By default, the Custom Facebook Feed plugin loads your Facebook feed using PHP on the server side so that they’re embedded into your page source code for SEO purposes. The only disadvantage of this is that your web page won’t display until the Facebook posts are loaded from Facebook (or from the plugin cache). If you’re requesting a lot of posts (or using the Multifeed extension to make a lot of requests) then this can cause an increase in your page load time.
1) Create a new blank page in WordPress and add your Custom Facebook Feed shortcode to it. This will be used to house your feed which will be then be loaded into your actual page.
2) Go to the page editor for the page where you want to display the feed, click on the ‘Text’ tab in the editor, and replace the existing shortcode with the following:
<div id="cff-load" style="text-align:center">Loading...</div> <script>jQuery('#cff-load').load('http://yourwebsite.com/page .cff-wrapper');</script>
3) Replace the URL in the script above with the URL to the new page that you set up
