I set up a PBN with 5 expired domains last year, TF & CT all 30+ on PR3 to 5's domains. Posted unique articles on with a mix of blank and authority links to cnn, google etc. Posted recently and the articles/links don't seem to be as effective? The domains are sitll registered on Google - so not been indexed but when I test PA, it's way down to single digits from like 30+ Only EVER posted 1 link to the money sites, using only 1 unique relevant keyword per article to money sites, so no 2 links for the same keyword to the same url. They have kept their PR, but I just wondered if there was any way to boost the PBN? To get more PA?? Help I need to make the SEO count.
