Volete davvero assicurarvi che i contenuti del vostro sito web WordPress vengano visualizzati al meglio su Facebook? Dovete aggiungere i metadati di Facebook Open Graph al vostro tema WordPress.
I metadati Open Graph forniscono a Facebook e ad altri siti di social media informazioni sui vostri post e pagine di WordPress e vi permettono di controllare come appaiono quando qualcuno li condivide.
In questo articolo vi mostreremo come aggiungere facilmente i metadati di Facebook Open Graph nei temi WordPress. Condivideremo tre metodi diversi, tra cui il metodo All in One SEO che usiamo noi di WPBeginner, in modo che possiate scegliere quello che funziona meglio per il vostro sito web WordPress.
Potete usare i link rapidi qui sotto per passare direttamente al metodo che vi interessa di più:
Metodo 1: Aggiungere i metadati Open Graph di Facebook con AIOSEO
All in One SEO è un popolare plugin SEO per WordPress utilizzato da oltre 3 milioni di siti web. Consente di ottimizzare facilmente il sito web per i motori di ricerca e per le piattaforme sociali come Facebook e Twitter.
Innanzitutto, è necessario installare e attivare il plugin gratuito All in One SEO. Per maggiori dettagli, consultate la nostra guida passo passo su come installare un plugin di WordPress.
Dopo l’attivazione, è necessario visitare la pagina All in One SEO ” Reti sociali. Qui è possibile inserire l’URL della propria pagina Facebook e di tutti gli altri social network.
Quindi, fate clic sulla scheda Facebook nella parte superiore della pagina e vedrete che Open Graph Markup è abilitato per impostazione predefinita.
È possibile fare clic sul pulsante “Carica o seleziona immagine” per scegliere un’immagine OG di Facebook predefinita se un articolo non ha un’immagine Open Graph.
Scorrendo verso il basso, è possibile personalizzare il nome del sito, la descrizione e altre impostazioni. Non dimenticate di fare clic sul pulsante blu “Salva modifiche” una volta terminato.
Dopo aver impostato i metatag Open Graph per tutto il sito, il passo successivo è aggiungere i metadati Open Graph per i singoli post e pagine.
Per impostazione predefinita, AIOSEO utilizzerà il titolo e la descrizione del post per il titolo e la descrizione di Open Graph. È inoltre possibile impostare manualmente la miniatura di Facebook per ogni pagina e post.
È sufficiente modificare il post o la pagina e scorrere fino alla sezione “Impostazioni AIOSEO” sotto l’editor. Da qui, passate alla scheda Social e vedrete un’anteprima della vostra miniatura.
Qui è possibile impostare l’immagine del social media, il titolo e la descrizione.
Basta scorrere verso il basso fino al campo “Fonte dell’immagine”. Si può scegliere di utilizzare l’immagine in evidenza, caricare un’immagine personalizzata o altre opzioni.
Metodo 2: Impostare i metadati Open Graph di Facebook con Yoast SEO
Yoast SEO è un altro plugin SEO per WordPress che può essere utilizzato per aggiungere i metadati di Facebook Open Graph a qualsiasi sito WordPress.
La prima cosa da fare è installare e attivare il plugin Yoast SEO. Per maggiori dettagli, consultate la nostra guida passo passo su come installare un plugin di WordPress.
Una volta attivati, i dati Open Graph di Facebook sono abilitati di default.
È possibile verificarlo andando su Yoast SEO ” Impostazioni e scorrendo giù fino alla sezione Condivisione sociale. Ora è possibile verificare che la caratteristica dei dati Open Graph sia abilitata.
è necessario andare in SEO ” Social e selezionare l’opzione ‘Abilitato’ in ‘Aggiungi meta dati Open Graph’.
È possibile salvare le impostazioni o continuare a configurare altre opzioni sociali di Facebook.
È possibile fornire l’ID dell’app di Facebook se si utilizza una pagina Facebook e gli insight. Potete anche modificare il titolo, la descrizione e l’immagine della vostra homepage Open Graph.
