I have been working on a site with a business for 2 years. They now do not require any SEO and therefore no longer need my services. They have asked me to remove the Blog page which contains over 200 blog posts. What I was going to do was create Permanent Redirects for each of the Blog posts and redirect them to my personal site where I will repost the contant. What I want to know is would doing this help my own site with rankings, or would it hurt my site?
