404 errors – Product sites


in our shop (apparel) hundreds of 404 mistake pages/blank Links have actually collected throughout the years. These are – as anticipated – primarily filter web pages and also Links of no more existing items.
My concern is: exactly how do I obtain these Links out of the search engine result? Most likely, the most effective method to address the filter web page trouble is to utilize robots-meta-tag.

Yet what regarding the old item Links specifically web pages with the items eliminated from the array – establishing 10 000 such web pages to “noindex” or reroute them to the web page by hand/ by hand?

Given That it would certainly be a job of weeks or months – maybe there are various other alternatives/ways …

Thx and also kind relates to.
