Edgar's Preview Tab shows you what your Facebook posts will look like before you publish them.  If you have selected a Facebook account and included a link in the text of your post, a Facebook Link Preview will be generated.

A Link Preview is the clickable box that contains an image from your link, the title of the link, and a short description of the content. 

You can publish a Facebook post with a Link Preview, with an uploaded image, or as text only. See the following example posts:

Post with a Facebook link preview: 

You can see the text of your post appears at the top. The image pulled from the link by the preview is in a clickable box with the title and description from the website below it.

Post with an uploaded image:

If you upload an image to your post in Edgar, the post will publish as a photo on Facebook with your accompanying text.

Post with the Facebook Link Preview Turned Off and No Uploaded Image

Turning off the Facebook Link Preview will result in a text-only post.

How do I edit or remove Facebook Link Previews?

To turn a Facebook preview off, just click the X at the top right of the preview box:

If you'd like to change which link from the text of your post is being previewed, you can do so by editing the link in the link preview box: 

For example, if you have two links in your post and Edgar is currently previewing the second link, you can edit the link in the preview box to change it to the first link.  Or you can specify an entirely different link than those in your text.

How do I create or edit a Facebook Link Preview?

Facebook generates link previews automatically based on the meta tags in the code of the website you're linking to.  Specifically, the following og:tags should be included in the meta data on your website:

og:image
og:image:height
og:image:width
og:title
og:description

Don't worry!  That's not as code-y or difficult as it may sound.  These tags can usually be controlled with a simple plugin such as Yoast SEO.

Facebook’s New Link Previews: What You Need to Know About Creating Your Own

If you are not the owner of the website you are linking to and the site does not have the meta tags necessary to generate a preview, there is currently no way to alter a link preview except by bringing it to the attention of the website's owner so they can update their meta tags. 

However, rather than using a Facebook Link Preview, you can always upload an image to your post in Edgar or remove the Facebook link preview to send a text only post.

*Note: Facebook has an 8MB limit on images included in previews. If an image on your website is over 8MB, it will not be included in a link preview.

What if Edgar says he can't find a Facebook Preview for my link?

Edgar's previews are only approximations of what Facebook will display. Facebook will check your link and create the link preview at the time the post is published.  

So, even if Edgar can't show you a preview right now, Facebook will still display one based on the meta data on your website.

And you can always see exactly what Facebook will show in a preview by using their link preview tool.

There are a few reasons why Edgar may not be able to display a Facebook preview for your link. Check out some of the common issues below:

Server error

Edgar may have received a server error from the website, likely due to site maintenance or another issue on the website's end. In most instances, these errors are temporary. 

SSL error

If your URL is correct and there are no current server issues, Edgar may be receiving an SSL error from the site. The website will not allow a preview to be pulled due to a firewall or security bot. Give another link from the same domain a try. If Edgar is still unable to pull a preview, this is likely the case. 

But don't worry.  Facebook will still display a preview when the post is published.  See what that preview will look like using their link preview tool.

Missing image, title, description, or other error

Run the link through Facebook's link preview tool to see what Facebook itself is able to pull.
 
If necessary information (such as og:image, og:title, og:description tags) are missing from the page, Facebook will show you warnings. These tags must be present on the website for a preview to be generated. Example warnings may look like this:
