We are nearing completion of a a migration from a self-hosted Movable Type blog to a wordpress.com blog. The migration has involved URL changes due to the way WP.com predefines post and archive URLs. For example, if there is currently an archive page at:
then after the import to wp.com it will look like this:
We intend to buy the domain upgrade so the WordPress site will eventually look like:
I am trying to minimize broken links, search engine errors, etc in this process. A previous post on this topic (now closed—see http://en.forums.wordpress.com/topic/how-to-handle-broken-urls-migrating-from-mt-to-wpcom) suggested setting up a 301 Redirect on the original site for a limited time to help the search engines recognize the new site, and potentially allow some users to update bookmarks.
I would like to take this approach if we can still end up with http://www.emmacarlson.com being the main site. So I have two follow up questions to figure out how this works:
- How long should this 301 Redirect configuration be left in place to allow search engines to recognize the new URL? I know there isn’t a hard number, but a guideline would be helpful – 2 days? A week?
- Once we buy the domain name upgrade, will WordPress similarly redirect so that search engines again “catch up” and use the vanity URL (i.e. http://www.emmacarlson.com rather than emmacarlsondisplaced.wordpress.com)?
The blog I need help with is movabletypeimporttest.wordpress.com.
