I'm curious about both the positive and negative benefits of migrating old posts that were written on a Tumblr blog with a custom domain to a self-hosted WordPress solution.
I've seen many people mention better SEO from a self-hosted WordPress solution, as well as the convenience of having all blog content in one place.
If I were to migrate everything to the self-hosted WordPress, I would create 301
redirects from the old post URLs to the new post URLs in order to preserve SEO. However, are there downsides to this? Am I going to experience an SEO hit?
URL example from my old Tumblr blog:
http://blog.example.com
URL example from my new self-hosted WordPress solution:
http://www.websiteurl.com/blog
