Welcome to the Q&A Forum

Yes that was the question, thank you. It is correct that for example 1 sub-category with the exact same list of products appears in 2 differents categories (but with a unique URL). So as you say in the second part of your first paragraph I should merge them or 301 redirect one of the categories to the other. If I understood your answer right, would it be better to choose 1 category (let's call it category1) as a "father" for this sub-category ? And maybe create a 301 redirection link for this sub-category that would be present in the second category (category2) ? Thank you, Max

Hello, I'm getting back to you about a point in your answer : "So you have to make clear that it is not 90% branded traffic , it should be more unbranded keywords.  In this case - before I would do anything, I would try to figure out why subfolder 2 is ranking for these terms and why subfolder 1 is not." I understood and one of the main Keywords is "muebles" (Furniture in english) but the pages are really similar. Except for the basic "Title, Meta, H1, etc" are there others characteristics or feature I should look into ? Thank you Maxime
