What is the most reasonable SEO way to link an organization's website with a group in a social network?

Question

Facebook

There is a certain company whose employees have created a group on FACEBOOK and, at intervals of several times a week, post there photos of the work process, notes about it, and sometimes even thematic articles. So all this is liked and reposted not only by employees, but also by customers who willingly subscribe to the group and repost from it, and their friends ...
... in general, quite a lively group that is well sought after and brings new customers,
and there is a business card website originally made “to be”, advertising from Yandex and Google leads to it, and it’s even searched a little there :-)
So I thought that it’s not good to disappear, it would be necessary to somehow display the movement from the social network on the site , because it would be at least not without interest to a potential client.
But what is the smartest way to do this? not in a technical sense, but from the point of view of SEO, maybe it makes sense to just take posts from the group to the news feed of the site, so that there would be many pages with texts, photos, H1 and titles and without any visible connection with fb? or vice versa, embed a Facebook feed into the site?

Answer 1

"H1 and titles and without any visible connection with fb" - it is!
Each news is a separate page.
You can add a link: "Read on our site" in Facebook posts.
On the site, these links (and back links to posts in FB) - do not display, leave only the widget: "Share/Share".

Answer 2

Offtopic, Dmitry. In answer to my question about what physics should do in IT, you mentioned digging in the direction of stock and currency markets. Can you suggest forums, books, authors on the topic? Best regards, Georgiy

In addition to links to groups on the site itself, you can also specify the organization's official group in Yandex.Directory.
