For images to appear large as in the second example mentioned in your question, use images that have at least 1200 x 630
pixels for better display on high resolution devices. The minimum size required for images to appear large in this way is 600 x 315
pixels. And the minimum size required for the og:image
is of 200 x 200
.
You can read more about the topic - og:image
here at this link
However I noticed that the problem of the image appearing small was due to a lack of update, as after having inspected the link on Object Debugger
i saw that the image appears large after updating the link with Object Debugger.
On the description does not appear, try changing the og:description
as follows.
Exchange the current code:
<b:if cond='data:blog.metaDescription != ""'>
<meta expr:content='data:blog.metaDescription' name='og:description'/>
</b:if>
To the next:
<b:if cond='data:blog.metaDescription'>
<meta expr:content='data:blog.metaDescription' property='og:description'/>
<b:else/>
<meta expr:content='"Ler artigo sobre " + data:blog.pageName + " em " + data:blog.title + ""' property='og:description'/>
</b:if>
Basically what this is going to do is take the meta description
if it exists and display it as og:description
, but if there is no meta description
available, then the text Ler artigo sobre ...
will be implemented as og:description
instead.
Meta description
in Blogger
To activate the meta description
you have to go up:
Definições > Preferência de pesquisa > Meta tags > Descrição
Click edit.
And the following shall appear:
Add Meta description
to individual publications
Simply edit your post or page and look for the option Description of the Research, and this is where we will add the description of each page that will now also be displayed as og:description
to Facebook.
