I have a blog on a custom cms that I want to move to wordpress. I'm going to have to copy and paste all the posts. On wordpress it will be on the same domain, but they will have different file names and locations. How can I do this to aviod duplicate content?
just use a .htaccess file and redirect all the old urls to the new ones. That is the most effective way to move pages permanently. I think you may see a hit in the serps for a few months but it will bounce back.
I'm not worried about the serps. The problem is that I don't know how to do it. The blog has hundreds of pages and I can't put 100s of rules into the .htaccess. The old blog doesn't have the same structure as wordpress.
