Say that you create one article about "How to run a race in New York" and then you create another article about "How to run a race on Boston" (and more articles for other cities). Most of the content that these articles need is not specific to the city, and could therefore be used in both articles (around 90-95% of the articles could be kept the same). Is it then fine to reuse the same content in both articles, or does the content need to be reworded for Google to rank it well?
I think many instinctively would say that it's better to reword the articles to get as much "unique content" as possible on the website. However, from a user perspective this rewording does not add any value. The question is, is Google smart enough to understand this and rank the articles just as well even if I do not reword to articles? Google has also claimed that there is no such thing as duplicate content on the same website.
Does anyone have real experience with reusing content, and if so, how did it go? Have you seen any case studies on the subject?
