how can i stop google indexing pages with urls ending with date and time

I have a website with some pages like

• www.xyz.com/product1
• www.xyz.com/product2
开发者_开发知识库

and www.xyz.com/product1/date which can be dynamic as what user searches.

Current google is indexing

• www.xyz.com/product1
• www.xyz.com/product2
• www.xyz.com/product1/date

I dont want google to index www.xyz.com/product1/date urls....

Maybe writing a proper robots meta tag:

• HTML spec

You might be able to do what you want with a robots.txt at your website root directory

User-agent: *
Disallow: /product1/*

If the date was in the query part ie www.example.com/product1?date=yyyy-mm-dd you can tell Google to ignore the date argument via Google Webmaster Tools.

Could you make the trade off and move date to query part of URL?
