In the 114th episode of Semantic Mastery's weekly Hump Day Hangouts, one participant asked about best practices for keeping the backlinks and link juice from an old site to a new one.
The exact question was:
Hi all, one of my clients has a website ranking well, however we are building another new site for them and copying their old site content and articles over. We plan to give the old articles a facelift (making sure it´s optimized well), and updated with new images that are even more relevant for the market today. Both sites are now live, but the old site will soon be closed. We currently link from the old site to the new one, and eventually we will 301 from the old site to the new. Can you give us any tips on this kind of process and work, whats the best way to do this, and make sure all their backlinks copy over, and we maximise link juice etc?
