Where to publish an article first: social network, blog or website?

Question

Content

There was nothing to do and decided to create 3 resources at once: a website, a blog and a group on a social network.
But I immediately got confused: where should I publish articles earlier from the listed ones? How will the search engine react to the appearance of the same article in three places: in terms of authorship, uniqueness?
Who will tell?

Answer 1

Select one main thing and publish there first.
It's better if it's a blog. (By the way, how does your site differ from a blog?!)
And on all the others - publish 30 minutes after sending the ping to the PS when publishing new content.
1. Posting content to the server
2. Creating a link to the publication (make the content available via the link, BUT DO NOT DISPLAY IN THE FEED! as a new article YET!)
3. Ping in the PS of this link.
4. Waiting for 30 minutes (and/or checking that a search robot visits this link).
5. Publication of the article (in the feed) for public reading.
