Hi everyone, I manage an e-commerce site. I want to solve this problem: In my sites there are many shop which sell same product. Titles and description come automatic. How can I solve the duplicate problem.
What do you mean by "many shop on one e-com site" ? Do you mean, several pages featuring the same product?
How did you come to this situation? Is, was there a legitimate reason? Or a mistake?
To solve duplicate problem, you can set 301 redirects from all these identical pages, to just a unique one. Or, if there is a legitimate reason to have several page featuring the same product, you can use canonical url.
Do you have a bug which is duplicating existing products (adding new ones) instead of "updating" them, or is it because different users are adding the same product? If the latter then you need to write a plagiarism filter that takes random snippets and looks for them in other product submissions.
