Removing pages from index

[tinbum]

My client is running 4 websites on ModX CMS and using the same database for all the sites.

Roger has discovered that one of the sites has 2050 302 redirects pointing to the clients other sites.

The Sitemap for the site in question includes 860 pages.  Google Webmaster Tools has indexed 540 pages. Roger has discovered 5200 pages and a Site: query of Google reveals 7200 pages.

Diving into the SERP results many of the pages indexed are pointing to the other 3 sites.  I believe there is a configuration problem with the site because the other sites when crawled do not have a huge volume of redirects.

My concern is how can we remove from Google's index the 2050 pages that are redirecting to the other sites via a 302 redirect?

The first and the foremost suggestion would be to clean the underlying code and see if you can change the 302s to 301s. Can you post or send via private message the example URLs ?

You might be running into the 302 error due to the system that your site uses to redirect URLs. What CMS or cart is the site built in? A agree with Nakul, that we need to see the underlying code to diagnose the issue.

Thank you gentlemen for your answers.

As per the post the website is built with ModX CMS and the difficulty has come about because the client is using one database to serve 4 websites.  One of the sites has been configured incorrectly and is creating pages that relate to listings on other sites and passing traffic via a 302 redirect.

We're working on fixing the configuration so new pages and 302 redirects are not created.  I want to remove from the index the 2050 302 redirects we've discovered to date.  GWT allows you to remove URLs one at a time although the removal request procedure does not seem appropriate in the situation.

Due to NDA can not publish URL.
