What pages of the site are considered duplicates for search robots?
Here is an example of a website. Informational portal. There is a main page on it, articles are immediately open but half. There is also a second page called blogs - there are the same articles but they are displayed in lines. When you click on "home" - read the entire article - the article opens and when you click on the "blogs" on the line of the article - the same article opens. Is this a duplicate? That is, there is one article, and there are two methods of getting into it. If this is not a duplicate, how do search robots relate? Normal or bad?
