Google+ comments (как было сделано у меня на сайте, сейчас использую disqus):

<div id="g-comments-id" style="width: 100%">
   <div class="g-comments"
      data-href="https://satin-pl.com/webnote/index.php?action=viewArticle&articleId=<?php echo $results['article']->id?>"
      data-width = "820"
      data-first_party_property="BLOGGER"
      data-view_type="FILTERED_POSTMOD">
   </div>
 </div>

<script type="text/javascript">
    window.___gcfg = {lang: 'ru'};
    document.getElementsByClassName('g-comments')[0].setAttribute('data-width', document.getElementById('g-comments-id').clientWidth);
    (function () {
        var po = document.createElement('script');
        po.type = 'text/javascript';
        po.async = true;
        po.src = 'https://apis.google.com/js/plusone.js';
