I had a website which contains several subdomains.
At present I decided to restructure my website to change all subdomains and links to a different structure like,
Both structures displays same content.
Currently I am using Google Webmaster Tools and most of my webpages are indexed in Google and have some PageRank also.
Before publishing my restructured website, I thought about what are the options that I can preserve my Google rankings as:
- Remove whole old website and publish the restructured website and do the relative changes in Webmaster Tools
- Remove whole old website and publish the restructured website and remove account and recreate new account in Webmaster Tools to restructured website
- Publish restructured website without removing old webpages and use 301 redirect on old pages to its related new webpage.
So what is the best way to publish my restructured website from above options or do I need to do something else to accomplish my goal.
