Hi I just learned that my site is not having a meta tag for my facebook page.
I think I need to add this
But where? simply in the body of my index page or in general settings?
Ideas?
Yoast says; App_id should be ignored:
What does (did) the fb:app_id tag do?
The short answer
The simple answer is, “nothing”. You can ignore the warnings in the Sharing Debugger tool.
The longer answer
The longer answer is that the fb:app_id tag used to be part of Facebook’s ‘Domain insights‘ product. When users ‘liked’ your content (using an embedded like button on your webpage), the app_id value let Facebook know which Facebook Page should be able to see and access the relevant statistics.
The Domain Insights product no longer exists, though. The analytics capabilities that the fb:app_id tag provided are now part of Facebook’s Analytics platform, and require you to install a Facebook Pixel instead of a fb:app_id meta tag.
Facebook starting closing the Domain Insights platform in 2016, and replaced it with Facebook Analytics
You can read more about Facebook’s retirement of Domain Insights in this article.
Older versions of the error message also describe how the app_id tag was used attribute interactions with ‘stories’ would be correctly attributed. Like Domain Insights, Facebook’s support for Open Graph Stories was ended (in this case, in 2018).
“Specify the app ID so that stories shared to Facebook will be property attributed to the app.”
You can read Facebook’s announcement for ending their support on this help page.
With the removal of Domain Insights and Open Graph Stories, the fb:app_id meta tag is no longer used anywhere in Facebook’s ecosystem.
We’re hopeful that the Sharing Debugger will be updated to remove this warning.
We removed fb:app_id from Yoast SEO
Yoast SEO used to provide a field which allowed users to add a fb:app_id value. When that was set, we would output a meta tag on each page, which looked something like <property="fb:app_id" content="12345678">. We removed this in version 15.5.
tSetting your Facebook App ID in Yoast
Removing this was a long-overdue change, as the tag had long since been unsupported. Additionally, obtaining an app_id value was complex and convoluted (involving creating a Facebook application, and linking it to your website). Our controls, the tag itself, and Facebook’s app creation process lead to a lot of user confusion, and a lot of support overhead for us.
The Yoast SEO plugin still manages and outputs the rest of your open graph meta data, though. It’s only the fb:app_id tag which we’ve removed.
How to remove the warning
Whilst we’re confident that the ‘missing fb:app_id warning’ isn’t something that people should worry about, we recognize that some users might be uncomfortable seeing ‘errors’ in the Sharing Debugger tool. If you’re still concerned about the message, you’ll need to ‘fix’ it by (re)introducing an fb:app_id tag.
It’s our recommendation that you don’t follow these steps, and that no action is needed – despite the warning in the debugging tool.
Adding the fb:app_id tag (back) in
Since we completely removed support for the tag in Yoast SEO, you’ll need to use another approach to add it into your theme. Because we already output other open graph tags (like og:title and og:description), we don’t recommend another another plugin to reintroduce the fb:app_id tag. That’s likely to mean that you have duplicate open graph tags, which can lead to real warning and errors.
Instead of adding a plugin, we recommend that you add the tag via your theme’s functions.php file, or via your own custom plugin. You can use the following code as an example; though don’t forget that customizations to a theme may be overwritten if not handled properly (read more on preventing this by using a child theme).
function my_custom_function_name() {
$app_id = 966242223397117;
$tag = '<meta property="fb:app_id" content="%d" />';
echo sprintf($tag, $num);
}
add_action( 'wp_head', 'my_custom_function_name' );
Using Facebook’s “default APP ID”
The $app_id value in our example above (966242223397117) is Facebook’s “default APP ID”. This can be used by any website as a default, and will remove the error in the debugger.
If you have a Facebook app, you can replace that value and use your own application ID.
