Mempercepat Loading Blog atau Website Blogger, Wordpress, Joomla Semuanya

Cara mempercepat loading blog menggunakan teknik lazyoad image dan lazyload adsense, kedua cara ini mampu mempercepat loading blog hingga mencapai 90 lebih pada tabel test speed insight google. Buat kalian yang sudah bergabung dengan periklanan adsense dan iklan adsense sudah tayang pada blog kalian tentu blog akan terasa semakin berat setelah memasang iklan adsense, lalu bagaimana solusi mengatasi blog lambat? berikut caranya

Mempercepat loading blog yang telah menampilkan iklan adsense menggunakan lazyload for adsense, trik ini mengambil dari sourc scroll jadi buat kalian yang ingin menggunakan trik ini tidak diperbolehkan memasang iklan above atau bottom ya. berikut kode lazyload adsensenya kalian copy kemudian paste sebelum tag penutup body atau sebelum kode </body>

<script>
//<![CDATA[
var lazyadsense = false;
window.addEventListener("scroll", function(){
if ((document.documentElement.scrollTop != 0 && lazyadsense === false) || (document.body.scrollTop != 0 && lazyadsense === false)) {

(function() { var ad = document.createElement('script'); ad.type = 'text/javascript'; ad.async = true; ad.src = 'https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js'; var sc = document.getElementsByTagName('script')[0]; sc.parentNode.insertBefore(ad, sc); })();

    lazyadsense = true;
  }
}, true)
//]]>
</script>

Setelah kalian memasang kode lazyload diatas cek semua kode iklan kalian dan hapus kode berikut <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script>

Jadi setiap pasang kode iklan kalian wajib hapus kode <script async src="https://pagead2.googlesyndication.com/pagead/js/adsbygoogle.js"></script> dan yang dipasang hanya kode seperti ini 

<ins class="adsbygoogle"
     style="display:block"
     data-ad-client="ca-pub-XXXXX"
     data-ad-slot="XXXXXX"
     data-ad-format="auto"
     data-full-width-responsive="true"></ins>
<script>
     (adsbygoogle = window.adsbygoogle || []).push({});
</script>

Mempercepat loading gambar blog menggunakan lazyload image caranya pasang kode berikut sebelum penutup kode head atau sebelum kode </head>

Kemudian untuk mengaktifkan lazyload pada tiap gambar silahkan tambahkan class pada kode pemanggil gambar, contoh:

<img class="lazyload" data-srcset="http://www.simbahbuyut.com/gambar.jpg" />
