Load Disqus on Scroll Using JavaScript :
Load Disqus comments when visitor scroll down page to comments with Ajax. Page speed plays crucial role in search engine rankings, to amend your website speed even more, you need to display Disqus comments on scroll down or on click button event demand base.
Loading Disqus comments on demand improves your page speed, but the number of comments will decrease. Which one you prefer Speed or Comments?, It's completely your choice. In our point of view, Page speed is more important than any other factor. Because the user doesn't want to stay on slow speed websites.
By default Disqus loads comments asynchronously,which is great sign to page speed.Add the below JavaScript code to your theme file.
$(function(){
var disqus_div = $("#disqus_thread");
if (disqus_div.size() > 0 ) {
var ds_loaded = false,
top = disqus_div.offset().top,
disqus_data = disqus_div.data(),
check = function(){
if ( !ds_loaded && $(window).scrollTop() + $(window).height() > top ) {
ds_loaded = true;
for (var key in disqus_data) {
if (key.substr(0,6) == 'disqus') {
window['disqus_' + key.replace('disqus','').toLowerCase()] = disqus_data[key];
}
}
var dsq = document.createElement('script');
dsq.type = 'text/javascript';
dsq.async = true;
dsq.src = 'http://' + window.disqus_shortname + '.disqus.com/embed.js';
