Welcome to the Q&A Forum

I should have explained it what I meant by SERPS better.

These pages are generated by doing a text search on the site. (Magento) So yes, they are product listings, but obviously most queries are different, so the dynamically created pages are all unique but useless.

Thanks for the idea about rel=canonical them back to the search page - I will look into that.

1. Internal Serp pages did not have a robots meta tag

2. As a result, client site has thousands (~4,400) of internal site SERP pages in the Google index.

3. We added the NoIndex, Follow attribute to all internal SERPS

4. We Disallowed: domain.com/internal-search-operator in Robots.txt

5. No new SERP pages are being indexed, but the other 4000 something that were already there are still in the index weeks later.

6. The pages are dynamically created and still work, so I can't use the Remove Content tool from google, because the pages don't 404.

Is there any way to get these pages out of the index besides just waiting and hoping google eventuall drops them?

Thanks
