Hi Everyone,

I have a question regarding a problem with e-commerce URL.

When a user enters a search query on the e-commerce website a custom URL is generated, this URL is been crawled by Google and shows in Google Webmaster tool as 'URL Not Found' or 'Unreachable'.

How can we prevent this URL's generated by search to reflect in webmaster tool as 'Not Found'. I can't keep on removing it every time and forever. I want a permanent solution that can prevent these URL from Google.

Looking forward for your answers!
