Is my blog simply duplicate content of my authors' profiles?

[Brocberry]

www.example.com/blog

is the full list of blog posts by various writers. The list contains the title of each article and the first paragraph from the article.

In addition to /blog being indexed, each author's contribution list is being indexed separately. It's not a profile, really, just a list of articles in the same title & paragraph format of the /blog page.

So if /blog a list of 10 articles written by two writers, I have three pages:

/blog/author1 is a list of 4 articles

/blog/author2 is a list of 6 different articles

/blog is a list of 10 articles (the 4+6 from the two writers)

Is this going to be considered duplicate content?

What happens when you add a new article by Author3 ?

/blog/author1 is a list of 4 articles

/blog/writer2 is a list of 6 different articles

/blog/writer3 is a list of 1 article?

/blog is a list of recent 10 articles (the 1+4+6 from the two writers), /blog/page2 getting the 11th article ?

If this is the case, I would not worry too much about it. Homepage is set to recent articles and each author has it's own page. As you add/update more articles, more authors maybe, it's more different. It's a dynamic blog. A typical structure. I would not worry too much about it.

If you are concerned, you can set a noindex on your write pages.

The articles are posted by two people, so the the blog and author pages are quite similar.

If a third author wrote about "this-subject", I would have a page called:

example.com/this-subject

and urls /blog & /blog/author3 would each display the title and first paragraph from the /this-subject url

/blog would now have 11 article titles and first paragraphs

This is primarily a concern for one author blogs -- if your main blog index page has a nice mix of posts from various authors, and doesn't match a lot of content from the individual author pages, you will be fine.

Are you facing any ranking issues on your homepage / author pages ? Do you even want your author pages to rank ? Considering your answer, I'd suggest adding a noindex tag on your author profile pages, specially since you only have 2 authors.

From the CMS point of view, it is mainly published by one person.

I might ask a professional in the particular field to write an article about something related to my products and then post it as my brand, with an introduction about the author.
