Welcome to the Q&A Forum

When I visit the duplicate URLs, for example http://www.ebids.com.pk/store/fashion-point/?category_name=spare-parts-accessories&parent_id=3708&page=store_about, I don't get redirected - the URL stays the same. It looks like these are different tabs within the section of the seller Fashion Point - and both the title tag and content looks the same for all of them. For the URLs that are top-level tabs, like &page=store_about, or &page=company_policies, etc, I would do 2 things: Update the title tag to say something like "About Fashion Point" or "Fashion Point's Company Policies." This will take care of a duplicate title tag problem. Encourage, the people behind the Fashion Point account, (and probably all accounts), to fill out all of the tabs, so there's actual About, Company Policy, etc. content there - then the content will actually be different, so you won't get duplicate content problems. It might be a good idea to require that those sections are filled out before making the storefront public for a user, that way potential buyers will have more information about who they're buying from, and and the empty sections won't cause duplicate content problems.
