I have just finished building a 10 domain niche specific PBN my sites are a mix of blogs and some more creative fronts. All proper precautions have been taken to remove/hide footprints. I work with one niche in specific for which i have 5 clients now. If I use the same sites to rank the same group of clients perhaps using a variety for each so I am not using 10 for each client will this not still be an obvious footprint for google to identify ? My fear was sparked after reading a blog post by baeldung (google it i cant post urls yet sorry didnt realise till i tried to post but i think my question still makes sense without the case study) Any thoughts? Do we have to accept PBN's as a churn a burn method for ranking ? Google has recently commented that it is going to treat blog posts as spam links anyway now.. is outreach all we have left for ranking client sites ?
