I changed my wordpress blog’s permalink structure from category/postname to postid/postname by mistake. I know it’s dumb, but I could have sworn I was working on my new blog. Anyways, Google and Yahoo have indexed a large percentage of my blog’s inner pages with the new permalink structure during that time and I changed it back to to the original setting (category/postname) a few days ago.
Looking at the information from Market Samurai, I am losing ranking for many posts that have ranked in the top 5 on Google for their respective keywords. The posts that used to rank 1 and 2 on yahoo still retain the postid/postname permalink structure and most of them no longer rank anywhere.
I guess what I’m trying to ask is, have I fudged this up for good? Will my older blog posts that used to rank well ever regain their rank in the serp?
