Robots.txt file

[gimes]

How do i get Google to stop indexing my old pages and start indexing my new pages even months down the line?

Do i need to install a Robots.txt file on each page?

there should be only one robots.txt file for the entire site. Do you mean "Do I need to add a separate line item within the robots.txt file that disallows each page I want deindexed?" ? The answer is that would not be the best solution.

Other questions need to be asked as well.

1. Have you created a sitemap.xml file with only the new pages in it? And if so, have you submitted that to Google through Webmaster Tools?

2. Have you obtained any off-site links pointing to the new pages?

3. Have you performed a site:mydomain.com search in Google to see whether those new pages have been indexed?

4. Have you checked Google webmaster tools to see whether there are serious errors on your site their system has come across that might be related?

5. Does your site's robots.txt file currently block those new pages from being crawled?

All of these need to be answered to help determine a course of action.

What CMS are you using?  If it is wordpress, there is a plugin that allows you to configure when google is asked to crawl your site and you can set it up so that they only crawl your "archives" monthly and set up how often you have new content on the site.  it is called WP Robots Txt
