I have been using a PBN to build links for a client. The client has now stopped paying his bills and therefore I stop building links. I have created a lot of links to his website from a PBN. I want to reuse the content for new clients. I'm going to change the anchor text and only use the content for clients within the same profession. Is it bad practise to I simply just change the anchor text and change the link to another domain? I hope that you some of you have expirence with reusing content in PBN.
