question to the community
Do you have detailed case studies confirming that the implementation of OG markup affected the position of the site in the SERP?
The sites themselves can not be fired, they are just interested in the specifics - there are dynamics, there are no dynamics.

please
Do not send links to Wikipedia about Open Graph, that this is supposedly the standard from Facebook, what does SEO have to do with it. Yes, I know the story. Interested in case studies and results.

According to my observations, there is a small effect of markup on the position of the site. There is definitely an impact on the snippet, and hence on click-through. And as a result, behavioral factors change.
case is described in the blog.

Answer 1

On the screenshots you have connected "products and prices" or either schema.org.
And why would the OG markup affect the positions? Indirectly - perhaps, because. you serve your "product" in a normal wrapper, and not anyhow, hence, of course, attraction.
On one of the sites, I decided to make a dynamic cover, assembled from the uploaded image and the text (page title) superimposed on it, and later, I pushed the finished image into OG. It turned out pretty solid.
I stole this feature from mail.ru from their news sections.

Answer 2

it affects the tail, essno,
but due to abuses, there is not exactly the opposite picture, but Google’s abuse of the site’s infection, incorrect definition of topics, etc.