Infine, è possibile impostare un’immagine predefinita da utilizzare quando non è stata impostata alcuna immagine per un post o una pagina.
La versione Premium di Yoast SEO consente anche di impostare i metadati Open Graph per le singole pagine e post. È sufficiente editare una pagina o un post e scorrere verso il basso fino alla sezione “Yoast SEO” sotto l’editor.
Da qui è possibile impostare una miniatura Facebook per quel particolare post o pagina. Se non si imposta un titolo o una descrizione del post, il plugin utilizzerà il meta titolo e la descrizione SEO.
Ora è possibile salvare il post o la pagina e il plugin memorizzerà i metadati di Facebook Open Graph.
Metodo 3: Aggiungere i metadati Open Graph di Facebook con il codice
In genere è necessario copiare e incollare il codice nel file functions.php del tema. Tuttavia, consigliamo di aggiungere il codice utilizzando il plugin WPCode, che rende più facile e sicura l’aggiunta di codice personalizzato in WordPress.
WPCode dispone anche di una libreria di snippet di codice già pronti, tra cui uno per l’aggiunta di tag Open Graph di base, per cui bastano un paio di clic.
Innanzitutto, installare e attivare il plugin gratuito WPCode. Per maggiori dettagli, consultare la nostra guida su come installare un plugin di WordPress.
Dopo l’attivazione, è possibile andare su Code Snippets ” + Add Snippet dalla dashboard di WordPress.
Cercare lo snippet “Aggiungi tag Open Graph di base” nella libreria. Una volta trovato, passateci sopra e fate clic sul pulsante “Usa snippet”.
WPCode aggiungerà automaticamente il codice e imposterà l’header del sito come metodo di inserimento.
Dopodiché, è sufficiente attivare/disattivare lo snippet e fare clic sul pulsante “Aggiorna”. Il tema inizierà a mostrare i metadati di Facebook Open Graph nell’header di WordPress.
Se siete utenti avanzati, potete comunque copiare e incollare il codice sottostante nel file functions.php del tema.
Poiché è necessario modificare direttamente i file del tema, assicurarsi di eseguire un backup dei file del tema prima di apportare qualsiasi modifica.
//Adding the Open Graph in the Language Attributes
function add_opengraph_doctype( $output ) {
return $output . ' xmlns:og="http://opengraphprotocol.org/schema/" xmlns:fb="http://www.facebook.com/2008/fbml"';
}
add_filter('language_attributes', 'add_opengraph_doctype');
//Lets add Open Graph Meta Info
function insert_fb_in_head() {
global $post;
if ( !is_singular()) //if it is not a post or a page
return;
echo '<meta property="fb:app_id" content="Your Facebook App ID" />';
echo '<meta property="og:title" content="' . get_the_title() . '"/>';
echo '<meta property="og:type" content="article"/>';
echo '<meta property="og:url" content="' . get_permalink() . '"/>';
echo '<meta property="og:site_name" content="Your Site Name Goes Here"/>';
if(!has_post_thumbnail( $post->ID )) { //the post does not have featured image, use a default image
$default_image="http://example.com/image.jpg"; //replace this with a default image on your server or an image in your media library
echo '<meta property="og:image" content="' . $default_image . '"/>';
}
else{
$thumbnail_src = wp_get_attachment_image_src( get_post_thumbnail_id( $post->ID ), 'medium' );
echo '<meta property="og:image" content="' . esc_attr( $thumbnail_src[0] ) . '"/>';
}
echo "
";
}
add_action( 'wp_head', 'insert_fb_in_head', 5 );
Ricordarsi di aggiungere il nome del sito alla riga 17, dove è scritto “Il nome del sito va qui”. Successivamente, è necessario modificare l’URL dell’immagine predefinito alla riga 19 con uno dei propri URL dell’immagine.
Si consiglia di inserire un’immagine con il proprio logo, in modo che, se il post non ha una miniatura, venga estratto il logo del sito.
È inoltre necessario aggiungere l’ID dell’applicazione di Facebook alla riga 13. Se non si dispone di un’applicazione Facebook, è possibile rimuovere la riga 13 dal codice.

