Facebook has provided a no-cost way to allow you to feature Facebook posts on any website. It’s called the Page Plugin.
Go to the link above, and follow the prompts to set up the plugin for your site. In the field provided, enter the URL for your Facebook page.
Use the additional fields and checkboxes to customize the plugin, and view the results in the preview below. When you are satisfied with the results, click on “Get Code” below the preview.
In the popup that appears, choose the “IFrame” tab and copy the code that appears in the gray box.
Once you have copied the code for your plugin, go to your site. Insert an Embed element from the Standard element library. If you are replacing an element that already exists on your page you should delete the old element first.
Once the element is on the page, edit the Settings and paste your code into the field provided.
Save the element and publish the page.
