In a website with user generated content, I provide an author bio under every article on the site.
The author bio will be the same under every article the same author wrote. For some authors, the author bio is no longer then a couple of sentences, but for some descriptive writers, it is a good 100 words. These 100 words get repeated in almost 15 pages, some of them without substantial original content (such as haikus).
Will this lead to duplicate content issues?
