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?
Author bio on all pages - is it duplicate content?
seo;duplicate content
Theoretically, it can be considered as duplicate content but in practice, I don't think it can penalize your site on SEO-wise.To minimize the risks:for pages with thin content (I think about Haiku), ask your users more content about it (for example explaining where the Haiku comes from, why it has been created, in which case it can be useful to remember it, etc.)ask your users to use/write a short and condensed version of their bio (for example 3 sentences max)
