Dear All, I have a website having domain age of 6 months. We redesigned the website and changed the URLs of few pages and deleted some of the pages and posts. Now ranking is dropped and my website is nowhere for the certain keywords and its showing lots of "Not Found Error" in Google Webmasters Tools. Now alexa rank is also falling down day by day. Even I have redirected the old URLs to the new one, but Google is showing "Not Found Error" again and again. I don't have the exact URL list which we have changed and deleted for which Google is showing error. Google is not showing all those URLs at a time which now do not exist. Its showing after each indexation. Can anyone suggest how to retrieve those URLs which not don't exist now and in the past Google has indexed those URLs, so that I could redirect those URLs to new existing URLs? Thanks in advance.
