How to tell Facebook which div is the “content” one? (for links summary)

问题

I have a small blog hosted on blogger.com

I don't understand why, when people like or share a blog post on Facebook, the real content is never fetched as a summary.

For example, for this post, the summary is the small "about me" that I placed on the sidebar, while on this other post, the summary is the first comment.

It's weird, what I can do? There is a way, for example a class, to indicate the main content div?

回答1:

You need to implement the Open Graph tags for Facebook into your blog.

回答2:

Implement opengraph protocol on Blogger. It marks the post title, description, image, author etc using its markup language. Refer this tutorial on Implement ogp on Blogger
