We have a client that has two sites that rank well for different searches in their market. The main pages ranking are things like advice articles and news pieces.

For various reasons, they just want one site. I believe they need to duplicate the content from the outgoing site and place it on the main site, with a 301 redirect from each old page to each new one.

What happens when they eventually want to redirect the entire domain? Would these smaller, internal redirects become obsolete, therefore removing any link value they once had?

I am not sure how this works or if there is a best practice way to do this.

Thanks
