Duplicate Title Tags Generating from Previous Owner's Content

Do those pages still exist in any form? If they return a 404 header status then they should automatically be removed eventually. You can check the header status with my tool http://www.jamiestevens.me.uk/headr

If they do return a 404 header status and you do not want to wait for them to be crawled again you can use the remove URLs tool in Google webmaster tools.

Hi thanks for your reply. These pages do not exist anymore and they properly return a 404 status. My ranking is dropping significantly and I think too many duplicate title tags is the major reason behind this.

If I remove them through GWT removal tools, will they stop showing under "duplicate title tags"? Any advise what can I do to prevent more new URLs adding as "duplicate title tags"?

Thank you very much.

If you remove the URLs using the tool they will stop ranking as soon as Google trys to crawl the pages again. This may take a little a little while depending on how many pages are currently linking to the pages that you want removed. Unfortunately there is no way to get them removed with immediate effect, though it is unlikely that a few duplicate title tags will have a huge effect on rankings.
