I have a well seo-d website, running on the top serps for many keywords / phrases.
Now I want to add a knowdledge base (KB) about the topic.
Some of the current articles (not in the Knowledge base) will overlap in terms of subject.
Obviously the KB will be filled with unique text, but the titles and content could overlap (I wont copy anything).
Will / can this hurt my SEO?
How should I proceed?
I dont want to loose rankings on my current articles, but I want to start ranking on direct questions and "rich snippets" in google.
