To do this, you’d need only have the expired domain hosted, former linked content identified, and then put in place some 301 redirects for the specific content that has the backlinks you want that point to your contributor article. This method effectively siphons the link juice from the expired domain’s top content into the page authority of any of your newer, more relevant links. A riskier approach of this method would be to point the 301 redirect directly towards the website you are trying to rank, though few occasions are seen where this would be advisable.