This is indeed helpful but SEO Yoast’s interface doesn’t look like this anymore. This needs updating.
WPBeginner Support
Thank you for letting us know that their interface has been updated, we will look to update it when we update the article

Thanks for the tutorial. I’ve been adding Open Graph in AIO SEO and I’m still surprised that AIO SEO tells me there isn’t one. I spent about half an hour on this before I found out that I had to click refresh again in the SEO evaluation so that the plugin would download the new WordPress settings and do a new SEO analysis. Such a simple thing and it took me so long.
Harry Goldhagen
Hello, thanks for the code snippet, I look forward to trying it. One question, will it then allow FB to pick up the featured image (is that the “thumbnail”?) and excerpt for each blog post, or will it just use the sitewide logo image designated in line 19? I’ve tried Blog2Social, but the posts lacked the featured image and excerpt and did not look good. Thanks!
WPBeginner Support
The code snippet should set your featured image to the featured image of the post.
Admin
Kiss Attila
Hi,
Awesome code. BUT, why it’s not changes og:url and og:image. I tried with a post with no image set as default. But checking it on fb debugger, it picks up my logo from the footer instead of getting the image I added in the og:image part.
Title is working it changed from the origin and I pasted og:description too. All the most important metas but image and url.
Why is that?
Thanks,
Atila
WPBeginner Support
Please ensure you’ve cleared any caching on your WordPress site as that is the most common reason it would not update to match the code.

hi how can i modify the code to add OG tags for custom post types i tried by changing this line code if ( !is_singular()) to if ( is_singluar( array( ‘post’, ‘publications’) ) ) but my website throw fatal error. can anyone please help thank you
WPBeginner Support
You should not need to modify the code to work with custom post types and it should work on them

Hello, i tried all the solution suggested still i miss some parameter to the schema:
A required field is missing: id
A required field is missing: price
A required field is missing: availability
Is there any solution via plugin or updating the function.php code?
WPBeginner Support
That would be markup for a product you are selling on your site and All in One SEO does have the option to add that markup to your products.

Does this also work for sms text message url previews or just Facebook?
WPBeginner Support
While not specifically for SMS messages, the markup helps with that as well.
Admin

If I use the Yoast SEO settings, will it take times for showing the perfect result in facebook share? Or will it start working within minutes?
WPBeginner Support
That would depend on your site’s caching and any caching on Facebook for how long it takes
Admin
Indranil Paul
I’m facing this problem in all social sharing sites.
WPBeginner Support
If it is not showing what you set on every social site, you would want to reach out to Yoast’s support and let them know to ensure there isn’t a problem with the plugin.

If you’re using Yoast to add the meta data, we would first recommend reaching out to Yoast to ensure that there aren’t any known issues.

Hello
Please can you advise when using a child theme – do i need to copy the parent theme functions.php and then add the above script to a newly created functions.php and upload it to the child theme folder OR do I just add the script to the parent theme functions.php
Thanks for reading Sadie
WPBeginner Support
Hi Sadie,
You can add it to either functions.php file.

How would I remove the “By …” from appearing on the card?
Currently we have an issue where it displays as: site-name | By site-name
We just want the first website name to appear and not twice.

All Good, But still one problem, How to add Facebook ID..After using this code, following Facebook ID message appears.
The ‘fb:app_id’ property should be explicitly provided, Specify the app ID so that stories shared to Facebook will be properly attributed to the app. Alternatively, app_id can be set in url when open the share dialog.
Eric Hepperle
I enjoyed this article, but in January 2018 this *manual code* option doesn’t appear to work completely. For instance, though I have verified that the default image property works, when I create a new post, I don’t see ANYWHERE a field where one can begin to edit “open graph (og)” metadata.
Suggestions? Thanks!
Mahesh Yadav
Thanks for such great information. But I have one question.
How helpful it is to add facebook graph meta data in our site..?
And if it is very much helpful, for what purpose, it is helpful..?

This plugin gave me a white screen of death, obviously a conflict with something or memory exceeded

What if I am wanting to change the thumbnail image not for the whole site, but just a page off my wordpress site : For example I’m trying to share an event page from my site and would like a unique, relevant thumbnail. Help?

Hey, I wanted to include Worpress SEO by Yoast but Im not sure if latest version is compatible with my version of Worpress (4.2.2) do you know if is safe to activate?
Thanks guys

Does my Facebook profile have to be public in order for my Facebook User ID to be good to use here?
Martin
I’ve added the code for manually adding this to my theme. However, things aren’t working. Does my profile have to be public in order for my Facebook user id to be accessible?
WPBeginner Support
Hi Martin,
Yes it would work.

