AttentionSpan on Qbn.com asks:

ive had a site with both www. and without www. indexed so its rather a mess.

Ive decided to keep it without www. did a 301 on htaccess, and put it to preferable in webmaster tools.

Now my question is the site comes up on page 4 with a specific keyword, but its indexed with www. if I remove all indexed sites with www. from Google and submit a new sitemap to Google without www.

How will my placing be on those keywords that i use to get some results with, will it be gone completely and will have to wait a few months to see some new results, or will it just replace the existing www. sites ?

My Advice is:

I wouldnt remove any URL’s, by correcting the canonical issue with GWT then you’re in good stead

It will happen at the same rate as your re-crawl so anything from a few days to a few months. 301 is a good interim workaround and you’ve done the right thing by using webmaster tools.

It’s also beneficial for you to do an inbound link check and make sure your IBL’s are using the correct www. address to link to you! as this is probably the only thing that could maintain your duplication issues.

hope that helps.
