Any reason why the blogger posts do not generate a snippet?

_For example_, on this blogger post, I paste a URL, and merely the URL appears:

> **[Transportes, os dados que os economistas não publicam](https://www.veraveritas.eu/2018/06/transportes-os-dados-que-os-economistas.html)**
>
> Não que acredite que numa ciência que se quer analítica e exata quanto possível haja matérias tabus, mas não deixa de ser interessante que em todas as soluções energético-económicas, em nenhuma delas com impacto mediático de relevo, observamos os...

But on Wordpress, normally, a snippet appears.

Which meta-info or HTML tags Discourse gets to generate a snippet?  
Which information shall one have in a blogger post, such that a sinipet is generated?

thank you

For testing we recommend using [Iframely](https://iframely.com/embed/https%3A%2F%2Fwww.veraveritas.eu%2F2018%2F06%2Ftransportes-os-dados-que-os-economistas.html).

A typical blog post will have [OpenGraph](http://ogp.me) tags in the head seaction, like:

```plaintext
<meta property="og:site_name" content="Discourse Blog">
<meta property="og:url" content="https://blog.discourse.org/2018/05/discourse-2-0-released/">
<meta property="og:title" content="Discourse 2.0 released!">
<meta property="og:description" content="We released Discourse 2.0 on May 31st, building on Discourse 1.9 from January. New Admin Dashboard We’ve completely redesigned the admin dashboard to show off your most relevant and essential community health metrics right at the top, as well as trending searches. Shared Drafts Staff can designate a category for shared drafts, and pre-compose topics that only other staff can see for review prior to posting.

Thanks a lot. Apologies to ask again after this time, but I’ve been around trying to [insert that on my blogger blog template](http://www.addthis.com/academy/how-to-add-open-graph-tags-using-blogger/)

Does it take time to fetch/update?

The tester you suggested [seems to fetch the code correctly](https://iframely.com/embed/https%3A%2F%2Fwww.veraveritas.eu%2F2014%2F04%2Fferrovia-ou-rodovia.html) but here the discourse still does not render the snippet.

> **[Ferrovia ou rodovia, o que é melhor para Portugal e para a Europa](https://www.veraveritas.eu/2014/04/ferrovia-ou-rodovia.html)**
>
> Tem-se debatido muito sobre, se Portugal e os restantes países europeus, devem ou não reinvestir na ferrovia em comparação com os investimentos substanciais que se fizeram nas últimas décadas em rodovia, e muito particularmente em autoestradas....

Thanks, finally I solved everything.

For blogger, I used this code, which I inserted right before the tag `</head>` in the blogger’s template

```plaintext
    <!-- OpenGraph starts-->
    <meta content='article' property='og:type'/>
    <meta expr:content='data:blog.title' property='og:site_name'/>
    
	<!-- Title and URL -->
    <meta expr:content='data:blog.pageName' property='og:title'/>
    <meta expr:content='data:blog.canonicalUrl.https' property='og:url'/>
		
    <!-- Image -->
	<b:if cond='data:blog.postImageThumbnailUrl'>
		<meta expr:content='data:blog.postImageThumbnailUrl' property='og:image'/>
    <b:elseif cond='data:blog.postImageUrl'/>
    	<meta expr:content='data:blog.postImageUrl' property='og:image'/>    
	<b:else/>
    	<meta content='YOUR_LOGO_URL' property='og:image'/> 
    </b:if>

	<meta expr:content='&quot;pt_PT&quot;' property='og:locale'/>

    <!-- OpenGraph ends-->

```

The `og:description` is not fetched inside `<head>` since the variable `data:post` is not available in `<head>`. You must add in the template right after the line `<data:post.body/>` the following line:

```plaintext
<meta expr:content='data:post.snippet' property='og:description'/>

```

If you want a costumized snippet you may use this instead

```plaintext
<meta expr:content='snippet(data:post.body, { length: 150, links: false, linebreaks: false })' property='og:description'/>

```

now it seems to work smoothly, here’s a test 🙂 (please, it’s not spam, it’s _merely_ a test showing that it does work here in discourse)

and btw, why there’s no favicon when all the favicons are enabled?
