What impact does posting duplicate blog posts have on Google search?

Besides blog posts, if you post content you've written for a company or community to various other places, how does that affect Google search?

Many people wonder, "Is it better to only post my writing on my blog? What if someone else plagiarizes it? Or is it okay to post it on a community and my blog?", "I want as many people as possible to read my writing..."

These are common practices. For instance:

• Media company A copies 90% of a blogger's post with permission, adding comments or citing the source.
• Person B copies a post from Blog A and pastes it onto Blog B.
• Person C posts the same content on a community and their blog.
• Company D runs a blog and posts the same content on a community and a partner media company.

Yes, when you think about it, this happens quite a lot, doesn't it? Of course, you might only have read it in one place. However, from the perspective of the writer, they want their content to be seen in many places and read by many people, so whether they realize it or not, it's common practice to post it in multiple places.

So, what about Google Search?

Will having duplicate content negatively impact search visibility, resulting in a penalty? Will all the duplicate posts be displayed in search results? Or will only one of the duplicate posts be displayed?

According to a Google Search Advocate,John Mueller, in aninterview, part of a section (point 4) can be summarized as follows:

Duplicate content is not a negative ranking factor.
Duplicate content does not negatively affect a site's search ranking. Google handles this by displaying one version of the content and ignoring the others.
"So, if you have the same content on multiple pages, we won't necessarily show all of them. We'll pick one to show. So, it's not that there's a negative signal associated with that. In many cases, having a certain amount of shared content across a few pages is perfectly normal."

This is what he says.

In other words, "Just because the same content exists on multiple domains doesn't mean it's a negative factor for Google Search. It's quite normal and common for this situation to occur. Therefore, only one of the duplicates will be displayed in search results."
