Quer ter certeza de que o conteúdo do seu site WordPress ficará ótimo no Facebook? Você precisa adicionar os metadados do Facebook Open Graph ao seu tema do WordPress.
Os metadados do Open Graph informam ao Facebook e a outros sites de mídia social informações sobre seus posts e páginas do WordPress e permitem que você controle a aparência deles quando alguém os compartilha.
Neste artigo, mostraremos a você como adicionar facilmente metadados do Facebook Open Graph em temas do WordPress. Compartilharemos três métodos diferentes, incluindo o método All in One SEO que usamos na WPBeginner, para que você possa escolher o que funciona melhor para seu site WordPress.
Você pode usar os links rápidos abaixo para ir direto ao método que mais lhe interessa:
Método 1: Adicionar metadados do Facebook Open Graph com o AIOSEO
OAll in One SEO é um popular plugin de SEO para WordPress usado por mais de 3 milhões de sites. Ele permite que você otimize facilmente seu site para mecanismos de pesquisa, bem como para plataformas sociais como Facebook e Twitter.
Primeiro, você precisa instalar e ativar o plug-in gratuito All in One SEO. Para obter mais detalhes, consulte nosso guia passo a passo sobre como instalar um plug-in do WordPress.
Após a ativação, você precisa visitar a página All in One SEO ” Social Networks (Redes sociais ). Aqui, você pode inserir o URL da sua página do Facebook e de todas as suas outras redes sociais.
Em seguida, clique na guia Facebook, na parte superior da página, e você verá que a marcação do Open Graph está ativada por padrão.
Você pode clicar no botão “Carregar ou selecionar imagem” para escolher uma imagem padrão do Facebook OG se um artigo não tiver uma imagem do Open Graph.
Se você rolar a tela para baixo, poderá personalizar o nome do site, a descrição e outras configurações. Não se esqueça de clicar no botão azul “Salvar alterações” quando terminar.
Agora que você definiu metatags do Open Graph em todo o site, a próxima etapa é adicionar metadados do Open Graph para posts e páginas individuais.
Por padrão, o AIOSEO usará o título e a descrição de sua postagem para o título e a descrição do Open Graph. Você também pode definir manualmente a miniatura do Facebook para cada página e publicação.
Basta editar o post ou a página e rolar para baixo até a seção “Configurações do AIOSEO”, abaixo do editor. A partir daí, alterne para a guia Social e você verá uma visualização da miniatura.
Você pode definir a imagem da mídia social aqui, bem como o título e a descrição.
Basta rolar a tela para baixo até o campo “Image Source”. Você pode optar por usar a imagem em destaque, carregar uma imagem personalizada ou outras opções.
Método 2: Definir metadados do Facebook Open Graph usando o Yoast SEO
OYoast SEO é outro plug-in de SEO para WordPress que você pode usar para adicionar metadados do Facebook Open Graph a qualquer site do WordPress.
A primeira coisa que você precisa fazer é instalar e ativar o plug-in Yoast SEO. Para obter mais detalhes, consulte nosso guia passo a passo sobre como instalar um plug-in do WordPress.
Uma vez ativados, os dados do Facebook Open Graph são ativados por padrão.
Você pode verificar isso acessando Yoast SEO ” Configurações e rolando para baixo até a seção Compartilhamento social. Agora você pode garantir que o recurso de dados do Open Graph esteja ativado.
você precisa ir para SEO ” Social e selecionar a opção “Enabled” (Ativado) em “Add Open Graph meta data” (Adicionar metadados do Open Graph).
Você pode salvar suas configurações ou continuar e configurar outras opções sociais do Facebook.
Você pode fornecer um ID de aplicativo do Facebook se usar um para sua página do Facebook e insights. Você também pode alterar o título, a descrição e a imagem da meta-página inicial do Open Graph.
Por fim, você pode definir uma imagem padrão a ser usada quando nenhuma imagem for definida para um post ou uma página.
A versão Premium do Yoast SEO também permite que você defina metadados do Open Graph para posts e páginas individuais. Basta editar um post ou página e rolar para baixo até a seção “Yoast SEO” abaixo do editor.
A partir daí, você pode definir uma miniatura do Facebook para essa postagem ou página específica. Se você não definir um título ou uma descrição do post, o plug-in usará seu metatítulo e sua descrição de SEO.
Agora você pode salvar seu post ou página, e o plug-in armazenará os metadados do Facebook Open Graph.
Método 3: Adicionar metadados do Facebook Open Graph usando código
Esse método normalmente exige que você copie e cole o código no arquivo functions.php do seu tema. No entanto, recomendamos adicionar o código usando o plug-in WPCode, que torna mais fácil e seguro adicionar código personalizado no WordPress.
O WPCode também vem com uma biblioteca de snippets de código prontos, incluindo um para adicionar tags básicas do Open Graph, portanto, são necessários apenas alguns cliques.
Primeiro, instale e ative o plug-in gratuito WPCode. Para obter mais detalhes, consulte nosso guia sobre como instalar um plug-in do WordPress.
Após a ativação, você pode ir para Code Snippets ” + Add Snippet no painel do WordPress.
Procure o snippet “Adicionar tags básicas do Open Graph” na biblioteca. Depois de encontrá-lo, passe o mouse sobre ele e clique no botão “Usar snippet”.
Em seguida, o WPCode adicionará automaticamente o código para você, além de definir o cabeçalho de todo o site como o local do método de inserção.
Depois disso, tudo o que você precisa fazer é alternar o snippet para “Active” (Ativo) e clicar no botão “Update” (Atualizar). Seu tema agora começará a exibir os metadados do Facebook Open Graph no cabeçalho do WordPress.
Se você for um usuário avançado, ainda poderá copiar e colar o código abaixo no arquivo functions.php do seu tema.
Como isso exige que você edite diretamente os arquivos do tema, certifique-se de fazer backup dos arquivos do tema antes de fazer qualquer alteração.
//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 );
Lembre-se de adicionar o nome do seu site na Linha 17, onde está escrito “Your Site Name Goes Here”. Depois disso, altere o URL padrão da imagem na linha 19 com um de seus próprios URLs de imagem.
Recomendamos que você coloque uma imagem com seu logotipo ali, de modo que, se a postagem não tiver uma miniatura, ela puxará o logotipo do seu site.
Você também precisa adicionar seu próprio Facebook App ID na Linha 13. Se você não tiver um aplicativo do Facebook, poderá remover a Linha 13 do código.

This is indeed helpful but SEO Yoast’s interface doesn’t look like this anymore. This needs updating.

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.

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?

While not specifically for SMS messages, the markup helps with that as well.

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

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.

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

Hi Sadie,
You can add it to either functions.php file.

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

Does my Facebook profile have to be public in order for my Facebook User ID to be good to use here?

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?

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’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!

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?

this worked for me:

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!

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?
