSdk-6.0.1.jar

There are no objects in front of the ad. My game consists of an empty screen with few objects falling occasionally. These objects can (read: can't) be seen behind the Ad.

This line is one that I found from Unity Answers and may or may not be used properly here (Line 18):

 <meta-data android:name="unityplayer.ForwardNativeEventsToDalvik" android:value="true" />

I used This source (Android version) to create the ads. They generate just fine using the cs scripts, only touching them takes me to no source.

Within my Ad Manager file, I have input my AdMob code. However, I'm unsure if I need all of the information that I have put here. I am using the format:

ca-app-pub-XXXXXXXXXXXXXXXXX/XXXXXXXXXX

Each X representing a number (can't link that thing) - is this the correct format? I am unsure or if I should be using the "ca-app-pub" section, or if I need only the numbers from one side of the /.

Any help would be greatly appreciated, thanks. Any more required information can be given, but I believe this is all that is required.