Is this still valid for today? I tried it and works, but I noticed in the code the following: “xmlns:fb=”http://www.facebook.com/2008/fbml”‘;
Isn’t 2008 a little old? Is there a newer protocol we should be using today?
Wagner Lungov
Hello, thanks for posting. I remained with one doubt. I understood that the in each post is dynamically constructed by the functions you explained so well. What I can’t figure out is where the variables called by that function are defined and stored. When you put property=”og:type” content=”article”/, OK you are defining with a fixed string. But when you use: property=”og:title” content=”‘ . get_the_title() . ‘”, where is the function get_the_title() going to get it? How can I define before hand those values for each post in a way that the code will pick the right meta data for each parameter?
Jordan Carter
get_the_title() will get your post title. If you want to use something else, you could always get the value from a meta box. With the advanced custom fields plugin, it would be something like get_field(“my_field”), or with a regular WordPress custom meta field it would be get_post_meta($post->ID, “my_field”, true). See get_post_meta()
Jolanda
Nicely explained! I try to figure out where I can add the code in checking the size of the featured image, since FB needs a size with a minimum of 200px for both width and height, otherwise it will use another image from the post.
Any help would be great!
Mohsin Rafique
Nicely explained & works like a charm.

I’ve been trying to use Yoast to enable my meta data so I can use Rich Pins on Pinterest. I’ve done what this tutorial says, but Pinterest still won’t recognize my post. Is there another plugin I could try?
Michelle
I added the Yoast plugin and there is no social option. Please help me. I am at my wits end with this issue.
Brent Watkins
Same problem here.
Glenford
Once you have Yoast installed the look under SEO » Dashboard » Titles & Metas and under that is Social.
in Social you should Enable the “Add Open Graph meta data” in the Facebook tab.
Xavier
This option just isn’t there with v4.6 of the plugin.
Under SEO >> Dashboard, the tabs I have are: Dashboard, General, Features, Company info, Webmaster tools and Security. No mention of Titles & Metas or Social.
Is this because I haven’t set up a Facebook social profile? Surely this shouldn’t be needed just to be able to configure OG stuff!
WPBeginner Support
Hey Xavier,
First you would need to go to SEO » Features page and then click ‘Enable’ under ‘Show Advanced Settings Pages’ option. This will display advanced settings pages in Yoast SEO. For more details see our article on how to install and setup Yoast SEO.

I added social sharing to the search result template, so each excerpt has a share button BUT the meta data that is shared is messed up and uncontrollable with this, is there a way to make this work better when there are 20 reuslts on the same page with different meta description for each?

I’ve downloaded the Yoast plugin, and set it up for my home page, but when I enter the website on Facebook it still won’t show the image I’ve specified, or the text snippet I’ve written.
Also can’t find my Facebook URL using the link you provided, it just gives me an error…
I tried debug but it says Facebook pages can’t be debugged, and they have no cache.
Sooooo….nothing has worked so far!
WPBeginner Support
You need to enter your WordPress site URL in the debug tool.

I just wanted to thank you for this very thorough description on the process of connecting facebook to your wordpress page. I’ve been trying to do for days now following other sites and recommendations. This evening I came across your page from a google search and bam, it worked. Hooray! Thanks a lot.
Amanda Paul
Thanks for this info. It was really easy to follow. I uploaded the Yoast plugin and followed all the steps and saved but the thumbnail is still just a blank box. does it take some time to flow through? Do I need to log out and back in again to Facebook? or Wordpress?

me too – any help?

I have the same problem, and I cannot use FB debugger because i work in localhost…

this worked for me:
$metadesc = strip_tags(get_post_field(‘post_content’, $post->ID));
echo ”;
(my posts had a very short content)
Kim McCann
The following works by pulling from your excerpt. Just add under og:title
WPBeginner Staff
Check your page using Facebook debug tool
https://developers.facebook.com/tools/debug Usually checking a page with the debug tool refreshes the Facebook’s cache and you will be able to see the new image.
BK
Thank you for taking the time to reply. Will give it a shot!
BK
Thanks for this. I want to share link directly from my site using the social button. However, when I click on for example the Facebook share button, the image and the description is still using a previous information. Although I have updated the image and description using Yoast SEO and specifically customise the image and description for that post. May I know what did I do wrongly?
Naren Patel
Thank you very much, I really want this information.

Did you set a featured image? did you replace the default image URL in the code with your own image URL?
