Control over og:type

Hi,

We noticed over time that many blog posts shared on Facebook gets the following details added to their Facebook feed post: image, title, and description.

However, when sharing a Squarespace blog post on Facebook we only get the image and the title. No description.

It took us a while to understand the problem arise because Squarespace put og:type as "article" ...which I guess is technically ok. However, many other websites are aware of that limitation/bug and changed their og:type to "website" so FB users can get the first line of content (description).

This first line is critical to get people attention and give a sense of an actual blog post, not just a flat out link outside of FB. The visual and the impact on perception is major.

Is there any way we can get control over this? 

First attachment have no first line (og:type "article") the other yes (og:type "website" even though it's a blog -- not a competitor, just for sake of demonstrating).
