I have ecommerce website with hundreds of products.
Client has changed the website url structure and parmalinks of whole website.
So, if I open old indexed pages from google it shows 404 error.
I want to remove all those pages. I know there are tool in webmaster but I want to do it all in once by removing multiple websites from google.

ie. in this there are hundreds of sub-products in this wholesale category and same with rings and other pages.

So, can any one please help me guide how to remove multiple products from google.

Go4Expert has also changed its URL structure and the best is to issue a 301 permanent redirect from old url to new url.
