Load Google Ads after entire page has loaded

问题

Without Google Ads, my HTTPS webpage loads in about 500ms. With Google Ads, the same webpage takes 2-5 seconds to load. I have two banner ads (one at the top and one at the bottom). Yes, it renders the entire page before the ads, but I still think it's clunky to have the browser spinning while it waits for the ads to finish.

Is there any way with Javascript to finish page loading before the ads, and then just load the ads in the background? Basically, trick it into thinking the entire page is already loaded?

Current code:

<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<!-- My Ad Banner -->
<ins class="adsbygoogle"
     style="display:inline-block;width:728px;height:90px"
     data-ad-client="myid"
     data-ad-slot="myid"></ins>
<script>
(adsbygoogle = window.adsbygoogle || []).push({});
</script>

Looking at the waterfall for my site, it doesn't look like the adsbygoogle.js is causing the load indicator. Instead, it's the actual ad content itself. For example, this object (the banner ad) doesn't even start loading until 1.8 seconds (long after my entire page has already loaded): tpc.googlesyndication.com/simgad/AdID

Thanks!

Try this article.

The trick is to put your ad initializing and loading logic in window's onload event:

<script>
   window.onload = function(){
       ...
   };
</script>

This is my ultimate Vanilla JS solution:

<script async defer src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>
<script>
    (adsbygoogle = window.adsbygoogle || []).onload = function () {
        [].forEach.call(document.getElementsByClassName('adsbygoogle'), function () {
            adsbygoogle.push({})
        })
    }
</script>

No matter how many google ads you have on the page, put ONE copy of the external js within the head of your page ... it's OK at the top since it's async.

Put the ins supplied by google where the ad is to appear.

At the bottom of your page, just before the end body tag, put the script to push the ad.

Now the ad will load after your page is complete !

If you want to add a second adsense ad on the page, do not repeat the adsbygoogle.js (one copy is enough) ... put the second where it is to be displayed ... add another push at the bottom of your page so it looks like this:

(adsbygoogle = window.adsbygoogle || []).push({}); (adsbygoogle = window.adsbygoogle || []).push({});

A Vanilla solution is to leave all your ad code as is, except to remove the script tag, and then add to your javascript

function loadGoogleAds() {
    var scriptTag = document.createElement('script');
    scriptTag.setAttribute('src', '//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js');
    scriptTag.setAttribute('type', 'text/javascript');
    scriptTag.setAttribute('async', 'async');
    document.body.appendChild(scriptTag);
}
window.addEventListener("load", loadGoogleAds);

Disclaimer: as with the other answers to this question it is assumed that Google does not disapprove of methods to improve page performance

Place the code for initiating the ad's at the bottom of the page just before the closing /body> tag

(This solution requires jQuery)

Remove the <script> tag from your code and add this to your javascript:

$(function() {
  $.getScript("//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js");
});

This will do an AJAX call to get the script, rather than using the async browser method. This should result in not having the loading indicator.

This is what I did, after noticing adsense slows down page loading/rendering:

first of all add this code to your <Body> tag:

<body onLoad="initialize_page();">

Now, put only one adsense script code, above the <HEAD> tag:

<script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

Remove adsense <script async src="//pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> from all of your adsense code(one copy at the header is enough).

Remove all (adsbygoogle = window.adsbygoogle || []).push({}); from your adsense code from your page. We will be using them over our initialize function.

To our initialize_page() function, add this code:

function initialize_page()
{
    (adsbygoogle = window.adsbygoogle || []).push({});//this is for the first adsense
    (adsbygoogle = window.adsbygoogle || []).push({});//this is for the second
    (adsbygoogle = window.adsbygoogle || []).push({});//this is for the third
}

This code is suitable for 3 adsense on your page. if you use only 2 or 1 adesnes, just remove (adsbygoogle = window.adsbygoogle || []).push({}); from the function respectively.
