Hi! My blog all the blog post URL changed, when I'm moving my blog. But my domain name not changed. As a result of that my blog post backlinks are not work. So is it good thing to use permanent redirect to again gain my backlinks and ranking? Because of after my blog move all the previous backlinks now shows "Not Found" error. So permanent redirect is safe method to again gain the ranking? Please help me friends, I'm in a big trouble now. Thanks!
