Low impressions in Intertiscials

[oangelo]

I am using this plugin for some time, I was using another admob plugin before. But I am noticing a very strange behavior, my impressions are ridiculously low for interstitials now. I am having more than 1000 requests per day and having less than 100 impressions. I am loging the receive, show, close and fail in google analytics, and I noted that there are very many results that fail, I am waiting for the interstitial to be loaded, still, the problem persists.

It seems to be an intermittent problem, since it seems to work perfect in my phone. But in production, I see many fails in the Analytics and low impressions in AdMob. My fill rate is 100%, that means that every time I request an ad, I get one. I know that my impressions will not be exactly the same as the number of request, because I am waiting to show the interstitial and the user can leave the app without seen it, but, according to my Analytics statistics, I should be having many more impressions.

Any help would be welcome.

Hi. I can't seem to reproduce this problem. And we also have the plugin in a lot of our own aps and it works fine. Does analytics show any crashes or exceptions for your app?

I am using this code:

var adReady = false;
var adTimer = true;
var adPluginLoaded = false;
var adBannerShown = false;
var lastCardName = 'none';

function initAd(){
  if ( window.plugins && window.plugins.AdMob ) {
    adPluginLoaded = true;
    var ad_units = {
      ios : {
        banner: 'secret',       //PUT ADMOB ADCODE HERE
        interstitial: 'secret'  //PUT ADMOB ADCODE HERE
      },
      android : {
        banner: 'secret',       //PUT ADMOB ADCODE HERE
        interstitial: 'secret'  //PUT ADMOB ADCODE HERE
      }
    };
    var admobid = ( /(android)/i.test(navigator.userAgent) ) ? ad_units.android : ad_units.ios;

    window.plugins.AdMob.setOptions( {
      publisherId: admobid.banner,
      interstitialAdId: admobid.interstitial,
      adSize: window.plugins.AdMob.AD_SIZE.LARGE_BANNER,  //use SMART_BANNER, BANNER, IAB_MRECT, IAB_BANNER, IAB_LEADERBOARD
      bannerAtTop: false, // set to true, to put banner at top
      overlap: false, // banner will overlap webview 
      offsetTopBar: false, // set to true to avoid ios7 status bar overlap
      isTesting: false, // receiving test ad
      autoShow: false // auto show interstitial ad when loaded
    });

    registerAdEvents();
    window.plugins.AdMob.createInterstitialView();  //get the interstitials ready to be shown                                                                 
    window.plugins.AdMob.requestInterstitialAd();                                                                                                             

  } else {                                                                                                                                                    
    //alert( 'admob plugin not ready' );                                                                                                                      
  }                                                                                                                                                           
}                                                                                                                                                             
//functions to allow you to know when ads are shown, etc.
function registerAdEvents() {
  document.addEventListener('onReceiveAd', function(){});
  document.addEventListener('onFailedToReceiveAd', function(data){
    setTimeout( function() {
      window.plugins.AdMob.requestInterstitialAd();
    }, 1000*30);
    window.analytics.trackEvent('Ad', 'Interstetial', "Error");
  });
  document.addEventListener('onPresentAd', function(){});
  document.addEventListener('onDismissAd', function(){ });
  document.addEventListener('onLeaveToAd', function(){ });
  document.addEventListener('onReceiveInterstitialAd', function(){
    adReady = true;
    window.analytics.trackEvent('Ad', 'Interstetial', "Received");
  });
  document.addEventListener('onPresentInterstitialAd', function(){ });
  document.addEventListener('onDismissInterstitialAd', function(){
    window.plugins.AdMob.createInterstitialView();          //REMOVE THESE 2 LINES IF USING AUTOSHOW
    window.plugins.AdMob.requestInterstitialAd();           //get the next one ready only after the current one is closed
    adReady = false;
    window.analytics.trackEvent('Ad', 'Interstetial', "Closed");
  });
}

//display the banner
function showBannerFunc(){
  if (adPluginLoaded){
    window.plugins.AdMob.createBannerView();
    adBannerShown = true;
  }
}

//display the interstitial
function showInterstitialFunc(){
  if (adPluginLoaded){
    if (adReady && adTimer){
      setTimeout( function() {
        adTimer = true;
      }, 1000*60);
      adTimer = false;
      window.plugins.AdMob.showInterstitialAd();
      window.analytics.trackEvent('Ad', 'Interstetial', "Show");
    }
  }
}

function closeBannerFunc(){
  if (adBannerShown && adPluginLoaded){
    window.plugins.AdMob.destroyBannerView();
    adBannerShown = false;
  }
}

Analytics tells me this:

And admob says I had 1169 requests and just 340 impressions, with a fill rate of 100%. I can't spot any mistakes in my code, but something is very wrong... Any ideas?

[sunnycupertino]

Because is certain countries Admob probably doesn't have such a big range of ads to show, and this line

setTimeout( function() { window.plugins.AdMob.requestInterstitialAd(); }, 1000*30);

Pings their server quite often if they fail to deliver ads. And then maybe they just block ad serving.

What I would suggest, instead of looking at how many failed ad requests you get, is to check how many times do you want to show an ad and cannot as a percentage of how many times you need to show.

I thought about that, that Google might not have ads to serve. But, AdMob say that my fill rate is 100%! Might be because of slow internet connection, the user can be having trouble dowloading the add, since I am in Brazil and the internet sucks. But I don't think this is the case, because using another plugin I was having a more plausible relation between requests and impressions, more than 50% of the requests turned in to impressions. Could not be the version of AdMob sdk or something like this?

[sunnycupertino]

Admob automatically downloads the latest sdk onto each phone as a part of the play services. The library you embed is not the one that gets used. I would say it has to do with the internet connection as you say, because in US and Europe this definitely is not a problem. Be careful not to make too many requests to the Admob servers also, this could also cause problems.
